Which function is represented by the graph?

Answers

9514 1404 393

Answer:

f(x) = -2|x| +1

Step-by-step explanation:

The vertical translation is 1 unit upward, and there is no horizontal translation. So, the function will be something of the form ...

f(x) = a|x| +1

The slopes of the lines have a rise/run with a magnitude of 2/1, so the value of 'a' will have a magnitude of 2. The appropriate choice is ...

f(x) = -2|x| +1

Write an equation in point slope form of the line that passes through the point (2,-8) and had a slope of 4

Answers

Point slope: y - y1 = m(x - x1)
Plug those in
Solution: y + 8 = 4(x - 2)

The equation of a line in point-slope form is (y + 8) = 4(x - 2).

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A line passes through the point (x₁, y₁) ⇒ (2,-8) and had a slope of 4.

We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).

∴ The equation of this line is (y + 8) = 4(x - 2).

a man buys a car for 80000 Rs 20,000 more for repairing he sells it for rupees 125000 find its gain

Answers

Answer: 25%

The man buys the car for 80000 units.
For repairing the car, the man spends 20000 units.
The man sells the car for 125000 units.
To find:
The gain percent of the man.
Solution:
The man buys the car for 80000 units.
For repairing the car, the man spends 20000 units.
∴ Total expenditure of the man for the car_
(80000 + 20000) units.
= 100000 units.
The man sells the car for 125000 units.
∴ Gain = (125000 - 100000) units
= 25000 units.
∴ Gain % = (25000×100)/100000
= (25000/1000)
= 25 %.
∴ The gain of the man is 25 %

Answer:

y = 65x + 250

Step-by-step explanation:

Let the linear equation representing the relation between total pay and number of computers sold be,

y = mx + c

Here, m = commission on every computer sold = slope of the linear function

c = weekly salary

y = total pay

x = number of computer sold each week

Since, slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table attached,

Slope of the line passing through (4, 510) and (6, 640),

m = [tex]\frac{640-510}{6-4}[/tex]

= 65

Equation of the line will be,

y = 65x + c

Since, this line passes through (4, 510),

510 = 65(4) + c

c = 510 - 260

c = 250

Therefore, equation of the line will be,

y = 65x + 250

The resulting equation after substitution in system of equations :2y = 6x , x² + y = 28 will be option B : x^2 + 3x = 28

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

The given system of equation are :

2y = 6x.....(1)

[x² + y = 28.........(2)

also, Lisa isolated the variable y in the first equation and then substituted it into the second equation that is :

she substitute y = 3x in second equation :

x^2 + y =28

x^2 + 3x = 28

Therefore, the resulting equation after substitution will be option B : x^2 + 3x = 28

x+2/2x-6=3/8 solve using multiplication property of equality

Answers

The solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

What are expressions?

Expressions are mathematical statements that are represented by variables, coefficients and operators

How to solve using multiplication property of equality?

The equation is given as

x+2/2x-6=3/8

Apply the multiplication property of equality.

So, we have

8(x + 2) = 3(x - 6)

Open the brackets

8x + 16 = 3x - 18

Collect the like terms

5x = -34

Divide both sides by 5

x = -34/5

Hence, the solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]

Answers

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70

1. x = 1.5 rpm

2. x ≈ 0.8182 mi/hr

3. x = 6.6 feet

4. x = 4224 rpm

5. x = 390 rpm

Step-by-step explanation:

The relationship between angular speed and linear speed is given as follows;

Angular speed, ω = Linear speed, v/(Radius, r)

Therefore, we have;

1. When v = 12 cm/min = r = 8 cm , ω = 12/8 = 1.5 rpm

2. When, ω = 4 rpm, and r = 18 feet, v = 4 × 18 = 72 feet/min ≈ 0.8182 mi/hr

3. When, ω = 800 rpm, and v = 60 mi/hr = 1 mi/min, r = x = 1/800 miles = 6.6 feet

4. When v = 60 mi/hr = 63,360 mi/min, r = 15 in , ω = 63360/15 = 4224 rpm

5. When v = 13 in/sec = 780 in/min, r = 2 in, ω = 780/2 = 390 rpm

a. To find the mean, you first have to add all of the numbers together. Keep in note that if there is more than 1 dot above the number, such as 2 or 3 dots, then you must add the the amount of dots there are above it. Next, you want to divide the total amount of the numbers by the total amount of numbers you have added to get this. That will be the mean. The mean represents the average amount of wage the college students earn during a 1-week span.

b. Next, you want to find the median. Put all of the numbers together in a line, ranging from smallest to largest. Whatever number is in the middle is going to be your median. Keep note for this as well that if there is, for example, 2 dots above the number, you will have to write the number two times. The median helps interpret the middle, and separates the lower, and high values.

c. No, a box plot is not the same as a dot plot. It can interpret the median, but not the mean. A box-and-whisker plot is usually used when you want to find the IQR (interquartile range).
