Answer:

(5,1)

Step-by-step explanation:

4x + 7•(x /4-1/4) = -13

   -9x/4 = -45/4

   -9x = -45

Solve equation for the variable  x

 9x = 45

  x = 5

By now we know this much :

x = 5

   y = x/4-1/4

Use the  x  value to solve for  y

   y = (/4)(5)-1/4 = 1

butalik [34]
The angles when added equal180
therefore:
x+x+(x+45)= 180
3x+45=180
3x=180-45
3x=135
x=135/3
x=45
therefor the angles
are 45, 45, 90 degrees

Your guinea pig is five inches more than half your snake's length. If your guinea pig is 47 inches how long is your snake?
vagabundo [1.1K]
G = 1/2s + 5
g = 47

47 = 1/2s + 5
47 - 5 = 1/2s
42 = 1/2s
42 * 2 = s
84 = s.....so the snake is 84 inches

Choose the correct solution and graph for the inequality.
Maslowich

D. x is greater than or equal to -8

Explanation:

The inequality given by the problem is:

-\frac{x}{4} \leq 2

In order to solve it, we must do the following steps:

- Multiply by 4 on both sides of the inequality:

-\frac{x}{4} \cdot 4 \leq 2 \cdot 4\\-x \leq 8

- Change the sign of both sides: when doing this step, we must reverse the sign of the inequality:

-x \leq 8\\x \geq -8

So, the correct option is

D. x is greater than or equal to -8
