Answer:
d. y+8=2(x-4)
Step-by-step explanation:
There are 2 important parts to this question. First, understanding which slopes are perpendicular. The negative reciprocal of a number will be perpendicular to it. So, since the original slope is -1/2 the new slope should be 2.
Then, remember what the point-slope formula is. The point-slope formula is: 
. So if you plug in the point and slope the new equation looks like, 
. Then, simplify for the final answer of 
.
Answer:
C
Step-by-step explanation:
1)Non- zeros (1,2,3,....) are always significant.
2)Captive zeros are significant too( zeros between non- zeros ).
3)Trailing zeros (zeros at the end) aren't significant always unless if there is a decimal point.
Such this question we have decimal point so we count them
Answer:
x > 8
Step-by-step explanation:
Solve for x to find the solution.
10 - 4x < -22
Subtract 10 from both sides.
-4x < -32
Divide both sides by -4. Flip the sign when dividing by negative.
x > 8.
