Answer:

The graph is attached.
Step-by-step explanation:
Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.
You know that you want to to have at most 25 samples, then:

And you want to have at least 3 times as many sedimentary samples as
metamorphic samples, then:

Therefore, the system of inequalities that model the situation is:

The y-intercept of the line
is:

And the x-intercept is:

Knowing this, you can graph the line
The y-intercept of the line
is:

And the x-intercept is:

Knowing this, you can graph the line.
Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.
Answer:

Step-by-step explanation:
We are given that Point C is in the interior of ∠ABD
We are also given that ∠ABC ≅ ∠CBD
Now ,

Since we are given that ∠ABC ≅ ∠CBD
So,

Answer:
Step-by-step explanation:
Number of attendees the first day = x.
<u>Solve the following equation for x:</u>
- x + (x + 15) = 269
- 2x = 269 - 15
- 2x = 254
- x = 254/2
- x = 127
Use this calculator to find the unit<span> rate. A rate is a </span>ratio<span> comparing 2 quantities of different kinds of </span>units<span>. A </span>unit<span> rate is a rate with 1 in the denominator. If a rate is given and the quantity in the denominator is not 1, </span>unit<span> rate is calculated by finding an equal </span>ratio<span> such that the denominator is 1.</span>
