Can you do c and d pla

Anna71 [15]

Answer:

c) y = - 2 x +3

d) y = 1/2 x + 1

Step-by-step explanation:

For c) Look for the exression that contains "3" as the y-intercept (the "b" in the form y = m x + b)

The only equation is y = - 2 x +3

For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.

The only equation that does such is y = 1/2 x + 1

S + 20= -14 3/5. ps: 3/5 means a fration like 3 over 5

GrogVix [38]

-14 3/5 -20= -34.6
you have to get the S alone so you move the 20 to the other side of the =. so S= -34.6

I have no idea how to even begin with this

We have two similar triangles, the one as a whole and the one inside of it. To calculate the height of the flagpole we can set up a proportion. First calculate the length of the base of the smaller triangle.

16.60 - 12.45 = 4.15m

The height is 1.65m, set up a proportion:

$\sf\dfrac{1.65}{4.15}=\dfrac{x}{16.60}$

Cross multiply:

$\sf 27.39=4.15x$

Divide 4.15 to both sides:

$\sf x=\boxed{\sf 6.6m}$

So the height of the flagpole is 6.6 meters tall.
