Answer:

hi there!

the correct answer to this question is: C) y=12x+20

Step-by-step explanation:

you don't have to worry about the y-intercept just look at the slope

to find the slope you use delta y over delta x

which means for example: (80-56)/(5-3) and you get 12

Point A is located at (3,-6) and point A is located at (1-2). What is the scale factor?

Anuta_ua [19.1K]

Answer:

The scale factor is 3.

Step-by-step explanation:

Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).

Therefore, the distance OA is given by $\sqrt{(3 - 0)^{2} + (- 6 - 0)^{2}} = 3\sqrt{5}$ units.

Again, the coordinates of point A' are (1,-2).

Therefore, the distance OA' is given by $\sqrt{(1 - 0)^{2} + (- 2 - 0)^{2}} = \sqrt{5}$ units.

Hence, the scale factor is $\frac{OA}{OA'} = \frac{3\sqrt{5} }{\sqrt{5}} = 3$ . (Answer)

Someone please help me will give BRAILIEST!!!!!!!!!

RSB [31]

It's 26×10×10×10 because there are 26 possibilities (a-z) for the first letter and 10 possibilities (0-9) for each number. That makes the answer 26,000.

The perimeter of a triangle is 35 feet. One side of the triangle is five feet longer than the second side. The third side is thr

Vaselesa [24]

<u>Given</u>:

The perimeter of the triangle = 36 feet.

Let the three sides of the triangle be x, y and z.

The measurements of the sides of the triangle are given by

$x=5+y$ and $z=3+y$

We need to determine the length of the sides.

<u>Value of y:</u>

Let us determine the value of y using the perimeter formula.

$Perimeter =x+y+z$

Substituting the values, we get;

$35=5+y+y+3+y$

$35=8+3y$

$27=3y$

$9=y$

Thus, the value of y is 9 feet.

Hence, the length of the second side is 9 feet.

<u>Length of the sides:</u>

Length of the 1st side is given by

$x=5+y$

$x=5+9$

$x=14$

Thus, the length of the first side is 14 feet.

Length of the third side is given by

$z=3+y$

$z=3+9$

$z=12$

Thus, the length of the third side is 12 feet.

Therefore, the length of the sides of the triangle are 14 feet, 9 feet and 12 feet.

I need help ASAP!!!!!!!!! PLZZZ

frutty [35]

Answer:

b

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AB}{XY}$ = $\frac{BC}{YZ}$ , substitute values

$\frac{15}{10}$ = $\frac{21}{YZ}$ ( cross- multiply )

15YZ = 210 ( divide both sides by 15 )

YZ = 14 → b
