Answer:
91°
Step-by-step explanation:
x and 89 are linear equations
180 - 89 = 91
x = 91
2d = 5c
2/5 = c/d ...true
5/2 = d/c...true
2/c = 5/d...true
2/d = 5/c....not true
Greater than or equal to 8
Answer:
B, 6
Step-by-step explanation:
In the equation (x - c)² + (y - d)² = r², (c, d) is the center and r is the radius. In this case, c = -2, d = 7 and r = 6 so the center is (-2, 7) and the radius is 6.
Answer:
y = 7/2x - 15
Step-by-step explanation:
y = mx + b
if slope is 7/2, m= 7/2
y = 7/2x + b
if y-intercept is -15, y = -15, x = 0
-15 = 7/2(0) + b
b = -15
then
y = 7/2x - 15
