Answer:

The equations (6x+42) degrees and (18x-12) degrees are congruent angles so to set up the equation, put both expressions on different sides of the equals sign. Use properties of equality to get x=4.5

Step-by-step explanation:

Your equation should be 6x+42=18x-12

Add the 12 to both sides to get 6x+54=18x

Move the 6x to the other side to get 54=12x

Then divide by 12 on both sides to get 4.5

Therefore, x=4.5.

Dont graph it for me (it auto graphs it)

igomit [66]

Answer:

$y\leq -x+22$

$y\geq -0.5x + 16$

(8,13)

8 nickels

13 dimes

Step-by-step explanation:

x = nickels

y = dimes

$x+y\leq 22$

$x+y\leq 22\\\\-x -x\\\\y\leq -x+22$

$0.05x+0.10y\geq 1.60\\\\-0.05x -0.05x\\\\0.10y\geq -0.05x+1.60\\\\/0.10 /0.10\\\\y\geq -0.5x + 16$

(8,13)

8 nickels

13 dimes

Check your answer:

$y\leq -x+22$

$y\geq -0.5x + 16$

$y\leq -x+22\\\\13\leq -8+22\\\\13\leq 14$

This statement is true

$y\geq -0.5x + 16\\13\geq -0.5(8)+16\\13\geq -4+16\\13\geq 12$

This statement is true

Hope this helps!

Decide whether quadrilateral JKLM is a rectangle, a rhombus, or a square. More than one answer may apply!

NARA [144]

Answer:

Square.

Step-by-step explanation:

given J(-4,2) || K(0,3) || L(1,-1) || M(-3,-2)

given below the visual answer.

you can find the distance of coordinate to coordinate:

Distance of JK

√(-4-0)² + (2-3)²

√17

Distance of KL

√(0-1)²+(3--1)²

√17

Distance of LM

√(1--3)²+(-1--2)²

√17

Distance of MJ

√(-3--4)²+(-2-2)²

√17

All sides are similar of √17 , so its a square.
