Draw similar triangles on the graph to determine the slope
Please help me 8th grade
Answers
Answer:
I believe this is talking about the vertical, and horizontal lines that are drawn to connect the diagonal line(the line by itself); for the rise, and run; or change in y over change in x. This forms right(90 degree) triangles with the change in y being the vertical part, the change in x being the horizontal part, and the diagonal part being the slope to connect the start, and finishing point.
From observing the graph, you can tell that the x axis counts by 1/2 every unit, and that the y axis counts by 1 every unit.
Since the y goes down 1 every unit and to the right 1 every unit with an x axis that counts by 1/2, and a y axis that counts by 1:
slope = change in y / change in x = -1 × 1 / 1 × 1/2 = -1 / 1/2 = -2 [this is the slope]
down is negative, up is positive.

Which expression has both 8 and n as factors?
Answers
Answer:
8n
Step-by-step explanation:
8n is the factor of both 8 and n. in the following question.
Factor ⇒ If a number, that use to divide another number and we get zero as a remainder, the number is called the factor of another number.
In this question, 8n is divided by both 8 and n and also we get zero as a remainder.
Therefore, 8n is the factor of both 8 and n .
We have that the expression must have 8 and n as integer and variable of the expression
From the Question we are told that
both 8 and n are factors of an expression
It is important to note that for 8 and n to be factors of an expression it must be present in the expression or the expression must have 8 and n as integer and variable of the expression
e.g
x=8+n

Answer: (-3,5)
Step-by-step explanation:
(-2,-3) would not work because adding them together would sum -5 which is less than 5 but y is not greater than -2.
(0,4) would not work because 4 isn’t greater than 4.
(-3,5) would work because -3+5=2 which is less than 4.In addition, 5 (the y value) is greater than -2.
(1,4) is incorrect because 1+4=5 which is greater than 4.
In other words,

∠A is a supplement of ∠B , ∠A is a complement of ∠C, and m∠B=124∘. Find m∠B+m∠C.
Answers
Answer:
158 degrees
Step-by-step explanation:
Here, we want to find the sum of the two angles.
If A is a supplement of B, it means that adding A and B together will yield 180 degrees
Mathematically;
A + B = 180
A + 124 = 180
A = 180-124
A = 56
Also, A is a complement of C
This means that adding A to C yields 90
A + C = 90
C = 90- A = 90 -56 = 34
Thus B + C = 34 + 124 = 158

h(3) = -4
h(-3) = -16
Step-by-step explanation:
Step 1: Define
h(x) = 2x - 10
h(3) = x = 3
h(-3) = x = -3
Step 2: Substitute and Evaluate
h(3) = 2(3) - 10
h(3) = 6 - 10
h(3) = -4
h(-3) = 2(-3) - 10
h(-3) = -6 - 10
h(-3) = -16
Maria has a cube-shaped box that measures 9 inches along each edge. Can she fit 1,000 square-inch cubes inside the box? Explain.
Answers
Answer:
No, she cannot fit it into the box
Step-by-step explanation:
The way to know is this is simply find the total surface area of the cube. This helps to know the capacity of the cube.
From the question, the side length of the cube is 9 inches;
Mathematically, the area of a cube is 6l^2
Thus, the total surface area of the cube = 6 * 9 * 9 = 486 square inches
Seeing that what she is trying to fix is less than the total surface area, then we can say that she cannot fix 1,000 square-inch cubes inside the box

f(x) = x-1 will give you a graph of linear function also known as "line"
f(x) = -1 will give you the exact graph like the picture. It's the graph of constant function.
f(x) = 1 will give you a graph of constant function like f(x) = -1. However the graph passes (0,-1) , not (0,1)
f(x) = x+1 will give you a graph of linear function.
Linear Function doesn't give you either vertical or horizontal line except for constant one.

the intensity of the sound of the lawnmower
the intensity of the sound of the lawnmower compared to the intensity of sound that is barely audible
Answers
Answer:
c. Intensity of the lawnmower
Step-by-step explanation:
Given
[tex]90 = 10log(\frac{I}{I_o})[/tex]
Required
What does 90 represent
In sound, intensity I (db) is calculated as:
[tex]I\ (db) = 10log(\frac{I}{I_o})[/tex]
Comparing the general formula to the given expression, we have that:
[tex]I\ (db) = 90[/tex]
This implies that 90 represents the sound intensity of the lawnmower.

Juan started his bank account with a $100 deposit and put in $38 a week. What is the formula for calculating how much money is in his bank account?
Answers
Answer:
[tex]M=38w+100[/tex]
Step-by-step explanation:
We can model this as a linear equation where the money in his account is [tex]M[/tex], the initial deposit is [tex]d[/tex] and the # of weeks is [tex]w[/tex].
Then we set up equation as:
[tex]M = aw + d[/tex]
Where [tex]a[/tex] is how much money he puts in per week.
So putting in values we have:
[tex]M=38w+100[/tex]
Let J(x) = formula for calculating the amount of money Juan will have in the bank after a certain number of weeks.
J(x) = 100 + 38x
