Answer:
Kyle saves 40 percent
$50 is 100% of what he had
$20 would be 40%
50= 100
40= 80
30= 60
20= 40
10= 20
do what u will with that info I'm bad at wording things
Answer:
y = 3x+1
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= (13-4)/(4-1)
= 9/3
= 3
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 3x+b
Using a point from the table
10 = 3(3)+b
10 =9+b
10-9 =b
1=b
y = 3x+1
Step-by-step explanation:
3)
(2x-3)(2x+3)
2x(2x+3)-3(2x+3)
4x²+6x²-6x-9
8x²-6x-9
Answer:
x =
y = (0,26)
Step-by-step explanation:
First find the x intercept
To find the x intercept, substitute 0 for y and solve for x.

Rewrite the equation as 

Subtract 6 from 0.

Divide each term in
by 4.

Cancel the common factor of 4.

Simplify 

Subtract 5 from both sides of the equation.

To write
as a fraction with a common denominator, multiply by 
· 
Combine
and
.

Combine the numerators over the common denominator.

Simplify the numerator.

Move the negative in front of the fraction.

x = 
-----------------------------------------------------------------------------------------------------
Find the y-intercepts.
To find the y-intercept(s), substitute in 0 for x and solve for y.

Add 0 and 5.

Multiply 4 by 5.

Add 6 to both sides of the equation.

Add 20 and 6.

y = (0, 26)
