I WILL MARK BRAINLIEST!!! 45 POINTS!!!! <br> Solve using substitution<br> y= -8x-6<br> y= -3x +4
Nuetrik [128]

Given :

y= -8x-6

y= -3x +4

By solving it, we get,

-8x-6 = -3x+4

=  > x =  - 2

Substituting the value of "x" in second given equation,

y =  - 3x + 4

=  > y =  - 3 \times ( - 2) + 4

By solving it, we get,

y = 10

Hence, the values are :-

x =  - 2 \\ y = 10

Suppose Tommy walks from his home at (0, 0) to the mall at (0, 7), and then walks to a movie theater at (5, 7). After leaving th
BaLLatris [955]
For this case, what we must do is find the distance between each ordered pair.
 For this, we use the formula of distance between points.
 We have then:
 d =  \sqrt{(x2-x1)^2+(y2-y1)^2}

 For (0, 0) and (0, 7):
 
d1=\sqrt{(0-0)^2+(7-0)^2}
 d1=\sqrt{(0)^2+(7)^2}
 d1=\sqrt{0+49}
 d1=\sqrt{49}
 d1=7

 For (0, 7) and (5, 7):
 
d2=\sqrt{(5-0)^2+(7-7)^2}
 d2=\sqrt{(5)^2+(0)^2}
 d2=\sqrt{25+0}
 d2=\sqrt{25}
 d2=5

 For (5, 7) and (5, 0):
 
d3=\sqrt{(5-5)^2+(7-0)^2}
 d3=\sqrt{(0)^2+(7)^2}
 d3=\sqrt{0+49}
 d3=\sqrt{49}
 d3=7

 before returning home the total distance is:
 d1 + d2 + d3 = 7 + 5 + 7&#10;&#10;d1 + d2 + d3 = 19

 Answer:
 
before returning home Tommy walks about 19 blocks

Ket [755]

Answer: 53.659 seconds

Step-by-step explanation:

Given: Vega swam her leg of the race in 27.98 seconds.

Janice swam her leg of the relay race in 25.679 seconds.

Then , their combined time for their part of the relay = (Time taken by Vega) + (Time taken by Janice)

= 27.98 seconds +25.679 seconds

= (27.98+25.679)  seconds

= 53.659 seconds

Hence, their combined time for their part of the relay =  53.659 seconds
