Answer:

A 2-column table with 3 rows. Column 1 is labeled x with entries 14, 28, 42. Column 2 is labeled y with entries 2, 4, 6.

Step-by-step explanation:

Examining the response options:

A 2- compartment chart with 3 rows. Column 1 is designated x with records 1, 5, 6. compartment 2 is designated y with records 5, 20, 30.

No, as y = 25 not 20 and x = 5 .

A 2- compartment chart with 3 rows. Column 1 is identified x with approaches 48, 32, 16. compartment 2 is designated y with listings 4, 2, 1.

No, y =64 not 48 and x= 4.

A 2- compartment chart with 3 lines. compartment 1 is designated x with records 0, 1, 3. compartment 2 is designated y with records 90, 70, 25.

No, y= 25+3*45= 160 not 90 and x = 3.

A 2- compartment chart with 3 lines. compartment 1 is designated x with records 42, 28, 14. compartment 2 is designated y with records 2, 4, 6.

Yes, as 2*7 = 14, 4*7= 28, 6*7= 42.

Someone please help with this question please

Step-by-step explanation:

Since Angle DAE = Angle BCE, lines AD amd BC are parallel (by Z-angles).

This means that Angle ADE = Angle CBE (by Z-angles).

We have 2 congruent angles and 1 congruent side (AD = BC, given).

By ASA congruence, triangles AED and CEB are congruent.

Determine the reveune for selling 500 helmets

Tasya [4]

Answer:

x is the price the helmets were sold at.

y is the business expenses.

r is the revenue.

500x - y = r

Step-by-step explanation:

500x - y = r

We multiply x, the price that the helmets were sold at. Then we subtract y, which is the business expenses. After this, we get r, our revenue.

You are in charge of the Annual Powder Puff football game. You designed a t-shirt to sell during the event. A company charges $7

vekshin1

We're looking for C(h), where h is the hundreds of shirts. The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500. Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect. I'll leave it to you to evaluate C(5).

Please Help me someone! I dont even know where to start.<br> Solve for X

professor190 [17]

So hmm notice the picture below

running a segment from the right-angle perpendicular to the opposite side, gives three similar triangles, one small, a medium and a large one

now, using proportions, you can simply $\bf \textit{using proportions}
\\\\\\
\cfrac{large}{small}\qquad \cfrac{10}{6}=\cfrac{x}{10}$

and solve for "x"

Match the reasons with the statements given in the proof. Note that the figure may not be drawn to scale.

Yuki888 [10]

Answer:

$\begin{array}{lll}&\text{Statement}&\text{Reason}\\1.&WX>XY&\text{Given}\\2.&\angle 3>\angle 4&\text{angle opposite longer side is larger angle}\\3.&\angle 1=\angle 3+\angle 2&\text{exterior angle is equal to the sum of remote interior angles}\\4.&\angle 1>\angle 3&\text{If a=b+c and } c>0, \text{then } a>b\\5.&\angle 1>\angle 4&\text{transitive property}\end{array}$

Step-by-step explanation:

1. Given WX>XY.

2. Then angle 3 has larger measure than angle 4, because angle opposite longer side is larger angle. This means that

$\angle 3>\angle 4.$

3. Consider exterior angle 1. By the exterior angle theorem, the measure of the exterior angle is equal to the sum of the measures of remote interior angles. Then

$\angle 1=\angle 3+\angle 2.$

4. Note that angle 2 has positive measure and then

$\angle 1>\angle 3.$

5. Since $\angle 1>\angle 3$ and $\angle 3>\angle 4,$ by the transitive property,

$\angle 1>\angle 4.$
