Solve for x: −3 |x + 7| = −12

Answers

Answer 1

[tex]-3|x + 7|=-12\quad |:(-3)\\\\|x+7|=4\\\\\\x+7=-4\qquad\vee\qquad x+7=4\\\\x=-4-7\qquad\vee\qquad x=4-7\\\\\boxed{x=-11\qquad\vee\qquad x=-3}[/tex]

Answer 2

first you divide both sides by -3
then you get |x + 7| = 4
what you do now is make two separate equations
drop the absolute value signs
x + 7 = 4 OR x + 7 = -4
subtract 7 from both sides AND BOTH EQUATIONS
x = -3 OR x = -11

lets check it!

-3 |-3 + 7| = -12 -3 |-11 + 7| = -12
-3 |4| = -12 -3 |-4| = -12
-3 (4) = -12 -3 (4) = -12

yep! your answers are x = -3 OR x = -11

i hope this helps!!

HELP!!!!!!!! PLZ!!!!!!!!WILL GIVE BRAINLIEST!!!!!!!! :)
Lia must work at least 5 hours per week in her family’s restaurant for $8 per hour. She also does yard work for $12 per hour. Lia’s parents allow her to work a maximum of 15 hours per week overall. Lia’s goal is to earn at least $120 per week.

1.)Write a system of inequalities to represent this situation. Let r be the number of hours worked at the restaurant, and let y be the number of hours of yard work.
2.)Graph the inequalities.
3.)What is the maximum number of hours Lia can work at the restaurant and still meet her earnings goal? Explain.
4.)What is the maximum amount of money Lia can earn in 1 week? Explain.

Answers

(1) r+y<=15
r>=5
8r+12y>=120
(3) assuming she will work 15 hours, y = 15-r
so
8r + 12(15-r) >= 120
8r+180-12r>=120
-4r+180>=120
-4r >= -60
r <= 15
looks like she could work all 15 hours and still make 120 dollars
(4) r= 5 required hours in the restaurant then
8r + 12(15-r)= 160

5. The dimensions, in inches, of a shipping box at We Ship 4 You can be expressed as width x, length x + 5, and height 3x - 1. The volume is about 7.6 f3. Find the dimensions of the box in inches. Round to the nearest inch. (Hint: 1 f 1,728 in.3)

Answers

Final answer:

To find the dimensions of the shipping box, calculate the volume in cubic inches, then set up and solve the volume equation x(x + 5)(3x - 1), substituting the given volume after conversion from cubic feet. Solve for x, then use it to find and round the box's dimensions.

Explanation:

To find the dimensions of the shipping box, we need to calculate the volume using the given dimensions in inches and compare it to the provided volume in cubic feet. Recall that the conversion factor between cubic feet and cubic inches is 1 cubic foot equals 1,728 cubic inches. Firstly, convert the volume of the box from cubic feet to cubic inches: 7.6 cubic feet are 7.6 x 1,728 cubic inches.

Next, we can set up the volume equation for the box using the given dimensional expressions: volume = width x length x height, which for this box is x x (x + 5) x (3x - 1). Now we solve the equation for x given that the volume in cubic inches is equal to 7.6 x 1,728 inches.

Once x is found, we can determine the width, length, and height by plugging x back into the expressions x, x + 5, and 3x - 1, respectively, and rounding each to the nearest inch.

How do I do proofs? What’s the next step

Answers

Since they are vertical angles, that means that ∠AOB+∠BOZ=180 and ∠ZOX+∠AOX=180 too. Next, ∠AOB+∠AOX=180 (supplementary angles), as well as ∠BOZ+∠ZOX.
∠AOB+∠AOX=180
∠ZOX+∠AOX=180
Subtracting the first equation from the second, we get ∠ZOX-∠AOB=0. Adding ∠AOB to both sides, ∠AOB=∠ZOX=6x+5=80. Subtracting 5 from both sides, we get 6x=75 and x=12.5 by dividing both sides by 6

What is the equation of the quadratic function with roots -3 and 1 and a vertex a (-1, -8)?

Answers

Start with the equation of a vertical parabola: y-k = a(x-h)^2. We are told that the coordinates of the vertex are -1 and -8. Substituting these into the above equation,

y-[-8] = a(x-[-1]), or y+8 = a(x+1)^2. The coefficient a is undetermined here. How do we find it?

At any root, y=0, as a "root" is a point at which the graph crosses the x-axis.

Thus, if we choose to work with the given root 1, the associated point is (1,0). Substitute these coordinates into the above equation y+8 = a(x+1)^2.

We get 0+8 = a(1+1)^2, or 8 = a(2)^2, or 8 = 4a, or a = 2.

Substituting this value for a into the above equation,

y+8 = 2(x+1)^2.

You should check this result by determining whether the other root (-3,0) satisfies this equation. If yes, then you'll know for certain that this equation correctly describes the parabola in question.

Which of the binomials below is a factor of this trinomial?

x2 + 13x + 42

A. x - 7
B. x + 7
C. x + 84
D. x2 + 12

Answers

First factor x² + 13x + 42.

x² + 6x + 7x + 42

x(x + 6) + 7(x + 6)

The factors are : (x + 7)(x + 6)

Solution: B. x + 7

The trinomial x^2 + 13x + 42 factors into (x + 7)(x + 6), making x + 7, which is option B, the correct binomial factor of the trinomial.

