Answer:
x = 2, y = 3
Step-by-step explanation:
5x – 4y = -2
2x + 4y = 16
<em></em>
<em>Solve by elimination. (-4y and +4y gives 0)</em>
7x = 14
x = 2
<em>Substitute 2 in one of the equations in order to find y.</em>
5(2) - 4y = -2
10 - 4y = -2
-4y = -12
y = 3
x = 2, y = 3
hope this helps!! p.s. i really need brainliest :)

Answer:
Step-by-step explanation:
<u>If I got it right, we have:</u>
- Formula Pf = P0*e^(rt)
- Pf = 75709
- P0 = 1349
- r = 25% = 0.25
- t = ?
<u>Substitute the given values and solve for t:</u>
- 75709 = 1349*e^(0.25t)
- e^(0.25t) = 75709/1349
- e^(0.25t) = 56.1223
- ln e^(0.25t) = ln 56.1223
- 0.25t = 4.03
- t = 4.03/0.25
- t = 16.12 hr
The order of magnitude is the same thing as saying the scientific notation which is 4x10 to the power of six. The important thing about scientific notation is that there has to be a number only in the tens place but nothing in the hundreds and thousands.

Answer:
see attached
Step-by-step explanation:
a) A system of equations has no solutions when the graphs of those equations do not intersect. If the equations are equations of a line, then the lines must be parallel in order for them not to intersect.
Any parallel line will do.
__
b) There is one solution when the graphs intersect in exactly one point.
Any line that crosses the one shown will do.
__
c) There are infinite solutions when the graphs describe the same curve.
A line overlapping the one shown is the one you want.
