Answer:

Alrighty! So this is what we know:

Slope (m) = (-4)

Co-ordinate (0,3)

Co-ordinate 2 (6,t)

t = ?

Let's find our equation...

y=mx+b <-- just plug what we know in...

3=(-4)0+b

3=0+b

b=3

We just found b! woohoo

Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).

SO-

t=y

plug it in our equation...

y=mx+b

t=(-4)x+3

t=(-4)(6)+3

t=(-24)+3

t=(-21)

SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)

What is the largest three-digit number that is a multiple of both $24$ and $30$
irina [24]

We are given two numbers $24 and $30.

We need to find the largest three-digit number that is a multiple of both $24 and $30.

So, we need to find the largest common multiple of 24 and 30.

<em>In order to find the largest common multiple, we need to multiply both numbers.</em>

If we multiply 24 and 30, we would get

24 × 30 = 720.

Therefore, the largest three-digit number that is a multiple of both $24 and $30 is 720.

the population of collin county, which follows the exponential growth model, increased from 491,675 in 2000 to 782,341 in 2010.
CaHeK987 [17]

Applying the formula for the exponential growth model, the growth rate is  0.046447277776453351798354258063923

the exponential growth is a data pattern that illustrates an increase over time by generating an exponential function curve.

The exponential growth model can be expressed as:

P(t) = P(0) x e^(k.t)

Where:

P(t) = Value at time t

P(0) = Initial value

k = growth rate

Information from the problem:

P(0) = 491,675

P(t) = 782,341

t = 2010 - 2000 = 10 years

Substitute the data into the formula:

782,341 = 491,675 x e^{10k}

e^{10k} = 782,341 / 491,675

10 k . ln e = ln (782,341 / 491,675)

10 k = 0.46447277776453351798354258063923

k = 0.046447277776453351798354258063923

The width of a rectangle is 8 cm less than its length. The perimeter of the rectangle is 52 cm. What is the width of the rectang
ozzi
L = X
w = X - 8
P = 52 cm

P = 2l + 2w
52 = 2(X) + 2(X - 8)
52 = 2x + 2x - 16
52 + 16 = 4x
68 = 4x
68/4 = 4x/4
17 = X.

The length of the rectangle is 17 cm.

W = X - 8
W = 17 - 8
W = 9 cm.

The width of the rectangle is 9 cm.