To determine which binomial is a factor of the trinomial x2 + 13x + 42, we need to factor the trinomial. To factor the trinomial, we are looking for two numbers that multiply to give us the constant term (42) and add to give us the linear coefficient (13). These two numbers are 7 and 6 because 7 * 6 = 42 and 7 + 6 = 13.

So, we can factor the trinomial as (x + 7)(x + 6). Thus, the binomial that is a factor of x2 + 13x + 42 is x + 7, which is option B.

What type of endorsement is illustrated by the following example: Tom Ash 7609-25-26-3 A) Restrictive endorsement B) Full endorsement C) Blank endorsement D) Signature endorsement

Answers

The answer is letter c which is blank endorsement. It is a sign by the maker of an instrument, for instance a check, which allows any holder of the instrument to declare a claim for payment. Since no payee is stated, such an endorsement fundamentally turns the instrument into a bearer security.

Final answer:

The example given 'Tom Ash 7609-25-26-3' indicates a blank endorsement, which is when the original holder of a negotiable instrument signs their name without naming a new payee or providing other instructions, making the instrument payable to the bearer.

Explanation:

The type of endorsement illustrated by 'Tom Ash 7609-25-26-3' is a blank endorsement. In a blank endorsement, the holder of a negotiable instrument, such as a check, simply signs their name on the back of the instrument without specifying the new payee or any other instructions. This means that the instrument becomes payable to the bearer and can be transferred merely by delivery. The other types of endorsements include restrictive, full, and signature endorsements, but since there are no additional instructions or named endorsee next to the signature, it does not qualify as any of those.

Final answer:

The question wants to find the value of x when f(x) equals 25. The exact value cannot be determined without the clearly defined function f(x). The value of x can vary depending on the definition of the function.

Explanation:

This is a function notation question where you want to find the value of x when f(x) equals 25. The information provided is not sufficient to determine the exact value of x since the function f(x) is not clearly defined. Depending on the function definition, the value of x when f(x) = 25 can vary. For example, if the function is f(x) = 0.25e(-0.25x), then the value of x would be calculated differently than if the function was f(x)=5x or f(x)=x^2. I'd recommend checking your question again and confirming the function's correct formula or equation for an accurate solution.

Answers

This is a two-part algebraic equation, meaning there are two consistent factors of different amounts. Since time (t I'll say) will always remain a constant factor, the equation will look like: 55(t) + 70(t) = 375

To find (t) or time, you will want to start by combining like terms, so that the equation is: 125(t) = 375

Dividing the equation by 125 so that (t) will be separated from all other factors

A box of cookies can hold 24 cookies, and a container can hold 75 boxes of cookies. write a program that prompts the user to enter the total number of cookies, the number of cookies in a box, and the number of cookie boxes in a container. the program then outputs the number of boxes and the number of containers to ship the cookies. note that each box must contain the specified number of cookies, and each container must contain the specified number of boxes. if the last box of cookies contains less than the number of specified cookies, you can discard it and output the number of leftover cookies. similarly, if the last container contains less than the number of specified boxes, you can discard it and output the number of leftover boxes.

Answers

Final answer:

The provided math problem involves writing a program that helps to calculate the number of cookie boxes and containers required to ship a specific number of cookies considering the capacity of each item. If there are leftover cookies that do not fill a box or if there are leftover boxes that do not fill a container, these are also calculated.

Explanation:

This is a programming problem which requires logic to calculate the number of boxes and containers needed to ship a given number of cookies. Assume that 'total_cookies', 'cookies_per_box', and 'boxes_per_container' are user inputs. Initially, you should calculate the total boxes by 'total_boxes = total_cookies / cookies_per_box'. The floored division operator is applied to discard the last box if it contains less than the specified number of cookies. Then, calculate the total containers with 'total_containers = total_boxes / boxes_per_container'. Again, you use the floored division operator to discard the last container if it contains less than the specified number of boxes. Lastly, calculate the leftover cookies and boxes, which is done by applying the modulus operator. 'leftover_cookies = total_cookies % cookies_per_box' and 'leftover_boxes = total_boxes % boxes_per_container'.

The logic of the given program focuses on the calculation of boxes and containers needed to ship the given number of cookies keeping in consideration the capacity of each box and container. Also, the algorithm calculates the leftover cookies and boxes, if not enough to fill a box or container fully.

The perimeter of a rectangular concrete patio is 34 meters. the area is 70 square meters. what are the dimensions of the patio?

Answers

Final answer:

To find the dimensions of the rectangular patio, use the equations for perimeter and area and solve for length and width.

Explanation:

To find the dimensions of the rectangular patio, we can use the given information about its perimeter and area. Let's assume the length of the patio is L and the width is W.

The perimeter is given as 34 meters, which is equal to 2L + 2W. So, we have the equation 2L + 2W = 34.

The area is given as 70 square meters, which is equal to L * W. So, we have the equation L * W = 70.

We can use these equations to solve for L and W using substitution or elimination method.
