**Answer:**

C.

**Step-by-step explanation:**

11 is a prime number, meaning that its only factors are 1 and itself.

**Answer:**

y = -2x+16

**Step-by-step explanation:**

The line has a y intercept at 16 (This is where it crosses the y axis)

The slope is found by using

m = (y2-y1)/(x2-x1)

We have two point (0,16) and (8,0)

m = (0-16)/ (8-0)

= -16/8

= -2

We can use the slope intercept form of a line

y= mx+b where m is the slope and b is the y intercept

y = -2x+16

<h2>

** x = 78 **</h2>

**Step-by-step explanation:**

**Answer:**

Turn them over

both sides

**Step-by-step explanation:**

**Answer:**

x = 17

**Step-by-step explanation:**

Given equation:

(6x + 3) + 75 = 180

Subtract 75 from both sides:

⇒ (6x + 3) + 75 - 75 = 180 - 75

⇒ 6x + 3 = 105

Subtract 3 from both sides:

⇒ 6x + 3 - 3 = 105 - 3

⇒ 6x = 102

Divide both sides by 6:

⇒ 6x ÷ 6 = 102 ÷ 6

⇒** x = 17**
