5a)
2x + 94 = 7x + 49 (vertical angles are equal)
2x - 7x = -94 + 49
-5x = -45
x = 9
Answer
9
5b)
4y + 7x + 49 = 180 (supplementary angles, sum = 180)
4y + 7(9) + 49 = 180
4y + 112 = 180
4y = 68
y = 17
Answer
17
6)
x = 6x - 290 (vertical angles are equal)
-5x = -290
x = 58
Answer
58
Answer:
f(5) = -36
Step-by-step explanation:
Plug in 5 as x:
f(x) = −6(x + 1)
f(5) = -6(5 + 1)
Simplify:
f(5) = -6(6)
f(5) = -36
So, f(5) = -36
Answer: Melinda’s loan will be equal to the value of the car after 10 months.
Step-by-step explanation:
Hi, to answer this question we have to equal both equations:
Melinda’s loan will be equal to the value of the car
y = y
10,000 – 250x = 8,000 – 50x
Solving for x:
10,000-8,000 = -50x+250x
2,000 = 200x
2,000/200 =x
10 = x
Melinda’s loan will be equal to the value of the car after 10 months.

Step-by-step explanation:
Answer:
8/125
Step-by-step explanation:
Given
red balls : 6
yellow balls : 7
green balls : 2
total balls = 6 + 7 + 2 = 15
P(red ball) = 6 / 15 = 2/5
P(3 consecutive red balls with replacement),
= (2/5) x (2/5) x (2/5)
= 8/125
