ASAP SOLVE THE SLOPE

The slope is one half. You can get this by seeing that the x intercept is -8 and the y intercept is four, meaning rise = 4 run = 8, and because to calculate slope is rise/run, 4/8 = 1/2

8 + (-10) just confused lol

Answers

8+(-10) is like 10-8 except backwards so how i do some problems is like that and then add a negative sign; so say if i were doing 8+(-10), i would do 10-8 which equals 2 and then since 10 is bigger than 8 and it’s a negative number, i would put -2 as my answer

the equation of line L is y=5x+1

Answers

Consider the complete question is "The equation of the line [tex]L_1[/tex] is y=5x+1 and the equation of line [tex]L_2[/tex] is 2y-10x+3=0. How can you show that these two lines are parallel?"

Given:

Equation of [tex]L_1[/tex] is [tex]y=5x+1[/tex].

Equation of [tex]L_2[/tex] is [tex]2y-10x+3=0[/tex].

To show:

The these line as parallel.

Solution:

We have,

[tex]y=5x+1[/tex]        ...(i)

[tex]2y-10x+3=0[/tex]      ...(ii)

Equation (ii) can be written as

[tex]2y=10x-3[/tex]

[tex]y=\dfrac{10x-3}{2}[/tex]

[tex]y=\dfrac{10x}{2}-\dfrac{3}{2}[/tex]

[tex]y=5x-\dfrac{3}{2}[/tex]           ...(iii)

Slope intercept form of a line is

[tex]y=mx+b[/tex]          ...(iv)

where, m is slope and b is y-intercept.

On comparing (i) with (iv), we get slope of line [tex]L_1[/tex].

[tex]m_1=5[/tex]

On comparing (iii) with (iv), we get slope of line [tex]L_2[/tex].

[tex]m_2=5[/tex]

Since, [tex]m_1=m_2[/tex], therefore, lines [tex]L_1[/tex] and [tex]L_2[/tex] and parallel because slope of two parallel lines are always equal.

Hence proved.

Step-by-step explanation:

A number, rounded to 2 decimal places, is equal to 3.84.
Write down the lower and upper bounds of the number.

Answers

Answer:

Lower bound = 3.835

Upper bound = 3.844

Step-by-step explanation:

Given,

A number rounded to 2 decimal place = 3.84

In other to obtain the least and greatest number, we are mostly concerned about the third digit after the decimal point.

Knowing that numbers 5 and above are rounded to 1 while numbers below 5 are rounded to Zero.

Hence, the lower bound should have its original hundredth value as (4 - 1) such that it becomes 4 when the thousandth value is rounded to 1.

Lower bound = 3.835

The upper bound should have its thousandth value as one which is rounded to Zero, just a point below 5

Upper bound = 3.844
