Answer:
x=6
Step-by-step explanation:
(x^2 – 3x - 10) = (x + 2)
Factor the term on the left
(x-5) (x+2) =x+2
Divide each side by x+2
x-5 = 1
Add 5 to each side
x-5+5 =1+5
x=6
The answer is 11 because 4+(-7) is -3 since adding a negative is like subtracting a positive and -3+14 is 11. Hope this helps!
Answer:
5 lbs
Step-by-step explanation:
1) x = lbs. of coffee at $7 per lb
2) (7)(x) + (4)(10) = (5)(x + 10)
3) 7x + 40 = 5x + 50
7x - 5x = 50 - 40
2x = 10
x = 5 (lbs. of coffee at $7 per lb.)
Answer:
Step-by-step explanation:
<em>Represent the two polynomials with f(x) and g(x)</em>
<em>The question requires that we assume values for f(x) and g(x) as long as the condition in the question is met;</em>
Let
To determine if the condition is met, we need to divide f(x) by g(x)
Factorize the numerator
Cross out 5x + 2
The result is referred to as quotient, Q
<em>Note that Q and g(x) have the same degree of 1</em>
