Answer:
Both versions of the expression equal the exact same amount;one is just much shorter.Simplifying algebraic expressions is the same idea,except you have variables in your expression.So,Basically you're turning a long expression into something you can easily make sense of
we know that
If the point has an nonzero abscissa (x coordinate) then it can be located in any of the four quadrants
If the point has an negative ordinate (y coordinate) then it can be located in Quadrant III or Quadrant IV
therefore
the answer is the option
Quadrant III or Quadrant IV
We would find the mean. So:
15 + 12 + 17 + 13 + 20 + 19 = 96
Divide the sum by the amount of numbers added together.
So: 96/ 16
The mean or average is 16
<span>-2x+5y=-10
Substitute 0 for y
</span><span>-2x+5(0)=-10
Multiply 5 by 0
-2x=-10
Divide both sides by -2
Final Answer: x=5

Answer: y = 1x + -4
Equation of a straight line:
y = mx + b ------(i)
Step by Step Solution:
Step 1: Calculating Slope (m).
m = y2-y1 /x2-x1
m = 3--1 /7-3
m = 4/4
m = 1
Now putting value of m in equation (i)
y = 1x + b -----(ii)
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (3,-1) for calculating y-intercept:
y = mx + b
-1 = 1(3) + b
-1 = 3 + b
-4 = b
b = -4
Now putting value of b in equation (ii)
y = 1x + -4
