Answer:

The slope is -2.

Step-by-step explanation:

The slope formula is (y1-y2)/(x1-x2)

or change in y / change in x.

First, you plug in your numbers. I will use (2, 7) as (x1, y1)

(1-7)/(5-2)

Next, simplify.

(-6)/(3)

-2

And that's your slope!

Madelyn hikes 190.5 meters up a mountain. If she is 62% of the way up, how tall is the mountain?

ira [324]

Answer:

307 Meters

Step-by-step explanation:

$\frac{62}{100} = 190.5\\
Cross multiply:

62w = 100(190.5)

Multiply 100 by 190.5:

62w = 19,050

Solve for w:

Divide both sides by 19,050 to isolate the variable and get the answer

19,050/62 = 307.25.....

~ After rounding to the nearest percent, the answer is 307$

suppose y varies directly with x, an dy = 10 when x =3. what direct variation equations relates x and y?

Ratling [72]

The direct variation equation relates x and y is y = $\frac{10}{3}$ x

Step-by-step explanation:

Direct variation is when one variable is equal to a constant times another variable

If y varies directly with x, then

y ∝ x
y = k x is the equation of variation
k is the constant of variation

∵ y varies directly with x

∵ y ∝ x

∴ y = k x

∵ y = 10 when x = 3

- Substitute these values in the equation above to find k

∴ 10 = k(3)

∴ 10 = 3 k

- Divide both sides by 3

∴ k = $\frac{10}{3}$

∴ The equation of variation is y = $\frac{10}{3}$ x

The direct variation equation relates x and y is y = $\frac{10}{3}$ x

Joe dealt 20 cards from a standard 52-card deck, and the number of red cards exceeded the number of black cards by 8. he reshuff

galben [10]

First deal there are 14 red and 6 black so fraction of red = 14/20 or 0.7
second deal there are 20 red and 10 black so fraction of red = 20/30 or 0.67

0.67 is closer to 1/2 that 0.7 so

c is the correct choice
