While at a store, Jared decided to buy some
shirts for $3.29 each and a jacket for $19.50.
Jared's purchase was a total of $35.95. Write an
equation to find how many shirts Jared bought.
3.29s + 19.50 = [?]
Answer:
5
Step-by-step explanation:
35.95 - 19.50 = 16.45 ÷ 3.29 = 5
Match each transformation of function f to a feature of the transformed function.
By analyzing the parent function graph, we will see that:
1) m(x) = -f(x) ⇒ "function decreases as x increases"2) h(x) = f(x) + 2 ⇒ "asymptote of y = 2"3) j(x) = f(x + 2) ⇒ "y-intercept at (0, 4)"4) g(x) = 2*f(x) ⇒ "y-intercept at (0, 2)"What thing does each transformation?
Let's list each transformation and let's see which is the correct option for each one.
1) m(x) = -f(x).
This is a reflection over the x-axis, so, now the curve will open downwards. This means that now we have a decreasing function, so the correct option here is: "function decreases as x increases"
2) h(x) = f(x) + 2
This is a vertical translation of 2 units upwards. So it moves the whole graph 2 units upwards. Originally, you can see that in the left side we have an asymptote at y = 0, now that asymptote will be at y = 2.
So the correct option is: "asymptote of y = 2.
3) j(x) = f(x + 2)
This is a shift of 2 units to the left, notice that when we evaluate this in x = 0 we et:
j(0) = f(2) = 2^2 = 4
So the y-intercept os (0, 4).
4) g(x) = 2*f(x)
This is a vertical stretch of scale factor 2.
When we evaluate this in x = 0, we get:
g(0) = 2*f(1) = 2
So the y-intercept is at (0, 2).

Pls explain for brainliest and a like
1.step by step
2. correct answer
3. clearly explained
Answer:
x = 11
Step-by-step explanation:
[tex]x^{2}[/tex] = 121
This means that 'x' × 'x' = 121
To know the value of x, we need to find the root of 121.
[tex]\sqrt{121}[/tex] = 11
If u mutiply 11 x 11 , you get 121.
Thus, x = 11
Answer:
x = 11, -11
use the formula: [tex]\sf a^2 = b[/tex] ➳ [tex]\sf a = \sqrt{b}, \ a = -\sqrt{b}[/tex]
[tex]\hookrightarrow \sf x^2=121[/tex]
changing the sides, changes square ( ² ) to square root ( ±√ )
[tex]\hookrightarrow \sf x=\pm \sqrt{121}[/tex]
[tex]\hookrightarrow \sf x=\sqrt{121},\:x=-\sqrt{121}[/tex]
[tex]\hookrightarrow \sf x=11,\:x=-11[/tex]

What is the slope of the line that passes through the points (-8,-6) and (-8, 4)?
Write your answer in simplest form.
Answer:
Slope is undefined
Step-by-step explanation:
To find the slope, subtract the y's and put that on top of a fraction. Then subtract the x's and put that on the bottom of the fraction.
This works all the time for any two points.
Here, though, we find the top
4 - -6
= 4 + 6
= 10
10 would go on top.
But then, on the bottom we get
-8 - -8
= 0
We get zero. As you know, you CANNOT have zero on the bottom of a fraction.
For the slope calculation we get 10/0
The slope is undefined.
Also, if you graph these two points, it's a verticsl line. Vertical lines (up and down) have an undefined slope.

Type the correct answer in the box. Use numerals instead of words. Erika and Rita have added a 1-mile walk to their daily exercise schedule. The table lists the time each of them took to walk the 1-mile distance over the past five days. Erika’s Time (in minutes) Rita’s Time (in minutes) 20 21. 25 21. 5 24. 75 22. 75 23 23. 25 23 20. 25 20. 75 On average, it takes Erika about minute(s) per mile less than Rita.
Answer:
The answer is 1.2
Step-by-step explanation:
It takes Rita 22.75 on average, and it take Erika 21.55 to walk the mile on average.
21.55 + 1.2 = 22.75
therefore, it takes Erika 1.2 minutes per mile less than Rita.
On average, Erika is much slower than Rita by 1 minute.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Since, There are two sets of data: Erika's and Rita's.
Now, we have to find the average values for each of both and compare them.
We would assume that the order of the presentation of data points is alternating,
first for Erika followed by Rita.
Hence, To illustrate what I mean, let's say
in Day 1, Erika's time is 20 and Rita's time is 21.25.
In Day 2, Erika's time is 21.5 and Rita's is 24.75.
And so on and so forth.
So, We get;
Erika's average is,
= (20+21.5+22.75+23.25+20.25)/5
= 21.55
Rita's average is,
= (21.25+24.75+23+23+20.75)/5
= 22.55
Hence, On average, Erika is much slower than Rita by 1 minute.
