Which of the following is a linear function?

Mathematics

KIM [24]2 years ago
6 0

Answer:

\bold{y = 3x + 2}

Step-by-step explanation:

In a linear equation, y=mx+b, the "m" is identified as the slope, while the b is where you <u>b</u>egin, the coefficient: y-intercept.

Now, with that said, let us look at each option, and see which one matches the linear equation.

<u>Option 1</u>

<em>One over three x = y - 3</em>

\frac{1}{3}x=y-3

As you can see, the y should be in front of the equation. And the -3 should be next to x.

<u>Option 2</u>

<u></u>y = 3x + 2<u></u>

This equation is a  linear equation: the y is in the right place, the coefficient is right next to x, and where you begin is at the right place. If you look at this equation, and the linear equation, you will notice they both match.

<u>Option 3</u>

<u />y = 6\times2

The equation does not make sense in terms of linear equations, first off all. There is nothing to show it is a linear equation, except from the y. It is the same thing as just adding two numbers and putting an equal sign and y in front of it, which is not a linear equation.

<u>Option 4</u>

y = two over three x

y = \frac{2}{3}x

There is no coefficient in this equation, therefore, it is not a linear equation.

a windowpane is 5.7 Inches by 7.1 inches. what is the distance between opposite corners of the windowpane? if necessary, round t
nikitadnepr [17]

Answer:

the distance is 9.1 inches (please give brainliest)

Step-by-step explanation:

we must use the pythagorean theorem:

5.7^2 + 7.1^2 = c^2

(c being the distance being the two corners)

c^2 = 82.9

c = sqrt(82.9) ≈ 9.1

A number, x, rounded to 2 significant figures is 1300<br>Write down the error interval for x.​
nikitadnepr [17]

Answer:

[1250,1350).

Step-by-step explanation:

It is given that a number, x, rounded to 2 significant figures is 1300.

It is possible if,

1. The value of x is greater than of equal to 1250 and less than or equal to 1300.

i.e., 1250\leq x\leq 1300     ...(1)

2. The value of x is greater than of equal to 1300 and less than 1350.

i.e., 1300\leq x       ...(2)

On combining (1) and (2), we get

1250\leq x < 1350

1350 is not included in the error interval for x.​

Interval notation is [1250,1350).

Therefore, the error interval for x is [1250,1350).

Answer:

Here is the full proof:

AC bisects ∠BCD      Given

∠CAB ≅ ∠CAD          Definition of angle bisector

DC ⊥ AD                    Given

∠ADC = 90°               Definition of perpendicular lines

BC ⊥ AB                    Given

∠ABC = 90°               Definition of perpendicular lines

∠ADC ≅ ∠ABC          Right angles are congruent

AC = AC                     Reflexive property

ΔCAB ≅ ΔCAD          SAA

BC = DC                     CPCTC
