Answer:

4x-5y=2, 24x-47y=22

Step-by-step explanation:

I mean I would write out all the steps for the answers if I wasn't feeling lazy.

4x-5y=2

10x-21y=10

x=-\frac{4}{17},y=-\frac{10}{17}

Here you can have the answers:

4x-5y=2

3x-y=4

x=\frac{18}{11} , y=\frac{10}{11}

4x-5y=2

24x-47y=22

x=-\frac{4}{17},y=-\frac{10}{17}

4x-5y=2

10x+3y=15

x=\frac{81}{62},y=\frac{20}{31}

4x-5y=2

14x+26y=12

x=\frac{56}{87},y=\frac{10}{87}

It seems that 4x-5y=2, 24x-47y=22 is the correct answer.

Find g[h(x)] if g(x)=x^2 and h(x)=x+3
svetlana [45]

Answer:

g(h(x)) = [x + 3]^2 or x^2 + 6x + 9

Step-by-step explanation:

g[h(x)] signifies that h(x) is the input to g(x).

Writing out g(x) = x^2 and replacing "x" with [x + 3], we get:

g(h(x)) = [x + 3]^2 or x^2 + 6x + 9

The diagram below shows a student using a clinometer to measure the height of a flagpole. When the student stands 40 feet away f
AVprozaik [17]
The correct answer is the flagpole is <span>33 feet high</span>.

Explanation:
Please refer to the attached picture.

We know:
CD = 40 feet
AC = 5 feet
∠BDC = α = 35°

Using trigonometry, we know that the definition of the tangent of an angle is the ratio between the opposite side and the adjacent side, therefore:
tan α = BC / CD

Solving for BC:
BC = CD · <span>tan α
      = 40 </span>· tan (35)
      = 28 feet

In order to find the height of the flagpole, we need to add the distance of the clinometer from the ground:
AB = BC + AC
      = 28 + 5
      = 33

Hence, the flagpole is 33 feet high.
