Two transformation are performed on a figure in the coordinates plane. the first transformation is a translation 8 units to the left. which sedona transformation will result in a image that is similar to, but not congruent to, the original figure?

a. a clockwise rotation of 90 degrees about the center
b. a clockwise rotation of 180 degrees about the center
c. a dilation by a scale factor of 1 with the origin as the center of a dilation
d. a dilation by a scale factor of 1/2 with the origin as the center of dilation

20

step-by-step explanation:

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!
