The value of n in the expression is,
⇒ n = - 3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Expression is,
⇒ 11(n − 1) + 35 = 3n
Now, We can simplify as;
⇒ 11(n − 1) + 35 = 3n
⇒ 11n - 11 + 35 = 3n
⇒ 11n - 3n = - 24
⇒ 8n = - 24
⇒ n = - 3
Thus, The value of n in the expression is,
⇒ n = - 3

find equation of the line shown
Answer:
[tex]\huge\boxed{y=-x+9}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
From the graph we have the y-intercept (0, 9) → b = 9.
Substitute it to the equation of a line:
[tex]y=mx+9[/tex]
From the graph we have the x-intercept (9, 0) → x = 9, y = 0.
Substitute to the equation:
[tex]0=9m+9[/tex] subtract 9 from both sides
[tex]-9=9m[/tex] divide both sides by 9
[tex]-1=m\to m=-1[/tex]
Finally:
[tex]y=-1x+9[/tex]

If the endpoints of segment AB are A(-4,5) and B(2,-5),
please help!
Answer:
[tex]d = \sqrt[2]{34}[/tex]
Step-by-step explanation:
We are solving for the segment of AB. Note that it is a line segment, so there will be end points, those being A(-4, 5) & B(2, -5).
Use the following distance formula:
[tex]distance[/tex] [tex](d) =[/tex] [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - x_{2})^2 }[/tex]
Let:
Point B(2 , -5) = (x₁ , y₁)
Point A(-4 , 5) = (x₂ , y₂)
Plug in the corresponding numbers to the corresponding variables.
[tex]d =[/tex] [tex]\sqrt{(-4 - 2)^{2} + (5 - (-5))^{2} }[/tex]
Simplify. Remember to follow PEMDAS. First, solve the parenthesis, then the powers, then add, and then finally square root.
[tex]d = \sqrt{(-6)^{2} + (5 + 5)^{2} } \\d = \sqrt{(-6 * -6) + (10)^2} \\d = \sqrt{(36) + (10 * 10)} \\d = \sqrt{36 + (100)} \\d = \sqrt{136}[/tex]
Simplify:
[tex]d = \sqrt{136} = \sqrt{2 * 2 * 2 * 17} = \sqrt[2]{17 * 2} = \sqrt[2]{34}[/tex]
[tex]d = \sqrt[2]{34}[/tex] is your answer.

Kendra took out a loan for $8,000 for 3 years with a compound interest rate of 1.75%. How much will she owe
Answer:
She will owe approximately $8,427.40 after three years.
Step-by-step explanation:
The compound interest formula is
A = P(1 + r/n)^(nt)
where A is the final amount; P is the principal, or initial, amount; r is the interest rate, as a decimal; n is the number of times the interest is applied per year; and t is the amount of time, in years.
By substituting the values in and assuming that the interest is compounded every year, we get:
A = 8,000(1 + 0.0175)^((1)(3))
8,000(1.0175)^3
8,000(1.05342411)
8,427.40.

Given: g(z)=5z+2.1
1. What is the value of g(z) if z= -4?
2. What is the value of g(z) if z= -7?
3. What is g(-8)?
Answer/Step-by-step explanation:
Given the function, [tex] g(z) = 5z + 2.1 [/tex], the table can be completed by substituting the given value of z as follows:
Question 2: z = -7
[tex] g(-7) = 5(-7) + 2.1 [/tex]
[tex] g(-7) = -35 + 2.1 [/tex]
[tex] g(-7) = 32.9 [/tex]
Question 3: z = -8
[tex] g(-7) = 5(-8) + 2.1 [/tex]
[tex] g(-7) = -40 + 2.1 [/tex]
[tex] g(-7) = 37.9 [/tex]
If r = 5 units and h = 7 units, what is the volume of the cylinder shown above? Use 3.14 for .
Answer:
549.5
Step-by-step explanation:
The formula for the Volume of a right cylinder is V= π r² h. First you are going to substitute the 5 with the r and the 7 with the h. V= (3.14)5²(7). 5²= 25.
3.14 (25)=78.5
78.5 (7)=549.5
Answer is 549.5

