Using the quadratic formula, which of the following is the solution to the quadratic equation x2 - 3x - 28 = 0? a. x = -7, -4 b. x = 7, 4 c. x = -7, 4 d. x = 7, -4

The answer is (x+7)(x-4)

hence, the solution should be C

x = [ -)-3)  +/- sqrt((-3)^2 - 4*1*-28) ] / 2

=  (3 + sqrt 121) / 2   and (3 - sqrt 121) / 2

= 3/2 + 11/2  and 3/2 - 11/

= (1.5 + 5.5)   and 1.5 - 5.5

Answer is 7, -4

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
