43.85 + (2*2.70) - (2*1.10) - 4.45 = $42.60
Or more simply 43.85 + 2.70 + 2.70 - 1.10 - 1.10 - 4.45 = $42.60
Answer:
x²-10×+25=16
ײ-10×=16-25
×(×-10)=-9
but if your question is rather 2x-10×+25=16
then here goes the answers
2x-10×+25=16
-8×=16-25
-8×=-9
×=9/8
×=1¹/8
HOW TO:
* use slope intercept form
1) find the slope
slope = rise/run (rise divided by the run)
slope = -4/2
slope = -2
2) find the y-intercept (just the point where the line intersects the y-axis)
y-intercept is (0,-4)
3) use slope-intercept form:
y = mx + b (m stands for the slope, b stands for the y-intercept)
y= -2x + (-4)
y= -2x - 4
So your equation is y= -2x-4
Q - r = r
Flip
r = Q - r
Add r to both sides
2r = Q
Divide both sides by 2
r = Q/2
Have an awesome day! :)
