Answer:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have y=5x−8 and we can substitute this value of y in the other equation
4x+3y=33
4x+3(5x−8)=33 we can solve now for x
4x+15x−24=33
19x=33+24
19x=57
x=5719=3.
y can be obtained from the first equation
y=5x−8
y=5⋅3−8=15−8=7
Then x=3 and y=7.
Step-by-step explanation:
Answer:
x = 3
y = 7
Step-by-step explanation:
y = 5x - 8 ---------------(I)
4x + 3y = 33 ------------(II)
Substitute y = 5x - 8 in equation (II)
4x + 3 (5x - 8) = 33
4x + 3*5x - 8*3 = 33
4x + 15x - 24 = 33 {Combine like terms}
19x - 24 = 33 {Add 24 to both sides}
19x = 33 + 24
19x = 57 {Divide both sides by 19}
x = 57/19
x = 3
Substitute x = 3 in equation (I)
y = 5*3 - 8
y = 15 - 8
y = 7

Find angle E and F please
Answers
Answer:D 120 degrees, F 60 degrees
Step-by-step explanation:
it is a parallelogram which means the 2 angles add up to 180 degrees. 5x+2x+12=180. Then solve, 7x=168, x=24. Then Substitute back into the angles. E is 5*24 which is 120. F is same as D which is 2x+12=60. Hope this helped
Answer:
Angle F = 60
Angle E = 120
Step-by-step explanation:
Angle E = Angle G whereas Angle D = Angle F
Angle D + Angle G = 180, Angle E + Angle F = 180
Angle D + Angle E + Angle F + Angle G = 360
In this case, it's Angle E and F. Keep in mind that Angle D is the same as Angle F so you can just do 5x + 2x+12 = 180.
Subtract 12 on both sides to get 168, so the equation is 5x + 2x = 168.
Add 5x and 2x to get 7x. Your final equation is 7x = 168
Divide 7 on both sides to get 24.
So x = 24
Now plug in x in for both angle equations so Angle F = 2(24) + 12 and you get 60.
For Angle E you plug in 5(24) and you get 120.

HELP!! Identify the transformation from ABC to A'B'C'.
1. Reflection over the y-axis
2. 90 degree rotation
3. 270 degree rotation
4. Reflection over the x-axis
Answers
Answer:
Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.
Choice 1.
Step-by-step explanation:
Reflection over the x-axis
Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).
The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)
Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Answers
Answer: 33.75
Step-by-step explanation:
It’s right
There is a profit of $33.75 for recycling 75 pounds of aluminum.
What is Function?A function is a relation from a set to another set such that element in the first set only maps to one element in the other set.
A function f from a set A to a set B can be represented as f : A → B
We have,
Profit for recycling 10 lb Aluminum = 10/10 × 4.5 = 4.50
Profit for recycling 20 lb Aluminum = 20/10 × 4.5 = 9.00
and so on
Therefore, we can write this as a function.
f(x) = [tex]\frac{x}{10}[/tex] × 4.5
We have to find the profit for recycling 75 pounds of aluminum.
f(75) = [tex]\frac{75}{10}[/tex] × 4.5
= 7.5 × 4.5
= 33.75
Hence the profit for recycling 75 pounds of aluminum is $33.75.
