0.035x+0.045x=427.50
0.08x=427.50
x=427.50/0.08
x=5343.75
x+x+1500=5343.75
2x=5343.75-1500
2x=3843.75
x=1921.88 first
1921.88+1500=3421.88 second
Answer:
-7/6
Step-by-step explanation:
The slope formula can be used with any pair of points.
m = (y2 -y1)/(x2 -x1)
m = (1 -8)/(-2 -(-8)) = -7/6
The slope of the line is -7/6.
I don’t see the question.
Answer:
The vertical distance from the origin to the point (2,9) is 9
Or
9.2195
Step-by-step explanation:
It's 9 because y coordinate gives the vertical distance.
Or
It might be 9.2195 because they tell us the point is 2.9 and they are asking the distance from the origin which is zero. So we can use Pythagorean theorem. A²+B²=C² Look at it as a triangle. They have given us A and B, so you can find C² using those information. If you plot the point in the line you know that A=2 and B=9. Using the formula will be 2²+9²=C² ⇒ 4+81=C² ⇒ 85=C². To get rid of the power of 2 in c we have to square both side to cancel it out. C would equal 9.2195
Answer:
x = StartFraction negative 5 plus or minus StartRoot 5 EndRoot Over 2 EndFraction
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate the function to zero
so
substitute in the formula
therefore
x = StartFraction negative 5 plus or minus StartRoot 5 EndRoot Over 2 EndFraction
