Answer:
y = x+3
Step-by-step explanation:
First step is to find the slope
m = ( y2-y1)/(x2-x1)
= ( 7-9)/(4 - 6)
= -2 / -2
= 1
The we can put is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Putting in one of the points
9 = 1*6+b
Subtracting 6
9-6 = b
3=b
y = 1x+3
y = x+3
Answer:
y = 100 - 5x
Step-by-step explanation:
Total amount of gift card = $100
Amount spent per day = $5
Number of days = x days
Write an equation to show the amount left on the card after x days
y = 100 - 5x
Where,
y = amount left on the gift card
x = number of days
For example,
Assume x = 2 days
Amount left on the gift card, y
y = 100 - 5x
y = 100 - 5(2)
= 100 - 10
= 90
y =$90
Think of the three rectangles as a single large rectangle and find its area.
For the large rectangle made up of the three small rectangles:
Length = 8 cm + 15 cm + 17 cm = 40 cm
Width = 11 cm
area = length * width
area = 40 cm * 11 cm
area = 440 cm^2
-6a - 48 This answer should be correct
