Answer:
- (x - 4)(x - 11)
Step-by-step explanation:
Given
- x² + 15x - 44 ← factor out - 1 from each term
= - 1 (x² - 15x + 44) ← factor the quadratic
Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)
The factors are - 4 and - 11 , since
- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus
x² - 15x + 44 = (x - 4)(x - 11) and
- x² + 15x - 44 = - (x - 4)(x - 11)

the endpoints of line GH are G(0,4) and H(-6,2). find the coordinates of the midpoint M
Answer: The point G is G(18,-9)
Step-by-step explanation:
Midpoint:
Write the formula for midpoint of the A(x_1,y_1) and B(x_2,y_2).
[(x_1+x_2)/2,(y_1+y_2)/2]
G(x,y), H(-2,9)
(8,0) =[(x+(-2))/2,(y+9)/2]
(x+(-2))/2 =8
(x+(-2))=16
x-2 =16
x =18
(y+9)/2=0
y+9=0
y=-9
The point G is G(18,-9)

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has. If each loaf requires 3 and four-fifths cups of flour, how many loaves can Josh bake? 3 loaves of bread 4 loaves of bread 50 loaves of bread 51 loaves of bread
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The number of loaves Josh can bake with 13 and one-third cups of flour is 4 loaves.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has.
13(1/3) can be written as,
= 13(1/3)
= 40/3
Each loaf requires 3 and four-fifths cups of flour.
This can be written as,
3(4/5) cups of flour = 1 loaf
19/5 cups of flour = 1 loaf
Multiply 5/19 on both sides.
1 cup of flour = 5/19 loaf
Multiply 40/3 on both sides.
40/3 cups of flour = 40/3 x 5/19 loaf
40/3 cups of flour = 3.5 loaf
This means we can make 4 loaves.
Thus,
The number of loaves Josh can bake with 13 and one-third cups of flour is 4 loaves.

Answer:
m=-2
Step-by-step explanation:
3(3m-4)-3m=2m-18+m
remove the parentheses and collect like terms
9m-12-3m=3m-18
collect the terms

Simon bought 5 albums for $37.50. Matt bought 8 albums for $58.00. How much less did Matt spend per album than Simon?
Answer:
.25
Step-by-step explanation:
37.50/5=7.5
58/8=7.25
7.5-7.25=.25
Answer:
260
Step-by-step explanation:
So first you need to multiply 5 and 37. and the is 5×37 equals 185. So now your gonna multiply 8 by 58 and that is 464. So now that you have those two numbers ( 185, 464 ) your gonna add how ever much you need to get 464. So the closest to get to 464 is gonna be 260 I'm pretty sure.

Annalise ended the week with $0. What number could you add to
$55.32 that would result in a sum of $0?
Answer:
-55.32
Step-by-step explanation:
55.32 + (-55.32) = 0I hope this helps!
Answer:
Well the number would have to be a negative number, because, no positive number can cause a smaller number adding a positive number will always cause a larger number.
So the answer is: $55.32+(-$55.32)
Adding the -55.32 causes it to even out meaning that u basically just added the debt of 55.32. This debt is causing an decrease in the amount of money she has. So really you are subtracting money

What is 3 y + 5 x = negative 15 written in slope-intercept form?
Answer:
The answer would be y=-5/3x-5!
Step-by-step explanation:
You want to make the equation to y=mx+b, so you have to make y by its self. Subtract 5x from both sides and you'll get 3y=-5x-15. Now divide 3 by both sides and you'll get y=-5/3x-5 which would be the answer!
Answer:
y=(-5/3)x-5
Step-by-step explanation:
so the slope intersect form is y=mx+b
3y+5x=-15
subtract 5x from both sides
3y= -5x-15
divide both sides by 3
y= (-5/3)x - 5

Answer: D 1 hour 56 minutes
Answer:
D. 1 hour 56 minutes
Step-by-step explanation:
Well, if you add 2 hours to 12:14, it would be 2:14, so you know it's less than 2 hours. B and D are the only choices that have 1 hour. So, if Aaron left at 2:10, you have to subtract 4 minutes from 2 hours. That would be 1 hour and 56 minutes Aaron spent at the mall.

Step-by-step explanation:
Answer:
x = 4x = -2Step-by-step explanation:
Solving for x
|2x-2|=61. 2x - 2 ≥ 0 ⇒ 2x ≥ 2 ⇒ x ≥ 1
2x - 2 = 62x = 8x = 42. 2x - 2 < 0 ⇒ 2x < 2 ⇒ x < 1
