Which system of linear equations appears to have a solution of (3, 0)? On a coordinate plane, 2 lines intersect at (0, negative 2). On a coordinate plane, 2 lines intersect at (0, 1). On a coordinate plane, 2 lines intersect at (3, 0). On a coordinate plane, 2 lines intersect at (0, 3).

Given:

Solution of system of equation is (3,0).

To find:

The system of linear equations appears to have a solution of (3, 0).

Solution:

If a system of linear equation has two equations and graph of these two equation intersect each other at (a,b), then the point (a,b) is the solution of that system of equations.

Since, the solution of system of equation is (3,0), therefore on a coordinate plane, 2 lines intersect at (3, 0).

Hence, the correct option is C.

We have that the sum of two numbers  is 9

this can be written as:

x + y  = 9

where x is the larger number.

Now we want to write:

"the difference between one more than the larger number and twice the smaller number"

First, remember that the difference between A and B is:

A - B

Then "the difference between one more than the larger number and twice the smaller number"

is:

"one more than the larger number" = ( x + 1)

"twice the smaller number" = 2*y

the difference between these is:

(x + 1) - 2*y

Now we can simplify:

We know that:

x + y = 9

then:

y = 9 - x

replacing that in the equation:

(x + 1) - 2*y

we would get:

x + 1 - 2*(9 - x)

x + 1  -18 + 2x

(x + 2x) + (1 - 18)

3x - 17

This means that we can write:

"the difference between one more than the larger number and twice the smaller number"

as: 3x - 17
