Quality Ts produces T-shirts for a $30 design fee plus a $6 charge per shirt printed.
The function rule for this scenario can be written in slope-intercept form as: y = 6x + 30.
How to Write a Function Rule?A function rule can be written in slope-intercept form using the unit rate or slope (m), and the starting value/initial value or y-intercept (b). The values of m and b, when determined, are simply plugged into the equation, y = mx + b.
We are given that the design fee that is charged by the cloth designer is a fixed fee of $30. This means that the starting value or y-intercept (m) is 30.
From the problem, we are also given that the additional charge per shirt printed is $6, this also implies that the slope or unit rate (m) of the function is 6.
To write a function rule in slope-intercept form, substitute m = 6 and b = 30 into y = mx + b:
y = 6x + 30.
The function rule for the cost of t-shirt produced based on the number of shirts is expressed as: y = 6x + 30.

There are 18 jars of crunchy peanut butter.
What is the total number of jars of peanut
butter on the shelf?
Using ratio, the total number of peanut butter on the shelf is 144.
What is the ratio?An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the total amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.So, the ratio of creamy to crunchy peanut butter:
5:3If there are 18 jars of crunchy peanut butter, the total number of peanut butter will be:
5(18):3(18)90:54Total ⇒ 90 + 54 = 144
Therefore, using ratio, the total number of peanut butter on the shelf is 144.

The best package of beans to buy is 26 ounce costs $8.84
How to calculate the best package ?
The first step is to find the unit rate for each packages
package a
6= 1.96
1= x
cross multiply both sides
6x= 1.96
x= 1.96/6
x= 0.326

15= 4.80
1= x
cross multiply both sides
15x= 4.80
x= 4.80/15
x= 0.32

The weighted mean for three exams is 78.1%.
Define weighted mean.The weighted mean is a form of mean that is computed by averaging all the products after multiplying the weight (or probability) connected to a specific event or result by its connected quantitative outcome. The difference between the weighted arithmetic mean and a regular arithmetic mean is that certain data points contribute more to the final average than others, as opposed to all data points contributing equally. In mathematics, the average value of the data is determined using the weighted mean. When calculating the weighted mean, the average value can be determined by giving various weights to some of the individual variables.

Find the remainder for the quotient using either substitution or synthetic division.
x - 5 is a factor of the polynomial
f(x) = x^3 - x^2 - 17x - 15)
(The answer must include what the remainder value is and what it indicates.)
(x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15 as there is no remaider.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given a polynomial function f(x) = x³ - x² - 17x -15.
If (x - 5) is it's factor then f(5) = 0.
∴ f(x) = x³ - x² - 17x -15.
f(5) = 5³ - 5² - 17(5) - 15.
f(5) = 125 - 25 - 85 - 15.
f(5) = 0.
So, the remainder is zero hence (x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15.

1. V= 12.1
2. V= 8.67
3. V= 11
4. V= 10
If a body is moving in the horizontal axis with a velocity Vx= 6m/s and in the vertical axis Vy=8m/s, the magnitude of the velocity of the body V is 10
The given parameters are;
The velocity of the body relative to the horizontal axis, vₓ = 6 m/s
The velocity of the body relative to the vertical axis, = 8 m/s
Required;
The measure of the magnitude of the velocity of the moving body, v
The velocity of the body can be represented vectorially as follows;
v = 6·i + 8·j
|V| = [tex]\sqrt{Vx^{2} + Vy^{2} }[/tex]
|V| = [tex]\sqrt{6^{2} + 8^{2} }[/tex]
