Hello!
First you to do 65 * 0.20
0.20 is 20% as a decimal
65 * 0.20 = 13
$13 is how much John saves.
To find out how much the skateboard cost you subtract how much he saved by the cost of the skateboard
65 - 13 = 52
The skateboard cost $52
Hope this helps!
Answer:
f(x)=-4(x+3/4)^2-6x-1
Step-by-step explanation:
Answer:
72.73
Step-by-step explanation:
First, find the x-intercept.
The x-intercept will be at the point (x, 0) where x is any real number. If we substitute the x-coordinate and the y-coordinate for the x and y variables in the equation, we can solve for x.
5y + 3x = 15
5(0) + 3x = 15
3x + 15
x = 5
We found the x-intercept now find the y-intercept with the same process.
The y-intercept will be at the point (0, y) where y is any real number.
5y + 3x = 15
5y + 3(0) = 15
5y = 15
y = 3
So, the x-intercept is (5, 0) and the y-intercept is (0, 3)
You wrote it there yourself, at the beginning of your question.
You wrote E = I x R
Divide each side by ' I ' : E / I = R
That's what you're asking for. ^
