I seem to be stuck on these few questions, could anyone help me?? ty

Brut [27]

Answer:

Step-by-step explanation:

1.)

we see that when x=0 y=0 which means that our equation

y=mx+b

b=0

(this is shown if we plug in 0 for x)

0= 0x+b

0=b

Next, we notice that each time it's increasing by four which means our slope is just 4

the answer is 4x

The y intercept (or b) is the same deal as question one

we can also see that when x=1 y=3 which means that

3=x+0

3=x

our slope is 3

How high is a tree that casts a 2222-ftft shadow at the same time a 44-ftft postpost casts a shadow which is 77-ftft long?

Zina [86]

Answer: The height of the tree is 12.57 ft.

Step-by-step explanation:

The height of a thing is proportional to the its shadow.

Let H = Height and S = length of shadow

Then by equation direct proportion , $\dfrac{H_1}{S_1}=\dfrac{H_2}{S_2}$ (i)

Given : A tree that casts a 22 ft shadow at the same time a 4 ft postpost casts a shadow which is 7-ft long.

Put $S_1=22 ,\ H_2= 4,\ \ S_2=7$ in (i), we get

$\dfrac{H_1}{22}=\dfrac{4}{7}\\\\ H_1=\dfrac{4}{7}\times22\approx12.57$

Hence, the height of the tree is 12.57 ft.
