What is the slope of the equation 5/4x-7/4
Answer:
3rd option ==> 5/4
Step-by-step explanation:
5x/4 means that for every time x increases by 1, y increases by 5/4.
5/4 is the coefficient for x.
Answer:
\(\dfrac{5}{4}\)
Step-by-step explanation:
The general slope-intercept form of a line equation is
\(y = mx + b\)
where m is the slope and b the y-intercept
The given line has the equation:
\(y = \dfrac{5}{4}x - \dfrac{7}{4}\)
Comparing the general equation to this equation tells us that the slope
\(\textr{m } = \dfrac{5}{4}\)
and y-intercept
\(b = -\dfrac{7}{4}\)
2m+1 _2m÷2m:simplify
Simplify the expression.

What is the slope of the line that passes through the points (-6, 8)(−6,8) and (-16, 33) ?(−16,33)? Write your answer in simplest form.
Given:
A line passes through the points (-6, 8) and (-16, 33).
To find:
The slope of the line.
Solution:
If a line passes through two points, then the slope of the line is
\(m=\dfrac{y_2-y_1}{x_2-x_1}\)
The line passes through the points (-6, 8) and (-16, 33). Using the above formula, the slope of the line is
\(m=\dfrac{33-8}{-16-(-6)}\)
\(m=\dfrac{25}{-16+6}\)
\(m=\dfrac{25}{-10}\)
\(m=-2.5\)
Therefore, the slope of the line is -2.5.
Slope of the line passing through the points ( -6,8) and (-16,33) will be -2.5.
Given information:
The line passes through the points ( -6,8) and (-16,33).
It is required to find the slope of the line.
Slope of the line passing from two points \((x_1,y_1) \; and\; (x_2, y_2)\) can be written as
\(m= \dfrac{y_2-y_1}{x_2- x_1}\)
So, the slope of the given line can be calculated as,
\(m= \dfrac{33-8}{-16- (-6)}\\m = \dfrac{25 }{-10} \\m = -2.5\)
Therefore the slope of given line will be -2.5.

Triangle DEF has vertices D(0,0), E(7,0), and F(3,7).
The altitudes of triangle DEF intersect at point
Answer:
(3, 1.7)
Step-by-step explanation:
The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.
Two lines are perpendicular if the product of their slopes is -1.
The slope of the line joining D(0,0), F(3,7) is:
\(m_1=\frac{7-0}{3-0}=\frac{7}{3}\)
The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:
\(y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)\)
The slope of the line joining E(7,0), and F(3,7). is:
\(m_1=\frac{7-0}{3-7}=-\frac{7}{4}\)
The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:
\(y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)\)
The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:
x = 3, y = 1.7

The only unit variable costs for sumer for the 8 -ounce can will be $0.50. The only $0 for labor. The company inthe product are $0.18 for materials and $0.06 percent off the suggested retail price tends to give retailers a margin of 20 percent of the retailers' cost of the item. a. At what price will Diversified Citrus Industries be selling its prod. uct to wholesalers? b. What is the contribution per unit for Zap? c. What is the break-even unit volume in the first year? d. What is the first-year break-even share of market?
Diversified Citrus Industries will sell Zap to wholesalers at a price of $0.035 per 8-ounce can. The contribution per unit for Zap is -$0.205, indicating potential profitability issues.
a. To determine the price at which Diversified Citrus Industries will be selling its product to wholesalers, we need to consider the suggested retail price, the unit variable costs, and the desired margins for retailers and wholesalers. The suggested retail price to the consumer for the 8-ounce can is $0.05. The unit variable costs for the product are $0.18 for materials and $0.06 for labor. The company intends to give retailers a margin of 20% off the suggested retail price and wholesalers a margin of 10% of the retailer's cost.
Price to Wholesalers = Suggested Retail Price - Retailer's Margin - Wholesaler's Margin
Price to Wholesalers = $0.05 - ($0.05 * 20%) - ($0.05 * 10%)
Price to Wholesalers = $0.05 - $0.01 - $0.005
Price to Wholesalers = $0.035
Therefore, Diversified Citrus Industries will be selling its product to wholesalers at a price of $0.035 per 8-ounce can.
The contribution per unit for Zap can be calculated by subtracting the unit variable costs from the selling price to wholesalers:
Contribution per Unit = Price to Wholesalers - Unit Variable Costs
Contribution per Unit = $0.035 - ($0.18 + $0.06)
Contribution per Unit = $0.035 - $0.24
Contribution per Unit = -$0.205
Since the contribution per unit is negative, it means that the variable costs exceed the price to wholesalers. This suggests that the product may not be profitable in its current pricing and cost structure.
The break-even unit volume in the first year can be calculated by dividing the fixed overhead costs by the contribution per unit:
Break-even Unit Volume = Fixed Overhead Costs / Contribution per Unit
Break-even Unit Volume = $90,000 / (-$0.205)
However, since the contribution per unit is negative, the break-even unit volume cannot be determined using this approach.
The first-year break-even share of the market cannot be determined based on the information provided. The total market size and the expected sales volume of Zap are not specified, making it impossible to calculate the market share at the break-even point.

