Which statement is true about the solution to the set of equations?
There are infinitely many solutions.
There are two solutions.
There is one solution.
There is no solution.

Answers

If you would like to know which statement is true about the solution to the set of equations, you can calculate this using the following steps:

x + y = 2 ... y = 2 - x
2x + y = 4
_________________
2x + (2 - x) = 4
2x - x = 4 - 2
x = 2

y = 2 - x = 2 - 2 = 0

(x, y) = (2, 0)

The correct result would be: There is one solution.

An arc on a circle measures 85°. The measure of the central angle, in radians, is within which range?0 to radians to π radiansπ to radians to π radians

Answers

The measure of the central angle is within 0 to π radians.

Equation

An equation is an expression that shows the relationship between two or more variables and numbers.

Angle in radian = angle in degrees * π / 180

Given that the angle = 85°, hence:

Angle in radian = 85 * (π/180) = 0.472π rad

The measure of the central angle is within 0 to π radians.

What is the fraction ten twelves in its simplest form

Answers

You just divide each by one of there common factors (except from 1 and 0)

Eg.10÷2=5

12÷2=6

This would look like:

10/12

Next look for a common divisor that works for both the top (numerator) and bottom (denominator) numbers. Incidentally, think 'Notre Dame' or ND if you cannot remember which is which.

Dividing by 2 works for both numbers, so dividing the '10' and the '12' by 2 gives you a simplified form of 5/6.

And voila! That's your answer!

Since the creation of a social program, the percent of persons 65 years and over with a family income below the poverty level has declined. The percent can be approximated by the function P(t)=30.71-5.77ln t, where t is the number of years since 1965. Find the percent of persons 65 & over with family income below the poverty level and the rate of change in 1970.

i know how to find the percent, but don't know how to find the rate of change. Please help!
