Mathematics
1 answer:
alisha [4.7K]3 years ago

Answer:

The objective for solving equations for variables is to get the x terms on one side and the non-x terms on the other side.

7) r + sx = t

sx = t - r (Subtract r from both sides)

x = (t - r) / s (Divide both sides by s)

8) m = 2x + n

m - n = 2x (Subtract n from both sides)

(m - n) / 2 = x (Divide both sides by 2)

x = (m - n) / 2 ("Flip" the equation, this is optional but this is how you usually write your answer, it will be in the form x = something.)

9) 4x - 5c = 3c

4x = 8c (Add 5c to both sides; 5c + 3c = 8c)

x = 2c (Divide both sides by 4; 8c / 4 = 2c)

Which equation is a function of x?
alisha [4.7K]

Answer:

If you input a value of x then we get the output f(x) = y, which is the function of x. This is a function of x. Hence, x² = y is a function of x.

The distance from the Earth to the moon is about 239,000 miles. Rewrite the distance in scientific notation.
egoroff_w [7]

Answer:

2.39 x 10^5 miles

Step-by-step explanation:

Although it is not usually written, there is always a .0 at the end of a number unless there is a specific decimal that was given.

So, the number here is 239,000.0 and if you count the number of spaces that the decimal needs to move in order to be in the correct spot for scientific notation (which is always after the first number), there is 5 spaces.

Therefore the answer is 2.39 x 10^5 miles.

IrinaVladis [17]

Answer:

Step-by-step explanation:

i dont have paper with me rn so i cant actually write the equations, but slope intercept is y=mx+b form so all you have to do is find the slopes (y2-y1/x2-x1) and plug a coordinate into point slope form. simplify and rearrange to y=mx+b form. hope this helped
