Answer:
118°
Step-by-step explanation:
because 28 + 90 = 118
Answer:
No, a porportional relationship is not shown
Step-by-step explanation:
Up until 4(x) and 10(y), the relationship is porportional. Then, when x increases by 2, y also only increases by 2. Y would need to increase by 5.
Y - 1 = 4y - 2/3. Move the ys over to one side, +4y crosses over to become -4y,
and -1 crosses over the right side to become +1.
y -4y = -2/3 + 1
-3y = 1 - 2/3
-3y = 1/3 Divide both sides by -3.
-3y/-3 = (1/3) / -3.
y = 1/3 * -1/3
y = - 1/9
Answer:
B) (8, 0) and (-4,0)
Step-by-step explanation:
x-intercept when y = 0
so
x^2 - 4x - 32 = 0
Factors
(x - 8)(x + 4 ) = 0
x - 8 = 0; x = 8
x + 4 = 0; x = -4
(8, 0) and (-4,0)
