Answer:
Each t-shirt cost 13 dollars.
Step-by-step explanation:
Since the jacket was 20 bucks, we can set that aside:
85-20=65
Now that we've set that aside, there are five t-shirts. If they all cost the same, that means we can divide!
65/5=13
How to check?
Use inverse operations: 13*5=65
Re-add the 20 bucks from the jacket, and the bill is complete again! Use inverse operations: 13*5=65
Each shirt costs $13.
im stuck on this problem. can someone please help me.
The graph looks like an absolute function.
If we were to compare the function [tex]y= |x|[/tex] to this graph (see image attached), we see that the function in the graph has only shifted two to the right.
To write in function form, when shifting the graph horizontally
add within the function --> move the graph to the leftsubtract from within function --> move the graph to the rightIn this case, since we want to shift over two spots horizontally, we get the function is
y = |x -2|
Now we want to find the function that is increasing and decreasing over the same interval.
The only function that looks the most similar is y = 4|x-2|.
The reason for that is because the y = 4|x-2| is just a stretched version of y= |x-2| meaning the point where it is increasing or decreasing should stay the same. Look at the second image I attached.
Hope it helps!

Answer:
35m
Step-by-step explanation:
The formula to find the volume of right circular cylinder is: V=πr^2*h
We know the following info:
V = 5390m^3
r = 7m
So the equation would be 5390 = 3.14*7^2*h
so h = 35m
Answer:
h ≈ 35.01m
Step-by-step explanation:
V=Лr²h
r =7m
v = 5390³
h= V / Лr²
h= 5390 / Л7²
=35.01409m
Which is the best statement of the angle-angle similarity theorem?
When the preimage of a triangle is a dilation of the image, the triangles are similar.
When triangles have two pairs of corresponding angles that are congruent, those triangles are similar.
When triangles have two pairs of corresponding angles that are congruent, the third pair of angles is also congruent.

1.) WHat are the real zeros of the function
y=x(x-2)(x+3)
2.) Find all of the solutions of the equation
x^3 -x^2 +5x - 5 = 0
Problem 1
Answer: The roots are x = 0, x = 2, x = -3
------------------
Explanation:
The term "root" is another way of saying "zeros of a function" or "x intercept".
To find the roots, set each factor equal to zero and solve for x.
x-2 = 0 solves to x = 2, while x+3 = 0 solves to x = -3
========================================================
Problem 2
Answer: Roots are x = 1, [tex]x = i\sqrt{5}[/tex] and [tex]x = -i\sqrt{5}[/tex]
------------------
Explanation:
Factor by grouping
x^3 - x^2 + 5x - 5 = 0
(x^3 - x^2) + (5x - 5) = 0
x^2(x - 1) + 5(x - 1) = 0
(x^2 + 5)(x - 1) = 0
x^2 + 5 = 0 solves to the roots [tex]x = i\sqrt{5}[/tex] and [tex]x = -i\sqrt{5}[/tex]
x-1 = 0 solves to x = 1
Note: [tex]i = \sqrt{-1}[/tex]
1) Wat are the real zeros of the function y=x(x-2)(x+3):
Answer: [tex]x_{1} = -3 ; x_{2} = 0; x_{3} =2[/tex]
To find the x-intercept, set y = 0:
x( x -2 ) ( x + 3) = 0
Apply the Zero Product Property:
x - 2 = 0 or x + 3 = 0
x = 2 or x = -3
Find the union of solutions:
x = 0 or x = 2 or x = -3
2) Find all of the solutions of the equation
x^3 -x^2 +5x - 5 = 0
Answer: x = 1 or no real solution
Apply grouping:
[tex](x^{3} -x^{2} ) + *(5x-5)=0[/tex]
Factor out common factor:
[tex]x^{2} (x-1) +5(x-1)=0[/tex]
Factor out --> [tex](x-1)(x^{2} +5) =0[/tex]
Apply zero product property:
[tex]x - 1 =0[/tex] or [tex]x^{2} +5 =0[/tex]
x - 1 = 0
Rearrange variables to the left side of the equation--> x=1 or no real solutions.

How can you be certain that the angles you have created form a square inside the circle?
Answer:
By Ensure that its angles are identical, and also ensure that circle's diameter is only smaller than the square because then the circle diameter multiplies the range by 2, so how you can find the formula of the radius over
The building process is as follows:
Circle diameter is plotted.
The method as described in the perfectly straight central axis of a portion is drawn by the bisector of the right angle of the radius.
It is also a circular pattern diameter.

Answer:
∠ ABC = 51°
Step-by-step explanation:
the inscribed angle ABC is half the measure of its intercepted arc AC , so
5x + 11 = [tex]\frac{1}{2}[/tex] (16x - 26) ← distribute parenthesis
5x + 11 = 8x - 13 ( subtract 8x from both sides )
- 3x + 11 = - 13 ( subtract 11 from both sides )
- 3x = - 24 ( divide both sides by - 3 )
x = 8
Then
∠ ABC = 5x + 11 = 5(8) + 11 = 40 + 11 = 51°

In a scientific study there are 7 guinea pigs, 4 of which are pregnant. If 3 are selected at random without replacement, find the probability that all are pregnant. Enter your answer as a fraction or a decimal rounded to 3 decimal places.
The chances of selecting a pregnant guinea pig involves probability
The probability that all are pregnant is 0.187
How to determine the probabilityProbabilities are used to determine the chances of events
From the question, 4 out of 7 guinea pigs are pregnant.
So, the probability that a selected guinea pig is pregnant is:
[tex]p = \frac 47[/tex]
The probability that all the selected 3 are pregnant is then calculated as:
[tex]p = \frac 47 * \frac 47 * \frac 47[/tex]
Evaluate the product
[tex]p = 0.187[/tex]
Hence, the probability that all are pregnant is 0.187

Answer:
One solution
(2,0) is the point
Step-by-step explanation:
If the graphs of the equations intersect, then there is one solution that is true for both equations.
When the lines intersect, the point of intersection is the only point that the two graphs have in common, so the coordinates of that point are the solution for the two variables used in the equations.
The point of intersection is (2,0), because that is the point that both lines intersect at.

Answer:
(-1,1)
Step-by-step explanation:
Answer:
(- 1, 1 )
Step-by-step explanation:
2x - 3y = - 5 → (1)
3x + y = - 2 → (2)
multiplying (2) by 3 and adding to (1) will eliminate y
9x + 3y = - 6 → (3)
add (1) and (3) term by term to eliminate y
11x + 0 = - 11
11x = - 11 ( divide both sides by 11 )
x = - 1
substitute x = - 1 into either of the 2 equations and solve for x
substituting into (2)
3(- 1) + y = - 2
- 3 + y = - 2 ( add 3 to both sides )
y = 1
solution is (- 1, 1 )
