Number 12 says it's translated 2 units up (y-axis and y-coordinates) and 3 units right (x-axis and x-coordinates). The coordinates of A is (0,2) so add 3 to the x-coordinate and add 2 to the y-coordinate.

0 + 3 = 3 as x

2 + 2 = 4 as y

So the new coordinates of A' is L) (3,4)

Find the value of x and y. y=2x and 1.85x+3.7y=12.95

Len [333]

Answer:

x=1.4 y=2.8

Step-by-step explanation:

Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.

Simplifying by combining x: 9.25x=12.95

Then you just divide 12.95 by 9.25: x=1.4

Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.

B is the midpoint of AC, AB=5x and BC=2x+9 find AB,BC, and AC

german

Answer:

Step-by-step explanation:

5x = 2x + 9

3x = 9

x = 3

AB= 5(3)= 15

BC= 2(5) + 9= 10 + 9 = 19

AC= 15 + 19 = 34

A plant is already 52 centimeters tall, and it will grow one centimeter every month. Let H be the plant's health (in centimeters

Tasya [4]

Plant's height after 31 months:82 centimeters

<h3>How to find the height of the plant</h3>

The equation that can be used to find the height of the plant is given as

h = 52 centimeters + 1m

We have that the plant grows at 1 centimeter every month hence we have 1m in the equation.

Then the number of periods is m, Now we are to find the height in this period of time

h = 52 + 1*31

= 51 + 31

= 82

Hence the height after 31 months is given as 82 centimeters.
