Answer:
(-1,4)
Step-by-step explanation:
First lets put the two equations into y=mx+b format by subtracting 2x and 4x to the right side of their equations.
y=-2x+2
y=-4x+0
Now you can put this into a system of equations, but you can also plug in the coordinates to see if both equations are equal. I will show system of equations solution.
-2x+2=-4x, solve this by adding -2x to the right side so that the 2 is by itself.
Now you have 2=-2x. Divide by -2 to get the x by itself, now you have x=-1. Plug this back into one of the equations, so y=-4x would be y=-4(-1), so y=4.
Answer:
-1,4

Remove all perfect squares from inside the square root √30b∧5
Answer:
[tex]b^{2}\sqrt{30b}[/tex]
Step-by-step explanation:
30 only has factors of 2×3×5, so the only perfect square here is [tex]b^{2}[/tex], and so you factor that out.

At a collage bookstore Clara purchased a math textbook and a novel that cost a total of $54 not including tax if the price of the math textbook m is $8 more than 3 times the price of the novel n which system of linear equations could be used to determine the price of each book
Answer:
m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.
Step-by-step explanation:
Given,
Total cost of maths book and novel = $54
Let,
Cost of maths book = m
Cost of novel = n
According to given statement;
m+n=54 Eqn 1
the price of the math textbook, m, is $8 more than 3 times the price of the novel
m = 3n+8 Eqn 2
m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.

Answer:
∠D = 18.4°Step-by-step explanation:
use the formula
tanФ⁻¹ = y/x
where y = 3
x = 9
plugin values into the formula:
tanФ⁻¹ = y/x
= 3/9
tanФ⁻¹ = 0.3
Ф = inv. tan 0.3
Ф = 18.4°
therefore, the angle D = 18.4°
What is mRTS R(4x+11) S 43 T(7x-6)
Answer:
X= 12 (see explanation)
Step-by-step explanation:
I'm doing my best to interpret this without an image. So angle S= 43 degrees, T is 7x-6 and R is 4x+11.
If the sum of the arc RTS= 360 degrees, then do
360= 43+ (7x-6) + (4x+11)
X= 312/11 <- this looks iffy
If the sum of the arc RTS= 180 degrees, then do
180= 43+ (7x-6) + (4x+11)
X= 12 <- this looks like a normal solution
Amy, Bruce, and Carlos collected a total of 168 pounds of cans to recycle. Bruce collected 1/3 the number of pounds of cans Carlos collected. Amy collected the same number of pounds of cans as Bruce and Carlos combined. Solve the equation for c, and then determine the number of pounds of cans Bruce collected.. Show all work necessary to support your answer
Answer:
[tex]c = 63\\b=21[/tex]
Step-by-step explanation:
Let number of pounds of cans collected by Amy = [tex]a[/tex]
Let number of pounds of cans collected by Bruce = [tex]b[/tex]
Let number of pounds of cans collected by Carlos = [tex]c[/tex]
As per question statement, total number of cans collected = 168
[tex]a+b+c=168[/tex] ..... (1)
Number of pounds collected by Bruce is [tex]\frac{1}{3}[/tex]rd of the pounds of cans collected by Carlos.
[tex]b = \dfrac{1}{3}c ..... (2)[/tex]
Number of pounds collected by Amy is equal to number of pounds collected by Bruce and Carlos combined.
[tex]a = b+c[/tex]
Using equation (2):
[tex]a = \dfrac{1}{3}c +c \\\Rightarrow a =\dfrac{4}{3}c ..... (3)[/tex]
Using equations (2) and (3) in equation (1), we get:
[tex]\dfrac{4}{3}c+\dfrac{1}{3}c+c =168\\\Rightarrow \dfrac{8}{3}c = 168\\\Rightarrow c =63[/tex]
Using equation (2):
[tex]b = \dfrac{63}{3} = 21[/tex]

If you earn $13/hour and you work 2 hours overtime at a rate of time and a half, how much will you earn for each hour of overtime?
Answer:
32.50
Step-by-step explanation:
It is simple. You need to know the basics of money, fractions, and well... Math! :)
if you take 13 and multiply it by 2 you get 26
Take the 26 and put it aside -------------> 26
divide 13 in half. that would be 6.50
6.50 + 6.50 = 13
Now get the 26 --------------------------> 26
and add 6.50 to 26.
That would be 32.50!

The graph shows a function f(x). Determine the following values.
F^-1 (4)=
F^-1 (-5)=
F^-1 (0)=
Answer:
f^-1(4) = 2
f^-1(-5) = -4
f^-1(0) = 0
Step-by-step explanation:
To find the inverse of the function, we simply switch the places of x and y
You simply find the value given on the y-axis and trace to the x-axis
Thus, we have the following ;
f^-1(4) = 2
f^-1(-5) = -4
f^-1(0) = 0

An equiangular triangle is ___ an acute triangle.
Always, sometimes, or never
Answer:
Always
Step-by-step explanation:
An equiangular triangle is a triangle with three congruent interior angles. The angles of any triangle add up to 180 degrees. With three angles in a triangle that are all equal, this means each angle is 60 degrees (because 180 divided by 3 is 60).
An Acute triangle is a triangle with all of its angles being something less than 90 degrees. Since an equiangular triangle's angles all measure as 60 degrees, then the statement in the question is always true.
