Determine whether the lines are parallel or perpendicular or neither. 2x=y−10 and y=−2x

Mathematics

MrRa [10]3 years ago

Put the first equation in slope-intercept form, or y = mx + b. Start by subtracting y from both sides.

2x - y = -10, subtract 2x from both sides.

-y = -10 - 2x

Divide both sides by negative one.

y = 10 + 2x

To find the slope when the equations are in slope-intercept form you look at the coefficient of x. The first equation has the slope of 2 (which we just found), and the second equation has the slope of -2.

Parallel lines have the same slope and perpendicular lines have opposite reciprocal slopes. Since 2 and -2 are neither of these, your answer is neither.

8v^2 +3=35 

8v^2=35-3&#10;&#10; &#10;      Subtract \ 3 \ from  \ both \ sides

&#10;8v^2=32&#10; &#10; 

v^2= \dfrac{32}{8}   Divide \ both \ sides \ by \ 8

v^2=4 

&#10;v=+ \sqrt{4} &#10; &#10;            Take \ the \ square \ root \ of \ both \ sides

&#10;v=+2&#10; &#10;&#10; &#10;                       \ Since \ 2*2=4, \ the \ square \ root \ of \ 4  \ is  \ 2

46.3×0.8 show your work
VLD [36.1K]
To make it easier, remove the decimals, we'll add those later.

462
x   8
-------
3704

multiply each digit of 462 by 8. you get 3704. 

now, since 46.3's decimal is one to the left and .8 is one to the left as well those are 2 place marks

so we move the decimal 2 places to the left in 3704, the answer

and we get 37.04

Which of the following could be the equation of the graph shown below? A. y=-10 B. 2x- 3y= -9 C. y = 3x-2 D. -4x+ 2y= -6
matrenka [14]

Answer:

C. y = 3x - 2

Step-by-step explanation:

Since the y intercept is negative, it is seen in this equation that the b value (the y intercept) is also negative.  Since the slope is increasing upward, we know that the slope is greater than 1 and is going upward, and it matches with the equation since it matches with both of the requirements.

Which statement describes how to determine if a relation given in a table is a function?
const2013 [10]

Answer: B

Step-by-step explanation: A function is a relation in which each input value is paired to exactly one output value.

Technically, if you had the same input value twice and the same output value corresponded to each of those, it would still be a function because you are just repeating what you have twice.

However, most teachers want to think of it as each input value must have exactly one corresponding value to be a function.
