need help with this algebra problem ALG 2A
Answer:
If you are trying to simplify the expression, the answer is -14x^2+8x-37
Step-by-step explanation:
First, keep removing the parentheses.
(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)
Next, try expanding the expression.
3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6
3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6
3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2
Finally, simplify the expression.
-14x^2 8x-37
I hope this helped to answer your question.
On a trip, Miguel drives at an average speed of 55 miles per hour. After 2 hours, the odometer on his car reads 4583. Write an equation to represent the reading on the odometer m after h hours.
Answer:
[tex]m=4473-55h[/tex]
Step-by-step explanation:
Step one
Given data
speed= 55 miles per hour
time taken = 2 hours
Hence the distance covered is
from v=d/t
distance= velocity * time
distance= 55*2
distance= 110 miles
this means that the initial reading of the odometer is
=4583-110
=4473 miles
after h hours the distance covered will be
distance = 55*h
distance= 55h
the reading of the odometer m is
m= initial reading-distance
Hence the reading of the odometer m is expressed as
[tex]m=4473-55h[/tex]
Answer:
Correct
m=55h+4473
Step-by-step explanation:
i got it right :-)

find the midpoint of joining 4 - 5 and 8 - 3
Answer:
(6, - 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (8, - 3) , then
midpoint = ([tex]\frac{4+8}{2}[/tex], [tex]\frac{-5-3}{2}[/tex] ) = ([tex]\frac{12}{2}[/tex], [tex]\frac{-8}{2}[/tex] ) = (6, - 4 )

Find the slope of the following graph.
yaxis
(2.2)
(1.2)
Answer:
Y = 2
Step-by-step explanation:
Use the formula below to find the slope. Plug 0 in for X to find the y intercept. In this case there is no slope. Make sure next time to use commas , instead of periods . when writing coordinates.

Which expression is equivalent to 8x - 12y + 32?
A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)
Answer:
It's the third
16(0.5x - 0.75y +2)
Step-by-step explanation:
You just divide everything by 16
8x/16= 1/2x=0.5x
-12y/16 = -3/4x=-0.75x
32/16=2
Hope this helps, have an amazing day ^_^
I’m doing a percent equation problem and the question is blank % of $50 =$35 help me plzzzz
Answer:
70
Step-by-step explanation:
blank % of $50 =$35
Let us take x in place of blank.
x % of $50 =$35
x/100 * 50 = 35
x/2 = 35
x = 35*2
x = 70
Therefore, 70% of $50 =$35
What is the y-intercept of this line: y=5x
Answer:
0 is the y-intercept
Step-by-step explanation:
Sorry forgot to post the problem here it is
Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55
solving systems equations: substitution
y=6x+5
y=4x+5
Answer:
y=6x+5 →equation 1
y=4x+5 → equation 2
you can either substitute equation 1 in 2 or equation 2 in 1
substituting equation 1 in 2,
y = 4x + 5
6x + 5 = 4x + 5
6x - 4x = 5 - 5
2x = 0
x = 0/2
x = 0
substituting x = 0 in equation 1, (to get y)
y = 6x + 5
y = 6(0) + 5
y = 0 + 5
y = 5
hope it helps you!!
