HELP IM DOING THE TEST
enyata [817]

Answer:

The slope of the line that contains the points (-1, 2) and (4, 3) is:

  • Slope = m =  1 / 5        

Step-by-step explanation:

Given the points

  • (-1, 2)
  • (4, 3)

Finding the slope between (-1, 2) and (4, 3)

\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:3\right)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [3 - 2] / [4 - (-1)]

               = 1 / 5                  

Thus, the slope of the line that contains the points (-1, 2) and (4, 3) is:

  • Slope = m =  1 / 5

Which value of d is a solution to equation 2.2d + 5.4= 12
ryzh [129]

Hello!

<em><u>Answer:</u></em>

<em><u>d=3</u></em>

<em><u>*The answer must have a positive sign.*</u></em>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you multiply by 10 from both sides of an equation.

2.2d*10+5.4*10=12*10

Then, you had to refine the problem down.

22d+54=120

Next, you subtract by 54 from both sides of an equation.

22d+54-54=120-54

Simplify.

22d=66

You can also divide by 22 from both sides of an equation.

\frac{22d}{22}=\frac{66}{22}

And finally, simplify and solve. You can also divide by the numbers.

66/22=3

Final answer: → d=3

Hope this helps!

Thanks!

-Charlie

Have a great day!

:)

A red candle is 8 inches tall and burns at a rate of 7/10 inch per hour.
ira [324]

Answer:

  11 3/7 hours

Step-by-step explanation:

The shorter candle burns faster, so the candles will not be the same height (0) until the taller candle burns completely. At 0.7 in/h, that will take ...

  (8 in)/(0.7 in/h) = 80/7 h = 11 3/7 h
