Answer:

the slope, m, is 4 and that the y-intercept, b, is -8

Step-by-step explanation:

Compare the given equation to the slope-intercept form y = mx + b. Here we see that the slope, m, is 4 and that the y-intercept, b, is -8.

melomori [17]

Answer:

300 g

Step-by-step explanation:

36 g = 12% × (daily value)

(36 g)/(12/100) = (daily value) . . . . . . . divide by 12%

(3600 g)/12 = (daily value) = 300 g

<em>Comment on percentages</em>

"Per cent" means "divided by 100". The symbol (%) is a shorthand way to write "/100". So, 12% = 12/100 = 0.12.

<em>Comment on dividing fractions</em>

You can divide fractions by multiplying by the inverse of the denominator:

... a/(b/c) = a × c/b = ac/b

Or, you can express numerator and denominator over the same denominator, then cancel that:

... a/(b/c) = (ac/c) / (b/c) = ac/b

Either way, 36/(12/100) = 3600/12 = 300.

An athlete knows that when she jogs along her neighborhood greenway, she can complete the route in 10 minutes. It takes 20 minu

IgorLugansk [536]

Answer:

10 miles per hour.

Step-by-step explanation:

Let x represent athlete's walking speed.

We have been given that her jogging rate is 5 mph faster than her walking rate, so athlete's jogging speed would be $x+5$ miles per hour.

$\text{Distance}=\text{Rate}\cdot \text{Time}$

10 minutes = 1/6 hour.

20 minutes = 1/3 hour

While walking, we will get $D_{\text{walking}}=x\frac{\text{miles}}{\text{hour}}\cdot \frac{1}{3}\text{hour}$

$D_{\text{walking}}=\frac{x}{3}$

While jogging, we will get $D_{\text{jogging}}=(x+5)\frac{\text{miles}}{\text{hour}}\cdot \frac{1}{6}\text{hour}$

$D_{\text{jogging}}= \frac{(x+5)}{6}$

Since athlete is covering same distance while walking and jogging, so we can equate both expressions as:

$\frac{x}{3}=\frac{x+5}{6}$

Cross multiply:

$6x=3x+15$

$6x-3x=15$

$3x=15$

$\frac{3x}{3}=\frac{15}{3}\\\\x=5$

Therefore, athlete's walking speed is 5 miles per hour.

Jogging speed: $x+5\Rightarrow 5+5=10$

Therefore, athlete's jogging speed is 10 miles per hour.
