Answer:
y=26.67
Step-by-step explanation:
The given equation is 0.75x+1.5y=40.
We need to show the result of substituting x=0 in above equation.
0.75x+1.5y=40
Put x = 0
0.75(0)+1.5y=40
0+1.5y=40
⇒ 1.5y=4
So, the value of y = 26.67 when x = 0.

Answer:
Step-by-step explanation:
First start by finding the values of the numbers being multiplied together.
5^-2 = 25
This equals a positive 25 because when ever you multiply a negative by a negative it always equals a positive number. -5 x -5 = 25
= 2
This is asking what x what x what equals eight. Remembering that the square root of 4 is 2. We can determine that since 4 x 2 = 8 the cube root of 8 is 2.
2 x 2 x 2 = 8 and 8 divided by 2 divided by 2 = 2
So now solve the equation we have now. 25 x 2 =?
25 x 2 = 50
And 50 is our answer.
