how do you differentiate linear equation from those equatipn which are not linear?​

Answers

Answer:

the x

Step-by-step explanation:

Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).

When you look at graphs that aren't linear, the x doesn't stand alone in the equation.

Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.

To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.

[tex]\frac{11}{8}[/tex]Answer:

55 in by 40 in

Step-by-step explanation:

The perimeter (P)  of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width )

Here l = [tex]\frac{11}{8}[/tex] y and w = y with P = 190

2y + (2 × [tex]\frac{11}{8}[/tex] y ) = 190

2y + [tex]\frac{11}{4}[/tex] y = 190 ( multiply through by 4 to clear the fraction )

8y + 11y = 760 , that is

19y = 760 ( divide both sides by 19 )

y = 40

Thus l = [tex]\frac{11}{8}[/tex] × 40 = 11 × 5 = 55 in and w = 40 in

Answers

Answer:

b = d/(2ac)

Step-by-step explanation:

10abc - 2d = 3d

Add 2d to each side

10abc - 2d+2d = 3d+2d

10 abc = 5d

Divide each side by 10ac

10 abc/ (10ac) = 5d/10ac

b = d/(2ac)

(x−92)2−694. Explanation: the equation of a parabola in vertex form is.

Complete the statements below that show y = x2 + 2x - 1 being converted to vertex form.

Form a perfect-square trinomial.
y = x2 + 2x +
− 1−

Answers

We want to complete the steps to convert the given quadratic equation into vertex form.

Eventually we will get:

y = (x + 1)^2 - 2

Vertex form of a quadratic equation.

For a quadratic equation with the vertex (h, k), the vertex form is:

y = a*(x - h)^2 + k

Here we start with:

y = x^2 + 2x - 1

1) First, we complete the perfect-square trinomial, we need to add and subtract 1 to get that:

y = x^2 + 2x - 1 + 1 - 1

2) Now we rewrite the equation to be able of completing squares:

y = (x^2 + 2x + 1) - 1 - 1

y = (x^2 + 2x + 1) - 2

3) Now we complete squares

y = (x + 1)^2 - 2

And this is the equation in vertex form, where you can see that the vertex is the point (-1, - 2)

The rate is computed as follows:Single Plantwide Factory Overhead Rate= (Total Budgeted Factory Overhead) (Total Budgeted Plantwide Allocation Base)WoolCorp has been using combing machine hours as its allocation base.The company would like to consider activity-based costing.
