Find [g o f](x)=5x-5,g(x)=3x-2
wariber [46]

Answer:

→f(x) = 5x - 5 \\→g(x) = 3x - 2 \\ [gof](x) = g(f(x))  = 3(5x - 5) - 2 \\ [gof](x) = 15x - 15 - 2 = 15x - 17 \\  \boxed{[gof](x) = 15x - 17}✓

  • <u>[gof](x) = 15x - 17</u> is the right answer.

Compare the perimeter and area of the original figure to the perimeter and area of the reduced figure using the scale factor. A
Serggg [28]

Answer:

- The scale factor is one-half

- The perimeter of the model is the product of the scale factor and the perimeter of the original rectangle

-The area of the reduced figure is (1/2)^2 = 1/4 times the area of the original figure

Step-by-step explanation:

The ratio of the length of the original rectangle to that of the reduced rectangle is 6 to 3, or a factor of 1/2. The ratio of the width of the original rectangle to that of the reduced rectangle is 2 to 1, or, again, a factor of 1/2. So, because this ratio of 1/2 is constant, we know the total scale factor is 1/2, making B correct.

The perimeter of a rectangle is: P=2l+2w, where l is the length and w is the width. The perimeter of the reduced figure is: P = 2 * 3 + 2 * 1 = 6 + 2 = 8 units. The perimeter of the original figure is: P = 2 * 6 + 2 * 2 = 12 + 4 = 16 units.

Notice that 16 * (1/2) = 8, which means that the perimeter of the scale-factored, reduced rectangle is "the product of the scale factor (which is 1/2) and the perimeter of the original rectangle (which is 16)". So, C is correct.

The area of a rectangle is: A=lw, where l is the length and w is the width. The area of the reduced figure is: A = 3 * 1 = 3 units squared. The area of the original figure is: A = 6 * 2 = 12 units squared.

Notice that 12 * (1/4) = 3, which means that E is correct, but D is wrong.

Hope this helps!

Solve for x no work needed
wariber [46]

Answer:

\huge\boxed{82 \textdegree}

Step-by-step explanation:

We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:

31+x+(x-15) = 180

Let's solve for x.

Combine like terms:

31+2x-15=180

Add 15 to both sides:

31+2x=195

Subtract 31 from both sides:

2x=164

Divide both sides by 2:

x= 82

So x is 82°.

Hope this helped!
