Explain whether each is a linear equation

y = 1 - x

Answers

Answer 1

Answer:

In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable. If the variables have other names, yet do have a dependent relationship, the independent variable is plotted along the horizontal axis

:)

Answer 2

Answer:

This should be considered a linear substitution because you can substitute this equation into y in another linear equation to find the answer or the solution to the linear equation

Clark Kent and Lois Lane were laying on a blanket, enjoying a relaxing picnic when Clark noticed a giant asteroid approaching Earth. Clark calculates the angle of elevation of the asteroid's approach to be 62°. Lois' penthouse apartment is also in the pathway of the asteroid's approach, 100 feet above ground. Clark's eye is 75 feet from the base of Lois' building. Will the asteroid take out Lois' penthouse apartment?

Answers

Answer:

The asteroid will not take out Lois' penthouse.

Step-by-step explanation:

Since the distance between Clark and the base of Lois' building is x = 75 feet and the asteroid is at an angle of elevation of Ф = 62°. These two components form a right-angled triangle with opposite side h which is the height of the asteroid above the ground.

So, by trigonometric ratios,

tanФ = h/x

h = xtanФ

h = 75 ft × tan62°

h = 75 ft × 1.8807

h = 141.1 feet

Since h = height of asteroid above the ground = 141.1 feet is greater than height of the penthouse above the ground = 100 feet, the asteroid will not take out Lois' penthouse.

Answers

Answer:

B, 4

Step-by-step explanation:

To do this you can use the Pathagaryos thereom a^2+b^2=c^2

So we have (x-2)^2+x^2=20

We can expand (x-2)^2 and get

x^2-4x+4

so we have x^2 -4x +4 + x^2=20

We can combine like terms and subtract 20 from both sides to get

2x^2-4x-16=0

We can factor this and get (2x+4)(x-4)

which means that x=4 and -2

Obviously the length can't be a negative and so we reject x= -2 and we get x=4

We can double check it and see that

(4-2)^2+4^2=20

and it does

11) -6x – 9y = 0
-24x = 36y

Answers

Answer:

x = 0, y = 0

or

(0, 0)

Step-by-step explanation:

-24x - 36y = 0

divide the equation by 4

-8x - 9y = 0

-6x - 9y = 0

multiply the second equation by -1

6x + 9y = 0

add them together

-8x - 9y = 0

6x + 9y = 0

-2x = 0

x = 0

substitute into the second equation

-8 * 0 - 9y = 0

-9y = 0

y = 0

Move the numbers to the blanks to order them from least to greatest value.
|-2|

-0.89
1/2

Answers

-0.89, 0.4, 1/2, 9/8, |-2|

Answer:

This is from least to greatest.

-0.89, 0.4, 1/2, 9/8, (-2)

Step-by-step explanation:

-0.89 is negative so it is the least because the other numbers are positive.

0.4 is next because 0.4 is smaller than 0.5 because 1/2 = 0.5

Then 1/2 because 9/8 is more than 1/2 of 8 which would be 4, but 9/8 is bigger than 4/8.

Finally the biggest number is (-2) Because the absolute value of -2 is 2, and 2 is a whole number, which is bigger than the decimals and fractions.

And of course 9/8 is equal to 1 1/8 but 2 is bigger than 1 1/8

Find the slope of the line y = 7x – 2.

Answers

the slope 7 and the y int. is -2 in case you also wanted to know

Answer:

m = 7, b = -2

Step-by-step explanation:

The equation y = 7x - 2 is written in y = mx + b, also known as slope intercept.

In slope-intercept, m is the slope and b is the y-intercept.

m = coefficient of x

b = constant

Similarly,

m = 7

b = -2

Hence, m = 7 and b = -2.
