Answer:
x = 1 y = -3 (1, -3)
Step-by-step explanation:
Use the Substitution Method
First, you have to turn the equations into slope intercept form (y = mx + b)
First equation
x - y = 4
subtract x from both sides
-y = -x + 4
divide each side by -1
y = x - 4
Second Equation
4x + y = 1
subtract 4x from both sides
y = -4x + 1
Turn the two new equations into one equation like so
-4x + 1 = x - 4
add 4x to both sides
1 = 5x - 4
add 4 to both sides
5 = 5x
divide each side by 5
x = 1
Fill in x in one of the original equations in order to find the value of y
4(1) + y = 1
4 + y = 1
subtract 4 from both sides
y = -3
The solution is (1, -3)hope this helps :)

Explanation:
This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.
The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.
Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.

What is the area of the triangle whose vertices are (-4,0), (-10, 0) and (-7,-6)?
Step-by-step explanation:
From the point -10 to -4, there is a difference of 6 units. Base = 6
From the x-axis to the furthest point, there is a difference of 6 units. Height = 6
6*6 = 36
36/2 = 18
Area = 18

(a) Whats the area of a rectangular field is 3888 m. If the length of the field is 72 m, what is its width?
(b)The perimeter of a rectangular painting is 374 cm. If the width of the painting is 88cm, what is its length?
Answer:
part a is 54 part b is 99
Step-by-step explanation:
72 x ? =3888
x=54
374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198
so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2
so the top and bottom of the rectangle are 99 and both sides are 88

24<8+4x what equals x?
Answer:
x > 4
Step-by-step explanation:
Flip the equation.
24<8+4x
4x+8>24
Subtract 8 from both sides.
4x+8-8>24-8
4x>16
Divide both sides by 4.
4x/4>16/4
x > 4

Makayla can type 360 words in 8 minutes. At
this rate, how many words can she type in
3 minutes?
Answer:
135
Step-by-step explanation:
360/8=45
so she can type 45 words a minute
45 x 3=135 words in 3 minutes
Step-by-step explanation:
no. of words she can write in 8 mins = 360
no. of words she can write in 1 min = 360/8
no. of words she can write in 3 mins = 360/8*3 = 135 words
Which of the following are true of the sample of 40 voters? Check all that apply.
The sample is not randomly chosen.
The sample should be larger to give more reliable information.
The sample size is too large to make inferences.
The sample size is too small to represent the population.
The sample size is too small and will show larger variation.
The sample is invalid because it randomly chooses voters.
The sample size is too small and can lead to false inferences.
Which expression is equivalent to the given expression?
(3m-4) (375)
9514 1404 393
Answer:
D. 81/m^7
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
__
Using these, your expression simplifies to ...
[tex](3m^{-4})^3(3m^5)=(3^3)(3)(m^{-4\cdot3+5})=81m^{-7}=\boxed{\dfrac{81}{m^7}}[/tex]
