Which choice is a correct equation for the graph shown below?
A y = 2x + 20
B. y = 3x + 1
C. y = 10x + 5
D. y = 15x + 35
Answer:
C
Step-by-step explanation:
y = mx +b The b is where the graph crosses the y axis. If you look a the graph it is crossing at 5. The m is the slope. It is the change in y over the change in x. If you start at 5 and go up10 and over 1, you will be on the line. So our slope is 10/1 which is just 10
Answer:

The pair of ratios that form a proportion is given by:
B) 5/15 and 4/12.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
A pair of ratios will form a proportion if the division of the denominator by the numerator is the same, hence:
15/5 = 3.12/4 = 3.The pair of ratios that form a proportion is given by:

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line as shown in the diagram attached below = rise/run = 3/5.
How to Find the Slope of a Line Using Rise and Run?The rise of a line over the run of a line would give us the slope of a line on a coordinate plane.
With the given line in the diagram, the image attached below shows the rise as represented by a red line while the run is represented by the blue line.
Therefore, we have:
Run = 10 units
Rise = 6 units
Slope (m) of the line = rise/run = 6/10
Simplify
Slope (m) of the line = 3/5
Therefore, the slope of the line as shown in the diagram attached below = rise/run = 3/5.

What are the area and perimeter of a polygon with vertices (1,-2) , (1,5) , (7,-2)?Let
A= (1,-2) ,
B=(1,5) ,
C=(7,-2)
Therefore, the equation for distance is mathematically given as
d=\sqrt {(x^2-x^1)^2+(y^2-y^1)^2}
Therefore For AB
[tex]d=\sqrt {(-2-1)^2+(5-1)^2}[/tex]
d=5
For BC

How does probability explain work?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.Basic probability is governed by three primary rules: the addition rule, the multiplication rule, and the complement rule.Since there is a 50% chance that the outcome will be heads, we can anticipate 50 heads. But when we actually test it, we may get 48 heads, 55 heads, or anything else at all, though it will typically be a figure close to 50.Based on the given conditions formulate = 28 + 5 * 4

two positive integers have a product of 176. one integer is 5 less than the other integer. which equation can be used to find the value of x, the greater integer? x2 5
x(x – 5) = 176 is the correct equation to find the greater integer.
As the question mentions, the greater integer is x. So, the smaller integer will be (x - 5). Also, we are informed that their product is 176.
Now, representing the given information as mathematical expression -
x(x – 5) = 176
On further multiplication on Left Hand Side, we get the equation -
x² - 5x = 176
Rewriting the equation -
x² - 5x - 176 = 0
Further solving the equation to validate it.
x² - 16x + 11x - 176 = 0
x (x - 16) + 11 (x - 16) = 0
(x - 16) (x + 11) = 0
x = 16, -11
As stated, the integers are positive. So, the value of x and hence greater integer is 16.
Value of small integer = 16 - 5
Value of small integer = 11
So, the two integers are 16 and 11. Their product is 176 hence, our formed equation is correct.
Therefore, the equation that can be used to find x is : x(x – 5) = 176.

Sheila wants to build a rectangular play space
for her dog. She has 100 feet of fencing and
she wants it to be 5 times as long as it is wide.
What dimensions should the play area be?
The dimensions of the rectangular play area should be: 41.5 x 8.3 feet.
What is a rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.Now,
Given:
Fencing available = 100 feetLength = 5 times the widthTo find: Length and Width.
Let the width of the rectangular play area be x.
Then, the length = 5x
According to the formula of perimeter of a rectangle,
100 = 2 (x + 5x)
=> 50 = 6x
=> x = 8.3 feet (Approx.)
That is the width of the play area = 8.3 feet
=> Length = 5(8.3) = 41.5 feet.
Hence, The dimensions of the rectangular play area should be: 41.5 x 8.3 feet.

Answer:
0.136
Step-by-step explanation:
If we want to find out how many times larger a number is, they need to have the same amount of exponents to make it easier.
We can move the decimal point in (8 * 10^-1) (which equals 0.8) by 1 to the right, so it's exponent is now 1, same as the (1.088 * 10^1). Now we can divide.
