Triangle abc, with vertices a(3, 0), b(2, 4), and c(4, 2), undergoes a transformation to form triangle a′b′c′, with vertices a′(3, 0), b′(2, -4), and c′(4, -2). the type of transformation that triangle abc undergoes is a . if triangle a′b′c′ undergoes a transformation to form triangle a″b″c″, with vertices a″(-3, 0), b″(-2, -4), and c″(-4, -2), then the type of transformation that triangle a′b′c′ undergoes is a .

according to egenuity the answer is

step-by-step explanation:

d. 344.22

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

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!
