The answer to that is: X = 8.

40 divided by 5 = 8.

To check we can do 5 x 8 = 40.

X = 8

Well you want to isolate x so in order to undo multiplication, you divide the 5 on both side that way it cancels on the side with the x.

5x/5=40/5

next, simply dived 40 by 5 which is 8, x=8

WE has a midpoint at K. The coordinates of the midpoint K are (0,3) and the coordinates of W are (2,-1). Find the coordinates of

sergiy2304 [10]

Answer:

Coordinates of E is (-2,7)

Step-by-step explanation:

Midpoint = ((x1+x2)/2,(y1+y2)/2)

xK = (xW + xE)/2 => xE = 2xK - xW = 2(0) - 2 = -2

yK = (yW + yE)/2 => yE = 2yK - yW = 2(3) - (-1) = 7

Find the unit rate for each brand. Round to the nearest cent (hundredth).

Natasha_Volkova [10]

The unit rate of each of the brands are:

Brand A's unit rate = 37 cents per ounce.

Brand B's unit rate = 31 cents per ounce.

The unit rate of each brand is simply how much a brand of tomatoes will cost per ounce.

To find the unit rate of each brand, do the following:

Brand A's unit rate = 2.99/8 = $0.37 per ounce = 37 cents per ounce.

Brand B's unit rate = 4.99/16 = $0.31 per ounce = 31 cents per ounce.

I need help with my math

Ket [755]

Step 1: Pick any two points

The points are represented as (x1,y1), (x2,y2).

where x1= -4, y1= -8, x2= 0, y2= 4

Step 2: Write out the formula of the equation to use

$\frac{y-y_1}{x-x_1}=\text{ }\frac{y_2-y_1}{x_2-x_1}$

Step 3: Substituting the values and to get the equation

$\begin{gathered} \frac{y-(-8)_{}}{x-(-4)}=\text{ }\frac{4-(-8)}{0-(-4)} \\ \frac{y+8}{x+4}=\frac{4+8}{0+4} \\ \frac{y+8}{x+4}=\text{ }\frac{12}{4} \end{gathered}$ $\begin{gathered} \frac{y+8}{x+4}=\text{ 3} \\ \text{Cross multiply} \\ y+8=\text{ 3(x+4)} \\ y+8=\text{ 3x+12} \\ \text{Collect like terms} \\ y=\text{ 3x+12-8} \\ y=\text{ 3x + 4} \end{gathered}$

The equation that represents the graph is y= 3x+4.

Option A is the correct answer.
