Answer:
5=135
7=45
Step-by-step explanation:
Set them equal to 180. So i started plugging in numbers and subtracting them by 90. Then add it back to the number until i got 180.
1) 8(3a+6) = 9(2a-4)
First, we use distributive property on both sides.
Once we do this, we get:
24a + 48 = 18a - 36
Add 36 to each side.
24a + 84 = 18a
Subtract 24a from each side.
84 = -6a
Divide each side by -6
-14 = a
2) 6(2x-8)+3 = 15
Again, we use distributive property:
12x-48+3 = 15
Subtract 3 from each side
12x - 48 = 12
Add 48 to each side
12x = 60
Divide each side by 12
x = 5
3) -5(3x+6) = -3(4m-2)
Distributive property:
-15m - 30 = -12m + 6
Add 30 to each side
-15m = -12m + 36
Add 12m from each side
-3m = 36
Divide each side by -3
m = -12

Answer:
B
Step-by-step explanation:
Given
x² + 3x + 2 = 0
To factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are 2 and 1, since
2 × 1 = 2 and 2 + 1 = 3, thus
(x + 2)(x + 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1
Answer A) is correct because it states that the slope is the same which is -3 and has the same y-intercept (Initial Value) which is 4.5 for both.
Step-by-step explanation:
Slope is -3 for Item 1 and Item 2
Y-Intercept is 4.5 for Item 1 and Item 2
