Answer: The answer is 45 because you do parenthesis first which is 13.5-4.5=9 then you multiply 9×5=45 therefore the answer is 45.
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
Given
x³ - 13x² - 30x ← factor out x from each term
= x(x² - 13x - 30) ← factor the quadratic
Consider the factors of the constant term (- 30) which sum to give the coefficient of the x- term (- 13)
The factors are - 15 and + 2, since
- 15 × 2 = - 30 and - 15 + 2 = - 13, thus
x² - 13x - 30 = (x + 2)(x - 15) and
x³ - 13x² - 30x = x(x + 2)(x - 15) → d
The answer is C. b=2.
I found the answer by first finding the slope. To find the slope i found the difference of the y values and divided that by the difference of the x values.
14-5/4-1
This simplifies down to:
9/3 which equals 3.
I then plugged this into the slope intercept form: y=mx+b to get y=3x+b
The next step would be to plug in the values of one of the points to solve for b. The point I choose was (1,5). By plugging this point into the equation i got 5=3(1)+b which simplifies to 5=3+b which means that b=2
