Mathematics

In order to find which one is or isn't, you need to solve for the value of 'x'. 
2x + 15 = 35 
2x = 20
x = 10 

Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,

Answer is B
Double check this. Chur! :)

Hope this makes sense.

hoa [83]

Answer:

third option

Step-by-step explanation:

time ('x') is the independent variable so that leaves only options 1 and 3 as the answer

is the slope equal to 0.6 or 1.8?

I used the slope formula with the following points:  (1,2) and (5,9)

(9-2) / (5-1) = 7/4 = 1.75, or 1.8

Anettt [7]

Answer:

Yes, your answers are correct.

The volume of a cone is given by V = 1/3πr²h.  Since the diameter of the first cone is 4, the radius is 2; therefore the volume is

V = 1/3π(2²)(8) = 32π/3

We divide the volume of the sink, 2000π/3, by the volume of the cone:

2000π/3 ÷ 32π/3 = 2000π/3 × 3/32π = 6000π/96π = 62.5 ≈ 63.

The diameter of the second conical cup is 8, so the radius is 4.  The volume then is:

V = 1/3π(4²)(8) = 128π/3

Dividing the volume of the sink, 2000π/3, by 128π/3:

2000π/3 ÷ 128π/3 = 2000π/3 × 3/128π = 6000π/384π = 15.625 ≈ 16

Evaluate the algebraic expression for the value given: -3x + X +9;=2*8)1
Strike441 [17]

y =-3x + x + 9

Find y when x = 2

Substitute the value of x= 2 into the equation

y = -3(2) + 2 + 9

y = - 6 + 2 + 9

y = -4 + 9

y = 5

The answer is 5

A = {1, 2, 5, 7}<br> B = {3, 4, 6, 7}<br> C = {0, 5, 8, 9}<br> Find A U B U C.
castortr0y [4]

Answer:  In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other.

A U B U C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Step-by-step explanation:

A = {1, 2, 5, 7}

B = {3, 4, 6, 7}

C = {0, 5, 8, 9}

A U B U C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }
