Here you go, The answer is 8.75
Answer:
x=2 and y=-1. The steps--
Step-by-step explanation:
<em>FIRST STEP: </em>SUBSTITUTE -4y with the definition in y=2x-5. This makes the first equation -3x-4(2x-5)=-2
<em>SECOND STEP: </em>DISTRIBUTE -4 throughout the parenthesis, making the equation -3x-8x+20=-2.
<em>LAST STEP: </em>SOLVE by combining like terms, -3x-8x, to make -11x, and subtracting 20 from each side, to make -11x=-22. Then divide both sides by -11, making x=2. From there, you solve that y=2(2)-5, solving that y=4-5, y=-1.
Therefore, x=2 and y=-1
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
To find the slope(m), use the slope formula:
And plug in the two points on the line
(-4, -4) = (x₁, y₁)
(4, -2) = (x₂, y₂)
(two negative signs cancel each other out and become positive)
Simplify the fraction
Now that you know the slope, substitute/plug it into the equation
y = mx + b
To find b, plug in either of the points into the equation, it doesn't matter which, then isolate/get the variable "b" by itself. I will use (4, -2)
-2 = 1 + b Subtract 1 on both sides to get "b" by itself
-3 = b
Your answer is A
38,000 because 8137 rounds to 8000 so just add the 30,00 so it's 38,000
