IJKL is a rectangle, so opposite sides have the same length:

• IJ = KL   ⇒   6y - 6 = 2x + 20

• JK = IL   ⇒   3x + 21 = 6y

Substitute the second equation into the first and solve for x :

6y - 6 = 2x + 20

(3x + 21) - 6 = 2x + 20

3x + 15 = 2x + 20

x = 5

Solve for y :

3x + 21 = 6y

15 + 21 = 6y

36 = 6y

y = 6

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
stira [4]
Slope: 7   given point: (1,8)

y = 7x + b          step 1 - plug in the slope in the formula
8 = 7(1) + b       step 2 - plug in the given point
8 = 7 + b           step 3 - simplify the expression
b = 1                 step 4 - solve for b
y = 7x + 1         step 5 - plug in b

formula: y = 7x + 1

AXYZ is in Quadrant 1. It is rotated 90° counterclockwise around the origin.
Ainat [17]

Answer:

Quad 1

Step-by-step explanation:

AXYZ is in the 2nd quad bc of the rotation, then goes back to 1st quad bc of reflection (y axis). After this, the translation doesn't affect the movement of quadrants.  A""X""Y""Z"' lands in quadrant 1.

Write an expression equivalent to (7x + 5) - (3x - 5)​
KiRa [710]

Answer:

= 2(2x + 5)

Step-by-step explanation:

Given that:

= (7x + 5) - (3x - 5)​

By simplifying

"-" sign before bracket will alter the inner signs

= 7x + 5 - 3x + 5

Adding like terms

= 4x + 10

By taking 2 common we get:

= 2(2x + 5)

i hope it will help you!
