Answer:

6.5 weeks without parental help, 3.5 weeks with help from your parents.

Step-by-step explanation:

The Equation is:

Y = 20x

Y = Starting price for bikes

X = # of weeks

Therefore:

$130 = 20x

This can be simplified by solving for x

x = 130/20

x = 6.5 weeks

If your parents gave you $60 to help buy the bike the equation would be written as:

Y = 20x + 60

$130 = 20x + 60

Subtract 60 from both sides to get:

$70 = 20x

Solve for x

x = 70/20

x = 3.5 weeks

Answer:

There is no solution.

Rewrite -2x + y = -6 so it starts with y =...

y = 2x - 6

Substitute that in 2/3x - 1/3y = -2 gives:

2/3x - 1/3*(2x -6) = -2

2/3x - 2/3x + 2 = -2

0 + 2 = -2

This statement is not true, and that means there is no solution.

Answer:

D. y = –3x2

Step-by-step explanation:

Answer:

y = -3x^2

Step-by-step explanation:

A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.

Answer:

$\boxed{\bf x=7}$

$\boxed{\bf GH= 52}$

Step-by-step explanation:

In the line segment..

$\bf 7x+3+3x-5=9x+5$

Combine like terms.

$\bf 10x-2=9x+5$

Add -2 to both sides.

$\bf 10x-2+2=9x+5+2$

$\bf 10x=9x+7$

Subtract 9x from both sides.

$\bf 10x-9x=9x+7-9x$

$\boxed{\bf x=7}$

$\bf GH=7x+3$

$\bf 7(7)+3$

$\bf 49+3$

$\boxed{\bf 52}$
