Answer:

x = 12

WN = 28

Step-by-step explanation:

SO = WN and SO = 2WI

3x - 8 = 2(x + 2)

3x - 8 = 2x + 4

3x - 2x = 4 + 8

x = 12 now replace x with 12 in the first equation given

3x - 8 = 3×12 - 8

36 - 8 = 28

Just plug the corresponding x value on the left of a,b,c, and d into the equation. If you don't understand the equation, it is asking you to multiply x by 3 and then subtract 2.

These are the answers:

-11, -5, 1, 4.

Good luck!

The question is: "Without actually graphing, describe how the graph of y = ( -2^(x+17) ) - 4.3 is related to the graph of y = 2^
Leokris [45]

Answer:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Step-by-step explanation:

When functions are transformed there are a few simple rules:


  • Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
  • Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
  • Multiplying the function by a number less than 1 compresses it towards the x-axis.
  • Multiplying the function by a number greater than 1 stretches it away from the x-axis.
  • Multiplying by a negative flips the graph.

The graph of (-2^{x+17}) -4.3 compares to 2^x in the following ways:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

A water tank is 1.2 m square and 1.35 m deep. It is half full of water.How many times
MrRa [10]

Answer:

Well, the tank's volume is 1.2 x 1.2 x 1.35 = 1.944 m³ = 1944 litres.

It is half-full, so it contains 1944 / 2 = 972 litres of water.

That is enough to fill 972 / 9 = 108 9-litre buckets.

Step-by-step explanation: h = height of water = 1.35 m/2 = 0.675 m    

A = area of tank = s² = (1.2 m) = 1.44 m²    

V = volume of water    

V = Ah = (1.44 m²)(0.675 m)

What equation defines a line through points (-2, 7) and (6, -9)
Tanya [424]

7 =  - 2k + b \\  - 9 = 6k + b \\  \\ 7 =  - 2k + b \\  9 =  - 6k  -  b \\  \\16 =  - 8k \\ k =  - 2

Now we can find b

7 =  - 2 \times ( - 2) + b \\ 7 = 4 + b \\ b = 3

Answer:

y =  - 2x + 3
