Answer:
A
Step-by-step explanation:
We need to find two numbers that have a sum of 5 and a product of 6. These numbers are 2 and 3 so x² + 5x + 6 factored is (x + 2)(x + 3). Since x + 2 is a factor the answer is A.
Answer:
xy = - 8
Step-by-step explanation:
note that
(x - y)² = x² + y² - 2xy , that is
6² = 20 - 2xy
36 = 20 - 2xy ( subtract 20 from both sides )
16 = - 2xy ( divide both sides by - 2 )
- 8 = xy
Let x represent Holly's score on 7th math quiz.
We have been given that the mean of Holly's first six math quiz scores was 75%. This means that the average on 1st 6 math quizzes is 75.
To find the total scores on 1st 6 math quizzes, we will multiply 75 by 6 that is 
.
We will use average formula to find test scores on 7th math quiz.
Let us solve for x.
Therefore, Molly's score on the 7th math quiz was 89.
Answer:
9/29 or about 31%
Step-by-step explanation:
6+3=9 6+3+7+16=29 so 9/29 (have a great time finishing the rest of your work) :)
Point of intersection using substitution (p, j) is (-1, 1).
Given
2p - 6j = -8----------(1)
4p + 12j = 8---------(2)
From equation 1, We can write
2p = -8 + 6j
p = (-8 + 6j)/2
p = -4 + 3j
By using substitution method, substitute p = -4 + 3j in equation 2
4p + 12j = 8
⇒ 4(-4 + 3j) + 12j =8
⇒ 4 × (-4) + 4 × 3j + 12j = 8
⇒ -16 + 12j +12j = 8
⇒ 24j = 8 +16
⇒ 24j = 24
⇒ j = 24/24
⇒ j = 1
then p = -4 +3j
p = -4 + 3(1)
p = -4 + 3
p = -1
Point of intersection (p, j) is (-1, 1).
