Answer:
x=-2, y=1
Step-by-step explanation:
To solve a system of equations, you set x+3 and 2x+5 equal to each other and solve. This simplifies to x=-2. Then you plug itin to one of the equations to get y. Hope this helps and have a magnificent day!!!!! Stay safe!!!
A plastic skeleton is
Answer: B. a physical model.
The world has lots of different kinds of models. A mathematical model might be a ball travels according to the equation . This isn't that. A computer model would be a program that somehow simulates a skeleton in the computer, this isn't that either. Our skeleton is an actual physical model just like a model airplane.
Answer:
171 degrees (C)
Step-by-step explanation:
Because you have to find the overall angle you add both angles together, hence giving you 171 (C)
19000 × 12 × 4.25 = 969000
969000 ÷ 100 = 9690
So, 19000 - 9690 = 9310 is the principal.
9690 is the interest.

Answer:
Step-by-step explanation:
Given:
The expression to simplify is given as:
In order to simplify this, we have to use the law of indices.
1.
So,
Substitute this value in the above expression. This gives,
Now, we use another law of indices.
2.
So,
Substitute these values in the above expression. This gives,
Finally, we further simplify it using the law
So,
Therefore, the given expression is simplified as:
