What is the solution to the equation 5 x + 2 x = 24 − 4 ( x − 5 ) ?

1 answer:

5 0

5x + 2x = 24 − 4 (x−5)

5x + 2x = 24 + (−4)(x)+(−4)(−5)

5x + 2x = 24 + −4x +20

(5x +2x) =(−4x) +(24 +20)

7x= −4x + 44
+ 4x + 4x

11x/11 = 44/11

Answer : x = 4

Is P 90 degrees from the origin, Q 180 degrees from the origin, and R 270 degrees from the origin?

krek1111 [17]

Answer:

Step-by-step explanation:

(x,y)→(-x,-y) (180° about the origin)

1.p(-3,2) ,in the second quadrant

P(-2,-3) is in 4th quadrant.

in the clockwise it is rotation of 270° about the origin.

Q(-4,-5) is in 4th quadrant.

Q(4,5) is in 1st quadrant.

so it is 180° rotation in the clockwise direction.

R(1,7) is in 1st quadrant.

R(7,-1) is in 4th quadrant.

Hence it is 90° rotation about the origin in clockwise direction.

You can take in x values starting from -4 to 4. Substitute the x values in the equation and find the y values.

Using the values, you can plot the line.

Easy :)
