Step-by-step explanation:

Answer:

y=1/4x+3

Step-by-step explanation:

Answer:

The equation of the line is:

[tex]y = 4x + 3[/tex]

Step-by-step explanation:

We know that the slope-intercept of line equation is

[tex]y = mx+b[/tex]

Where m is the slope and b is the y-intercept

Given the two points on a line

Finding the slope between (0, 3) and (-2, -5)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-5\right)[/tex]

[tex]m=\frac{-5-3}{-2-0}[/tex]

[tex]m=4[/tex]

We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.

From the graph, it is clear:

at x = 0, y = 3

Thus, y-intercept = b = 3

Substituting m = 4 and b = 3 in the slope-intercept form of line equation

[tex]y = mx+b[/tex]

[tex]y = 4x + 3[/tex]

Therefore, the equation of the line is:

[tex]y = 4x + 3[/tex]

Answer:

Step-by-step explanation

8(-1)^4-3(-1)-7= ?

multiply 8 * -1= -8

so -8^4= 4096 that part is done.

now do -3 * -1 and get 3 because two neg. = posit.

so now the question should say

4096+3-7=?

4096+3= 4099-7= 4092

x=4092 i think unless that isnt what you are doing im srry if this is incorrect i tryed and i hope this is correct...again im srry if this is incorrect

Answer:

4

Step-by-step explanation:

8(-1)^4=8

-3(-1)=3

8+3-7=4

Answer:

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Step-by-step explanation:

Given

The attachment

Required

Express the area as a sum of stores and parking lots

First, calculate the area of the stores

[tex]Store\ A = 25\ by\ 10[/tex]

[tex]Store\ B = 25\ by\ w[/tex]

[tex]Stores\ A\ and\ B = 25\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_1 = 25 * (10 + w)[/tex]

Next, calculate the area of the parking lots

From the attachment, we have the following

[tex]Parking\ lot\ A = 13.5\ by\ 10[/tex]

[tex]Parking\ lot\ B = 13.5\ by\ w[/tex]

[tex]Parking\ lots\ A\ and\ B = 13.5\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_2 = 13.5 * (10 + w)[/tex]

The area of the shopping centre is then calculated as:

[tex]Area = A_1 + A_2[/tex]

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Answer:

4/8 more pounds

Step-by-step explanation:

7/8-3/8=4/8

Answer:

Jon ate 5/8 more pounds of blueberries than Meg.

Step-by-step explanation:

This is because the question is asking for the difference between how many blueberries Meg ate, and how many Jon ate. Therefore, we have to use subtraction.

7/8 - 3/8 = 5/8, therefore Jon ate 5/8 lb more than Meg.

Answer:

i'm not good at algebra but i think it's  5

Step-by-step explanation:

Answer:

80

Step-by-step explanation:

Answer:

32 times

Step-by-step explanation:

It's SUPER easy, all you have to do is take that 1/8 and make it into a regular 8. Now all you do is multiply 4 by 8.

I know there's probably some way the teachers taught that's so much harder then it already is, but if you try to look at it from an easier perspective, you'll be a pro!

Try some more so you'll slowly start getting better at them! Anyway I hope this helped!!

Answer: 12n + 60

Step-by-step explanation:

So first you have to distribute the 5 in the parentheses.

(5)(n + 12) = 5n + 60

5n + 60 + 7n

Then add like terms.

12n + 60

1/2 gallon =2 quarts, so add the 2 quarts and the 1 quart of ginger ale, plus the one pint of lemonade and this makes 14 cups of punch

Answer:

x = 12

y = 16

Step-by-step explanation:

Use the Pythagoras Theorem on the left triangle.

[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(x)^2=(7.2)^2+(9.6)^2\\x^2=51.84+92.16\\x^2=144\\x=\sqrt{144}\\x=12\\[/tex]

Now use the Pythagoras Theorem on the right triangle.

[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(y)^2=(12.8)^2+(9.6)^2\\y^2=163.84+92.16\\y^2=256\\y=\sqrt{256}\\y=16\\[/tex]

Answer:

Equation: x × -2 = y

Solution: y = 12

Step-by-step explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.

Answer:

a. 70%

b. 6 more times

c. subtract from 100% with percentages, subtract from 1 with decimals.

Step-by-step explanation:

a. To find the percentage of red and yellow, skip back the decimal point two times: 0.26 > 26%     0.04 > 4%

Add all of the percentages together to get 70%

b. To find how many times more students said red than yellow, divide yellow from red. It shows you how many times yellow can go into red, giving you the correct answer.

0.26 ÷ 0.04

26 ÷ 4

6

c. 14% + 26% + 40% + 4% = 84%

100% - 84%

16%

(do the same thing with decimals and pick your favorite method)
