Answer:

  1. x2 − 15 = 2x
  2. x2 − 2x − 15 = 0
  3. (x − 5)(x + 3) = 0
  4. x − 5 = 0 or x + 3 = 0
  5. Potential solutions are −3 and 5

Step 1: x²-15=2x
step 2: x²-2x-15=0
step 3: (x-5)(x+3)=0
step 4: x-5=0 or x+3=0
step 5: x=5 of x=-3

Which of the fallowing points are the solution to the equation 3x-4y-8=12. Chose all that apply (0,-5) (4,-2) (8,2) (-16,-17) (-
Virty [35]

Answer:

The solutions for the equation are:

(4,-2) and (-16,-17)

Step-by-step explanation:

Given equation:

3x-4y-8=12

Given points:

(0,-5), (4,-2), (8,2), (-16,-17), (-1,-8), (-40,-34)

We will check each point by plugging it in the given equation and see if it satisfies the equation or not.

(0,5)

3(0)-4(5)-8=12

0-20-8=12

-28=12

which is not true. Hence, not a solution.

(4,-2)

3(4)-4(-2)-8=12

12+8-8=12

12=12

which is true. Hence, it is a solution.

(8,2)

3(8)-4(2)-8=12

24-8-8=12

24-16=12

8=12

which is not true. Hence, not a solution.

(-16,-17)

3(-16)-4(-17)-8=12

-48+68-8=12

20-8=12

12=12

which is true. Hence, it is a solution.

(-1,-8)

3(-1)-4(-8)-8=12

-3+32-8=12

21=12

which is not true. Hence, not a solution.

(-40,-34)

3(-40)-4(-34)-8=12

-120+136-8=12

8=12

which is not true. Hence, not a solution.

If angle 1 = 10x + 4 and angle 2 = 5x – 4, find angle 2<br> a.)56<br> b.)78<br> c.)12<br> d.)65
Semenov [28]
Angle 1 and 2 are supplementary angles, meaning they must add up to 180°. You can tell this because they share a side and together, their other side forms a straight line (and straight lines are 180<span>°).

Knowing this, you can make an equation to solve for x:
Angle 1 + Angle 2 = 180</span><span>°
</span>10x + 4 + 5x – 4 = 180°
15x = 180°
x = 12°

Knowing x = 12°, you can plug the value of x into the equation for angle 2 to find its measurement:
<span>Angle 2 = 5x – 4
</span>Angle 2 = 5(12°) - 4
Angle 2 = 56°

--------

Answer: A) 56°
