the slope is 1.8

Answer:

The slope is 1.8

Step-by-step explanation:

m=9/5=1.8

Answer: 3/4

Step-by-step explanation:

To take this ratio to its simplest form, we have to divide by a value divisible by the numerator and denominator.

3 is a divisible value, therefore,

9/12 = 9 ÷ 3 = 3

12 ÷ 3 = 4

Thus, 9/12 = 3/4

Answer:

y = -5

Step-by-step explanation:

x= (-22+2y)/4 = -3+y

-22+2y = 4(-3+y)

-22+2y = -12+4y

-22+12 = 4y-2y

-10 = 2y

-10/2 = y

-5 = y

Answer:

x = -8

y = -5

Step-by-step explanation:

From the given expression, let's make two equations

4x   -   2y =   - 22--------------------------(i)

-x    +   y  =     3-----------------------------(ii)

to easily substitute, lets make another equation from equation (ii)

y  =  3  +   x

substitute (y=3+x) in equation (i)

4x   -   2 (x+3)   =   -22

4x  -   2x   -  6   =   -22

2x  -  6   =   -22

2x       =   -22   +  6

2x    =  -  16

x   = -16  /  2

x  =   -  8

lets solve for (y) by substituting   (x =  - 8) in equation   (ii)

-  (- 8)  +  y = 3

8  +  y  =   3

8  +  y  = 3

y  =  3  -  8

y  =  -  5

Therefore:

x  =  -  8

y  =  -  5

Answer:

Yes, this is true.

Step-by-step explanation:

If you substitue x for -1 you get -3(-1+8)=-21, Then you add -1 and 8 so you should get 7. After, you multiply 7 times -3 you get -21. Proving this statement is correct.

Answer:

See below.

Step-by-step explanation:

We can solve for x:

−3(x+8) = −21

Distribute the -3 over the parentheses:

-3x - 24 = -21

Add 24 to both sides:

-3x -24 + 24 = -21 + 24

-3x = 3

Divide both sides by -3:

x = -1.

So that proves the original equation.

(0, 7 )

Step-by-step explanation:

Where the line crosses the y- axis the x- coordinate of the point is zero.

Substitute x = 0 into the equation and evaluate for y

y = - 3(0) + 7 = 0 + 7 = 7 ⇒ (0, 7 )

Step-by-step explanation:

15% as a decimal is 0.15

40*0.15 is 6

6 guests arrive early

6 people arrive early to the party.

Calculating the Number of People Who Arrive Early to a Party

To calculate the number of people who arrive early to a party where 40 people are expected, we use the given percentage of guests that arrive early, which in this case is 15%. The calculation process is straightforward:

Convert the percentage to a decimal by dividing by 100, which gives us 0.15.

Multiply the decimal by the total number of people expected at the party to find the number of people who arrive early.

So, the calculation is:

0.15 x 40 = 6

Therefore, 6 people arrive early to the party.

Answer:

1/5

Step-by-step explanation:

because there is 10 coins and two specific coind you are trying to get and 2/10 simplified is 1/5

The probability that the two randomly selected coins from Reyna's collection will total at least 15 cents is 8/45.

Probability Calculation

To determine the probability that Reyna's two randomly selected coins will total at least 15 cents, we must first calculate the total number of possible outcomes when choosing two coins from the ten that she has (7 nickels and 3 dimes).

Using the combination formula, which is C(n, k) = n! / [k!(n-k)!], we find that the total number of ways to choose 2 coins from 10 is C(10, 2) = 10! / (2!8!) = 45.

The favorable outcomes in this scenario are cases where Reyna picks either two dimes or one nickel and one dime. There is only one way to pick two dimes, and there are 7 ways to pick one nickel and one dime (because she could pick any of her 7 nickels along with one of the 3 dimes). So, there are 7 + 1 = 8 favorable outcomes.

The probability of picking coins that total at least 15 cents becomes the number of favorable outcomes divided by the total number of outcomes, which is 8/45.

Therefore, the probability that the two coins together will be worth at least 15 cents is 8/45.

Answer:

(6, 9 ) and r = 3

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + y² - 12x - 18y + 108 = 0

Rearrange the x- terms and the y- terms together and subtract 108 from both sides, that is

x² - 12x + y² - 18y = - 108

To obtain standard form use the method of completing the square

add ( half the coefficient of the x and y terms )² to both sides

x² + 2(- 6)x + 36 + y² + 2(- 9)y + 81 = - 108 + 36 + 81

(x - 6)² + (y - 9)² = 9 ← in standard form

with centre = (6, 9 ) and r = [tex]\sqrt{9}[/tex] = 3

Answer:

For x=20: difference is 22

Step-by-step explanation:

For f: y increased 5 units (from 1 to 6) when x went from 0 to 10. Being linear, when x=20, f will increase with another 5 units, being 6+5=11.

