The graph of a line passes through the points (0, 5) and (-10, 0). What is the equation of the line?
natta225 [31]
First find the slope:
y-y/x-x
5-0/0-(-10
5/+10
slope: 1/2
then use:
y-5. 1
--- = ---
x-0. 2
cross multiply.
2 (y-5)=1 (x-0)
2y-10=x
move the ten to the other side, switch the sign
2y=x+10
divide by 2
y=1/2x+5
final answer is
y=1/2x+5

The measures of angles of a triangle are shown in the figure below solve for
irina1246 [14]

Answer:

x=51

Step-by-step explanation:

There are two ways you can go about this

You can either say that the sum of interior angles in a triangle is equal to 180 so you do 180-39-90=51

Or you could use the exterior angle theorem, which means that 90=39+x, simplify that and you get that x=51

3. A driver's path when diving off of a platform is given by h(t)=-5t^2+10t+20, where h(t) is the distance above water, in feet,
agasfer [191]

Answer:

3a.=20ft  3b.=1 second 3c.=3.25seconds

Step-by-step explanation:

Hello, Courtney!

h(t)=-5t^2+10t+20

20 would be the height so 3.a would be 20ft

3b.  25=-5t^2+10t+20

-5t^2+10t-5 then divide by greatest factor the answer would 1 second

3c.    0=-5t^2+10t+20 divide by greatest factor and would get 3.25 and -1.25 but can't have negative so the answer is 3.25.

I hope this helps

best you know who!
