Answer:

3f = 9

Step-by-step explanation:

[tex]3f + 1 = 10 \\ 3f = 10 - 1 \\ 3f = 9 \\ f = \frac{9}{3} \\ f = 3[/tex]

Answer:

[tex] \sf \: f = 3[/tex]

Step-by-step explanation:

Given equation,

→ 3f + 1 = 10

Now the value of f will be,

→ 3f + 1 = 10

→ 3f = 10 - 1

→ 3f = 9

→ f = 9 ÷ 3

→ [ f = 3 ]

Hence, the value of f is 3.

The parabola g(x) is reasonable because it can be derived of parabola f(x) by rigid transformations.

Parabolas are represented by second order polynomials in vertex form, whose definition is shown below:

y - k = C · (h - k)²

Where:

In this problem we must create the expression for the image of the parabola by means of rigid transformations, that is, transformations that change the parabola without changing Euclidean distances. Most common rigid transformations are listed below:

The procedure is summarized below:

Now we proceed to apply the rigid transformations in that order:

Step 1

y = f(x) → y = f(x - 3)

y = x² → y = (x - 3)²

Step 2

y = f(x - 3) → y - 2 = f(x - 3)

y = (x - 3)² → y - 2 = (x - 3)²

Step 3

y - 2 = f(x - 3) → y - 2 = - f(x - 3)

y - 2 = (x - 3)² → y - 2 = - (x - 3)²

Step 4

y - 2 = - f(x - 3) → y - 2 = - f[0.5 · (x - 3)]

y - 2 = - [0.5 · (x - 3)]²

Finally, we proceed to plot both parabolae by help of a graphing tool.

We can write an equation of a line in slope intercept form when given a graph of a line by using the equation y = mx + c.

There are various forms in which an equation is present. Based on the given equation or graph values, we can determine the form we should use. The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

We first see the point where the line cuts the y-axis, then we calculate the slope of the line using the formula,

Slope= Δy/Δx

Once we get these values, we can substitute them in the equation for our final answer.

An unfair comparison between two numbers or other mathematical expressions is referred to as an inequality. It is most frequently used when comparing the sizes of two numbers on a number line. The attachment contains the graph for each inequality or equation.

A graph is a graphical representation of statistical data or the functional relationship of variables. Graphs can highlight broad trends in the quantitative behaviour of data, which is useful for forecasting. They can, however, be inaccurate and occasionally deceptive as mere approximations.

Most graphs have two axes: one for independent variables and one for dependent variables. A broken-line graph is the most common type of graph, with time serving as the independent variable.

The hourly charge is $4 per hour for the first 3 hours.

The rate then drops to $2 per hour until the end of the 6th hour.  

The hourly rate drops further to $1 per hour between the 6th and 10th  hours.

The maximum price of the bike rental is $30.

Step-by-step explanation:

The slope of the graph corresponds to the hourly rate for the bike rental.

During the first three hours of the bike rental, the price increases by $4 each hour.

Between the 3rd  and 6 th hours, the slope of the graph is 2, which means the hourly rate of the bike rental is $2 per hour.

Between the 6th and 10th hours, the rate is $1 per hour.

After the 10th  hour, the price, P, stops increasing. The maximum price of the bike rental is $30.

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

An equilateral triangle is a triangle that has all it sides and angles equal to each other. Each angle of an equilateral triangle is 60 degrees.

An Isosceles triangle is a triangle that has two of it sides and angles equal to each other. The base angles of an isosceles triangle are equal and the two legs are equal.

Therefore, let's use these principle to find the ∠ABC.

∠DBC = 60 degrees

The radius of the circle is 12.5 cm. So the option b is correct.

In the given question, the diameter of a circle is 25 cm.

We have to find the radius of the circle.

The radius of a circle is the distance a circle's centre from any point along its perimeter. Usually, "R" or "r" is used to indicate it. In almost all calculations containing spheres, this quantity is essential. In terms of radius, a circle's area and circumference are also calculated.

The distance from any circular object's centre to its outermost border or boundary is measured in terms of radius. A radius is a property of not only circles but also spheres, semi-spheres, cones with circular bases, and cylinders with circular bases.

The given diameter = 25 cm.

Now the radius = diameter/2

Radius = 25/2

Radius = 12.5 cm

If the last three digits of a number are divisible by 8, then the number is completely divisible by 8. So we can check the last three digits of a number to know whether they are a multiple of 8.

A multiple of 8 is a number that can be evenly divided by 8 without a remainder. To determine if a number is a multiple of 8, you can divide it by 8 and check if the quotient is an integer (a whole number with no remainder).

For example, to check if the number 96 is a multiple of 8, you can divide 96 by 8 and the quotient is 12, which is an integer, so 96 is a multiple of 8.

Another way to check if a number is a multiple of 8 is to check if the last three digits of the number are 000 or divisible by 8. This is because 8 is a power of 2 (2^3=8), and any number that is a multiple of 8 will be divisible by 2^3, which means it must have 3 trailing zeroes.

A more general method to check if a number is a multiple of any number is by using the modulo operator, which returns the remainder of a division. If x is a multiple of y, then x mod y = 0. Therefore, you can use x % 8 == 0 to check if x is a multiple of 8.

The equation in y = 2x + 8 for the given coordinates.

Finding the equation of a straight line in the coordinate plane is done using the slope-intercept form. A straight-line's equation will be that relationship that:

any place on the line's coordinates must meet.

Any point that is not on the line will not have coordinates that satisfy.

Given coordinates

x   -2      -1         0        1

y    4        6         8       10

equation is given by y = mx + c

m is the slope and c is y-intercept

let x₁ = -2, x₂ = -1

y₁ = 4, y₂  = 6

m = (y₂ - y₁)/(x₂ - x₁)

m = (6 - 4)/(-1 - (-2))

m = 2

so y = mx + c

substitute value of m

y = 2x + c

at x = 0 and y = 8

8 = 2(0) + c

c = 8

equation of line y = mx + c

y = 2x + 8

Hence the equation is y = 2x + 8.

Answer: y = 6x + 20, or E = 6t + 20

Step-by-step explanation:

Taking two points on the graph, (10, 80) and (30, 200), you can find the slope ("E") with the equation (y2-y1)/(x2-x1), which when plugged into the formula would be (200-80)/(30-10) = 120/20 = 6. To get your "t", you would plug this back into the formula y=mx+b along with any point on the graph, which would be:

80 = 6(10) + b

80 = 60 + b

b = 20

So the final equation should be y = 6x + 20