Answer:
x=36
Step-by-step explanation:
-4(-x-1)+2x+3=43

or, 4x+2x+4+3=43( arranging the like terms)
or, 6x+7=43( adding both numbers)
or, 6x=43-7(when there is + sign in one side if it will go to another side it will be -sign)
or, 6x=36(substracting the numbers)
or, x=36/6(when there is multiply in one side there will be divide)

The perimeter of a rectangle is 16cm. If the length is doubled, the perimeter is 26. What are the length and width of the rectangle? Please explain all steps required, thanks ahead of time!
Answer:
Length is 5, width is 3.
Step-by-step explanation:
The formula for the perimeter of a rectangle is:
[tex]P=2l+2w[/tex]
Where P is the perimeter, l is the length, and w is the width.
With the original length and width, the perimeter is 16, thus:
[tex]16=2l+2w[/tex]
Now, if we double the length, the 2l will become 4l. Also, the perimeter will change to 26. Thus:
[tex]26=4l+2w[/tex]
Now, we have a system of equations. We can solve it using elimination. Multiply everything by -1 in the first equation:
[tex]16=2l+2w\\-16=-2l-2w[/tex]
Now, add the equations:
[tex]-16=-2l-2w\\26=4l+2w[/tex]
-16 plus 26 is 10. -2l plus 4l is 2l. The 2w cancel. Thus:
[tex]10=2l[/tex]
Divide both sides by 2:
[tex]l=5[/tex]
So, the original length was 5.
To find the original width, substitute 5 back into the first equation:
[tex]16=2(5)+2w[/tex]
Multiply:
[tex]16=10+2w[/tex]
Subtract 10 from both sides:
[tex]2w=6[/tex]
Divide both sides by 2:
[tex]w=3[/tex]
So, the original width was 3.
And we're done!
Checking:
Originally, our length was 5 and 3. This means that the perimeter is 2(5+3)=2(8)=16 which is correct.
After we double our length, our length will be 10. This means that the new perimeter is 2(10+3)=2(13)=26. So, our answers are correct!
Let's assume that length be L and width be B.
Perimeter of rectangle is given by,
Perimeter = 2( L + B)
So,
⇒ 16 cm = 2 ( L + B )
⇒ 8cm = L + B _______( Say equation 1)
Now, we are given that when length is doubled perimeter is 26.
So,
⇒ 26 cm = 2 ( 2 L + B )
⇒ 13 cm = 2 L + B
⇒ 13 cm = L + L + B
Now use equation-1
⇒13 cm = L + 8cm
⇒13 cm - 8 cm = L
⇒5 cm = L
Therefore length is 5cm.
Now substitute this value in equation 1
⇒L + B = 8 cm
⇒5cm + B = 8 cm
⇒B = 8 cm - 5 cm
⇒B = 3 cm
Therefore breadth is 3 cm.
A line that is perpendicular to 3y=11-8x has slope m=
Step-by-step explanation:
for a perpendicular,
make x the subject.
8x=11-3y
x=11/8 +3/8
for a perpendicular, the gradient
x= -1/m
x= (-1/11/8) - (-1/3y/8)
x= 8/3y -8/11.
therefore the gradient (m) = 8/3y -8/11.
5 (t+3)=-3.5 solve for t
Answer:
t=-3.7
Step-by-step explanation:
5 (t+3)=-3.5
solving the bracket we have;
5t+15=-3.5
collect like terms
5t=-3.5-15
5t=-18.5
divide both sides by 5;
t=-3.7
The value of t in the given algebraic expression is; t = -2.3
We are given the equation;
5(t + 3) = 3.5
Using distributive property on the left hand side, we have;
5t + (5 × 3) = 3.5
5t + 15 = 3.5
Using subtractive property of equality, subtract 15 from both sides to get;
5t + 15 - 15 = 3.5 - 15
5t = -11.5
Divide both sides by 5 to get;
5t/5 = -11.5/5
t = -2.3

A vendor sells fifteen sweatshirts for $15 each, thirty t-shirts for $10 each, and forty hats for $8 each. What is the average price of an item sold that day?
I think the answer is 3$ because if you divide each item by the price you get 1 3 and 5 3 is more likely to be the middle so that would be your average price the unit rate of each of the items is dividing the price by the number of items to get the price of one item or your unit rate.
