Answer:

Answer:

x = 12 is the x-axis intercept

Step-by-step explanation:

'x-intercept'   is short for  'x-axis intercept'  <==== when the graph crosses the x axis, y = 0      so put y = 0   in the equation

y = -2/3 x + 8

0 = -2/3 x + 8

-8 = - 2/3x

x = 8 * 3/2 = 12

No. The pace of change affects the y-value, therefore having a higher beginning value does not guarantee it. The output may decrease if the function with the bigger beginning value has a slower rate of change.

This is further explained below.

Generally, No. Even if the function had a higher beginning value, it does not always follow that it would always have a higher y-value. This is because the y-value also relies on the rate of change.

In conclusion, If the function with the higher beginning value has a slower rate of change, it is possible that the output may become smaller at some time in the future as a consequence of this.

The fundamental guidelines and procedures to simplify any algebraic statement are as follows:By multiplying factors, remove any grouping symbols like brackets and parenthesis.

If the words contain exponents, use the exponent rule to eliminate grouping.Add or subtract like terms to combine them.

Simplify: -42 30(cubed) / 12 10 (cubed)?

By removing the denominators, convert fractions to integers.

Because the denominators of our two fractions differ, we must calculate the Least Common Denominator and rewrite our fractions using the common denominator as needed. LCD(-42/30, 12/10) = 30

Now that the denominators of our two fractions are similar, we may multiply them both by 30 to get rid of the denominators.

The final result is: -42/30: 12/10 = -42: 36

With the highest common factor, attempt to further reduce the ratio (GCF).

GCF is 6 for -42 and 36.

Divide both terms by the GCF, 6, as follows: -7 36 6 = 6; -42 6 =

By dividing both parts by the GCF = 6, the ratio -42:36 can be reduced to its smallest terms: -42:36 = -7:6.

Therefore:

-42/30 : 12/10 = -7 : 6

The two equations are : 6x + m = F

and 6x + 1.8 m = F

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. (b)

Let the total time be x

Given distance Zarela travels is m

Thus the total cab fare = F

Therefore the equation becomes;

6x + m = F

In the second part of the question it is given that Zarela travels for 1.8 mile

thus the equation becomes

6x + 1.8 m = F

The distance it travel in 17litres petrol: 8.024km

What is Distance?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.

Given,

The distance traveled in 201 petrol = 95km

The distance traveled in 1 liter = 95/201

                                                  = 0.472km

Now, we have to find out how many km does it travel in 17liter:

The distance traveled in 17liters = 17 x 0.472

                                                     = 8.024km

The parabola's equation is y = -x2 + 12x - 27.

A parabola is a point's location where the focus and a fixed point's distance from a fixed line, known as the directrix, are the same.

A parabola's equation is in quadratic form.

Thus, it is stated as:

Y = Ax2, Bx, and C

Located at (3, 0):

0 = a(3²) + b(3) + c

9a + 3b + c = 0 (1) (1)

Located at (9, 0):

0 = a(9²) + b(9) + c

81a + 9b + c = 0 (2) (2)

Located at (10, -7):

-7 = a(10²) + b(10) + c

100a + 10b + c = -7 (3) (3)

Equations 1, 2, and 3 are solved to yield: a = -1, b = 12, and c = -27.

Consequently, the parabola's equation is y = -x2 + 12x - 27.

Step-by-step explanation:

3x^2 + x - 5 = 0

3(x^2 + 1/3x) - 5 = 0

Completing the square on the expression in the parentheses:

3[(x + 1/6)^2 - 1/36) - 5 = 0

3(x + 1/6)^2 - 1/12 - 5 = 0

(x + 1/6)^2 = 61/12 / 3

(x + 1/6)^2 = 61/36

Answer:

x = 75

Step-by-step explanation:

The triangle on the right is an equilateral triangle. This means each angle is 60 degrees.

The bottom angle which goes over both triangles is marked as a right angle (90 degrees). Given that the part of that angle in the equilateral triangle is 60 degrees, the rest of the angle (i.e. the part of the angle in the other triangle) is 30 degrees.

It is implied by the markings that the angle x = the other angle at the top (although this should be clearer). Assuming this is the case, we can use the rule that angles in a triangle sum to 180 degrees, to say that:

x + x + 30 = 180

Combine like terms, rearrange and simplify:

2x + 30 = 180

2x = 150

x = 75

Dimensions of envelope will be Length will be (x + 3) = (9 + 3) = 12 and Breadth will be x = 9.

Envelope can be considered as the shape of rectangle.

Rectangle has length and breath which can be considered as the sides of envelope.

Now we have given one side of envelope is 3 inches longer than the other side of envelope.

let side of envelop be x inches than other side will be (x + 3) inches.

Now we have also given that the area of envelop is 108 in².

The Area of rectangle = (length)(breadth).

let length of envelop be (x+3) as its bigger than its breadth x.

∴ Substitute area of rectangle with the area of envelope.

∴ (x + 3)(x) = 108.

∴ x² + 3x = 108.

∴ x² + 3x - 108 = 0.

∴ x² + 12x -9x - 108 = 0

∴ x(x + 12) -9(x +12) = 0

∴ (x-9) (x +12) = 0

∴ (x-9) = 0 and (x +12) = 0

∴ x = 9 and x = -12

Now as dimensions cannot be negative ∴ x = -12 is rejected.

∴ x = 9 is considered

∴ Length will be (x + 3) = (9 + 3) = 12.

∴ Breadth will be x = 9.
