$\left\{\begin{array}{ccc}y=3x-4\\y=-2x+1\end{array}\right\\\\y=3x-4\\for\ x=0\to y=3(0)-4=-4\to(0;-4)\\for\ x=2\to y=3(2)-4=2\to(2;\ 2)\\\\y=-2x+1\\for\ x=0\to y=-2(0)+1=1\to(0;\ 1)\\for\ x=2\to y=-2(2)+1=-3\to(2;\ -3)$

Look at the picture.

Answer: x = 1; y = -1 → (1; -1)

Change in y over change in x is key

(4-1)/(5-6)=3/-1
13. -3

(9-4)/(2-0)=5/2
14. 5/2

(1-(-2))/(-6-4)=3/-10
15. -3/10

Leo is purchasing a bike that is on sale for 30% off. He knows the function that represents the sale price of his bike is c(p) =

Umnica [9.8K]

Answer:

f[c(p)] = 0.784p

Step-by-step explanation:

sales discount = 30%

sales tax = 12%

c(p) = 0.7p where p is the original price

f(c) = 1.12c where c is the sales price of the bike.

f[c(p)] = 1.12(0.7p)

f[c(p)] = 0.784p Last option.

Assume: p = 100

c(100) = 0.7(100) = 70

f(70) = 1.12(70) = 78.4

f[70(100)] = 0.784(100) = 78.4

Carson has $450 in his bank account and deposits $70 per month out of his babysitting money. Construct a linear function that mo

Anton [14]

Answer:

$y=450+70x$

Step-by-step explanation:

Let the number of months = x

It is given that,

Carson deposits $70 each month and has $450 in his bank account.

So, the initial deposit is $450 and monthly deposit is 40x.

Let Carson's bank balance = y (in dollars).

Thus, the linear function representing the bank balance is,

$y=450+70x$
