what is the slope intercept form of the linear equation 4x + 2y = 24
drag and drop the appropriate number, symbol, or variable to each box

Answers

The answer is: y = -2x+12

4x+2y=24=

4x-4x+2y=24-4x=

2y=24-4x

Divide each piece by 2=

2y/2=24/2-4x/2

y=12-2x

But, slope intercept form is y=mx + b so you must put the second part in reverse, making the answer to the equation be y=-2x+12

4(4x+3)=19x+9-3x+3 what are the steps

Answers

Ok so:

4(4x+3) = 19x + 9 - 3x +3
parenthesis first:
4 x 4x = 16x then 4 x 3 = 12

16x + 12 = 19x + 9 - 3x + 3
combine :) :
19x - 3x = 16x then 9 + 3 = 12

16x + 12 = 16x +12
-12 -12
16x = 16x
They are the same equations lol they equal 0.

The steps of the expression are given below.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 4 (4x + 3) = 19x + 9 - 3x + 3

Now,

Solve the expression as;

The expression is,

⇒ 4 (4x + 3) = 19x + 9 - 3x + 3

⇒ 16x + 12 = 19x + 9 - 3x + 3

⇒ 16x + 12 = 16x + 12

⇒ 16x - 16x = 12 - 12

⇒ 0 = 0

Thus, The steps of the expression are given below.

If you know the DP rule then if you see a percent move it two spaces to the right to make it a decimal so 15% is actually .15 as a decimal multiply .15 and 14 and that should give you 2.1. Because it is a discount you subtract 2.1 form 14. 14-2.1 is 11.9

There are two sizes of trucks available: larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload. To unload a freight train 21 larger trucks are needed . How many smaller trucks would be needed for the same job?

Answers

You can find the answer to this question by multiplying 21 by 2.5 to find the total weight ton which would be 52.5, then you would divide 52.5 by 1.5 to find the number of small trucks needed to equal 52.5 ton which would be 35 smaller trucks. So your answer should be 35 smaller trucks are needed to do the same job.

Given A = {18, 6, -3, -12} Determine all elements of set A that are in the solution of the inequality 2/3x + 3 < -2x -7

Answers

Plug in each value in the set into x, and evaluate both sides.
The values of x that make the inequality true are the answer.

Start with 18.
2/3x + 3 < -2x -7
2/3(18) + 3 < -2(18) - 7
12 + 3 < -36 - 7
15 < -43 is false, so 18 does not work.

Now do 6.
2/3x + 3 < -2x -7
2/3(6) + 3 < -2(6) - 7
4 + 3 < -12 - 7
7 < -19 is false, so 6 does not work.

Now do -3.
2/3x + 3 < -2x -7
2/3(-3) + 3 < -2(-3) - 7
-2 + 3 < 6 - 7
1 < -1 is false, so -3 does not work.

Now do -12.
2/3x + 3 < -2x -7
2/3(-12) + 3 < -2(-12) - 7
-8 + 3 < 24 - 7
-5 < 17 is true, so -12 does not work.

solve by substitution ! show work pls !!

Answers

When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.

For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.

3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)

Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11

A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random. What is the theoretical probability of picking a green marble

Answers

So, if the jar has 20 yellow marbles, 55 green marbles, and 25 purple marbles in total it has 100 marbles. (check:20+55+25=100m). Sense there are 55 green marbles out of 100, your theoretical probability will be 550/100(fraction:55 over 100). Simplified its 11/20.

Answer:

The theoretical probability of picking a green marble is 0.55. Step-by-step explanation:

Given : A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random.

To find : What is the theoretical probability of picking a green marble?

Solution :

Theoretical probability is defined as the number of favorable outcome divided by total number of outcome.

Yellow Marble = 20

Green Marble = 55

Purple Marble = 25

Total Number of marble = 20 + 55 + 25 = 100

Let G be the event of getting green marble.

So, Favorable outcome = 55

Theoretical probability of picking a green marble is

[tex]P(G)=\frac{55}{100}[/tex]

[tex]P(G)=\frac{11}{20}[/tex]

[tex]P(G)=0.55[/tex]

Therefore, The theoretical probability of picking a green marble is 0.55.

At one college, GPA's are normally distributed with a mean of 2.7 and a standard deviation of 0.5. What percentage of students at the college have a GPA between 2.2 and 3.2?

Answers

Final answer:

About 68.27% of students at the college have a GPA between 2.2 and 3.2 because these values correspond to z-scores of -1 and +1, respectively, in a normal distribution.

Explanation:

To find the percentage of students at the college who have a GPA between 2.2 and 3.2, we will use the properties of the normal distribution. The mean GPA is 2.7 and the standard deviation is 0.5.

First, we calculate the z-scores for the GPAs of 2.2 and 3.2:

z-score for 2.2 = (2.2 - 2.7) / 0.5 = -1

z-score for 3.2 = (3.2 - 2.7) / 0.5 = +1

The z-score represents the number of standard deviations a data point is from the mean. In a standard normal distribution, the percentage of data between z-scores of -1 and +1 is approximately 68.27%.

Therefore, about 68.27% of the students at the college have a GPA between 2.2 and 3.2.

Use the substitution method to solve the given system of equations. -6y+18=12x and y=3-2x

Answers

We are given that y = 3 - 2x

We will substitute with this value in the second equation as follows:
-6y + 18 = 12x
-6 (3-2x) + 18 = 12x
-18 + 12x + 18 = 12x
This will give us zero = zero

A 0=0 solution means that the system has infinitely many solutions.

Therefore, the answer is (c)

Find the domain and range of x + y = 1. Then determine whether it is a function.

Answers

The domain is all real numbers and the range is all real numbers.
(-∞, ∞) for both.

It is a function.

Final answer:

The domain and the range of the equation x + y = 1 are both all real numbers. The equation is a function since each x-value corresponds to a unique y-value.

Explanation:

The question is asking us to find the domain and range of the equation x + y = 1, and to determine whether it is a function.

The domain of an equation is the set of all possible x values. For this equation, we can substitute any real number for x, therefore, the domain is all real numbers.

The range of an equation is the set of all possible y-values. In this equation, for any given value of x, there will be a corresponding value of y (y = 1 - x). Therefore, the range of the equation is also all real numbers.

Whether an equation defines a function or not depends on whether each x-value corresponds to a unique y-value. For this equation, each x-value does correspond to a unique y-value, so it is indeed a function.
