6 0

Answer:

1 Answer->3

Step-by-step explanation:

To factor this out find the factors of 9 which add up to 6.

3 and 3 work therefore factor it out to

(x+3)(x+3)=0

Using Zero product property x is equal to -3

And there is only one answer which is 3

What are the discontinuities of the function y= 1500/x

Ratling [72]

The discontinuity occurs at x = 0, since that is the only "problem" place in the graph that makes the function undefined. A vertical asymptote exists there. It is nonremoveable.

Solve the quadratic equation below for the exact values of x:<br> 4x^2-5=75

grandymaker [24]

Step-by-step explanation:

$4 {x}^{2} - 5 = 75 \\ 4 {x}^{2} = 75 + 5 \\ 4 {x}^{2} = 80 \\ {x}^{2} = \frac{80}{4} \\ {x}^{2} = 20 \\ x = \pm \sqrt{20} \\ x = \pm 2 \sqrt{5}$

The angle measurements in the diagram are represented by the following expressions.

Aleonysh [2.5K]

Answer:

x = 6

∠B = 126

Step-by-step explanation:

∠A = ∠B through alternate interior angles

∠A = ∠B

8x + 78 = 2x + 114

8x - 2x = 114 - 78

6x = 36

x = 36 ÷ 6

x = 6

∠B = 2x + 114

2(6) + 114

12 + 114

= 126

5) 3(8+ n) - 15 = 24

scoundrel [369]

•First you multiply parentheses by 3 24+3n-15=24
•then u cancel equal terms 3n-15=0
•Move the constant to the right
3n-15=0
3n=15
•Divide both sides by 3
Answer is n=5 ☺️
