Which of the following is a situation in which an equation cannot be solved using the quadratic formula? a. the right-hand side of the equation is zero. b. the coefficient of the x2-term is 1. c. one term of the polynomial has a degree of 3. d. the coefficient of the x-term is zero.

The quadratic formula is used to calculate the roots of equations with degree 2, ie. in the form y = ax² + bx + c, where a,b,c ∈ R (real numbers). So, the answer is C.

C.One term of the polynomial has a degree of 3.

Step-by-step explanation:

answer: the equation matches the regression

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
