Answer:

Angle PQW is equal to 35 degrees

Step-by-step explanation:

Angle PQW = 36x - 1

Angle WQR = 134x

Angle PQR = 169 degrees

To find angle PQW, Set Angles PQR and WQR to PQW. The equation should look like this:

PQR - WQR = PQW

Substitute in the values

169 - 134x = 36x - 1

Now add 134x to both sides and add 1 to both sides.

170 = 170x

Now divide 170 from both sides

x = 1

Plug x into angle PQW

36(1) - 1 = 35

Which equation can pair with x + 2y = 5 to create an inconsistent system?

Charra [1.4K]

X + 2y = 5
x = 5 - 2y

2x + 4y = 3
2(5-2y) + 4y = 3
10 - 4y + 4y = 3
10 ≠ 3

5x + 2y = 3
5(5-2y) + 2y = 3
25 - 10y + 2y = 3
-8y = 3 - 25
-8y = -22
y = -22/-8
y = 2.75

6x + 12y = 30
6(5-2y) + 12y = 30
30 -12y + 12y = 30
30 = 30

3x + 4y = 8
3(5-2y) + 4y = 8
15 - 6y + 4y = 8
-2y = 8 - 15
-2y = -7
y = -7/-2
y = 3.5

An inconsistent system is a system of equation that has NO SOLUTIONS.

2x + 4y = 3 is the equation to be paired with x + 2y = 50 to create an inconsistent system.

The table of values below represents a linear function and shows Marco’s progress as he is pumping gas into his car. What is the

german

Answer:

3 gallons

Step-by-step explanation:

Given

Seconds Spent ----- Gallons of Gas

0 ---------------------------- 3

12 -------------------------- 5

24 ------------------------- 7

36 ------------------------- 9

48 ------------------------ 11

Required

Determine the output of the initial value

From the given parameters, we have that:

Gallon of gas is a function of time spent

This means:

The input is the time spent while the output is the gallon of gas

From the table above,

Initial Value = 0 seconds

The corresponding output of this is 3 gallons

Hence;

<em>Option C answers the question.</em>

The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20

Pepsi [2]

Answer: They can order from 0 to 449 bars, but no more.

Step-by-step explanation:

Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.

The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.

$0.40x+20$

To solve for x, subtract 20 on both sides, we get

$0.40x$

Divide 0.40 on both sides, we get

$x$ ......... → the number of bars that could be ordered, with the shipping costs and their spending requirements must less than 450.

Thus, they can order from 0 to 449 bars, but no more.

Prove the following with Euler's formula to write e^itheta and e^-itheta in terms of sine and cosine. Then subtract them.

kirill115 [55]

Euler's formula tells us that

$e^{i\theta}=\cos\theta+i\sin\theta$
$e^{-i\theta}=\cos\theta-i\sin\theta$

Suppose we subtract the two. This eliminates the cosine terms.

$e^{i\theta}-e^{-i\theta}=i\sin\theta-(-i\sin\theta)=2i\sin\theta$

Divide both sides by $2i$ and you're done.
