Answer:

r=0

Step-by-step explanation:

28=4r+28

Subtract 28 from both sides, you get

4r=0

so, 0/4 is 0, and r=0

Answer:

r is 7

Step-by-step explanation:

because if you do the math you will see r is 7

Answer:

The diamond production is 2006 is expected to be 13.24 billion

Step-by-step explanation:

Here, we want to predict the diamond production is 2006

The equation to use is given in the question as;

f(x) = 0.39x + 10.9

Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6

So f(6) = 0.39(6) + 10.9

f(6) = 2.34 + 10.9

f(6) = 13.24 billion

Step-by-step explanation:

Answer: y = 4/3 + 1/4x

Step-by-step explanation: 6y - 1.5x = 8

Add 1.5x to get y alone, 6y = 8 + 1.5x

Divide everything by 6, y = 8/6 + 1.5x/6

Simplify, y = 4/3 + 1/4x

I have no clue, working on same problem.

Answer:

c(10)=40

c(15)=52.5

Step-by-step explanation:

c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40

The value of c(10) and c(15) is 40 and 65 respectively.

The given function is c(x) = 2.5x + 15.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Now, c(10)=2.5(10)+15=40

c(15)=2.5(15)+15=52.5

Given c(20) = 65

So, 65=2.5x+15

⇒50=2.5x

⇒x=20

Therefore, the value of c(10) and c(15) is 40 and 65 respectively.

Answer:

£90

Step-by-step explanation:

Total money=£1100

Cost of new tv=£530

Mortage payment=£480

Therefore total money left =1100-(530+480)

=1100-1010=£90

The Proportionality Constant is used to compare values that are proportional.

When two variables are proportional to each other , change in one cause the change in the other .

There are two types of proportion, Direct and Indirect.

When on increasing one variable the other increases and vice versa it is called direct proportion .

When on increasing one variable the other decreases and vice versa it is called indirect proportion .

Answer: There are 16 quarters and 10 dimes.

Step-by-step explanation:

Let x = Number of quarters

y= Number of dimes.

As per given,

x+y = 26  (i)

x= y+6  (ii), substitute this in (i), we get

y+6+y= 26

⇒2y+6=26

⇒ 2y = 26-6=20

⇒ 2y =20

⇒ y =10   [Divide both sides by 2]

Put this in (ii),  x= 10+6 =16

So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .

Answer:

The correct option is;

Triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime 1 comma negative 1, B prime negative 1 comma 1, and C prime negative 1 comma negative 3

Step-by-step explanation:

The given parameters are;

The equation of the line t over which ΔABC is reflected is given by y = x

The coordinates of the vertices of ΔABC are given as follows;

A(-1, 1), B(1, -1), and C(-3, -1)

The reflection of a preimage (x, y) across the line y = x gives an image with coordinates at (y,  x)

Therefore, the coordinates of the vertices of the image ΔA'B'C' after the reflection of the preimage ΔABC over the line, y = x are given as follows;

Coordinates of preimage → Reflection across y = x → Coordinates of image

A(-1, 1) [tex]{}[/tex]                       Reflection across the line y = x          A'(1, -1)

B(1, -1) [tex]{}[/tex]                       Reflection across the line y = x          B'(-1, 1)

C(-3, -1) [tex]{}[/tex]                     Reflection across the line y = x          C'(-1, -3)

Therefore, the correct option is triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime 1 comma negative 1, B prime negative 1 comma 1, and C prime negative 1 comma negative 3.

Answer:

x = 8.5

Step-by-step explanation:

I got this answer by assuming the triangles were congurent, if they are not, the answer may vary.  

first, make an equation:

x + 8 = 3x - 9

bring 3x to the other side, by subtracting it

-2x + 8 = -9

Subtract 8

-2x = -17

divide by -2

x = 8.5

Then, just sub x into the formulas
