Answer:
x > 9
Step-by-step explanation:
Simply solve for x.
What we have to do is subtract 3 from both sides, then divide by 5 to both sides.
5x > 45
x > 9
x is greater than 9.

The amount a basketball coach spends at a sporting goods store depends on the number of basketballs the coach buys. The situation is represented by the function rule a=16b.
A.) Make a table of values and graph the function rule. Is the graph continuous or discrete? Explain.
B.) Suppose the coach spent $128 before tax. How many basketballs did she buy?
Answer: 0,16,32,48,64
Step-by-step explanation: the equation 16b means you will multiple 16 by whatever is in the b box. For the first b is equal to 0 so 16x0 = 0, the second b is equal to 1 so 16x1 = 16
The discrete graph for the function rule is plotted and the coach will buy 8 basketballs for $128.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the amount which a basketball coach spends at a sporting goods store and it depends on the number of basketballs the coach buys. The situation is represented by the function rule a = 16b.
The given equation is -
a = 16b
where -
[a] represents the amount spend by the basketball coach.
[b] represents the number of basketballs buyed.
PART - AThe table is given as follows -
[b] [a]
0 0
1 16
2 32
3 48
4 64
The graph of the representing the function rule - a = 16b is attached with the answer. The graph is discrete as number of basketballs cannot exist in fractions. This means the possible values of [b] will be whole numbers only.
PART - B
If coach spent $128, then the number of footballs bought will be -
b = 128/16
b = 8
Number of footballs bought were 8.
Therefore, the discrete graph for the function rule is plotted and the coach will buy 8 basketballs for $128.

The length of a tarpaulin is 3ft. more than thrice its width and its area is 126ft². What is the length of the tarpaulin?
Answer:
Length = 22 ft
Width = 6 ft
Step-by-step explanation:
Let the width of the tarpaulin be x meters.
Therefore, length = 3x + 3
Area of tarpaulin = 126 ft²
[tex]x(3x + 3) = 126 \\ \\ 3x(x + 1) = 126 \\ \\ {x}^{2} + x = \frac{126}{3} \\ \\ {x}^{2} + x = 42 \\ \\ {x}^{2} + x - 42 = 0 \\ \\ {x}^{2} + 7x - 6x - 42 = 0 \\ \\ x(x + 7) - 6( {x + 7)} = 0 \\ \\ (x + 7)(x - 6) = 0 \\ \\ x + 7 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 7 \: \: or \: \: x = 6 \\ \\ \because \: x \: is \: side \: length \\ \therefore \: it \: can \: not \: be \: negative \\ \implies \: x \notin - 7 \\ \\ \implies \: x = 6 \\ \\ 3x + 3 = 3 \times 6 + 3 \\ \\ 3x + 3 = 18 + 3 \\ \\ 3x + 3 = 21 \\ \\ length \: of \:the \: tarpaulin \: = 21 \: ft \\ \\ width \: of \: the\: tarpaulin \: = 6 \: ft \\ [/tex]

7x-5=8(x*3) what value of x makes this equation true
The given equation is:
[tex]\displaystyle 7x-5=8(x+3)[/tex]
The first step you need to do is open the parentheses and distribute the 8 to x+3. It will be 8 times x and 3 times x.
[tex]8(x+3)=8 \times x+ 8 \times 3\\\\8 \times x=8x\\8 \times 3=24[/tex]
[tex]8(x+3) \rightarrow 8x+24[/tex]
Rewrite the equation:
[tex]7x-5=8x+24[/tex]
Now you need to move one of the variables to the other side.
If you move 7x to the other side, then:
You can move the variable by doing the opposite of it. Since 7x is positive, you can move it by subtracting 7x, which is negative. Subtract 7x on both sides:
[tex]7x-5-7x=8x+24-7x\\-5=x+24[/tex]
Now you need to leave x alone. x is being added to 24, so remove it by subtracting both sides by 24. Remember that when you're subtracting from a negative number, you're actually adding while keeping the negative sign.
[tex]-5-24=x+24-24[/tex]
Subtract:
[tex]\bf-29=x[/tex]
If you move 8x to the other side, then:
8x is positive, so you can move it by subtracting 8x, which is negative. Subtract 8x on both sides:
[tex]7x-5-8x=8x+24-8x\\-x-5=24[/tex]
You need to leave the variable alone, so move -5 to the other side. You can do this by adding 5 to both sides.
[tex]-x-5+5=24+5\\-x=29[/tex]
Lastly, x is negative, but you're looking for the value of positive x. Divide both sides by -1 to remove the negative sign.
[tex]\displaystyle \frac{-x}{-1} =\frac{29}{-1}[/tex]
Remember that a positive number divided by a negative number is negative. Divide:
[tex]\bf x=-29[/tex]
The answer to your question is x = -29.

Answer: x = -1
Step-by-step explanation: Insert all the numbers into x, and when you insert -1 to x, you get 40.
Answer:
x = - 1
Step-by-step explanation:
Given
- 4(3x - 7) = 40 ( divide both sides by - 4 )
3x - 7 = - 10 ( add 7 to both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1

Tracy is borrowing $10,700 on a six-year, %, add-on interest loan. What will Tracy's monthly payments be?
Answer:
Step-by-step explanation:
Use the formula I=prt. (Interest = principle x rate x time)
So, I = 10700 x 0.07 (7% as a decimal) x 6
So, I = 749(6)
I = 4494
Now, divide 4494 by 6(12)
4494/71
This = 63.3 dollars.
Therefore, she is paying 63 dollars per month.
Tracy's monthly payments is $62.41.
What is Simple Interest?The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.
Amount (A) = Principal (P) + Interest (I)
and, Simple Interest = PRT/100
Given:
P= 10700
Time= 6 year
Interest = 7%
Now, using simple interest
SI = P x R x T/100
SI = (10700 x 0.07 x 6)
SI = $4494
So, Tracy's yearly payments
= 4494/6
= 749
and, Tracy's monthly payments
= 749 / 12
= 62.41
Hence, Tracy's monthly payments is $62.41.

Write the equation of the line passing through the point (-2, 2) that is parallel to the line y = 2x + 3
Hi there! :)
[tex]\large\boxed{y = 2x + 6}[/tex]
A line that is parallel to y = 2x + 3 must have the same slope of 2. Therefore:
We can use the given point as well as the slope-intercept formula y = mx + b to solve.
Plug in the x-coordinate for "x" and y-coordinate of the point into "y":
2 = 2(-2) + b
2 = -4 + b
6 = b
Rewrite the equation:
y = 2x + 6

The Newtown Telephone Company advertises that if you use their 10-10 service, you will always pay only 9c per minute, no matter where you call within the country. Its major rival, Tryus Telephone Company, charges only 3c per minute, but you must pay a 36 c "connection fee" per call.
Create a cost equation for each telephone company where y is the total cost for each phone call (in cents), and x is the number of minutes the phone call lasts. Write a system of equations.
Answer:
y = 9x cents
y = (36 + 3x) cents
Step-by-step explanation:
Given that:
Newtown telephone company :
Fee per minute = 9c
Tyrus company :
Fee per minute = 3c
Connection fee = 36c
Cost equation :
y = total cost for each phone call:
x = minutes phone call last ;
Newton Company :
y = (fee per minute * minute phone call last)
y = 9 * x
y = 9x cents
Tyrus Company:
y = (connection fee + (fee per minute * minute phone call last))
y = (36 + (3 * x))
y = (36 + 3x) cents
Simplify the expression.
