The graph of y = -3x+5

Step 1: Since the y - intercept is 5, plot the point (0,5).

Step 2: Since the slope is -3, move 1 unit to the right and 3 units down, so plot the point (1,2).

Step 3: Connect those points by a straight line.

WINSTONCH [101]

Answer:

Yes.

Step-by-step explanation:

Just like normal algebra, you factor our the common factor, in this case, 5.

Thus,

$\sin(5(x + 4))$

alexira [117]

Answer:

13.2

Step-by-step explanation:

√175 ≈ 13.2 . . . units

The area of a square is the square of the edge length. Hence, the edge length is the square root of the area.

An area of 18 square feet that is 6 feet long and 3 feet wide. A rug covered 1/3 square foot tiles. How many tiles will the rug

Shkiper50 [21]

Answer:

The number of tiles the rug will cover is 54 tiles

Step-by-step explanation:

Here we have,

Total area covered by the rug = 18 ft²

Size of one tile = 1/3 ft²

Therefore the number of tiles that can fit into the the area is given by;

Total area of the rug ÷ Area of one tile

= 18 ft² ÷ 1/3 ft²

Here we note that we are dividing a number by a fraction which is the same as multiplying the number by the inverse of the fraction as follows

= 18 × 3/1 ft²/ft² = 54 tiles

The number of tiles the rug will cover = 54 tiles.

Fran swims at a speed of 2.8 mph in still water. The Lazy River flows at a speed of 0.6 mph. How long will it take Fran to swim

kati45 [8]

Answer:

1. Upstream Time: 1 hour (or 60 minutes)

2. Downstream Time: 0.65 hour (or 39 minutes)

Step-by-step explanation:

The time it will take goes by the distance formula:

$D=RT$ , where D is the distance, R is the rate (speed), and T is the time.

For Upstream, you are going <em>against</em> the current, so your still water speed slows down. So upstream rate is still water rate - stream rate. So 2.8 - 0.6 = 2.2mph

Time it will take him to swim 2.2 miles, is:

$D=RT\\2.2=2.2(T)\\T=\frac{2.2}{2.2}=1$

So, 1 hour

For Downstream, you are going <em>with</em> the current, so your still water speed increases. So downstream rate is still water rate + stream rate. So 2.8 + 0.6 = 3.4 mph

Time it will take him to swim 2.2 miles, is:

$D=RT\\2.2=3.4(T)\\T=\frac{2.2}{3.4}=0.65$

So, 0.65 hours (or 0.65*60=39 minutes)
