The answer is number two.
Answer:
the ans is 6 it was a easy one
There are 2 mixed numbers in <span>1 2/3 * 1 7/10. One is 1 2/3; the other is 1 7/10.
Convert both to improper fractions: 1 2/3 becomes 5/2, and 1 7/10 becomes 17/10.
5 17
Then your task is to multiply ---- * ----- , which, after reducing 5/10, becomes
2 10
17/4 (answer)</span>
Answer:
y+4=-(2/5)(x-5) ----> equation of the line into point slope form
y=-(2/5)x-2 ----> equation of the line into slope intercept form
2x+5y=-10 ----> equation of the line in standard form
Step-by-step explanation:
step 1
Find the slope of the given line
we have
5x-2y=-6
isolate the variable y
2y=5x+6
y=2.5x+3
The slope m of the given line is m=2.5
step 2
Find the slope of the line perpendicular to the given line
We know that
If two lines are perpendicular, then their slopes are inverse reciprocal each other
so
m1=5/2
the inverse reciprocal is
m2=-2/5
step 3
Find the equation of the line into point slope form
y-y1=m(x-x1)
we have
m=-2/5
point (5,-4)
substitute
y+4=-(2/5)(x-5) ----> equation of the line into point slope form
y=-(2/5)x+2-4
y=-(2/5)x-2 ----> equation of the line into slope intercept form
Multiply by 5 both sides
5y=-2x-10
2x+5y=-10 ----> equation of the line in standard form
Slope = (y2 - y1) / (x2 - x1)
slope = (5 + 7)/(10 - 4) = 12/6 = 2
point slope form:
y - y1 = m(x - 1)
in this case:
If you use point (4,-7) then equation will be:
y -(- 7) = 2(x - 4)
y + 7 = 2(x - 4)
If you use point (10,5) then equation will be:
y - 5 = 2(x - 10)
Answer:
B. y - 5 = 2(x - 10)
