Answer:

C. $\overleftrightarrow{EF}$

Step-by-step explanation:

We are asked to select the correct name for the given line.

We know that a line is a collection of points that continues forever in both directions.

A line is denoted by two sided arrow on top of the name of the line as:

$\overleftrightarrow{AB}$

We can see that points E and F lies on our given line, so the name of our line would be line EF.

$\overleftrightarrow{EF}$

Therefore, option C is the correct choice.

Chloe is painting on a stretched canvas that has an area of 108 square inches. The length of the canvas is 12 inches. The width

Stolb23 [73]

Answer: Width of canvas = 9 inches

Area left for painting after painting the border = 70 square inches.

Explanation :

Since we have given that

Area of painting = 108 square inches

Length of canvas = 12 inches

As we know that

$\text{Area of rectangle} = length\times breadth$

$108=12\times breadth\\\\\frac{108}{12}=breadth\\\\9=breadth$

So, breadth of canvas = 9 inches .

Now, Chloe paints a 1 inch wide blue border on the canvas.

$\text{So, remaining length left for painting after painting the border} = 9-1-1=9-2=7\text{ inches}$

$\text{ Remaining breadth left for painting after painting the border }= 12-1-1=12-2= 10\text{ inches}$

$\text{So , area of remaining portion }= length\times breadth \\\\ \text{ area of remaining portion }=7\times 10\\\\\text{ area of remaining portion }=70 \text{ square inches}$

Hence, remaining area = 70 square inches .

What is the solution to this problem (1,3)(5,k) m=2

Mazyrski [523]

Answer:

The solution of given problem is k = 11

Step-by-step explanation:

<u>slope of given two points formula:-</u>

slope m = $\frac{y_{2}- y_{1} }{x_{2}-x_{1} }$ .....(1)

Given points are (1,3) and (5,k)

given slope m = 2

now substituting m =2 and the given points are (1,3) and (5,k)

$2 = \frac{k-3}{5-1}$

on simplification we get solution

$k-3 = 8$

$k = 8 +3$

$k = 11$

Answer:

look below.

Step-by-step explanation:

When there's a letter, it represents a variable. You need to find the value (number) of this variable. This can be done by trying to isolate (put it by itself) the variable. So now, here is how to do it:

1) -2j + 6 = 2j - 8

-2j - 2j = - 8 - 6

-4j/4 = -14/4

j = 14/4

j = 7/2

2) 4h + 6 = 2h - 8

4h - 2h = - 8 - 6

2h/2 = - 14/2

h = -7

3) 9w + 9 = 3w - 15

9w - 3w = - 15 - 9

6w/6 = -24/6

w = -4

4) 45 = -9(e + 8)

45 = -9e - 72

45 + 72 = -9e

117/-9 = e

e = -13

5) 35 = -7t

35/-7 = t

t = -5

6) 12k + 13 = 8k + 33

12k - 8k = 33 - 13

4k/4 = 20/4

k = 5
