Answer:
I believe it is 1, I might be wrong.
Step-by-step explanation:
Two points on the graph are (1,2) and (2,3)
The first set has variables of x1 and x2 the second has variables of y1 and y2.
The formula is y2 - y1/x2 - x1
Put in the values and you get 2 - 3/2-1.
You would get 1/1, which is equivalent to 1.

Step-by-step explanation:
Does anyone know the answer?
Answer:
A
Step-by-step explanation:
A and B are the only answer choices that give you imaginary number outputs
But because the function in the answer choices is a negation of the original function they give different outputs, thus a different range
Therefore A is the correct answer

Joshua is 1.45 meters tall. At 2 p.m., he measures the length of a tree's shadow to be 31.65 meters. He stands 26.2 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter .
Answer:
The height of the tree=8.42 m
Step-by-step explanation:
We are given that
Height of Joshua, h=1.45 m
Length of tree's shadow, L=31.65 m
Distance between tree and Joshua=26.2 m
We have to find the height of the tree.
BC=26.2 m
BD=31.65m
CD=BD-BC
CD=31.65-26.2=5.45 m
EC=1.45 m
All right triangles are similar .When two triangles are similar then the ratio of their corresponding sides are equal.
[tex]\triangle ABD\sim \triangle ECD[/tex]
[tex]\frac{AB}{EC}=\frac{BD}{CD}[/tex]
Substitute the values
[tex]\frac{AB}{1.45}=\frac{31.65}{5.45}[/tex]
[tex]AB=\frac{31.65\times 1.45}{5.45}[/tex]
[tex]AB=8.42m[/tex]
Hence, the height of the tree=8.42 m

The tens digit is missing from the three-digit number 8 _ 9. If the tens digit is to be randomly selected from the ten different digits from 0 to 9, what is the probability that the resulting three digit number will be a multiple of 9?
Step-by-step explanation:
Only 1 number works. 1 will make 819 which is divisible by 9.
Since it is 1 of ten numbers can go in the blank, the answer is 1/10 which is 0.1
The 10 number choices are
0,1,2,3,4,5,6,7,8,9
The only one that works is 1 as I've stated.
A man serves 6 customers in 30 minutes. How many customers can be served in 2 hours?
Answer:
24
Step-by-step explanation:
2 hours * 60 minutes/hour = 120 minutes
120 minutes / 30 minutes = 4
120 minutes is 4 times 30 minutes, so he can serve 4 times as many people.
4 * 6 customers = 24 customers
Answer: 24
A man serves 6 customers in 30 minutes. There are 24 customers who can be served in 2 hours.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
A man serves 6 customers in 30 minutes. we want to find how many customers can be served in 2 hours.
We know that
2 hours x 60 minutes/hour = 120 minutes
120 minutes / 30 minutes = 4
120 minutes is 4 times 30 minutes, so he can serve 4 times as many people.
= 4 x 6 customers
= 24 customers

Given a line segment that contains the points A,B, & C in order,if AB = 5x + 4, BC = 4x - 8, and AC = 23, find the length of segment AB.
Select one:
a. 23
b. 9
c. 19
d. 3
Answer:
C
Step-by-step explanation:
AB + BC = AC , that is
5x + 4 + 4x - 8 = 23
9x - 4 = 23 ( add 4 to both sides )
9x = 27 ( divide both sides by 9 )
x = 3
Then
AB = 5x + 4 = 5(3) + 4 = 15 + 4 = 19 → C
Find the average rate of change of g(x)=-2x^3-5 from x=-4 to x=1
Answer:
26
Step-by-step explanation:
We have the average rate of change on the interval [a,b] as
f(b)-f(a)/(b-a)
b = 1 and a = -4
f(b) = f(1) = -2(1)^3 -5 = -2-5 = -7
f(a) = f(-4) = -2(-4)^3 -5 = 128 -5 = 123
so we have;
(123 + 7)/(1+4) = 130/5 = 26

find the slope of the line 3x-5y =0
Answer:
slope= ⅗
Step-by-step explanation:
Rewrite the equation into the slope-intercept form, y=mx +c, where m is the gradient and c is the y-intercept.
3x- 5y= 0
+5y on both sides of the equation:
5y= 3x
Divide both sides by 5:
y= ⅗x
From the coefficient of x, the slope of the line is ⅗.
x + y = 3, 4y = -4x - 4
System of Equations
Answer:
no solutions
Step-by-step explanation:
Hi there!
We're given this system of equations:
x+y=3
4y=-4x-4
and we need to solve it (find the point where the lines intersect, as these are linear equations)
let's solve this system by substitution, where we will set one variable equal to an expression containing the other variable, substitute that expression to solve for the variable the expression contains, and then use the value of the solved variable to find the value of the first variable
we'll use the second equation (4y=-4x-4), as there is already only one variable on one side of the equation. Every number is multiplied by 4, so we'll divide both sides by 4
y=-x-1
now we have y set as an expression containing x
substitute -x-1 as y in x+y=3 to solve for x
x+-x-1=3
combine like terms
-1=3
This statement is untrue, meaning that the lines x+y=3 and 4y=-4x-4 won't intersect.
Therefore the answer is no solutions
Hope this helps! :)

4.2.4 practice: Modeling: Slope intercept equation of a line
Given:
Modeling: Slope intercept equation of a line
To find:
The slope intercept equation of a line.
Solution:
The slope intercept equation of a line is defined as:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
It means the line intersects the y-axis at (0,b).
For example: The slope of a line is 2 and its y-intercept is 1, then the slope intercept of the line is:
[tex]y=2x+1[/tex]
Therefore, the slope intercept form of a line is [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.

12 cm
Step-by-step explanation:
Given :-
A wire shaped to form a square of area81cm². An equilateral triangle was formed bythe same wire.To Find :-
The length of a side of the triangle formed?Solution :-
We know that the area of square is ,
> a² = 81 cm²
> a = √81 cm²
> a = ±9 cm
> a = 9cm ( -ve not possible )
Therefore perimeter ,
> P = 4a
> P = 4 * 9cm
> P = 36 cm .
We know all sides of ∆ are equal. therefore ,

can someone help me out?
Step-by-step explanation:
does this mean the sale price includes the tax already ?
then we need to find 13% of the original price before taxes.
that would be done by saying that $101.94 are actuality 113% of the original price (original price = 100%, and then 13% are added).
101.94 = 113%
1% = 101.94/113
13% = 101.94 × 13/113 ≈ $11.73
that means it of the total sales price of $101.94, $11.73 would be the included taxes.
but if this means that 101.94 = 100% of the original price before taxes, we need to calculate the 13% based on that
101.94 = 100%
1% = 101.94/100
13% = 101.94 × 13/100 ≈ $13.25
and then the total price to be paid is
101.94 + 13.25 = $115.19
