Answer:
(A) -7
Step-by-step explanation:
The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.
x^2 +2 = 6x +k . . . . . must be true at x=3
3^2 +2 = 6(3) +k . . . . substitute 3 for x
9 +2 -18 = k . . . . . . . . subtract 18
k = -7 . . . . . . . simplify
A = 10
Step by step
3+7=10
10+(-7)=3
Answer:
A
Step-by-step explanation:
combining 10² and 10² makes 10⁴.
combining 1.5 and 1 makes 2.5.
so you have 10⁴ x 2.5, which is the same as the part on the other side of the equals symbol, making the equation true. All the other equations are false.
