PLEASE HELP!!!<br> Question is above^
julsineya [31]

Answer:

C

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 9, 2) and (x₂, y₂ ) = (- 4, 2)

d = \sqrt{(-4+9)^2+(2-2)^2}

  = \sqrt{5^2+0^2} = \sqrt{25} = 5 → C

Given that h(x) = -3x - 7, what is h(-4)?
iris [78.8K]

Answer:

x=−3x−7whatish(−4)

Step 1: Flip the equation.

28ah2istw−3x=x

Step 2: Add 3x to both sides.

28ah2istw−3x+3x=x+3x

28ah2istw=4x

Step 3: Divide both sides by 28h^2istw.

28ah2istw

28h2istw

=

4x

28h2istw

Phone chargers in a store are priced $19, $18, $15, $17, $19, $12, $19, and $15.
fredd [130]

The display that would best show the measures of variation of the given prices is; B: Box and Whisker Plot

<h3>What is the importance of Box and Whisker Plot?</h3>

We are given the prices of Phone chargers in a store as;

$19, $18, $15, $17, $19, $12, $19, and $15.

Now, since we want to determine the display that would best show the measures of variation, the best display would be a box and whisker plot. This is because Box and Whisker plots are a great chart to use when showing the distribution of data points across a selected measure. These  box and whisker plots display ranges within variables measured.
