Question

@phi can you check some more work i did

Answer 1

A system of linear inequalities is shown below:

y – x > 0
x + 1 < 0

Which of the following graphs best represents the solution set to this system of linear inequalities?

The first line is a dashed line which joins ordered pairs negative 1, 5 and negative 1, negative 4. The second line is a dashed line and joins ordered pairs negative 2, negative 2 and 4, 4. The portion common to the right of the first line and above the second line is shaded

The first line is a dashed line which joins ordered pairs negative 1, 5 and negative 1, negative 4. The second line is a dashed line and joins ordered pairs negative 2, negative 2 and 2, 2. The portion common to the left of the first line and above the second line is shaded

The first line is a dashed line which joins ordered pairs negative 1, 5 and negative 1, negative 4. The second line is a dashed line and joins ordered pairs negative 2, negative 2 and 2, 2. The portion common to the left of the first line, above the second line and below the x axis is shaded

The first line is a dashed line which joins ordered pairs negative 1, 5 and negative 1, negative 4. The second line is a dashed line and joins ordered pairs negative 2, negative 2 and 3, 3. The portion common to the leftof the first line and above the x axis is shaded

Answer 2

did you get the answer?

Answer 3

yes A

Answer 4

both lines meet at -1 -1

Answer 5

we don't really care where the lines meet (though if this were a system of equations we would care)

but yes, the first option looks good. The only problem is the "first" line and "second" line are swapped when they are listed up top. To match the words, we should list them
x + 1 < 0
y – x > 0

Answer 6

but thats how its lasted.

Answer 7

oh wait. after writing them in the correct order, I see the first equation is
x < -1

that is true for x's to the left of -1
i.e. to the left of the line x= -1

that is choice 2

Answer 8

does it matter what order

Answer 9

It does to me. when they say first equation I look at the first equation (forgetting I should look at the second equation) and get lost.

Answer 10

A system of equations is shown below:

6x – 5y = 5
3x + 5y = 4

The x-coordinate of the solution to this system of equations is _____. for this i think i got it wrong because i put 1 1/5

Answer 11

do you know how to add the 2 equations?

Answer 12

yes thats what i did by eliminating and adding
