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!!

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 )

Solve the following equation by graphing each line below.
a) 2x+3=-x+9
b) Where do the two lines intersect? Write your answere in the form (x,y)
Answer:
x=2
Step-by-step explanation:
2x+x+3=9
2x+x=9-3
3x=9-3
3x=6
x=2
Answer:
a) 2x + 3 = -x + 9
or, 3x = 6
# x = 2 since there is no y in the equation the value of y could be 0.
b) it intersects at ( 2, 0 )

Answer:
x= 7/6
Step-by-step explanation:
collect the like terms. so in this problem -4x and -8x are like terms.
you'll then have -12x = -8 - 6
calculate the difference of -8 and 6
you'll then have -12x = -14
you then divide the both sides by -12
getting the solution: x= 7/6

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
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
