Answer: 10n^2+n+9
Answer:
y= -3x + 8
Step-by-step explanation:
Put -2x + 6y = -4 into slope-interceltp form
Take the negative reciprocal of the slope.
Use this reciprocal in point-slope form
and you have,
= y= -3x + 8
<em>(EDITED)</em> Steps:
2x+6y = -4
6y=2x - 4
y= 1/3x + 2/3
if two lines are perpendicular,
m1 * m2 + -1
1/3 * m2 = -1
m2 = -3
the line perpendicular to this line is
y = -3x + k ; k ∈ R
the line passes through the point (5,-7)
so,
-7 = -3. (5) +k
-7 = -15 + k
k = 8
∴the equation of a line that passes through the point (5,-7) and is perpendicular to the line -2x+6y=-4 is
y= -3x + 8
Hope this helps, have a nice day/night! :D
Answer:
False
Step-by-step explanation:
You are only given one side and one angle. We cannot determine if the triangles are similar. We need 3 pieces of information (ASA, SSS, SAS, or AAA) to determine if the triangles are similar).
First, distribute on both sides.
w^2+6^2=3w+36-w^2
Simplify 6^2.
w^2+36=3w+36-w^2
Subtract w^2 from both sides.
36=3w+36
Subtract 36 from both sides.
0=3w
Divide both sides by 3.
0=w
Number of cars washed by the eight teams per hour = 2 * 8 = 16 cars.
Number of cars washed by the eight teams in 5 = 16 * 5 = 80 cars.
The teams should charge $600/80 = $7.50
