Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8
A=bh
A/h bh/h
A/h=b
The answer s b= a/h
Step-by-step explanation:
multiply the ratio by the second ratios second number
A toy company needs to profit at least $500 from selling cars and trucks. A car can make a profit $2 while the truck can $3 profit.
let x be the number of cars
let y be the number of truck
If 200 resources for the car per week, we have:
Profit = $2x + $3y
$500 = $2*200 + $3*y
$500 - $400 = $3y
100 = 3y
y =100/3 = 33.33
The number of trucks needs to produce per week is at least 34 pieces.
1,000 bows x 0.75 meters
= 750 meters
We know that Nicole is making 1,000 bows and that each bow requires 0.75 m of a piece of ribbon. Therefore, we can multiply the number of bows by the length needed to make each bow in order to determine the total meters of ribbon needed to make all the bows - it's like adding 0.75 meters a thousand times for each bow. When multiplying, you get a product of 750 meters.
