What does x equal? 5(x − 1) = 5x -1

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)

m = 32 / 8

m = 4

A 2units

B 4 units

C 10 units or

D 14 units

Find out the distance between the given vertices

we have that

the two coordinates have the same x-coordinate

that means

the distance between the points is the difference of the y-coordinates

8-(-6)=8+6=14 units

Problem N 2

we have that

between -1 and -2 there are 5 spaces

the value of each space is 1/5=0.20

therefore

point A is -1.60

option C

Given the following question:

The family spends 90 dollars at a grocery store each week

The family spends 40 dollars each time they go out to eat.

Part one:

If the family goes out to eat four times they would have spent 250 dollars.

Part two:

The final point on the graph is (6, 330)

Which means if the family goes out six times, the budget is 330 dollars.

So, your answer is 6.

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

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

A rational number is a number that can be expressed as a ratio of two integers. Integers can be positive or negative. Rational numbers are simply fractions. For example;

-5/2, -1/5, 3/1, 4/5 etc are all rational numbers because we can write them as a ratio of two integers.

Since some of this fractions can lead to both negativa and positive integers, hence rational number is a positive or negative whole number including 0.

Hence all the options are correct since rational numbers are are also repeating decimals

Step-by-step explanation:

Given equations:

To solve the given equations by substitution, substitute the first equation into the second equation and solve for x:

[tex]\begin{aligned}\textsf{Equation 2}: \quad 2y+5x&=13\\\\y=10x+4 \implies 2(10x+4)+5x&=13\\20x+8+5x&=13\\25x+8&=13\\25x+8-8&=13-8\\25x&=5\\\dfrac{25x}{25}&=\dfrac{5}{25}\\x&=\dfrac{1}{5}\end{aligned}[/tex]

Substitute the found value of x into the first equation and solve for y:

[tex]\begin{aligned}\textsf{Equation 1}: \quad y &=10x+4\\\\x=\dfrac{1}{5} \implies y&=10\left(\dfrac{1}{5}\right)+4\\y&=\dfrac{10}{5}+4\\y&=2+4\\y&=6\end{aligned}[/tex]

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.
