I believe it’s A sorry if it’s incorrect
Step-by-step explanation:
<u>Y2 - Y1</u>
X2 - X1
<u>3 - 1</u>
2 - 1
= 2
y - Y1 = m (x - X1)
y - 1 = 2(x - 1) --- IN POINT SLOPE FORM
y - 1 = 2x - 2
+ 1 + 1
y = 2x - 1 --- IN SLOPE INTERCEPT FORM
QUESTION 12:
Slope intercept form -
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
- When the slope is negative, you go down
- When the slope is positive, you go up
ABOUT PROBLEM:
- Since the slope is negative, you go down 4, right 3, but start from the 2 then start doing the slope
- You have to put 2 on the y - line because it's the y - intercept AKA starting point
y = -4/3x + 2
Answer:

Step-by-step explanation:
I = P*R*T
1100*.05*3
You would do 410,000 divided by 250,000 and that would be the answer. let me know if this is correct or not.
Short AnswerThere are two numbers
x1 = -0.25 + 0.9682i <<<<
answer 1x2 = - 0.25 - 0.9582i <<<<
answer 2 I take it there are two such numbers.
Let one number = x
Let one number = y
x + y = -0.5
y = - 0.5 - x (1)
xy = 1 (2)
Put equation 1 into equation 2
xy = 1
x(-0.5 - x) = 1
-0.5x - x^2 = 1 Subtract 1 from both sides.
-0.5x - x^2 - 1 = 0 Order these by powers
-x^2 - 0.5x -1 = 0 Multiply though by - 1
x^2 + 0.5x + 1 = 0 Use the quadratic formula to solve this.

a = 1
b = 0.5
c = 1

x = [-0.5 +/- sqrt(0.25 - 4)] / 2
x = [-0.5 +/- sqrt(-3.75)] / 2
x = [-0.25 +/- 0.9682i
x1 = -0.25 + 0.9682 i
x2 = -0.25 - 0.9682 i
These two are conjugates. They will add as x1 + x2 = -0.25 - 0.25 = - 0.50.
The complex parts cancel out. Getting them to multiply to 1 will be a little more difficult. I'll do that under the check.
Check(-0.25 - 0.9682i)(-0.25 + 0.9682i)
Use FOIL
F:-0.25 * -0.25 = 0.0625
O: -0.25*0.9682i
I: +0.25*0.9682i
L: -0.9682i*0.9682i = - 0.9375 i^2 = 0.9375
NoticeThe two middle terms (labled "O" and "I" ) cancel out. They are of opposite signs.
The final result is 0.9375 and 0.0625 add up to 1
