Answer:
replace x with each of the value then solve for the value
Step-by-step explanation:
when raised to the power of a negative you do the inverse
2^-2 = 2^1/2
Answer:
7/20 is not equivalent to 1/3
Answer:
5y + 2y - 4x + 4x = -7 +14
7y = 7
y = 1
2(1) + 4x = 14
4x = 12
x = 3
Step-by-step explanation:
Using the process of elimination
Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.
When y is found, input it into the second equation to find x.
Answer:
240766 - 52731x + 840x^2 + 144x^3
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9
