Write the slope-intercept equation of a line parallel to y = 3x + 2 that

1 answer:

8 0

Parallel lines have the same slope, in this case 3.

To find the y intercept we plug in the points (2,1) into y=mx+b, with 2 being x and 1 being y.

1=3(2) + b
Solve this and you get -5 as the y intercept.

The equation is y=3x-5

Alyssa is building a brick mailbox. She is going to stack bricks that are each \dfrac23 \text{ft}

aalyn [17]

Given that each of the brick is $\frac{2}{3}$ ft tall and the finished stack of bricks is $4\frac{2}{3}$ ft tall.

Let the number of bricks in the stack be x, then

$\frac{2}{3} x=4 \frac{2}{3} = \frac{14}{3} \\ \\ \Rightarrow x= \frac{ \frac{14}{3} }{ \frac{2}{3} } = \frac{14}{3} \times \frac{3}{2} \\ \\ = \frac{14}{2} =7$

Therefore, 7 bricks will go in the stack.

Is the following relation a function? (6,2) (-2,2) (4,1) (-1,1)

yulyashka [42]

If each x term corresponds to exactly

one y term, the relation is a function.

In the data set shown here, notice that each x term, 6, -2, 4, and -1 appears only once. This means that each x term corresponds to exactly one y term. So yes, the relation is a function.

The album The Best of Radiohead, by Radiohead, has a list price of $13.83, and the album The King of Limbs, by Radiohead, has a

neonofarm [45]

Answer:

206 albums The King of Limbs and 34 albums The Best of Radiohead sold

Step-by-step explanation:

Let x be the no. of The album The Best of Radiohead sold .

We are given that total sales of both albums in one week is 240 albums.

So, number of albums The King of Limbs = 240 -x

Cost of 1 album The Best of Radiohead by Radiohead is $13.83

Cost of x album The Best of Radiohead by Radiohead = 13.83x

Cost of 1 album The King of Limbs, by Radiohead= $7.83

Cost of (240-x) album The King of Limbs, by Radiohead=7.83(240-x)

The total cost revenue of both albums in that week is 2083.20

So, 13.83x+7.83(240-x)=2083.20

13.83x+1879.2-7.83x=2083.20

13.83x-7.83x=2083.20-1879.2

6x=204

$x=\frac{204}{6}$

x=34

The no. of The album The Best of Radiohead sold is 34

Number of albums The King of Limbs = 240 -x =240-34=206

Hence 206 albums The King of Limbs and 34 albums The Best of Radiohead sold
