The result of the function f(x)=x+6 when x= -2,0 and 5 is

f(-2)= 4

f(0)= 6

f(5) = 11

The function is f(x) = x+6

The function is an expression that shows the relationship between one variable and another variable. One variable will be independent variable and another variable will be dependent variable.

The given function f(x) = x+6 when x =-2, 0 and 5. Here we have to substitute the values of x in the given function

f(x) = x+6

f(-2) = -2+6

= 4

f(0) = 0+6

= 6

f(5) = 5+6

= 11

Hence, the result of the function f(x)=x+6 when x= -2,0 and 5 is

f(-2)= 4

f(0)= 6

f(5) = 11

Answer:
y-intercept = -7
x-intercept = 3.5

Explanation:
y-intercept: 2x - y = 7 rearranges to y = 2x - 7 and in y = mx + b form, b is the y-intercept.

x-intercept: To find x-intercept, substitute y with 0 and solve for x. You get x = 3.5.

The function f(17) represent your friend paid for 17 rides and had $42.75 left over.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

Let f(x) represent the amount that the rider has left over after x rides.

f(x) = -1.25x + 64

f(17) = -1.25(17) + 64 = 42.75

f(17) = $42.75

The rotation of the triangle is shown with the new coordinates N' = (3, -7), O' = (-4,-5) and W' = (-1, -1).

What are coordinates?A pair of numbers that use the horizontal and vertical separations from the two reference axes to describe a point's location on a coordinate plane. Typically represented by the x-value and y-value pair (x,y).

So, a point (x, y) becomes (-y, x) if it is rotated 90° anticlockwise with respect to the origin.

Since, N = (-7, -3) ⇒ N' = (3, -7)O = (-5, 4) ⇒ O' = (-4,-5)W = (-2, 1) ⇒ W' = (-1, -1)

(Refer to the image attached below)

The number of turns gear B will make is 8.25 turns

How to find the number of turns gear B will make

Given data

Gear A turns clockwise and has 54 teeth

Gear B turns counterclockwise and has 36 teeth

gear A makes 5.5 rotations

One of the gears is driving the other hence the distance covered by each of the gears is constant.

The distance is the product of the number of rotations and the number of teeth and this should be a constant

Therefore, let the number of rotations of gear B be x

54 teeth * 5.5 rotations = 36 teeth * x rotations

x rotations = ( 54 teeth * 5.5 rotations ) / 36 teeth

x rotations = 54/36 * 5.5

x rotations = 1.5 * 5.5

x rotations = 8.25

We can therefore say that gear B will make 8.25 rotations

The sequence that contains all the given terms is:

aₙ = -18 + 6*n

Then the correct option is C.

Which sequence can be used to find the n-th term?

Here we have the elements:

a₃ = 0

a₄ = 6

a₅ = 12

a₆ = 18

a₇ = 24

So each term adds 6 to the previous one, so trivially the relation is of the form:

aₙ = aₙ₋₁ + 6

Now we need to find the first term.

We can rewrite the above equation as:

aₙ₋₁ = aₙ - 6

Then we willget:

a₂ = a₃ - 6 = 0 - 6 = -6

a₁ = a₂ - 6 = -6 - 6 = -12

a₀ = a₁ - 6 = -18

Then the sequence is:

aₙ = -18 + 6*n

What are angles?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given Data

∠R = 130°

As PR is the same line

So. angles of the line is 180°.

∠Y + ∠R = 180

∠y = 180 - 135

∠y = 45°

Now, PQ is the straight line

The relation on the table of values is a linear model,

The total monthly pay is $10850 when he sells 23 cars in one monthThe number of cars is 14 if the gross pay is $6,800

How to determine if the relation is linear?

The table of values is given as

Number cars sold 5 6 7 8 9 10

Salary 2750 3200 3650 4100 4550 5000

On the table of values, we can see that:

As the number of cars increase by 1, the salary increases by 450

This means that the table has a constant rate of 450

Relations that have a constant rate are linear relations

Hence, the table of values is a linear relation

The total monthly pay

In (a), we have

Slope, m = 450

A linear equation is represented as

y = m(x - x1) + y1

So, we have

y = 450(x - 5) + 2750

Evaluate

y = 450x + 500

When the number of cars is 23, we have

y = 450 x 23 + 500

Evaluate

y = 10850

Hence, the total monthly pay is $10850

The number of cars

Here, we have

y = 6800

This gives

450x + 500 = 6800

This gives

450x = 6300

Evaluate

x = 14

Hence, the number of cars is 14

The number of gigabytes Salma can use while staying in her budget is less than 4.

What is meant by the term inequality?

In mathematics, an inequality is a connection between two expressions and values that aren't equal to each other.

Rule 1: Once inequalities are linked, they can be crossed. As a result, if an is greater than b and b is higher than c, a will be greater than c as well.Rule 2: When you swap the values, this same sign also flips.Rule 3: An inequality could be either > or, but not both at the same time.

As per the given question;

The total budget of Salma is $75.

The flat cost is $55.

The cost per gigabytes is $5.

Let the number of gigabytes used be 'x'.

Then, the inequality becomes.

55 + 5x < 75

Subtracting 55 from both sides.

55 + 5x - 55 < 75 - 55

5x < 20

Divide both sides by the 5

What does probability mean in math?

Probability is a way to gauge how likely something is to happen. Many things are hard to predict with complete certainty. We can only forecast how likely an event is to occur using it, or how likely it is to occur.

The probability is typically defined as the proportion of positive outcomes to all outcomes in the sample space. Probability of an event P(E) = (Number of favourable outcomes) is how it is stated (Sample space).

based on the facts provided;

p(0) = p(w,w)

= 0.29² = 0.0841

p(1) = p(t, w+t) + p(w, t)

= 2p(w,t) +p(t,t) = 2·.29·.37 + .37² = 0.3515

p(2) = p(f, w+t+f) +p(w+t, f)

= 0.16(2(.29+.37)+.16) = 0.2368

p(3) = p(s, w+t+f+s) +p(w+t+f, s)

Step-by-step explanation:

At 1 hour, 3 hours and 6.5 hours she travels 36 miles, 108 miles and 234 miles respectively using the concept of average speed of an object.

As per the question statement, Clare covers a distance of 0 miles, 72 miles, 144 miles and 216 miles in 0 hours, 2 hours, 4 hours and 6 hours respectively.

We are supposed to find out the distance travelled by her in 1 hour, 3 hours and 6.5 hours.

We will use the concept of average speed of an object which is as follows

average speed = total distance divided by the total time taken

average speed = 216/6 = 36 miles per hour

Hence at 1 hour, distance = 1 * 36 = 36 miles

at 3 hours, distance = 3 * 36 =108 miles

at 6.5 hours, distance = 6.5 * 36 = 234 miles
