Answer:
y = -1/3x + 12/5
Step-by-step explanation:
Answer:
y=25x+7
Step-by-step explanation:
The equation will be in the form of y=mx+c where m is gradient/slope and c is constant,
normally referred as y intercept.
Slope is given by dividing change in y by change in x
Slope=(57-32)/(2-1)=25
Therefore slope is 25
For the first term
32=25(1)+c
C=32-25=7
Therefore, the general equation will be y=25x+7
Answer:
$377,358.49
Step-by-step explanation:
Let, the actual sales = $X
Given total sales amount including 6% of sales tax = $400,000
Therefore, (X+6% of X)= $400,000
⇒(X+X·6÷100)= $400,000
⇒(X+0.06X)= $400,000
⇒ 1.06X= $400,000
∴ X= $400,000÷ 1.06 = $ 377,358.49
Hence, the actual sales = $ 377,358.49
Answer:
Triangle = 5x - 8
Square = 4x + 8
Step-by-step explanation:
Triangle = 2x + 2x + x - 8
= 5x - 8
Square = (x + 2) x 4
= 4x + 8

Step-by-step explanation:
x = number of visits
y = number of earned points
the equation for the situation is (remember the 20 points starting balance) :
y = 5.5 × x + 20
and the question is now actually after how many visits she reached 75 earned points.
therefore,
75 = 5.5 × x + 20
55 = 5.5 × x
x = 55/5.5 = 10
she gets a free movie ticket after 10 visits.