At 2 Hornets games on a weekend, the team gave out a free basketball to every 90th person who attended the games. • On Saturday, 16,472 people attended the game. • On Sunday, 12,624 people attended the game. How many people received a basketball?
The total number of people received basketball is 323 at 2 Hornets games on a weekend, the team gave out a free basketball to every 90th person who attended the games.
To work out the quantity of individuals who got a ball at the Hornets games, we want to initially find the quantity of participants who might meet all requirements for a b-ball. This is finished by separating the complete number of participants by 90, since the group gives out a b-ball to each 90th individual. For Saturday's down, 16,472/90 = 183.022, and that implies that 183 individuals got a b-ball. For Sunday's down, 12,624/90 = 140.267, and that implies that 140 individuals got a ball. Hence, a sum of 183+140 = 323 individuals got a ball at the two Hornets games throughout the end of the week.

suppose f : z → z is defined as f = © (x,4x 5) : x ∈ z ª . state the domain, codomain and range of f . find f (10).
The answer is f(10) = (10, 45).
The function f: Z → Z is defined as f = {(x, 4x+5) : x ∈ Z}, where Z is the set of integers. The domain of f is Z, which is the set of all integers. The codomain of f is also Z, which means that the function maps integers to integers.
The range of f is the set of all possible values that f can take. To find the range of f, we can plug in a few values of x and see what values of f we get. For example, when x=0, f(0) = (0,5), when x=1, f(1) = (1,9), when x=-1, f(-1) = (-1,1), and so on. It appears that the range of f is the set of all ordered pairs of the form (x, y) where y is an odd integer. Thus, the range of f is {(x,y) : x ∈ Z, y ∈ 2Z+1}.
To find f(10), we plug in x=10 into the definition of f: f(10) = (10, 4(10)+5) = (10, 45). Therefore, f(10) = (10, 45).

Suppose the mean height in inches of all 9th grade students at one high school estimated. The population standard deviation is 3 inches. The heights of 8 randomly selected students are 66,65, 74, 66, 63, 69,63 and 68.
The mean, Margin of error at 99% confidence level and 99% confidence interval for the given data is 66.75 inches, 2.73 inches and [64.02, 69.48] respectively.
Mean is the arithmetic average of all the observations.
Mean = Sum of all the observation/ Total no.ofobservation
= 66 + 65 + 74 + 66 + 63 + 69 + 63 + 68 / 8
= 534 / 8 = 66.75 inches
Standard error = Standard deviation / √n
= 3 /√8 = 1.06 inches
Margin of error = Z * Standard error
Where Z, is the critical value (corresponding to the desired confidence level)
Using standard normal distribution we get Zvalue roughly around 2.576.
= 2.576 * 1.06 = 2.73 inches
Confidence Interval = ( Mean - Margin of error), (Mean + Margin of error)
= 66.75 - 2.73, 66.75 + 2.73
= [64.02, 69.48]
Therefore, the mean height is 66.75 inches, the margin of error at 99% confidence level is 2.73 inches, and the 99% confidence interval is [64.02, 69.48].
