Solving equations:
(a) 5x - 9 = 3x + 3 (b) x + 6 = 34 - x
(c) 6x - 8 = 2 - 5

Thankyou. ​

Answers

Answer 1

Answer:

a ) 5x - 9 = 3x + 3

5x - 3 = 3+9

2x = 12

x = 12/2

x = 6

b) x+6= 34-x

x+x = 34 - 6

2x = 28

x = 28 / 2

x = 14

c) 6x - 8 = 2 - 5

6x - 8 = - 3

6x = - 3 + 8

6x = 5

x = 5/6

Answer 2

Step-by-step explanation:

a. x=6

b. x=14

c. x=-0..0625

Which expression represents these words?
6 less than the quotient of 36 and 4
A. 36/4 - 6
B. 36/4 + 6
C. (36 - 4) - 6
D. (36 - 4) + 6

Answers

Answer:

A

Step-by-step explanation:

the quotient of 36 and 4 is 36 divided by 4

6 less than the quotient means subtract 6  from the quotient , then

[tex]\frac{36}{4}[/tex] - 6 ← represents the statement → A

quotient = dividing so C and D are out and it says less than meaning subtracting there for it would be A

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.

Answers

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

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.

Answers

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 + c

Slope, 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

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.

Answers

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.

(6,0)

Answers

Answer:

(2,3)

Step-by-step explanation:

(2)(2) + (3)(3) = 13

The correct options are (a) and (d).

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).

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.

Answers

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

Does this graph show a Function? Explain why.​

Answers

this isn’t a function because if you do the vertical line test it hits twice.

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
