How do I solve for x
Answer:
1. x = 3
2. x = 8
3. x = 5
4. x = 8
Step-by-step explanation:
1. 18 = 6x
divide both sides by 6
x = 3
2. x + 7= 15
subtract 7 from both sides
x = 8
3. 2x - 2 = 8
add 2 to both sides
2x = 10
divide 10 by 2
x = 5
4. -1 + x = 7
add 1 to both sides
x = 8
What does a function and a non-function mean?
Answer:
A function is a relation between domain and range such that each value in the domain corresponds to only one value in the range. Relations that are not functions violate this definition. They feature at least one value in the domain that corresponds to two or more values in the range.
Step-by-step explanation:
A can of vegetables is 8 in. high and has a radius of 3 in. Find the volume of the can.
Answer:
226.08 in^2
Step-by-step explanation:
The formula for area of a circle is pi*r^2
3^2 = 9
9*3.14 = 28.26
The formula for volume of a cylinder is surface area times height
28.26*8=226.08
Can someone help pls?
Answer:
Step-by-step explanation:
Let the original width be x
Then the original length = x + 11
Area = x * (x + 11)
If you decrease each side by 7 you get
Area 1 = (x - 7)(x + 4)
So area - area1 =
x (x + 11) -98 = (x - 7)(x + 4) Remove the brackets
x^2 + 11x - 98 = x^2 - 7x + 4x - 28 Combine the like terms
x^2 + 11x - 98 = x^2 - 3x - 28 Add 98 to both sides
x^2 + 11x = x^2 - 3x + 70 Cancel the x^2
11x = -3x + 70 Add 3x to both sides
14x = 70 Divide by 14
x = 70 / 14
x = 5
=====================
Original conditions
Answer width = 5
Length = 16

If 4m + 1 = 7 then 4m = 6
1) Symmetric Property 2) Subtraction Property of Equality
3) Substitution Property 4) Transitive Property
Answer:
2) Subtraction Property of Equality Properties
General Formulas and Concepts:
Pre-Algebra
Addition Property of Equality - Adding on both sidesSubtraction Property of Equality - Subtracting on both sidesMultiplication Property of Equality - Multiplying on both sidesDivision Property of Equality - Dividing on both sidesTransitive Property - If a = b and b = c, then a = cSymmetric Property - If a = b then b = aStep-by-step explanation:
Step 1: Define
4m + 1 = 7 → 4m = 6
Step 2: Identify
We see that we subtracted on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

a savings account earns 8% interest each year, compounded quarterly (4 times a year). If a person invests $100 and makes no further deposits or withdrawals, what is the balance in the account after 3 years?
===========================================
Work Shown:
The given values are
P = 100 = amount deposited (principal)r = 0.08 = decimal form of the annual interest raten = 4 = compounding frequencyt = 3 = number of yearsWhich means,
A = P*(1+r/n)^(n*t) .... compound interest formula
A = 100*(1+0.08/4)^(4*3) .... plug in given values
A = 126.824179456254 ..... value is approximate
A = 126.82 ...... round to the nearest cent
The balance of the account after three years is $126.82
Answer:
124 dollars
Step-by-step explanation:
.08 times 100 equals 8
eight times three is twenty four
that is the simplest answer. if the question had any further interests it might of been 126 or even 125.97

D. 5x - y = -11
PLEASE HELP
ILL GIVE YOU BRAINIEST
Answer:
Option (B)
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line which passes through the points (1, 1) and (-4, 7) will be,
m = [tex]\frac{7-1}{-4-1}[/tex]
= [tex]-\frac{6}{5}[/tex]
By substituting the value of m in the equation,
y = [tex]-\frac{6}{5}x+b[/tex]
Since, this line passes through (1, 1),
1 = [tex]-\frac{6}{5}(1)+b[/tex]
b = [tex]1+\frac{6}{5}[/tex]
= [tex]\frac{11}{5}[/tex]
Therefore, equation will be,
[tex]y=-\frac{6}{5}x+\frac{11}{5}[/tex]
5y = -6x + 11
6x + 5y = 11
Option B is the answer.
