Each inch in the map is equivalent to 8 miles.
Explanation:
There is a distance of 24 miles between two parks. This 24 miles is represented by an 8-inch gap in the map.
So 8 inches on that particular map = 24 miles in real life.
To find the distance that an inch on the map represents we must divide both sides of the above equation. Since we need to calculate how much distance 1 inch represents we divide both the sides by 8 so that 8 inches on the map changes into 1 inch.
inches on the map = miles between the two parks in real life,
1 inch on that particular map = 3 miles in real life.
So each inch on the given map is equal to 8 miles in real life.
Answer:
The equation is c=2n
The constant of proportionality is 2
$18 will buy 9 cups of coffee
Step-by-step explanation:
Cost c=2*n
where c is the number of cups
The constant of proportion is 2
If cost is $18, then
18 = 2n
n = 18/2
n = 9
$18 will purchase 9 cups of coffee
Mean: Add up all the numbers and divide that by 10
Median: Middle number
Vertical asymptotes ares found where the function is undefined. f(x) is undefined when the denominator equals zero:
x^2-1=0
<em>*Add 1 to both sides*</em>
x^2=1
<em>*Take the square root of both sides*</em>
x=+/-1
There are vertical asymptotes at x=-1 and x=1.
Hope this helps!!
The
<u>correct answer</u> is:
The relationship is linear, and the equation is
y-5 = 2(x+7).
Explanation:
To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:
The slope between the <u>first two points</u> is given by:
The slope between the <u>second pair of points</u> is given by:
The slope between the <u>third pair of points</u> is given by:
Since the <u>slope is the same</u> throughout the data, the <u>relationship is linear</u> and the slope is 2.
To write the equation, we use point-slope form, which is:
y-y₁ = m(x-x₁)
Using the first point, we have:
y-5 = 2(x--7)
y-5 = 2(x+7)
