Answer: 4
Step-by-step explanation:
18-14=4
-6x + 7 = 8x + A
let x = -4
-6(-4) + 7 = 8(-4) + A
24 + 7 = -32 + A
31 + 32 = -32 + 32 + A
63 = 0 + A
A = 63
Answer:
y = 2x+3
Step-by-step explanation:
Sorry I'm probably too late since Quizziz doesn't wait unless you have the freeze timer thing.
y = mx+b
b is the y intercept. The y intercept (when x=0) is given in the table.
Now plug a coordinate in to solve for m.
My coordinates: (1,5)
5 = m + 3
Solve.
2 = m
m = 2
Note: never plug in the y intercept when looking for m.
You can also find the slope by (subtracting the y value of one coordinate from another y value of another coordinate)/(subtracting x value from the first y coordinate above from the x value from the second coordinate).
In this case, it'd be
m = (7-5)/(2-1)
m = 2/1
m = 2

Answer:
The rate at which water leaking is
gal/min.
Step-by-step explanation:
Given:
A large container holds 8 gallons of water.
After 56 minutes the container only has 1 gallon of water left.
Now, to find at what rate is the water leaking.
So, water leaked from the container = 8 gallons - 1 gallon = 7 gallons.
Time taken for leakage = 56 minutes.
<em>Now, to get the rate:</em>
![\frac{Gallons\ of\ water\ leaked}{Time\ taken\ for\ leakage}](https://tex.z-dn.net/?f=%5Cfrac%7BGallons%5C%20of%5C%20water%5C%20leaked%7D%7BTime%5C%20taken%5C%20for%5C%20leakage%7D)
![=\frac{7 gallons}{56 minutes}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%20gallons%7D%7B56%20minutes%7D)
![=\frac{1 gallon}{8 minutes}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%20gallon%7D%7B8%20minutes%7D)
The rate =
gal/min.
Therefore, the rate at which water is leaking is
gal/min.
