Answer:

C. 60°

Step-by-step explanation:

The angles in a triangle add up to 180°.

You are given 60° and 60°.

Add them

60 + 60 = 120

Subtract 120 from 180.

180 - 120 = 60°

Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train
ratelena [41]
Recall your d  = rt, distance = rate * time

so, keeping in mind that both trains are going at the same speed, say speed of "r" mph, after 212 hours A arrived at station A and after 4 hours, B arrived at station B.

now, the distance covered by train A is say "d", we know both stations are 585 miles apart, so, if train A covered "d" miles in those 212 hours, then train B covered the slack from 585 and d, that is "585 - d".

\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
\textit{Train A}&d&r&212\\
\textit{Train B}&585 - d&r&4
\end{array}
\\\\\\
\begin{cases}
\boxed{d}=212r\\
585-d=4r\\
----------\\
585-\boxed{212r}=4r
\end{cases}
\\\\\\
585=216r\implies \cfrac{585}{216}=r\implies \cfrac{65}{24}=r\implies \stackrel{mph}{2\frac{17}{24}}=r

Plsssss help me!!! Find the y-intercept of the rational function. A rational function is graphed in the first quadrant, and in t
SSSSS [86.1K]

Answer:

The y-intercept is (0,-2)

Step-by-step explanation:

we know that

The <u><em>x-intercept</em></u> is the value of x when the value of y is equal to zero

The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero

In this problem we have that

The graph crosses the x axis at negative 10 and crosses the y axis at negative 2.

therefore

The x-intercept is the point (-10,0) and the y-intercept is the point (0,-2)
