Step-by-step explanation:
I think this is correct pls tell me if this is wrong
Hope this helps
Fraction = 21/8
decimal = 2.625
mixed number form = 2 5/8

Start by writing a formula, where
is Brad's purchase price and
is the original price.

Subtract
from both sides.

Multiply both sides by
.

Answer:
b=9,a=12
Step-by-step explanation:
I solved by substitution:
b = 3/4a ---> plug this into the other equation
a + b = 21 is now a + 3/4a = 21
Reduce: 7/4a = 21
a = 12
Now solve for b:
b=3/4a is now b=3/4(12)
b=9
Answer:
so the equation is y=-2x-4
Step-by-step explanation:
sub the points in the equation to find the y-intercept
y=x(-2)+b
0=-2(-2)+b
0=4+b
0-4=b
-4=b
