Answer:

-2

Step-by-step explanation:

slope form: y2-y1/x2-x1

points: x1, y1 (2,7)  and x2,y2 (-4,19)

substitute the points into the form: 19-7/-4-2

simplify: 12/-6 = -2

For the given values of x and y, the value of y/x (that represents the slope of the equation) = 3/1, 3/1, 3

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.

Given are the values of the x and y

y/x represents the slope of the equation,

for x = -1 and y = -3,

y/x = 3/1

for x = 1 and y = 3

y/x = 3/1

for x = 2 and y = 6

y/x = 6/2 = 3

Benji's total score is -2.

If two numbers are negative, their sum will also be negative. When two negative numbers are added together, their value is further diminished, hence the sum of the two negative numbers is always negative.

Given:

Benji has four -0.5 cards.

According to the question, we have to determine his total score which will be equal to adding scores on all four cards.

As we are adding negative scores, upon adding them place a negative sign in front of the sum.

The total score of Benji = (-0.5) + (-0.5) + (-0.5) + (-0.5)

                                        = -2

Therefore, his total score is -2.

The correct statement regarding the function on the table is given by:

D. The maximum number of tablet sales the store made occurred 7 years after 2010

The meaning of the function is that it gives the number of tablets sold, in thousands, in y years after 2010, hence the variables are given by:

For example, T(-1) = 0 = 17 means that 17,000 were sold in the year of 2009.

There was a single decrease, from 2017 to 2018, that is, year 7 to year 8, hence statement B is false.

For item C, we have no information whether this number is true, hence the statement is false, as the function gives the number of tablets sold at the store, not the number of people using the tablets.

The true statement is given by option D, since f(7) = 130 is the maximum value of the function.

Step-by-step explanation:

The time that the tank began leaking water is 12:40am

The time the tank will be empty is  11 : 23 pm.

The function that would determine the amount of water in the tank is a linear function. A linear function is a function that has a single power that is raised to the power of one. When drawn on a graph, a linear function is a straight line.

The first step is to determine the rate of leakage of the tank.

Rate = (water in the tank at 11am - water in the tank at 8:30am) / change in time

(137 - 115) / (11 - 8:30)

22 / 2:30

22 ÷ 2 1/2 hours = 8.8 gallons per hour

Linear function would have this form:

Water in the tank = water in the tank when full - (rate of leakage x number of hours)

137 = 200 - (8.8xh)

137 = 200 - 8.8h

200 - 137 = 8.8h

63 = 8.8h

h = 63 / 8.8

h = 7.16 hours = 7 4/15 hours

8 -  7 4/15 hours = 12 10/15 hours = 12.40am

When the tank is empty:

0 = 200 - 8.8h

200 - 0 = 8.8h

200 / 8.8 = 22.72 = 22 hours 43 minutes

22 hours 43 minutes + 12 : 40M = 11 : 23 pm

The simplification of the number (9-2/square root of 9)⁻² +(1-6)² is found as 25.18.

Simplify simply signifies to make something easier to understand. Simply or simplification in mathematics refers to reducing an expression /fraction /problem to a simpler form. It simplifies the problem by calculating and solving it.

We can —

For the given question;

The expression is given as;

(9-2/square root of 9)⁻² +(1-6)²

This can be written as;

= [(9-2)/√9]⁻² + (1-6)²

Do the prime factorization of √9 = √3×3

= [(9-2)/√3×3]⁻² + (1-6)²

On solving;

= [7/3]⁻² + (-5)²

Taking the reciprocal of first term

= (3/7)² + (-5)²

= (0.42)² + (-5)²

Squaring the values;

= 0.18 + 25

= 25.18

Given,

A design engineer is mapping out a new neighborhood with parallel streets. If one street passes through (4, 5) and (3, 2)

To find the equation for a passes through (2, -3).

How to determine an equation of the line parallel to another line

In this question we must derive the equation of the line for a given street and look for another equation of the line parallel to the previous one. Lines are first order polynomials of the form y = m · x + b, where m and b are the slope and the y-intercept, respectively.

Now, According to the question:

Now we present the procedure in detail. First, find the equation of the first line:

5 = 4 · m₁ + b₁           (1)

2 = 3 · m₁ + b₁          (2)

(m₁, b₁) = (3, - 7)

Second, determine the equation of the line parallel to the line found in the previous step: (Please notice that two lines are parallel to each other when they share the same slope but have different y-intercepts)

-3 = 3 · 2 + b₂

b₂ = -3 - 6

b₂ = - 9

We can hold 3 and flip the fraction, 1/4. If we flip 1/4, it becomes 4/1 and the division sign becomes multiplication. The expression would be

3 x 4/1 = 12

The correct option is A

By using the secant line formula, the average rate of change of function f(x) on the interval [3, 11] is equal to 4.

In accordance with the statement, we must determine the average rate of change for a given closed interval of the function f(x). Graphically speaking, the average rate of change for this interval is represented by the slope of the secant line passing through the two limits of the interval [a, b], which is found by secant line formula:

m = [f(b) - f(a)] / (b - a)

If we know that a = 3, f(a) = 19, b = 11 and f(b) = 51, then the average rate of change is:

m = (51 - 19) / (11 - 3)
