Answer:

-17s + 23

Step-by-step explanation:

- 3(s - 10) + 7( - 2s - 1)

- 3(s - 10) =  - 3s - 3 \times ( - 10)

- 3s + 30 + 7( - 2s - 1)

- 3s + 30 - 14s - 7

- 17s + 30 - 7

\boxed{\green{= - 17s + 23}}

Answer:

2nd option will be the answer (y=4x²+48x+146)

Step-by-step explanation:

y=4(x+6)²+2

y=4(x²+2*x*6+6²)+2 [(a+b)²=a²+2ab+b²]

y=4(x²+12x+36)+2

y=4(x²)+4(12x)+4(36)+2

y=4x²+48x+144+2

y=4x²+48x+146

Find the distance between each pair of parallel line<br>y=x-6 and y=x+8
myrzilka [38]
Both these lines are linear and have the same slope, just different y-intercepts. This means one line is shifted higher than the other. y=x+8 is 14 units higher than y=x-6. The answer to you question therefore is 14 units!

Find the distance CD rounded to the nearest tenth
motikmotik

Answer:

CD ≈ 15.0

Step-by-step explanation:

calculate CD using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = C (7, - 4) and (x₂, y₂ ) = D (- 8, - 5)

CD = \sqrt{(-8-7)^2+(-5-(-4))^2}

     = \sqrt{-15)^2+(-5+4)^2}

     = \sqrt{225+(-1)^2}

     = \sqrt{225+1}

     = \sqrt{226}

     ≈ 15.0 ( to the nearest tenth )

Answer:

slope=1/4

y-intercept=3

y=.25x+3

Step-by-step explanation:

slope=rise over run so

slope=1/4

y-intercept is the value of y where the line crosses the y axis..

y-intercept=3

In y=mx+b form m is slope and b is y-intercept so...

y=.25x+3
