What is an equation of the line that is perpendicular to -x+3y=9 and passes through the point (-3,2)
Answers
Answer:
y=-3x-7
Step-by-step explanation:
the line is currently in standard form (ax+by=c). Let's put it into slope-intercept form (y=mx+b)
-x+3y=9
add x to both sides
3y=x+9
divide by 3
y=1/3x+3
perpendicular lines have slopes that when multiplied, equal -1.
to find the slope (m) of our new line:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3
here's our equation so far:
y=-3x+b
we need to find b (y intecept)
since the line passes through the point (-3,2), it should be a solution in the equation (plug it in, and the result is a true statement). We can also use it to find b
so, substitute the pointt into the equation:
2=-3(-3)+b
multiply
2=9+b
subtract
-7=b
so the equation of the line is y=-3x-7

come up with and example of three side lengths that cannot possibly make a triangle
Answers
Answer:
2, 7, 12
Step-by-step explanation:
According to the triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle with side lengths 2, 7 and 12, since 2 + 7 is less than 12.

A circular garden has a diameter of 10 yards. What is the area of the garden?
Use 3.14 for T.
Answers
Answer:
78.5 yards
Step-by-step explanation:
Essentially, to find the area of a circle simply use the equation pi r^2 (r=radius, or half of diameter). They also make it really easy by saying we may use 3.14 for pi, so really, we simply have to solve:
(3.14)5^2=78.5 yards

A person invests $2,730 in an account that earns 4.2% annual interest. Find when the value of the investment reaches $5,000. If necessary, round to the nearest tenth.
Answers
Step-by-step explanation:
You want to calculate the interest on $2730 at 4.2% interest per year after 5,000 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:P is the principal amount, $2730.00.
r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 2730 × 0.042 × 5 to get that:
The interest is: $573.30

Answer: (-6,2)
-8 + (-4) / 2 = -6
-6 + 10 / 2 = 2
Answer:
M = (-6,2)
Step-by-step explanation:
To find a midpoint, you add the x-coordinates and divide by 2 to get the new x coordinate and then add the y-coordinates and divide by 2 to get the new y-coordinate.
(-8 + -4) /2 = x of M
(-6 + 10)/2 = y of M
M = (-6, 2)
