The values of x that make f(x)=0 are the values of x that make its factors zero.
x+8 = 0
x = -8
x-4 = 0
x = 4
The appropriate choice is
A. (-8, 0) and (4, 0)
Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
Answer:
x = 48
Step-by-step explanation:
Given a secant and a tangent from an external point to the circle, then
the product of the external part and the entire secant is equal to the square of the measure of the tangent , that is
2(2 + x) = 10² = 100 ( divide both sides by 2 )
2 + x = 50 ( subtract 2 from both sides )
x = 48
Answer: 
Step-by-step explanation:
We have the following polynomial:
This is a polynomial of the form 
. Following this rule to expand it, we have:
Applying common factor 
:
Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:
Answer:
250, 1250
Step-by-step explanation:
Since 10/2 = 50/ 10 = 5, the common ratio = 5 So the next term in the sequence is found by multiplying the last term by 5.
Therefore, 50 x 5 = 250 and 250 x 5 = 1250. So, the next two terms in your sequence are 250 and 1250
