The cost of sheet metal per square foot is $20.
What is a expression? What is a mathematical equation? What is Equation Modelling? What is the general equation of a straight line? What is the significance of slope of line?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. 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. The general equation of a straight line is -
y = mx + c
[m] is called slope and it tells the unit rate of change in [y] with respect to [x].
We have a contractor bought 10.8 ft² of sheet metal. He has used 2.3 ft² so far and has $170 worth of sheet metal remaining.
The equation 10.8x − 2.3x = 170 represents how much sheet metal is remaining and the cost of the remaining amount.
We have the following equation -
10.8x − 2.3x = 170
8.5x = 170
x = 170/8.5
x = 20
Therefore, the cost of sheet metal per square foot is $20.

Ezra works two summer jobs to save for a laptop that costs at least $1100. He charges $15/hr to mow lawns and $10/hr to walk dogs. This situation is modeled by: 15x + 10y ≥ 1100.
Suppose Ezra decides to also spend more than $80 on a printer. The inequality becomes
15x + 10y
.
The new inequality which represent Ezra's situation is 15x + 10y > 1180
How to write inequality?Cost of the laptop = at least $1100Amount Ezra charge to mow lawns per hour = $15Amount Ezra charge to walk dogs per hour = $10If
Hours spent to mow lawns = xHours spent to walk dogs = yThe inequality:
15x + 10y ≥ 1100
If Ezra decides to also spend more than $80 on a printer, that is, the amount spent on a printer is greater than $80
Adding an amount greater than $80 to the inequality,
It becomes 15x + 10y > 1180
Note the change in sign from greater than or equal to (≥) to greater than (>)
Therefore, the new inequality is given by 15x + 10y > 1180

Write a linear function f with f(-3)=1 and f(13)=5.
Answer:
0.25x+1.75
Step-by-step explanation:
A linear equation is of the form ax+b. Set a up a system of equation with -3 and 13 substituted in to ax+b. We get -3a+b=1 and 13a+b=5. Solving tis gives us a,b=(0.25,1.75)
Answer:
f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
a linear function has the form
f(x) = ax + b ( a and b have to be found )
given f(- 3) = 1 and f(13) = 5 , then by substitution
- 3a + b = 1 → (1)
13a + b = 5 → (2)
subtract (2) from (1) term by term to eliminate b
- 3a - 13a = 1 - 5
- 16a = - 4 ( divide both sides by - 16 )
a = [tex]\frac{-4}{-16}[/tex] = [tex]\frac{1}{4}[/tex]
substitute a = [tex]\frac{1}{4}[/tex] into (1) and solve for b
- 3( [tex]\frac{1}{4}[/tex] ) + b = 1
- [tex]\frac{3}{4}[/tex] + b = 1 ( add [tex]\frac{3}{4}[/tex] to both sides )
b = 1 [tex]\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]
f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex] ← is the linear function

a. Identity the independent and dependent variable.
b. After 10 days, how much money is left in your account.
The domain of the equation is 10 days and the range is the $14 left in the account.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
a) The independent variable in this problem is the number of days, represented as x. The amount of money left, the y variable is the dependent variable since it depends on the number of days left (x).
b) If there are 10 days left, we can plug it into the given equation to find the balance in the account.
y = -3x + 44
y = -3(10) + 44
y = -30 + 44
y = 14

On the coordinate plane, point F is located at (x, 8) and point G is located at (1, 4). The
distance between points F and G is √ √52 units.
What are the two possible locations of point F?
Answer:
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2} \\4^{2} +b^{2} = (\sqrt{52} )^{2} \\16 + b^{2} = 52\\b^{2} =36\\\sqrt{b^2} =\sqrt{36} \\b=6\\[/tex]
One of the possible x-values of point F will be 6 units to the right of point G. So, the x-value of point F could be 7, since 1+6=7. That means one possible location of point F is (7,8).
The other possible x-value of point F will be 6 units to the left of point G. So, the x-value of point F could be -5, since 1–6=–5. That means the other possible location of point F is (–5,8).
So the answer is:

The linear function that shows the proportional relationship between the distance and time is d = 100t
Linear FunctionA linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,
'm' is the slope of the line'b' is the y-intercept of the line'x' is the independent variable'y' (or f(x)) is the dependent variableFrom the table given, we can find the slope of the function by using the formula
m = y₂ - y₁ / x₂ - x₁
m = 300 - 200 / 3 - 2
m = 100
To find the y - intercept,
y = mx + c
300 = 100(3) + c
300 = 300 + c
c = 300 - 300

For the given quadratic equation we have:
a) F(-2) = 5
b) F(3) = 40
c) the solutions are:
t = -1
t = -1/3
How to evaluate the quadratic function?Here we have the following quadratic function:
F(t) = 3t^2 + 4t + 1
a) First, we want to determine the value of F(-2), to do so, we just need to replace the values of the variable, t, by the number -2, we will get:
F(-2) =3*(-2)^2 + 4*(-2) + 1
F(-2) = 3*4 - 8 + 1 = 5
F(-2) = 5
b) Now we want to find the value of the F(3), so this time we evaluate in x = 3.
F(3) =3*3^2 + 4*3 + 1
F(3) = 27 + 12 + 1 = 40
F(3) = 40
c) Last, we want to solve:
F(t) = 0
So we need to solve the quadratic equation:
3t^2 + 4t + 1 = 0
Using the quadratic formula we will get the two solutions:
[tex]t = \frac{-4 \pm \sqrt{4^2 - 4*3*1} }{2*3} \\\\t = \frac{-4 \pm 2}{6}[/tex]
Then the two solutions are:

The total surface of the Earth is 100% of the surface.
100% - 71% = 29%
29% of the surface is not covered with water.

What are the Properties of a Parallelogram?Some properties of parallelogram we need to recall in order to solve the problem given are:
They have two pair of sides that are parallel to each other and also of the same length.They have two diagonals that bisect each other into equal halves.1. q = 1x + 10
AC = 7x + 8
Therefore:
q = 1/2(AC) [based on the property of a parallelogram]
Substitute
x + 10 = 1/2(7x + 8)
Solve for x
2(x + 10) = 7x + 8
2x + 20 = 7x + 8
2x - 7x = -20 + 8

Anthony (30) will use the single filing status for 2021. His only income for the year was from wages. In early 2022, he received the following Form W-2 from his employer. He comes to you to have his taxes prepared, and he tells you he would like to contribute to a traditional IRA for 2021, but only if he is eligible to deduct the amount. He has no other adjustments to income. What is the largest amount Anthony can contribute and deduct if he makes the IRA contribution before the filing deadline? (Answer choices are below the image.)
Since Anthony is 30, the largest amount he can contribute and deduct from his Form W-2 for the traditional IRA for 2021 is $6,000.
What is the traditional IRA?The traditional IRA or individual retirement account is a pre-tax contribution an employee saves towards retirement.
With a traditional IRA, Anthony can contribute pre- or after-tax dollars, allowing his savings to grow tax-deferred while withdrawals are taxed as current income unless after the age of 59½.
An additional tax of 10% may apply if Anthony withdraws from his traditional IRA before reaching 59½ years.
However, one advantage of the traditional IRA is that the employee invests more funds upfront since the deduction is mostly made before tax.
Thus, I will advise Anthony to deduct a maximum of $6,000 from Form W-2 towards his traditional IRA to save more money in advance.
