Answer:
D
Step-by-step explanation:
If you are told that the slope is 2 that means that the equation cannot be A.
The slope is the number in front of the x. So far what you know is that
y = 2x + b
b is found from the given point.
- 7 = 2*(-8) + b Expand the right side
- 7 = - 16 + b Add 16 to both sides
- 7+16 = -16 + 16 + b
- 23 = b
answer y = 2x + 23
The answer is D

y = 2x - 81
Step-by-step explanation:
Fifteen and sixty two thousanths
The two angles are x and 9x/5
<h3 /><h3 />
Let the two angles we require be x and y.
<h3 /><h3>Ratio of both angles</h3>
We have that the ratio of both angles are x:y
Since both angles are in the ratio 5:9, we have that,
x:y = 5:9
⇒ x/y = 5/9
<h3 /><h3>Value of the other angle</h3>
So, we Make y subject of the formula
Multiplying both sides by y, we have
y × x/y = 5/9 × y
x = 5y/9
Multiplying both sides by 9, we have
9 × x = 5y/9 × 9
9x = 5y
Dividing both sides by 5, we have
9x/5 = 5y/5
y = 9x/5
So, the two angles are x and 9x/5
