Answer:
We need to solve this system of equations by substitution:
-6x-2y =20
3y=x
Yu can do it with the letter you decide
You can get the x from the second equation and replace in the first:
3y = x
-6x - 2y = 20 -> -6(3y) - 2y = 20 --> -18y - 2y = 20 --> y=-1
Then we can replace in the second one:
3*(-1) = x ---> -3 = x
So the answer is x = -3, y = -1

Answer:
80%
Step-by-step explanation:
Write a function rule for the table.
Answer:
Option C - c= 23d+11
Step-by-step explanation:
Days are assumed as "d" and cost is assumed as "c".
34 = 23(1)+1157 = 23(2)+1180 = 23(3)+11103 = 23(4)+11So the option is C.

Find the inverse of the function. Is the inverse a function? f(x) = (x − 2)2
Answer:
[tex]f^{-1}(x)=\sqrt{x}+2[/tex]
Step-by-step explanation:
Given function is,
f(x) = (x - 2)²
Step - 1
Rewrite the function in the form of a equation.
y = (x - 2)²
Step - 2
Interchange the variables 'x' and 'y',
x = (y - 2)²
Step - 3
Solve the equation for y,
x = (y - 2)²
y - 2 = √x
y = 2 + √x
Step - 4
Rewrite the equation in the form of a function,
[tex]f^{-1}(x)=\sqrt{x}+2[/tex]

What is the slope :( help
Answer:400
Step-by-step explanation
in order to find slope you put the change in y over the change in x, y gains 1200 units while x gains 3 units, this means we get 1200/3 and we can simplify it to 400
Answer:
400
Step-by-step explanation:
We can use the formula [tex]\frac{rise}{run}[/tex] to find slope!
So first we find points on the graph. The first point we see is 600. The second point we see is 1,400. Next, we find the rising distance between 1,400 and 600 which is 800. Now we look at the running distance which is 2. Now we plug it into the [tex]\frac{rise}{run}[/tex] formula.
The formula should now look like this:
[tex]\frac{rise}{run}\\[/tex] = [tex]\frac{800}{2}[/tex]
[tex]\frac{800}{2}[/tex] = 400
So the slope is 400

Which expressions show the volume and the surface area of this cube-shaped packing box?
A cube with a dimension of 1 and five-eighths feet.
Answer and Step-by-step explanation:
The bottom right answer choice is the answer.
To find the volume, you do (length × width × height)
And to get the surface area, you do [tex]6(x)^{3}[/tex]
We just have to plug 1 [tex]\frac{5}{8}[/tex]
Where did they get [tex]\frac{13}{8}[/tex]?
They made the mixed fraction into a fraction by multiply 8 by 1, then adding that product to 5.
Which leads us to the answer choice being the bottom right.
#teamtrees #WAP (Water And Plant)
Answer:
D. V = (13/8)³ ft³, SA = 6(13/8)² ft²Step-by-step explanation:
Volume of the cube:
V = a³Surface area of the cube:
SA = 6a²Given cube has side of 1 5/8 feet = 13/8 feet
Substitute the value of a:
V = (13/8)³ ft³SA = 6(13/8)² ft²Correct option is D

A rectangle has sides of length 8cm and 3.2cm. Calculate the angle between the diagonal and a shorter side.
Answer:
The angle is 68.2 degrees
Step-by-step explanation:
Let us have the shorter side as the width
In that case, the opposite will be the length which is 8 cm
The diagonal is the hypotenuse
The short side is the adjacent
The trigonometric ratio that links the opposite and the adjacent is the tan
tan of an angle is the ratio of its opposite to the adjacent
In this case,
tan theta = 8/3.2
theta = arc tan (8/3.2)
theta = 68.2 degrees
Solve the simulataneous equations. 5x-4y=19 x+2y=8
Answer:
(5, 1.5 )
Step-by-step explanation:
Given the 2 equations
5x - 4y = 19 → (1)
x + 2y = 8 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
2x + 4y = 16 → (3)
Add (1) and (3) term by term to eliminate y
7x + 0 = 35
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5 + 2y = 8 ( subtract 5 from both sides )
2y = 3 ( divide both sides by 2 )
y = 1.5
solution is (5, 1.5 )
