We need to convert this equation to slope-intercept form first.
We can do that by solving for y.
x - 5y = 15
<em><u>Add 5y to both sides.</u></em>
x = 5y + 15
<em><u>Subtract 15 from both sides.</u></em>
x - 15 = 5y
<em><u>Divide both sides by 5.</u></em>
y = 1/5x - 3
We now know the slope is 1/5.
The slope of the line perpendicular to the line with a slope of 1/5 is -5.
The slope of a perpendicular line is the negative reciprocal of the original slope.
Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).
The equation of the new line is y = -5x - 6.
Divide 120 by 4 and your answer will be: Rya can drive 30 miles on 1 gallons of gas.
10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.
.009*4000=$36.00
It will cost $36.00 to seed the 4,000 square feet at that price.
0.25 is a demimal
the one to the right of that is a ratio
the one under that is equivalent fractions
the one the right of equivalent fractions is simplest form
Answer:
Ratio of area of triangles MNP and ABC is 1.05
Step-by-step explanation:
There are 2 triangles ABC and MNP.
We are given that ,m∠A = m∠M.
AB = 16 and AC = 10.
MN = 7 and MP = 24.
Area of a triangle ∝ Product of any two sides.
So area of triangle ABC ∝ 16
Area of triangle ABC = 160
,
where k is a constant.
So area of triangle MNP ∝ 7 
Area of triangle MNP = 168
So ratio of area of triangles = 
= 
= 1.05
