Let's plug in the variables one by one.

6g - 2h

plug in 5 for g and 4 for h

6(5) - 2(4)

multiply

30 - 8

subtract

→ 22

20g

plug in 2 for g

20(2)

multiply

40

2(g + 1)

plug in 10 for g

2(10 + 1)

add

2(11)

multiply

→ 22

4g + 5h

plug in 1 for g and 4 for h

4(1) + 5(4)

multiply

4 + 20

add

24

Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)

Answer: 6g-2h when g=5 and h=4

and 2(g+1) when g=10 .

Step-by-step explanation:

1) 6g-2h  

when g=5 and h=4, then we have

6(5)-2(4)=30-8=22

2) 20 g  when g=2, we have

20(2)=40 ≠22

3) 2(g+1) when g=10 , we have

2(10+1)=2(11)=22

4) 4g+5h  when g=1 and h=4, we have

4(1)+5(4)=4+20=21≠22

Hence, the required answer is : 6g-2h when g=5 and h=4

and 2(g+1) when g=10 .

The las answer is Center E and scale factor 1/4 pleaseee helpp
hoa [83]
<h3>Answer: D) center E, scale factor 1/4</h3>

======================================

Explanation:

Point E is the center of the dilation (we can think of this as the origin point). This is because point E is in the same exact location as point E'. This is a fixed point. The other points move.

To find the scale factor, divide E'F' over EF

scale factor = (E'F')/(EF)

scale factor = 2/8

scale factor = 1/4

Keep in mind that EF = EF'+F'F = 2+6 = 8.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating
natulia [17]

Answer:

V=25088π vu

Step-by-step explanation:

Because the curves are a function of "y" it is decided to take the axis of rotation as y

, according to the graph 1 the cutoff points of f(y)₁ and f(y)₂ are ±2

f(y)₁ = 7y²-28;  f(y)₂=28-7y²

y=0;   x=28-0 ⇒ x=28

x=0;   0 = 7y²-28 ⇒ 7y²=28 ⇒ y²= 28/7 =4 ⇒ y=√4 =±2

Knowing that the volume of a solid of revolution  V=πR²h, where R²=(r₁-r₂) and h=dy then:

dV=π(7y²-28-(28-7y²))²dy ⇒dV=π(7y²-28-28+7y²)²dy = 4π(7y²-28)²dy

dV=4π(49y⁴-392y²+784)dy integrating on both sides

∫dV=4π∫(49y⁴-392y²+784)dy ⇒ solving  ∫(49y⁴-392y²+784)dy

49∫y⁴dy-392∫y²dy+784∫dy =

V=4π( 49\frac{y^{5} }{5}-392\frac{y^{3}}{3}+784y ) evaluated -2≤y≤2, or 2(0≤y≤2), also

V=8\pi(49\frac{2^{5} }{5}-392\frac{2^{3} }{3}+784.2)  ⇒ V=25088π vu

Answer:

The Missing number is 7

Step-by-step explanation:

5+4=9

2+6=8

9+8=17

And if the equations are supposed to have the same answer then you add 7 to 10 and they both have the same answer.
