solving systems equations: substitution
y=6x+5
y=4x+5

Answers

6x + 5 = 4x + 5
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 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!!

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

find the midpoint of joining 4 - 5 and 8 - 3​

Answers

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 )

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.

Answers

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
