What is 6.79 minus 3.95 rounded to, to the nearest half dollar

likoan [24]

$6.79 - $3.95 = $2.84. Since you’re rounding to the nearest half dollar, you’d found to $3. $2.84 is closer to $3 than $2.50

$3 - $2.84 = $.16
$2.84 - $2.5 = $.34

Juliette [100K]

Answer:

$y = \frac{1}{6}x - 5$

Step-by-step explanation:

The equation that represents the road can be written as $y = mx + b$

Find, m = slope, and b = y-intercept of the line.

Using two points on the line, (-6, -6) and (6, -4), find the slope:

$slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-6)}{6 -(-6)} = \frac{2}{12} = \frac{1}{6}$

Substitute x = -6, y = -6, and m = ⅙ into $y = mx + b$ to find b.

$-6 = \frac{1}{6}(-6) + b$

$-6 = -1 + b$

Add 1 to both sides

$-6 + 1 = b$

$-5 = b$

Substitute m = ⅙, and b = -5 into $y = mx + b$ .

✅The equation that represents the road would be:

$y = \frac{1}{6}x + (-5)$

$y = \frac{1}{6}x - 5$

The function f(x)=70n -400 models the profit of the instructor of a guitar class per month, where n is the number of students en

Ymorist [56]

Answer:

At least 6 students must be enrolled in the class for the instructor to make a profit.

At least 20 students must be enrolled in the class for the instructor to make $1,000 (or more) profit per month.

Step-by-step explanation:

The function $f(x)=70n -400$ models the profit of the instructor of a guitar class per month.

1. If the instructor makes a profit, then

$f(x)>0\\ \\70n-400>0\\ \\7n-40>0\\ \\7n>40\\ \\n>\dfrac{40}{7}\\ \\n>5\dfrac{5}{7}$

So, at least 6 students must be enrolled in the class for the instructor to make a profit.

2. If the instructor needs to make 1,000.00 profit per month, then

$f(x)\ge 1,000\\ \\70n-400\ge 1,000\\ \\7n-40\ge 100\\ \\7n\ge 140\\ \\n\ge \dfrac{140}{7}\\ \\n\ge 20$

So, at least 20 students must be enrolled in the class for the instructor to make $1,000 (or more) profit per month.
