Answer:
(x-8) (x+7)
Step-by-step explanation:
x^2 -x-56
We want to factor this problem.
What two numbers multiply to negative 56 and add to -1
-8 *7 = -56
-8+7 = -1
We can use -8 and 7
(x-8) (x+7)
Check:
FOIL
first: x*x =x^2
outer: 7x
inner:-8x
last: -8*7 = -56
Add this together
x^2 +7x-8x -56 = x^2 -x-56
Add all the number together and divide the amount of number
-23+-15+-18+2+3=-51
-51/5=10.2
Answer:
slope form = y= 3/4x -7
point slope= y-(-3) = 3/4(x-3) or y-(-4)= 3/4(x-4)
Step-by-step explanation:
slope form = y= mx + b
y = 3/4x - 7
point-slope form = y - y1 = m(x - x1)
step 1. Substitute a convenient value of x into your equation and solve for y (You're doing this to get the point x1,y1). Let's choose x=3. Yes, you could choose x=4.
y= 3/4x - 7
if you choose x = 3
y=3/4(3) - 7
y = 4 -7
y = -3
(x1,y1) = (3,-3)
if you choose x = 4l
y= 3/4(4) - 7
y = 3 - 7
y = -4
(x1,y1)= (4, -4)
step 2. Substitute the point you found , (x1, y1) , into the point slope formula.
if you choose x=3
y-y1=m(x-x1)
y-(-3) = 3/4(x- 3)
if you choose x = 4
y- y1 = m(x-x1)
y - (-4) = 3/4(x-4)

Answer:
13.75
Step-by-step explanation:
First you know there are 5 students and 5 teachers, for each student it costs 6.25 and for every teacher it cost 1.50. So 5 teachers x 1.50= 7.5. 5 students x 1.25 =6.25. 7.5 +6.25= 13.75
