Answer:

x + 1

y = 9

Step-by-step explanation:

In order to solve this question we need to represent "y "in terms of "x" in the first equation, and the plug in the "y" value in the first equation into the second one. Luckily for us in the first equation it already shows what "y" is equal to in terms of "x" (based on the first equation y = -x + 10). Now we just need to plug in the value that we got instead of "y" in the second equation, and so we get....

y = 7x + 2

(plug in the y value and get the following ….)

-x + 10 = 7x + 2

(now just solve the following equation)

-x + 10 + x = 7x + 2 + x

10 = 8x + 2

10 - 2 = 8x + 2 - 2

8 = 8x

8/8 = 8x/8

1 = x

Now that we know the value of "x", all we need to do now is substitute the value of "x" into any of the equations and we will get the value of "y". So we do the following.....

y =  7x + 2

y = 7(1) + 2

y = 7 + 2

y = 9

Which sequence of transformations maps pre-image ABC to
matrenka [14]

Triangle ABC was reflected over the y-axis and  then translated 2 units up and 2 units to the right

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point up, down, left or right. If a point A(x, y) is translated b units up and a units to the right, the new point is A'(x + a, y + b).

Reflection is the flipping of a figure. If a point A(x, y) is reflected along the y axis the new point is A'(-x, y).

Triangle ABC is at A(1, 2), B(4, 6) and C(7, 3). If it is reflected over the y-axis, the new point is A*(-1, 2), B*(-4, 6) and C*(-7, 3). If it is then translated 2 units up and 2 units to the right, the new image is:

A'(1, 4), B'(-2, 8) and C'(-5, 5)

Hence, Triangle ABC was reflected over the y-axis and  then translated 2 units up and 2 units to the right

If AD = 5x + 3, TD = x + 27, what is AD?
Eddi Din [679]

The question is incomplete, but if we assume that you mean AD = TD , we have :

AD = TD ===》 5x + 3 = x + 27

===》 4x = 24

===》 x = 6

_________________________________

AD = 5 × ( 6 ) + 3

AD = 30 + 3

AD = 33
