Which equations are equivalent to Three-fourths + m = negative StartFraction 7 over 4 EndFraction? Select three options.

m = negative StartFraction 10 over 4 EndFraction

m = negative five-halves

Step-by-step explanation:

Given equation :

Which equations are equivalent to Three-fourths + m = negative StartFraction 7 over 4 EndFraction

3/4 + m = - 7/4

Subtracting 3/4 from both sides

3/4 + m - 3/4 = - 7/4 - 3/4

m = - 10/4

m = - 5/2

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