For g: g(20)=1.5×20+3=33

So, for x=20, f(20)-g(20)=11-33=-22

So the difference is 22.

Answer:

15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%

Let X be the naked price

Paid = marked price - discount

Paid = X - (15/100 × X)

Using distribution property,

Paid = X(1 - 15/100)

Paid = X[(100-15)/100]

Paid = X(85/100)

Which is 85/100 × X

Hence 85% of X

Answer: 85% = 0.85

While 15% = 0.15

Step-by-step explanation:

Percentage is a fraction whose denominator is 100. So if we say 15%, we mean 15/100 = 0.15.

If want to find 15% of a 100, it means 15% of 100 = 15/100 × 100 = 15.

To find 85 % of 100 means 85/100 × 100= 85

hence subtraction of 15% from 100% is 85%

Therefore 15% = 15/100 = 0.15

While 85% is 85/100 = 0.85

The given function is even.

Solution:

Given function:

[tex]f(x)=x^{6}-x^{4}[/tex]

If f(-x) = -f(x), then the function is odd.

If f(-x) = f(x), then the function is even.

[tex]f(x)=x^{6}-x^{4}[/tex]

Substitute x = -x

[tex]f(-x)=(-x)^{6}-(-x)^{4}[/tex]

          [tex]=x^{6}-x^{4}[/tex]

          = f(x)   (given)

   f(-x) = f(x)

From the definition, it is even.

Hence the given function is even.

Step-by-step explanation:

Here we have , 10-ounce package of cashews costs $8.11, and a 16-ounce package of cashews costs $12.  

a. What is the cost per ounce for the 10-ounce package of cashews?

​cost per ounce for the 10-ounce package of cashews = [tex]\frac{8.11}{10}[/tex]

​cost per ounce for the 10-ounce package of cashews = $[tex]0.811[/tex]

b. ​What is the cost per ounce for the 16-ounce package of cashews?

cost per ounce for the 16-ounce package of cashews = [tex]\frac{12}{16}[/tex]

cost per ounce for the 16-ounce package of cashews = $[tex]0.75[/tex]

c. Which package is the better buy?

10-ounce package of cashews costs $8.11 is better then a 16-ounce package of cashews costs $12 , because cost per ounce for the 10-ounce package of cashews = $[tex]0.811[/tex] is greater then cost per ounce for the 16-ounce package of cashews = $[tex]0.75[/tex]

The cost per ounce for the 10-ounce package of cashews is $0.811, and the cost per ounce for the 16-ounce package is $0.75. The 16-ounce package is the better buy.

a. To find the cost per ounce for the 10-ounce package of cashews, we divide the total cost by the number of ounces. $8.11 ÷ 10 ounces = $0.811 per ounce.

b. To find the cost per ounce for the 16-ounce package of cashews, we divide the total cost by the number of ounces. $12 ÷ 16 ounces = $0.75 per ounce.

c. The better buy is the package with the lower cost per ounce. Therefore, the 16-ounce package of cashews is the better buy.

The coordinates for the shape are;

a = (0, 0), b = (a, 0), c = (a, a), and d = (0, a).

Step-by-step explanation:

Step 1:

First, we must assign letters to the four vertices of the given shape.

Assume the lower-left vertex is a, the lower-right vertex is b, the upper-right vertex is c and the upper-left vertex is d.

So the vertices for the shape are a, b, c, and d.

Step 2:

The coordinates for a point on a graph is given by (x coordinate, y coordinate).

So we need to determine the x and y coordinates for the four points on the shape abcd.

Step 3;

The x coordinate for vertex a = 0, the y coordinate for vertex a = 0,

so the coordinates of vertex a = (0, 0).

The x coordinate for vertex b = a - 0 = a, the y coordinate for vertex b = 0,

so the coordinates of vertex b = (a, 0).

The x coordinate for vertex c = a- 0 =a, the y coordinate for vertex c = a- 0= a, so the coordinates of vertex c = (a, a).

The x coordinate for vertex d = 0, the y coordinate for vertex d = a - 0 =a,

so the coordinates of vertex d = (0, a).
