Step-by-step explanation:
y -4x = -1
y = 4x -1
then y = Mx + b
m = 4
b = -1
Answer:
a=7, b=14
Step-by-step explanation:
a. 2/6=x/21
cross multiply=
2×21=x×6
then solve
42=6x
divide both sides by 6
x=42/6=<u>7</u>
b. 150/84=25/x
cross multiply=
84×25=150×x
then solve
2100=150x
divide both sides by 150
x=2100/150=<u>1</u><u>4</u>
<u> </u><u> </u><u> </u><u> </u><u>H</u><u>O</u><u>P</u><u>E</u><u> </u><u>T</u><u>H</u><u>I</u><u>S</u><u> </u><u>H</u><u>E</u><u>L</u><u>P</u><u>S</u><u>.</u><u> </u><u> </u><u> </u>
108+621=729
So then 729-100=629
Therefore your answer is 629
Answer:
(1.5, -13.5)
Step-by-step explanation:
Midpoint Formula: 
Simply plug in our coordinates into the formula:
x = (17 - 14)/2
x = 3/2
y = (-11 - 16)/2
y = -27/2
The numbers are 15,18
They add to 33 and a difference of 3
