Equation of 2x+5y=-10

Algebra Examples

Add 5y to both sides of the equation. Divide each term by 2 and simplify. Divide each term in 2x=10+5y 2 x = 10 + 5 y by 2 2

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
