Step-by-step explanation:
The lines 2x - y = 8 and 4x - 2y = 16 intersect at _______.
The solution is Option C.
The system of equations are same and they have infinite number of points
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first equation be P
2x - y = 8 be equation (1)
Let the second equation be Q
4x - 2y = 16 be equation (2)
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ ) = 2
Substituting the values in the equation , we get
Divide equation (2) by 2 , we get
2x - y = 8 be equation (1)
Therefore , the value of equation (1) = equation (2)
Hence , there are infinite number of solutions to the equations

An expression is shown below:
2x3 + 10x2 − 4x2y − 20xy
Part A: Rewrite the expression so the GCF is factored completely.
The given expression can be rewritten as 2x(x²+5x-xy-10y).
The given expression is 2x³+10x²-2x²y-20xy.
What is GCF?GCF stands for the greatest common factor. The greatest common factor of two numbers is the greatest number that is a factor of both of them.
Now, 2x³=2×x×x×x, 10x²=2×5×x×x, 2x²y=2×x×x×y and 20xy=2×x×x×y
Here, the GCF of all the terms is 2x.
So, the expression becomes 2x(x²+5x-xy-10y).
Therefore, the given expression can be rewritten as 2x(x²+5x-xy-10y).

What is the smallest whole number that can be multiplied by 300 such that the product is a perfect cube?
300=2×2×5×5×3
We observe that 2 and 5 are grouped in pairs and the 3 is left unpaired.
If we multiply 300 by the factor 3 then
300×3=2×2×5×5×3×3
900=2×2×5×5×3×3 which is a perfect square.
∴ Required number is 3
root of 900 =30

solve for x
5 = 1/5x - 3
Answer:
x = 40
Step-by-step explanation:
5 = 1/5x -3
Add 3 to both sides
8= 1/5x
Multiply both sides by 5 to get rid of the fraction. (because no one likes fractions, lol)
40 = x
Check the math:
5= 1/5(40) -3
5 = 8-3

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of paint are needed for one door? Consider drawing a model to help you solve the problem.
Answer:
1 and 1/4 liters of paint are needed for one door
Step-by-step explanation:
You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 and 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.

1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.
2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).
3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.
Enter your answer in the form "y = …".
4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
5. In the third picture is a portion of the graph of a function, y=u(x):
What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
Answer:
Q1The graph of y = f(x), has vertex at (1, -2)
The vertex of a function f(x - 3) is going to be:
(1 - 3, -2) = (-2, -2)Q2The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).The axis of symmetry is at the same distance from the symmetric points.
x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2
The point is (2, -7)
Q3The graph in blue is the translation of the red to the left by 2 units.
So the equation is:
y = f(x + 2)Q4y = h(x) is graphed
h(7) = 5h(h(7)) = h(5) = -1Q5The graph of the function y = u(x) given
This is a odd function.
The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)
Therefore:
u(-2.72) + u(-0.81) + u(0.81) + u(2.72) = [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] = 0 + 0 = 0What is x in 2.
