50 degrees

All triangles have 180 degrees total.

Since it’s an isosceles triangle, the 2 bottom angles are congruent; thus, they have the same angle measurement.

Now just subtract the two angles from 180 to get the third angle.

180 - 65 - 65 = 50

Two trains leave towns 1250 km apart at the same time and travel toward each other. one train travels 10 km/hr slower than the o

Oksana_A [137]

Here are the rates of the trains:
(n represents train A's speed)
A: n
B: n + 10
We know it is 5 hours, and total distance, so:
5(n) + 5(n + 10) = 1250
5n + 5n + 50 = 1250
10n = 1200
Divide:
n = 120
One train goes 120, the other goes 130

Which functions have the same rate of change?

Alja [10]

Answer:

Option 3

Step-by-step explanation:

All equations are in slope-intercept form. $y=mx+b$

The 'm' is the slope.

The 'b' is the y-intercept.

The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.

<em>Let's look over the equations:</em>

<h3>Equation A:</h3>

$y=0.3x-6$

In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.

<h3>Equation B:</h3>

$y=3x-8$

In this equation, 3 replaces 'm', so the rate of change for this equation is 3.

<h3>Equation C:</h3><h3> $y=0.3x+4$ </h3>

In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.

<h3>Equation D:</h3><h3> $y=0.03x+1$ </h3>

In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.

Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.
