Answer:
B) x = +/- 17
Step-by-step explanation:
Answer:
y=(-2/3)x-9
Step-by-step explanation:
1) first put the equation in terms of y. You should get y=-(2/3)x-8.
2) parallel lines have the same slope so the slope for this line and the answer should be the same
3) using the form y=mx+b plug (-2/3) in as the slope or m
4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b
5) isolate the variable b and plug in your answer to the equation.
90 is 1/10 of the number 900.
The answer should be half (Can be written as .5 or 1/2) because there are only two types of twins, fraternal and identical. So therefore the probability is half
A computer desk, originally priced at $83, is now on sale for $78.85
originally priced at $83. After discount the price becomes $78.85
Discount amount = $83 - $78.85 = $4.15
Decrease rate = discount amount divide by original price
Decrease rate = 
Decrease rate = 0.05
To find percent of decrease we multiply by 100
0.05 * 100 = 5%
Decrease percentage = 5%
