Find the ratio of y/x to determine if the table represents a proportional relationship:
Answer:
From the table, find the ratio between each value of y and its corresponding value of x. y/x = 1/5 = 1/5 y/x = 8/40 = 1/5 y/x = 13/65 = 1/5 So, the ratio between the values of y and and their corresponding values of x is constant. Hence, the relationship represented by the table given above is proportional.

solve the equation for y: y + 7 = 5/4 (x + 16)
To solve the equation for y, we need to get y by itself on one side of the equation.
The first step is to get rid of the fraction on the right side of the equation by multiplying both sides by 4:
4y + 28 = x + 16
Then, we need to move the x term to the left side of the equation by subtracting x from both sides:
4y + 28 - x = 16
Then, we need to move the constant term 28 to the left side of the equation by subtracting 28 from both sides:
4y - x = -12
Finally, we have the equation in the form y = (1/4)x - 3, so the solution for y is y = (1/4)x - 3
It is important to note that in this solution we have used the distributive property and followed the order of operations to get to the final result, if you don't follow this steps you might get a different result.
STEPS FOR SOLVING LINEAR EQUATIONy+7=45(x+16)Use the distributive property to multiply 45 by x+16.y+7=45x+20Swap sides so that all variable terms are on the left hand side.45x+20=y+7Subtract 20 from both sides.45x=y+7−20Subtract 20 from 7 to get −13.45x=y−13Divide both sides of the equation by 45, which is the same as multiplying both sides by the reciprocal of the fraction.4545x=45y−13Dividing by 45 undoes the multiplication by 45.x=45y−13Divide y−13 by 45 by multiplying y−13 by the reciprocal of 45.x=54y−52SOLVE FOR Yy=45x+13

A circle with radius labeled 23 yards
Find the area for the circle (use 3.14 for pi). Show your work. Round to the nearest tenth.
Answer:
The area of the circle that has a radius of 23 yards will be 1,661.06 square yards.
What is the area of the circle?
It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is 23 yards. Then the area of the circle is calculated as,
A = π x (23)²
Simplify the equation, then the area of the circle is calculated as,
A = π x (23)²
A = 3.14 x 529
A = 1,661.06 square yards
The area of the circle that has a radius of 23 yards will be 1,661.1 square yards.

Picture 2: which table could be a partial set of values for a linear function?
Picture 3: is this function linear or nonlinear?
Picture 4: select linear or nonlinear to correctly classify each function.
Picture 5: a function is represented by values in the table. The function represented in the table is linear or is not linear.
Answer:
1) Linear
2) Top left
3) Nonlinear
4) Nonlinear
5) Linear
Step-by-step explanation:
1
There is a constant rate of change of 3. As the y changes by 3, the x changes by 1
2
The constant rate of change is 2
3
No constant rate of change
4
nonlinear The [tex]x^{2}[/tex] tells us that it will not be linear

An irregular polygon is shown below:
The area of the irregular polygon is ____ square units.
Answer:
20 square units
Step-by-step explanation:
you can separate this irregular polygon into 2 rectangles:
Rectangle 1 (bigger): 3 Units X 4 Units = 12 square units
Rectangle 2 (smaller): 2 Units X 4 Units = 8 square units
Add the 2 areas: 12+8 square units = 20 square units
Answer:
20
Step-by-step explanation:
To get the area of this irregular polygon, we have to turn the irrelgular polygon into 2 shapes. (Imagine a line drawn from the corner/wall that separates the unit 1 and 4 units down the bottom of the shape. I don't rlly know how to explain it sorry).
First we calculate the first rectangle which is simple, you just have to multiply! 3x4= 12.
Then for the second one, we have to subtract. Basically, 8 units minus 4 units is equal to 4 units meaning that our lenght is four units. Then 3 units minus 1 unit is equal to 2 units which is our width. (i'm deeply sorry if I couldn't explain it the best) Now we just do 4x2=8.
Now we just add 12 and 8 which gives us 20!

Michael has a bag of marbles. The frequency of selecting each color is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5 Based on the given frequency, determine the experimental probability of selecting a black marble. 0.27 0.33 0.40 0.60
help asap if answer is correct and provided explanation i will give brainiest.
Reason:
6 black out of 4+6+5 = 15 total
6/15 = 0.40 is the experimental probability of selecting black.
Side note: The term "empirical probability" is the same as "experimental probability".
The experimental probability of selecting a black marble will be 0.40. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.
Number of favourable outcomes = 6
Number of samples = 4+6+5 = 15
Probability = Number of favourable outcomes / Number of samples
Probability = 6 / 15
Probability = 0.40
Therefore, the probability will be 0.40.
