B: -8
8 times 1 = 8, and since there is a negative in front of the 1 when you are multiplying, it should be -8/
7. = 29/9 0.6 terminating
8. = 301/20 0.75 terminating
Answer:
x = 5
Step-by-step explanation:
Given
x =
( square both sides )
x² = 3x + 10 ( subtract 3x + 10 from both sides )
x² - 3x - 10 = 0 ← in standard form
(x - 5)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 2 = 0 ⇒ x = - 2
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = 5
right side =
=
= 5 = left side ← solution
x = - 2
right side =
=
= 2 ≠ - 2 ← not a solution
Thus x = 5 is the solution to the equation
Answer:
D
Step-by-step explanation:
We can see in the graph f(x) that the x intercept is
.
In the table of g(x), we can see that the x intercept is
.
Since
, the x intercept of the graph f(x) is greater than the x intercept of graph g(x).
