A: What are the solutions to the quadratic equation x^2+9=0?
Nataliya [291]

Answer:

Part A)

x=-3i

x=3i

Part B)

(x+3i)(x-3i)

Step-by-step explanation:

Given:

Part A)

x^2+9=0

x^2=-9

x= √-9

x=√-1 *√9

x=± i *3

x=±3i

Part B)

x^2+9=0

x^2 - (-9)=0

x2-(3i)^2=0

(x-3i)(x+3i)=0 !

antiseptic1488 [7]

Answer:

D

Step-by-step explanation:

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

−4y+4y+2=2

Step 1: Simplify both sides of the equation.

−4y+4y+2=2

(−4y+4y)+(2)=2(Combine Like Terms)

2=2

2=2

Step 2: Subtract 2 from both sides.

2−2=2−2

0=0

Answer:

All real numbers are solutions.

A line that includes the points (8,0) and (9,s) has a slope of 9. What is the value of s?
scZoUnD [109]

Answer:

s = 9

Step-by-step explanation:

We can find the slope given two points

m = (y2-y1)/(x2-x1)

 9 = (s-0)/(9-8)

 9 = (s)/1

S = 9
