X= 130 degrees since 180 is the total minus 50 from above
Answer:
2,000 miles
Step-by-step explanation:
We are given:

This can be rewritten as:

This is representative of a unit rate, as we have a
in the denominator. To calculate the number of miles in
inches, simply multiply the unit rate by
:


This can rewritten as:

Therefore, there are 2,000 miles in 4 inches.
-
We can check our solution by simplifying the fraction
by dividing both
and
by
to see if we achieve the unit rate:

Since this is in fact the unit rate, our solution is correct!
Answer:
I don't understand your question!!!
Answer:
t = 4 seconds
Step-by-step explanation:
The height of the projectile after it is launched is given by the function :

t is time in seconds
We need to find after how many seconds will the projectile land back on the ground. When it land, h(t)=0
So,

The above is a quadratic equation. It can be solved by the formula as follows :

Here, a = -16, b = 32 and c = 128

Neglecting negative value, the projectile will land after 4 seconds.

Then, y-4 = 5(x+2);
Finally, y-4 = 5x + 10 / +4
y = 5x + 14 ;
