Please help asap

Answers

Answer 1

Answer:

f(4) for the function [tex]f(x) = 7x + 6[/tex] is [tex]\mathbf{f(4)=34}[/tex]

Step-by-step explanation:

We need to find f(4) for the function [tex]f(x) = 7x + 6[/tex]

For finding f(4) we will put x= 4 in the given function

[tex]f(x) = 7x + 6[/tex]

Put x = 4

[tex]f(4)=7(4)+6\\f(4)=28+6\\f(4)=34[/tex]

SO, f(4) for the function [tex]f(x) = 7x + 6[/tex] is [tex]\mathbf{f(4)=34}[/tex]

The length of a right triangle's hypotenuse with a theorem created long ago is c² = a² + b², where 'c' = the hypotenuse of the right triangle and 'a' and 'b' are the other two legs.

We need to find the length of a right triangle's hypotenuse with a theorem created long ago.

What is a Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

The Pythagoras theorem equation is expressed as, c² = a² + b², where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs. Hence, any triangle with one angle equal to 90 degrees produces a Pythagoras triangle and the Pythagoras equation can be applied in the triangle.

Therefore, the length of a right triangle's hypotenuse with a theorem created long ago is c² = a² + b², where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs.

The table that represents the linear function is table (B)

How to determine the linear function?

As a general rule, a linear function is any function that has a constant rate of change

This means that as the function independent value changes by a constant, the function dependent value changes by a constant

In other words, as the function x value changes by a constant, the function y value changes by a constant

Using the above as a guide, we can see the table B represents a linear function

This is so because, as x increases by 3, the y value decrease by -2

Hence, the table that represents the linear function is table (B)

write an equation of the line . through (1,-2);parallel to 2x=3y+4

Answers

Answer:

y = 2/3x - 8/3

or 2x = 3y + 8

Step-by-step explanation:

2x = 3y + 4

3y = 2x - 4

y = 2/3x - 4/3

If two lines are parallel, their slopes are equal

if m = 2/3, y = -2, x = 1

y = mx + b

-2 = 2/3(1) + b

-2 = 2/3 + b

b = -2 - 2/3 = -8/3

y = 2/3x - 8/3

Answers

Answers:

A ' = (-3, -3)

B ' = (1, 0)

=====================================================

Explanation:

To translate 6 units to the left, we subtract 6 from each x coordinate.

For point A, we have x = 3 become 3-6 = -3 as the new x coordinate.

Point A also goes down 7 units, in which we subtract 7 from the y coordinate. So the y coordinate of point A, which is 4, becomes 4-7 = -3 as the new y coordinate.

This is how we can write out the work shown for moving point A

[tex](\text{x},\text{y})\to(\text{x}-6,\text{y}-7)\\\\(3,4)\to(3-6,4-7)\\\\(3,4)\to(-3,-3)[/tex]

Point A is at (3,4) and moves to A ' which is at (-3, -3)

The equations that match the diagram are 18 ÷ 3 = x + 5 and 3(x + 5) = 18

How to select all the equations that match the diagram?

The given parameters are

So, we have

x + 5 + x + 5 + x + 5 = 18

Evaluate the sum

So, we have

3x + 15 = 18

Factor out 3

So, we have

3(x + 5) = 18

Divide both sides by 3

The inequality form of the given expression is:

The interval notation is : (−∞,−8)∪(0,∞)

Given, the expression is |x + 4| - 4 > 0

An inequality is a relationship that shows a non-equal comparison between two numbers or mathematical expressions.

Isolate the variable by dividing each side by factors that don't contain the variable.

⇒  |x + 4| - 4 > 0

⇒  |x + 4|  > -4

Remove mod.

⇒ x + 4 > -4 or  x - 4 > -4

⇒ x > -4 -4 or x > -4 +4

⇒ x <-8 or x > 0

Hence the internal notation is :

Answers

The value of x based on the information given about the circumference is 2.24.

How to illustrate the information?

It should be noted that the circumference is calculated as:

where

π = 3.142

r = radius = 4x - 5.

Circumference = 25

Therefore, circumference = 2πr.

(2 × 3.142)(4x - 5) = 25

6.284(4x - 5) = 25.

25.136x - 31.42 = 25

Collect like terms

25.136x = 25 + 31.42

25.136x = 56.42

x = 56.42 / 25.136

x = 2.24

ar travels on a straight, level road. (a) Starting from rest, the car is going 38 ft/s (26 mi/h) at the end of 4.5 s. What is the car's average acceleration in ft/s²?​

Answers

The car's average acceleration is 8.44 ft/s².

Acceleration is defined as the rate of change of velocity per unit time. It is usually denoted by the letter a.

Here, we are given that a car travels on a straight road. Starting from rest, the car is going at 38 ft/s (26 mi/h) at the end of 4.5 s.

Acceleration of an object can be calculated using the given formula-

acceleration = velocity/ time

Here, the velocity of the car will be 38 ft/s

and the time is equal to 4.5 seconds.

Thus, putting these formulas in the equation, we get-

acceleration of the car = 38/ 4.5

= 380/ 45

= 8.44

Thus, the car's average acceleration is 8.44 ft/s².

We can start by adding the two equations which together are equal to 180.

15x + 2 + 10x + 3 = 180

We can simplify it to 25x + 5 = 180

Now we can subtract 5 from both sides to get

25x = 175

Then we can divide both sides by 25 to get x = 7

Now we can plug in x for both angles

Corresponding angles are defined as any pair of angles which on the same side of one or two lines, there is a  cut through by a transversal.

It is also important to note that when a transversal intersects two parallel lines, the corresponding angles of the lines would be equal.

Given the angles;

Angle 2 equals (2x+5) degrees Angle 3 equals 85 degrees

We have that;

Angle 2 = Angle 3

Substitute the values

2x + 5 = 85

collect like terms

2x = 85 - 5

2x = 80

2x/ 2 = 80/ 2

A coordinate plane with a line passing through (negative 2, negative 5), (0, negative 3), and (3, 0).

What is the missing information?

The input of the function, of f(x - 3), is missing.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the function is:

f(x) = x.

The translation is in the input, f(x - 3), meaning that the function is shifted 3 units right and defined by:

f(x - 3) = x - 3.

Hence three points on the graph are:

x = -2, f(x) = -5.x = 0, f(x) = -3.x = 3, f(x) = 0.

Hence the correct description is:
