Answer:

c) y=\frac{2}{3} x+9

Step-by-step explanation:

The way I solve these is...

First, you look at where the line crosses the y-axis because that's your b in the y=mx+b equation. Which is 9

Then I find a point where the line passes thru so for example, (-6,5) Remember that x point is always before the y.

From there I determine if the line is positive or negative, this one's positive because the line goes up from left to right, if it were going up from right to left, then it'd be negative.

So knowing it's positive we count the points up and to the right until reaching the next point. So first go up 2 points and then right 3.

Knowing this, remember that it's always rise over run for the slope, so we rose 2, and ran 3. so, the slope is 2/3

This gives us our equation of y=\frac{2}{3} x+9

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 ta
Simora [160]

Answer:

\frac{21}{4} 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 = \frac{3}{4} quarts

Multiplying by 7 on both sides:

Amount of water leaked in 7 days = \frac{3}{4}\times 7 = \frac{21}{4} 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 \times 3 = 9 quarts = 4 \times 3 = <em>12 days</em>

Find the area of each figure. Round to the nearest tenth if necessary.
Nataly_w [17]

Answer:

220ft^2

Step-by-step explanation:

In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft

In blue: 18ft - 12ft = 6ft

The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3

total rectangle area: 12ft x 18ft = 216

216 - (3 + 3) = 216 - 6 = 200            subtract 6, we added that area in

SOVA2 [1]

Answer:

x=158

Step-by-step explanation:

109=-x+267

-267     -267

-158=-x

x=158

(also i noticed part of your question says x=(?)*5 and 31.6*5 is 158 so that would be 31.6)
