Step-by-step explanation:
we need to do inverse operations
6 + 6 = 12
12 divided by 4 = 3
e = 3
Check:
4(3) - 6 = 6
Answer:
e = 3
Step-by-step explanation:
The first step in solving an equation that has a variable is to isolate it. The variable is the unknown number and it is usually what you are trying to find the value of (x is the sign most used to represent a variable).
In order to isolate the variable in the equation 4e - 6 = 6, add 6 to both sides of the = sign:
4e - 6 = 6
+ 6 = + 6
4e - 6 + 6 = 6 + 6
We add 6 because doing so will cancel out the -6, leaving only e.
4e = 12
Now, because the question is asking for the value of e and not 4e, the next step is to divide both sides by 4:
[tex]\frac{4e}{4}[/tex] = [tex]\frac{12}{4}[/tex]
After dividing, the equation is shown as e = 3, which would be your answer.

12. A scatter plot of data showing the percentage of total Internet users who
visited an online store on a given day in December includes the points
(2008, 2.0) and (2010, 4.5). Write the slope-intercept form of an equation
for the line of fit containing those points.
Using the slope - intercept relation, the equation of the line is y = 1.25x - 2508
The slope - intercept form of the equation can be obtained thus :
General form ; y = bx + cSlope, b = (y2 - y1) ÷ (x2 - x1)
Slope, b = (4.5 - 2.0) ÷ (2010 - 2008)
Slope = 2.5 / 2 = 1.25
Using any of the pair of points we can obtain the intercept thus :
2 = 1.25(2008) + c
2 = 2510 + c
2 - 2510 + c
c = - 2508.
Hence, the equation is y = 1.25x - 2508

The recipe serves 8 people, so to figure out how much you need to serve 32 people you multiply each measurment by 4 because 8 x 4=32.
2 1/4 x 4 = 9
2 x 4 = 8
3/4 x 4 = 3
1 x 4 = 4
2 x 4 = 8
Alan wants to make a metal cylinder (with length of 40 MM) melt down a solid metal sphere with a volume 36000mm^3
Show that the radius of the cylinder is equal to the radius of the sphere.
Answer:
Answers not possible?
Step-by-step explanation:
Sphere:
V = (4/3)πr³
Cylinder: V = πr²h
1. Calculate the radius of the sphere with volume of 36000 mm^3:
r = 20.5 mm
2. Calculate the volume of a cylinder with a radius of 20.5 mm and length of 40 mm.
V = 52810 mm^3
====
I don't see how the radius of the cylinder and sphere can be equal to each other, given the values provided.
I also note that the question asks for both the radius AND length of the sphere: A sphere does not have a length.
Sorry, but I don't see an answer to either of the questions, as written. Hopefully someone else will see a solution.

Does this graph show a Function? Explain why.
Answer:
A. No, the graph fails the vertical line test
Step-by-step explanation:
A function links two set in a way that for each element from the origin set (called domain) you get one and only one element of the target set (co-domain, or range). In layman terms, once you pick your x, you get a single y. In term of graphing it it means that a vertical line of equation touches the function either zero times (c is outside the domain, or only once (if c is in the domain.
That's the "vertical line test": you touch the graph twice, it's not a function. And since if you try the test with a vertical line between -4 and 4 you are getting two values (one above the x axis, one below it) it is not a function

Jessica has three fewer candies than twice the number Dante has.
a. If Dante has d candies, write an expression to represent how many candies Jessica has.
b. If Jessica has 19 candies, write and solve an equation to find out how many candies Dante has.
Answer:
j = 2d - 3
d = 11
Step-by-step explanation:
a. If Dante has d candies, write an expression to represent how many candies Jessica has.
j = 2d - 3
b. If Jessica has 19 candies, write and solve an equation to find out how many candies Dante has.
19 = 2d - 3
add 3 to both sides
22 = 2d
Divide both sides by 2
11 = d
d = 11
a) There are (2d - 3) candies Jessica has.
b) There are 35 candies Dante has.
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.
Given that;
Jessica has three fewer candies than twice the number Dante has.
a) Let number of candles Dante has = d
So, Number of candles Jessica has = 2d - 3
b) Here, number of candles Dante has = 19
So, Number of candles Jessica has = 2×19 - 3
= 35

rule: add 15, subtract 10. first term 4
what are the answers?
Answer:
4, 9, 14, 19, 24, 29, 34, 39, 44, 49 and so on.
Step-by-step explanation:
1. If we use the rule starting from 4, we can add 15. That will give us 19.
2. Subtract 10, that will give us 9.
Now if we keep applying this rule we will keep going on to an infinite possibility of numbers.
So, the next number would be 9, then so on.

An online furniture store sells chairs for $50 each and tables for $550 each. Every day, the store can ship a maximum of 32 pieces of furniture and must sell no less than $4100 worth of chairs and tables. If 24 chairs were sold, determine the minimum number of tables that the store must sell in order to meet the requirements. If there are no possible solutions, submit an empty answer.
Answer:
you have to sell 6 tables to meet all requirements
Step-by-step explanation:
chairs=$50x
tables=$550x
24 chairs×50= $1200
4100-1200= $2900
take $2900 and divide by $550 to find the exact number of tables which is 5 but selling 5 tables and 24 chairs doesnt reach the $4100 mark so I rounded up to 6 tables which doesnt surpass the maximum number of furniture(32) but beats the $4100 mark

What is a system of linear equations?A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
The given equation is as below,
2x + 3y = 12 (1)
In order to find the correct answer all the options are considered one by one as follows,
(a) (0, 4)
Substitute x = 0 and y = 4 in equation to get,
LHS = 2× 0 + 3 × 4
= 12
Since LHS = RHS, the given option is correct.
(b) (3, 2)
Substitute x = 3 and y = 2 in equation to get,
LHS = 2× 2 + 3 × 2
= 10
Since LHS ≠ RHS, the given option is not correct.
(c) (2, 3)
Substitute x = 2 and y = 3 in equation to get,
LHS = 2× 3 + 3 × 3
= 13
Since LHS ≠ RHS, the given option is not correct.
(d) (6, 0)
Substitute x = 0 and y = 4 in equation to get,
LHS = 2× 6 + 3 × 0
= 12
Since LHS = RHS, the given option is correct.
Hence, the points satisfying the given equation are (0, 4) and (6, 0).
