Answer:
a. A
b. B
c. D
d. E
e. C
Step-by-step explanation:
Linear pairs are supplementary, so ...
∠2 = 180° -∠1 = 180° -130° = 50° . . . (a)
∠6 = 180° -∠7 = 180° -70° = 110° . . . (d)
Vertical angles are congruent, so ...
∠5 = ∠7 = 70° . . . (c)
Exterior angles are equal to the sum of the opposite interior angles, so ...
∠4 = ∠2 +∠5 = 50° +70° = 120° . . . (e)
__
∠1 = ∠3 +∠5
130° = ∠3 +70°
∠3 = 130° -70° = 60° . . . (b)
Answer:
12x² - 4x - 8
Step-by-step explanation:
Use FOIL method
(3x + 2)(4x - 4) = 3x*4x + 3x*(-4) + 2 *4x + 2*(-4)
= 12x² - 12x + 8x - 8 {add like terms}
= 12x² - 4x - 8
Hint: 3x * 4x -----> Multiply the coefficients = 3 *4 = 12 and then multiply the variables and for multiplying the two variable, add the powers
x*x =
3x * 4x = 12x²
The range is ur f(x) values and ur domain is ur x values.
f(x) = 4x - 9...when domain (x) is -3
f(-3) = 4(-3) - 9
f(-3) = -12 - 9
f(-3) = - 21
f(x) = 4x - 9...when domain (x) = 0
f(0) = 4(0) - 9
f(0) = -9
f(x) = 4x - 9...when domain (x) is 5
f(5) = 4(5) - 9
f(5) = 20 - 9
f(5) = 11
so ur range is { -21,-9,11} <==
