Answers
Answer:
3: equally likely
4: likely
Step-by-step explanation:
Question 3:
the spinner has 1, 2, 3, 4, 5, 6
2, 4, 6 are all even number which is 3 / 6 = 1 / 2
so half a chance can be odd or half even possibility of landing
Question 4:
- 13 yellow
- 4 green
- 3 blue
total marbles: 13 + 4 + 3 = 20
yellow / total = 13 / 20
which is more than half of the marbles are yellow

is this a quadratic function 2x+13=13
Answers
Answer:
Step-by-step explanation:
Simplifying
2x + 13 = 0
Reorder the terms:
13 + 2x = 0
Solving
13 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 2x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 2x = 0 + -13
2x = 0 + -13
Combine like terms: 0 + -13 = -13
2x = -13
Divide each side by '2'.
x = -6.5
Simplifying
x = -6.5

Functions can be represented using equations and graphs Both f(x) and g(x) include domain values of [4, ∞) and range values of [0, ∞), and both functions have a y-intercept in common.
How to determine the key features?The domain of the function is defined as the set of the numbers we are allowed to put in the function while the range is the assumed data put in the function.
The functions are given as:
[tex]F(x)=e^{-x}\\\\\\g(x)=-\sqrt{x-4}[/tex]
Using a graphing calculator:
The domain of g(x) is [4, ∞)
The range of g(x) is [0, ∞)
The domain of f(x) is (–∞, ∞),
The range of f(x) is [0, ∞)
Both functions have positive values for their domains

The coordinates of parallelogram UVWZ are U(a, 0), W(c-a, b), and Z(c,0). Find the coordinates of V without using any new variables
A• (0, b)
B• (c, b)
C• (a, b)
D• (b, 0)
Answers
Answer: Choice A.
(0, b)
==================================================
Explanation:
Pick any random 3 numbers you want for a,b,c.
a = 1b = 2c = 3The points U, W and Z become
U = (a,0) = (1,0)W = (c-a, b) = (3-1, 2) = (2,2)Z = (c, 0) = (3, 0)Or in short,
U = (1,0)W = (2,2)Z = (3, 0)Plot each of those points on the same xy grid.
Next, using a different color, plot each of the answer choices.
A is at (0,b) = (0, 2)B is at (c,b) = (3,2)C is at (a,b) = (1,2)D is at (b,0) = (2,0)You should find that point A helps form a parallelogram, while the other answer choices don't lead to a parallelogram.

solve the system of equatioins 2x+3y=40 and -2x+2y=20
Answers
Answer:
x = 2 ; y = 12
Step-by-step explanation:
2x + 3y = 40
+ -2x +2y = 20
You solve for one of the variables by cancelling out one and making one the subject.
2x + 3y = 40.
+ -2x +2y = 20
5y = 60
5y/5 = 60/5
y = 12
Next, you solve for X by replacing the value of y in any of the equations.
2x + 3y = 40
2x + 3(12) = 40
2x + 36 = 40
2x = 40 - 36
2x = 4
2x/2 = 4/2
x = 2
To prove the equations are set, replace the values of X and Y in one of the equations.
2x + 3y = 40
2(2) + 3(12) = 40
4 + 36 = 40
40 = 40

What is mid point?A midpoint is a point in the middle of the line connecting two points that lies between them. The midpoint is a point that lies in the middle of the line and is equidistant from the two points if a line is drawn to connect them.
The midpoint between two points whose coordinates are known to us can be found using the midpoint formula. If we know the coordinates of the other endpoint and the midpoint, we can also use the midpoint formula to determine the coordinates of the endpoint.
Given coordinates
A(-3a, -2b), D(a, -2b), C(5a, -2b) and B(3a, 2b)
to find the coordinates of E,
and E is midpoint of B and C
for coordinates of midpoint is (x, y) = [(x₂ + x₁)/2, (y₂ + y₁)/2]
here B = (3a, 2b) = (x₁, y₁)
and C = (5a, -2b) = (x₂, y₂)
x = (5a + 3a)/2 = 8a/2 = 4a
y = (-2b + 2b)/2 = 0/2 = 0
E(4a, 0)
Hence coordinates of E are (4a, 0).

What is the length of side AB of parallelogram ABCD?

Answers
Answer:
8 units
Step-by-step explanation:
» Concepts
Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.
» Application
In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.
» Solving
Step 1: Subtract q from both sides.
[tex]4q-8-q=q+4-q[/tex] [tex]3q-8=4[/tex]Step 2: Add 8 to both sides.
[tex]3q-8+8=4+8[/tex] [tex]3q=12[/tex]Step 3: Divide both sides by 3.
[tex]3q/3 = 12/3[/tex] [tex]q=4[/tex]Step 4: Plug in the value of q for side AB.
[tex]4(4)-8[/tex] [tex]16-8[/tex] [tex]8[/tex]Therefore, the answer is 8 units.

after how many hours of work will mary ann and carlos have saved the same amount?
Answers
Answer:

Use a couple of ordered pairs on the graph and get the equation of the line:
(0, 2), (1, 10)The y-intercept is 2 and the slope is 10 - 2 = 8
The line is
y = 8x + 2Solve the system of equations by substitution to find the intersection
y = 6x + 10y = 8x + 26x + 10 = 8x + 28x - 6x = 10 - 22x = 8x = 4They will work 4 hours to get same amount of saving
Answer:
4 hours
Step-by-step explanation:
First, create a linear equation for Carlos using the graph.
Two points on the line: (0, 2) and (1, 10)
[tex]\implies \sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{10-2}{1-0}=8[/tex]
Use the point-slope equation with the found slope and one of the points:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-2=8(x-0)[/tex]
[tex]\implies y=8x+2[/tex]
Now equate the equations for Mary Ann and Carlos, and solve for x:
[tex]\implies 6x+10=8x+2[/tex]
[tex]\implies 8=2x[/tex]
[tex]\implies x=4[/tex]
Therefore, Mary Ann and Carlos have saved the same amount after 4 hours work.
