What is 18x-9(x-1)=5(3x+3)

Mathematics
1 answer:
Alexandra [31]4 years ago
3 0

Answer:

-4

Step-by-step explanation:

18x - 9(x - 1) = 5(3x + 3)

Step 1: Distribute

18x - 9x - 9 = 15x + 15

Step 2: Combine like terms

9x - 9 = 15x + 15

Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side

9x - 9 = 15x + 15

-9x        -9x

-9 = 6x + 15

-15         -15

-24 = 6x

/6      /6

-4 = x

3 feet by 5 feet is the original figure.

We can obviously say that the triangle falls into the Not Similar - Different Shape category since it is a triangle, and we were given a rectangle

We can obviously say that the parallelogram (right next to the triangle) falls into the Not Similar - Different Shape category since it is a parallelogram, and we were given a rectangle

The 3 feet by 4 feet falls into the category of Not similar - Different ratio of Side Lengths because  the original was 3 feet by 4 feet. And so then one side remained the same while the other went decreased, so they are not in a ratio.

The 12 feet by 15 feet falls into the category of Not similar - Different ratio of Side Lengths because 12 feet by 15 feet can be simplified in a ratio of 4 to 5 while the original is 3 to 5

The 6 feet by 10 feet falls into the category of Similar because  6 feet by 10 feet can be simplified in a ratio of 3 to 5 and the original is 3 to 5.

The 3 feet by 5 feet falls into the category of Similar because  it is the same exact figure just rotated!

Answer:

Option A)   Inside the circle

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The radius is equal to the distance from the center to any point on the circle

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

A(-5,-8),M(-1,-3)

substitute the values

r=\sqrt{(-3+8)^{2}+(-1+5)^{2}}

r=\sqrt{(5)^{2}+(4)^{2}}

r=\sqrt{41}\ units

step 2

Find the distance from the center to point V

we know that

If the distance from the center to point V is equal to the radius, then the point V lie on the circle

If the distance from the center to point V is less than the radius, then the point V lie inside the circle

If the distance from the center to point V is greater than the radius, then the point V lie outside the circle

we have

A(-5,-8),V(-11,-6)

substitute in the formula

d=\sqrt{(-6+8)^{2}+(-11+5)^{2}}

d=\sqrt{(2)^{2}+(-6)^{2}}

d=\sqrt{40}\ units

so

\sqrt{40}\ units< \sqrt{41}\ units

The distance from the center to point V is less than the radius

therefore

The point V lie inside the circle

Wouldn't it be
