2 answers:

3 0

Reduce the expression, if possible, by cancelling the common factors.

Exact Form:
−4/15

Decimal Form:
−0.26

Basically do
y2-y1 divided by x2-x1
14-10 divided by -7-8
which equals -4/15

Which system of linear inequalities is graphed?

ANEK [815]

To determine the system of inequality that has been graphed, we need to be very smart.

Observe that all the equations are the same.

Also note that all the lines are solid. This should tell you that the inequities should involve.

$\ge \:or\: \le$

Therefore the answer is between option A and B.

So we choose a point in the solution region to discriminate between A and B.

Let us choose the origin since that is easy to evaluate.

We substitute into option A to get.

$y\le 3x-1\:and\: x+ 3y \ge 6$

$0\le 3(0)-1\:and\: 0+ 3(0) \ge 6$

$0\le -1\:and\: 0\ge 6$

The above statements are false

We now substitute into option B

$y\ge 3x-1\:and\: x+ 3y \le 6$

$0\ge 3(0)-1\:and\: 0+ 3(0) \le 6$

$0\ge-1\:and\: 0 \le 6$

Both statements are true, therefore the correct answer is option B.

*PLEASE HELP ME* (math attachment) IT'S PAST MIDNIGHT I'M TIRED AND DESPERATE

Luda [366]

<h3><u>Answer:</u></h3>

<h3><u>Step-by-step explanation:</u></h3>

let's rewrite this

x + y = 11 <em>- equation 1</em>

- x = - y - 9 <em>- equation 2</em>

solve the first equation for x

x + y = 11 (add -y to both sides to get x by itself)

x = -y + 11 <em> - equation 3</em>

now substitute -y + 11 for x in the second equation

y - 11 = - y - 9 (2 negative signs next to each other equals positive)

2y - 11 = -9 (add y to both sides)

2y = 2 (add 11 to both sides)

y = 1 (divide both sides by 2)

now substitute y = 1 into equation 3

x = -1 + 11

x = 10

therefore, x = 10 and y = 1. in coordinates, x goes before y

therefore, the coordinates are (10, 1)

therefore the answer is D

good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9
