Answer:Let's solve your equation step-by-step.

24=x2−4x+3

Step 1: Subtract x^2-4x+3 from both sides.

24−(x2−4x+3)=x2−4x+3−(x2−4x+3)

−x2+4x+21=0

Step 2: Factor left side of equation.

(−x−3)(x−7)=0

Step 3: Set factors equal to 0.

−x−3=0 or x−7=0

x=−3 or x=7

Answer:

x=−3 or x=7

5) Mario owns a plumbing business. He charges an hourly rate plus a onetime set up fee. His first job was 4 hours and he charged

Wittaler [7]

Answer:

Results are below.

Step-by-step explanation:

First, we need to calculate the variable income per job:

First job= 450 - 150= 300

Second job= 675 - 150= 525

Now, the hourly rate:

Hourly rate= total variable income / number of hours

First job= 300 / 4= $75

Second job= 525 / 3= $175

It is probably that the second job was 7 hours long. If not, he doesn't charge the same amount per hour

What is the measurement of angle 1 plz help me !

Evgen [1.6K]

Answer:

ANGLE 1 = 40°

Step-by-step explanation:

angle 1 = angle 2 ------(alternate interior angles)

2x + 20 = 3x + 10

20 - 10 = 3x - 2x

x = 10.

Angle 1 = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°.
