Answer:

I geuss because the scale factor is 2 that the resulting triangle will be almost twice the size. Because in a dilation you multiply it. If you dont know how to dilate a triangle with a compass I would suggest looking for a video online. But I know for the part that says "Is the image of ABC similar to the original triangle" the answer would be yes it is similar because you are just dilating the triangle not changing its orientation. I hope this helps! Good luck!

Answer:

Slope = 3

Step-by-step explanation:

Calculate using slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

[tex](x1, y1) = (4, 9)[/tex] and [tex](x2, y2) = (7, 18)[/tex]

[tex]m = \frac{18 - 9}{7 - 4} = \frac{9}{3} = 3[/tex]

Answer: {±2√3}

Step-by-step explanation: Since only one term contains an x in this problem, we can simply get the x by itself by dividing both sides by 5 and then square rooting both sides to get x = ±√12

Remember to use plus or minus when

square rooting both sides of an equation.

Now, √12 breaks down to 2√3 so our

final answer is {±2√3}.

If the variable only appears in one of the terms in the equation,

you can solve it by simply isolating the variable.

Answer:

(x + 9)(x - 5)

Step-by-step explanation:

x^2 + 4x - 45

factorising by using middle term break method

=x^2 + (9 - 5)x - 45

=x^2 + 9x - 5x - 45

=x(x + 9) - 5(x + 9)

=(x + 9)(x - 5)

Answer:

Answer:

y=6x+28

Step-by-step explanation:

Using the given variables, find the equation of the line using y=mx+b

In this equation, m=slope, which means m=6

So now we have y=6x+b. We need to find the b value.

Plug in the point (-4,4) into the equation and solve for b like so:

y=6x+b

4=6(-4)+b

28=b

Now, plug in your m value and b value into y=mx+b to get your answer of y=6x+28

Step-by-step explanation:

The domain of the function graphed below is set of all numbers less than 7 or x<7.

The domain of a function f(x) is the set of points(representing independent variable x) to define the function.

In the shown graph of the function,

The given function is defined everywhere except 7 and greater than 7.

So, the domain of the function is x<7.

Hence, the  domain of the function graphed below is set of all numbers less than 7 or x<7.

Answer:

Sum of the areas of two  shaded regions = 100 unit² (Approx.)

Step-by-step explanation:

Given:

Radius of circle = 6 units

Angle of one unshaded area = 160'

Find:

Sum of the areas of two  shaded regions

Computation:

Angle of one shaded area = 180' - 160'

Angle of one unshaded area = 20'

Sum of the areas of two  shaded regions = 2[θ/360][πr²]

Sum of the areas of two  shaded regions = 2[160/360][(3.14)(6)²]

Sum of the areas of two  shaded regions = 2[160/360][(3.14)(36)]

Sum of the areas of two  shaded regions = 2[160/360][(3.14)(36)]

Sum of the areas of two  shaded regions = [0.888][113.04]

Sum of the areas of two  shaded regions = 100.46

Sum of the areas of two  shaded regions = 100 unit² (Approx.)
