Answer:
The coach paid $69 on the three soccer balls
Step-by-step explanation:
If the coach bought 3 soccer balls for 26$, minus the $7 on each, plus the $4 tax on each, the expression would be:
3 × (26 - 7 + 4)
We put the addition and subtraction in parentheses because of PEMDAS. PEMDAS say we must solve for whatever is in the parentheses first, then exponents (there are none in the expression), ans then multiplication. If those numbers were not in parentheses, the answer would look completely different as we would multiply before subtracting and adding. We must find the total amount each ball cost first:
26 - 7 + 4 = 23
Each ball cost $23
If the coach bought 3 balls for $23 each, we have to multiply the two numbers:
3 × $23
$69

The equation of the line is 7x+2y = 1
What is an equation of a line?The equation of a line is linear in the variables x and y which represents the relation between the coordinates of every point (x, y) on the line. i.e., the equation of line is satisfied by all points on it.
Given that a line is passing through two points J(-3, 11) and K(1, -3). we need to find the equation of line JK,
So, we know that the equation of a line passing from two points (x₁, y₁) and (x₂, y₂) is =
y-y₁ = y₂-y₁/x₂-x₁ (x-x₁)
Here, (x₁, y₁) and (x₂, y₂) = J(-3, 11) and K(1, -3)
Therefore, the equation of the line =
y-11 = -3-11 / 1+3 (x+3)
y-11 = -7/2(x+3)
Multiply by 2,
2y-22 = -7(x+3)
2y-22 = -7x-21
7x+2y = 1
Hence the equation of the line is 7x+2y = 1

What is the domain for f(x) = 1/2(x + 1) + 3?
What is the domain for f(x) = 2?
What is the domain for f(x) = -2(x - 2) + 1?
Answer:
the domain of f(x) = 1/2(x + 1) + 3 on this graph is [-6,-1] because there are solid dots on -6 and -1
the domain of f(x)=2 on this graph is (-1,2] because there is an open circle on -1 and a solid circle on 2
the domain of f(x) = -2(x - 2) + 1 is (2,6] because there is an open dot on 2 and a solid circle on 6
The domain of the given all three functions are explained below.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
We must identify each value of the independent variable (often represented by x) for which the function is specified in order to establish the domain of the function.
A function's domain may be constrained by certain guidelines or limitations, such as:
The domain must be free of any x values that would result in the denominator being 0 since the function could contain a fraction with a denominator that cannot be zero.The domain must be free of any values of x that would turn the expression beneath the radical into a negative expression since the function could contain a square root of a negative number.From the graph, the domain of the given function is f(x) = 1/2(x + 1) + 3 is [-6, -3].
From the graph, the domain of the given function is f(x) = 2 is (-3, 2].
From the graph, the domain of the given function is f(x) = -2(x - 2) + 1 is (2, 6].

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibles?
( I need the answers, plus the steps please and thank youuu :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equation:
s = 10│x - 4│+ 50
Where s = sound level in decibels
x = number of measures of music played
Step 1:
Subtract 50 from Both sides
s - 50 = 10│x - 4│+ 50 - 50
s - 50 = 10│x - 4│
For s = 80
80 - 50 = 10│x - 4│
30 = 10│x - 4│
Clear the absolute value sign
± 30 = 10x - 40
Hence ;
Lower value :
- 30 + 40 = 10x
10 = 10x
x = 1
Upper value :
+30 + 40 = 10x
70 = 10x

Answer:
210
I am divisible by 5.
So your ones digit is 0 or 5
I am an even number.
So your ones digit is 0. We fill that in.
_ _ 0
My tens digit is 1.
So we fill that in.
_ 1 0
My tens digit is greater than my ones digit.
Well, of course 1 is greater than 0. We didn't need to be told that.
I have only one odd digit.
Since the 1 is odd, the hundreds digit is even, 2,4, or 8
I am less than 400.
So your hundreds digit is 2. Fill that in and we're done.
2 1 0
My hundreds digit is greater than my tens digit.
Of course 2 is greater than 1, we didn't need to be told that.
I am divisible by 3.
Of course 210 is divisible by 3. We didn't need to be told that.

Answer:
a = 60
60°, 60°, 120°, and 120°
Step-by-step explanation:
So we know that the sum of the angle measures of the quadrilateral is 360° and that the four angle measures are a, 2a, a, and 2a. This means that the sum of a, 2a, a, and 2a should equal 360.
a + 2a + a + 2a = 360
Combine like terms.
6a = 360
Divide both sides by 6.
a = 60
So the value of a would be 60.
Now to find the angle measures from least to greatest, we would have to find the values of a, 2a, a, and 2a.
a = 60
2a = 120
a = 60
2a = 120
So the angle measures from least to greatest is 60°, 60°, 120°, and 120°.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
a=60 degrees
Step-by-step explanation:
Total angle measurements=360 so
2a+2a+a+a=360
2(60)+2(60)=240
240+60+60=360
----------------------------
So a=60

. Eight years ago, Rudi thought that he was making a sound investment by buying $1000 worth of Pro Sports Management stock. Unfortunately, his investment depreciated steadily, losing 15% of its value each year. a. What is the multiplier? b. Write a function using f(t) to describe the situation. c. How much is the stock worth now?
Answer:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49
Step-by-step explanation:
Given that:
Initial investment made, 8 years ago = $1000
Depreciation value each year = 15%
To find:
a. Multiplier
b. Function [tex]f(t)[/tex] to describe the situation.
c. Worth of stock now.
Solution:
a. Depreciation of 15% means the value becomes (100 - 15) % = 85% or 0.85 of the actual value.
Therefore, the multiplier is 0.85.
b.
Every year the value becomes 0.85 times of the actual value.
If it continues for [tex]t[/tex] years, then the values will be:
[tex]f(t) =1000(0.85)^t[/tex]
c. Let us put [tex]t=8 \ years[/tex] to find the worth of stock now.
[tex]\Rightarrow f(8) =1000(0.85)^8\\\Rightarrow \bold{\$272.49}[/tex]
So, the answers are:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49
