Answer 1

Answer:

when x = -1,  y = -3

when x = -1,  y = -1

when x = -1,  y = 1

when x = -1,  y = 3

Step-by-step explanation:

x = -1;  plug in y = 2(-1) - 1 = -2 - 1 = -3

x = 0;  plug in y = 2(0) - 1 = 0 - 1 = -1

x = 1;  plug in y = 2(1) - 1 = 2 - 1 = 1

x = 2;  plug in y = 2(2) - 1 = 4 - 1 = 3

What are the x- and y-intercepts of the line? 2x – 3y = –12
Show work

Answers

Answer:

You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

Step-by-step explanation:

Answer:

x = -6  y = 4

(-6,0)  (0,4)

Step-by-step explanation:

2x - 3y = -12

cancel out the y

2x - 3(0) = -12

2x = -12

divide both sides by 2

x = -6

2x - 3y = -12

cancel out the x

2(0) - 3y = -12

-3y = -12

divide both sides by -3

y = 4

An aquarium is leaking water at the rate of three quarts in 4 days.How many quarts are leaked in 1 week?How many days does it take for 9 quarts to leak out of the aquarium?

Answers

Answer:

[tex]\frac{21}{4}[/tex] quarts

12 days

Step-by-step explanation:

Given that:

Amount of water leaked in 4 days = 3 quarts

To find:

Number of quarts leaked in 1 week?

Number of days taken for the leakage of 9 quarts of water?

Solution:

We can simply use unitary method or the ratio to find the answers of the questions asked in the statement.

As per question statement:

Amount of water leaked in 4 days = 3 quarts

Dividing by 4 on both sides:

Amount of water leaked in 1 day = [tex]\frac{3}{4}[/tex] quarts

Multiplying by 7 on both sides:

Amount of water leaked in 7 days = [tex]\frac{3}{4}\times 7 = \frac{21}{4}[/tex] quarts

Number of days taken for the leakage of 3 quarts = 4 days

Multiplying by 3 on both sides:

Number of days taken for the leakage of 3 [tex]\times[/tex] 3 = 9 quarts = 4 [tex]\times[/tex] 3 = 12 days

12x─ 15 = 6 ─ 3x answered as a fraction

Answers

Answer:

x=1.4 or 21/15

Step-by-step explanation:

Answer:

x is equal to one and two fifths.

Step-by-step explanation:

Given:

12x - 15 = 6 - 3x

Let's start by noticing that every term in that equation is divisible by 3.  That means we can factor 3 out of it, giving us:

4x - 5 = 2 - x

Now we'll add x to both sides:

4x + x - 5 = 2 - x + x

5x - 5 = 2

An then we add 5 to both sides:

5x - 5 + 5 = 2 + 5

5x = 7

Finally, we can divide both sides by 5 to get the final answer:

5x ÷ 5 = 7 ÷ 5

x = 7/5

To put that in proper form it would be:

[tex]x = 1 \frac{2}{5}[/tex]

Find the value of x in the figure.

(4x-3)

118
(3x+6)

Answers

Answer:

x = 35

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6, then

sum = 180° × 4 = 720°

sum the given angles and equate to 720

4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x - 3 = 720, that is

14x + 230 = 720 ( subtract 230 from both sides )

14x = 490 ( divide both sides by 14 )

x = 35
