3 divided by 5 = 0.60000 is the answer
Answeri think e?
Step-by-step explanation:
We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
Expand
6 - 3x + 15 = 5x - 11
Simplify 6 - 3x + 15 to -3x + 21
-3x + 21 = 5x - 11
Add 3x to both sides
21 = 5x - 11 + 3x
Simplify 5x - 11 + 3x to 8x - 11
21 = 8x - 11
Add 11 to both sides
21 + 11 = 8x
Simplify 21 + 11 to 32
32 = 8x
Divide both sides by 8
32/8 = x
Simplify 32/8 to 4
4 = x
Switch sides
<u>x = 4</u>
