The answer is y_>-2/3-4

The intercept form is y = mx + b and in terms of inequalities it would be
y (<, >, ≤, ≥)

You need to bring 6x to the other side of the inequality to make it into the intercept form...
6x - 4y < 20
6x - 6x - 4y < 20 - 6x
-4y < 20 - 6x
Divide both sides by -4 to isolate y. Since you are dividing by a negative coefficient you need to switch the direction that the inequality to pointing to.
y > -5 + 6/4
or more simplified ..
y > -5 + 2/3

-18 = -6n - 6 + 2n Solve for n.

vodomira [7]

Answer:

n = 3

Step-by-step explanation:

-18 = -6n - 6 + 2n

-18 = -6n +2n -6 (Combine like terms)

-18= -4n -6

-18+6= -4n -6+6 (Addition Property of Equality)

-12 = -4n

-12/-4 = -4n/-4 (Division Property of Equality)

3=n

The value of 'n' is 3.

Please hurry , help please??? find the values of the variables

MArishka [77]

Answer:

x=60

Step-by-step explanation:

The angles here are alternate interior angles, this means that they are congruent. Congruent means that they are equal to each other, so to solve just set them equal! (Your variable is x so you're solving for that)

$2x=120\\x=60$

Hope this helps! :)

Which are solutions of the equation 4x2 – 7x = 3x + 24? Check all that apply.

SCORPION-xisa [38]

Answer:

{-3/2, 4}

Step-by-step explanation:

Use synthetic division here. If the remainder is 0, then the divisor is a root or solution.

Here we have x = -4. Perform the synthetic division as follows:

-4 4 -10 -24

-16 108

------------------------------

4 -26 84 The remainder is 84, which tells us -4 is NOT

a root/solution.

Try -3/2 as divisor this time:

-3/2 4 -10 -24

-6 24

------------------------------

4 -16 0 Remainder is 0, so -3/2 is a solution

Show in the same manner that 4 is a solution also. Or determine whether x - 4 satisfies 4x - 16 = 0 (it does).

Ravi has $445 in his savings account. He wants to save at least $795. Write and solve an inequality to determine how much more m

Alexxandr [17]

Given

Ravi has $445 in his savings account.

He wants to save at least $795.

Write and solve an inequality to determine how much more money Ravi must save to reach his goal.

To proof

As given

amount of money in dollars Ravi must save to reach his goal be = d

Ravi has in his savings account = $445

He wants to save at least $795

than the inequality become in the form

$445 + d \leq 795\\ 795 - 445 \leq d\\ 350\leq d$

thus $350 Ravi must save to reach his goal.

Hence proved
