How many solutions does the system have?

Mathematics
1 answer:
kykrilka [37]2 years ago
6 0

Answer: a

Infinitely many

Step-by-step explanation:

Solve by substitution:

1) Solve y=2x+1 for y:

y=2x+1

2) Substitute 2x+1 for y in -4x+2y=2:

-4x+2y=2

-4x+2(2x-1)=2

3) Simplify both sides of the equation:

2=2

4) Add -2 to both sides of the equation:

2+-2=2+-2

5) Simplify both sides of the equation:

0=0

Therefore, there are infinitely many solutions.

Solve by elimination:

You cannot solve this system by elimination

Solve by graphing:

The 2 equations are on top of each other, therefore, the system of equations has infinitely many solutions.

Likurg_2 [28]

Years for one serious accident is 10 year

<u>Given:</u>

Probability of having a serious accident = 10% every year

P(serious accident) = 0.1

Number of years = n

<u>Computation:</u>

Years for one serious accident = 1 / Probability of having a serious accident

Years for one serious accident = 1 / P(serious accident)

Years for one serious accident = 1 / 0.1

Years for one serious accident = 10 year

Where does f(x) = g(x)
olya-2409 [2.1K]

f(x) = g(x) at x = 2.

In order to find this, you look for where the two graphs intersect. In this case, they intersect at the point (2, 5). At this point, both f(x) and g(x) both equal 5. So to identify the point, we need to look at the x value of the ordered pair, which is x = 2.
