Jason wanted to save his earnings for the newest version of iPad. He already owed his mother $3.00. If he earned $5.00 per week

and saved it all, the equation model for this situation would be f(x) = 5x – 3, where f(x) represents total amount saved, and x represents the number of weeks Jason has worked and saved his earnings. Which of the following statements represents the effects of the 5 and 3 on the graph of the linear parent function, f(x) = x?
A. The 5 decreases the rate of change causing the line to be less steep, and the 3 shifts the line down making the y-intercept (0, –3).

B. The 5 increases the rate of change causing the line to be steeper, and the 3 shifts the line up making the y-intercept (0, 3).

C. The 5 increases the rate of change causing the line to be steeper, and the 3 shifts the line down making the y-intercept (0, –3).

D. The 5 decreases the rate of change causing the line to be less steep, and the 3 shifts the line up making the y-intercept (0, 3).

A and b are positive integers. Find <img src="https://tex.z-dn.net/?f=-2a%2B3b" id="TexFormula1" title="-2a+3b" alt="-2a+3b" ali
lord [1]

A could be 2 while B could be 3, so -2a+3b turns into -4+9, which equals 5.

From what I know you can't really solve a a single equation with two-variables so it's just a matter of trial and error.

Just try plugging in a small number like 2 for a just to try it and you get 8b^2=72.

Divide everything by 8 to isolate b and you get that b^2=9.

Square root everything and you'll find that b=3. This is just one possible combination, I'm sure there are many more but this is obviously the one that was intended to be found.

Now that we know that a=2 and b=3 just plug them into the equation.

-2(2)+3(3)=?

-4+9=?

5

Sorry about having to use this ^ symbol, the equation maker is not working.

AfilCa [17]

Answer:Tara will need to buy more 8 2/3  pint of green paint.  

Step-by-step explanation:

Total amount of green paint Tara has =24 pints

Amount used to to paint a landscape =1/4 x 24= 6

Amount used To  painting a clover.= 5/8 x 24= 15

 Amount of paint remaining = Total paint - Amount used up in painting landscape and clover

= 24 - ( 15+ 6)

24-21

=3 pints left

Since she needs 11 2/3 pints of green paints , she will  need

11 2/3 - 3 = 8 2/3 .

Therefore she will need to buy more 8 2/3  pint of green paint.
