Answer:
x - 3 =
square both sides to get rid of square root
x^2 -6x + 9 = 4x - 7 , but remember 4x - 7 can't be less than 0 since it was square roots can't be less than 0
simplify the equation
x^2 - 10x + 16= 0
x = 8, x= 2
but x cannot equal 2, because if we plug in 2, the square root will be negative,
so x can only equal 8
so B is correct.
I'm not the best at quadratics, so pls comment if something is wrong
First we will see how many quarts are in a gallon.
1 gallon = 4 quarts.
Now lets MULTIPLY to get our answer.
5 gallon = ? quarts
5 × 4 = 20
So, the cooler has 20 quarts or 5 gallons.
Hope I helped ya!!!!!!!
Answer:
the rate of change is 1/2
Step-by-step explanation:
The rate of change is described by the change in y over the change in x. I'm guessing you meant to put an x after 1/2. The equation you wrote is in y-intercept form, as it gives us the slope and y-intercept. Slope is the same as rate of change. In simple terms, the number beside x is the rate of change. 1/2
You probably right...whoops
Answer:
4%
Step-by-step explanation:
1. Convert the problem to an equation using the percentage formula: P% * X = Y.
2. P is 10%, X is 150, so the equation is 10% * 150 = Y.
3. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
