Answer:
From the graph, the slope is -4/5 and the y-intercept is 4 so the slope-intercept equation is y = -4/5x + 4. To convert to standard form we'll do:
y = -4/5x + 4
5y = -4x + 20
4x + 5y = 20
4/5; 16/20; 24/30.
10/4; 20/8; 15/6
Answer:
See explanation below.
Step-by-step explanation:
First, obtain the percentage of sales tax for a sale. Say it is 5%.
Then, obtain the sale prices, for two items say they are: $25.00 and $15.00.
Add the amounts together to obtain the subtotal:
$25.00 + $15.00 = $40.00, is the subtotal.
Multiply the amount by the percentage:
$40.00 * 5% =
40 * .05 = $2.00, is the sales tax
Add the tax to the subtotal to obtain the total amount to pay:
$40.00 + $2.00 = $42.00, is the total amount to pay.
Hope this helps!! Have an Awesome Day!! :-)
Answer:
Step-by-step explanation:
Direct variation can be modeled by y = kx where k is the constant of variation!
So to solve for k all we need to do is substitute in the value for y and x that are given.
So according to the problem y = 24 when x = 6
24 = 6k
Divide both sides by 6
k = 4
So the constant of variation is 4
The direct variation equation would then be
y = 4x
