What is 2/5 y + 1/5 x -0.2y-6+(-2)

Answers

Answer 1

Answer:

[tex]\frac{y}{5} + \frac{x}{5}-8[/tex]

Step-by-step explanation:

1)  Simplify 2 /5y to 2y/5.

[tex]\frac{2y}{5} + \frac{1}{5} x-0.2 y-6-2[/tex]

2) simplify 1/5x to x/5.

[tex]\frac{2y}{5} +\frac{x}{5} -0.2y-6-2[/tex]

3) Collect like terms.

[tex](\frac{2y}{5} -0.2y) + \frac{x}{5} +(-6-2)[/tex]

4) Simplify.

[tex]\frac{y}{5}+ \frac{x}{5} -8[/tex]

Therefor, the answer is y/5 + x/5 -8.

log x - log 6 = 2 log 4

Answers

log(x) - log(6) = 2 log(4)

Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):

log(x / 6) = 2 log(4)

Rewrite the right side, using the property n log(a) = log(aⁿ ):

log(x / 6) = log(4²)

log(x / 6) = log(16)

Cancel the logarithms (i.e. take the exponential of both sides):

exp(log(x / 6)) = exp(log(16))

x / 6 = 16

Solve for x :

x = 6 × 16

x = 96

Decide which of the two points lies on the graph of the line.

1. X + Y = 8
A. (2,4) B. (2,6)

2. X = 4
A.(4,2) B. (2,4)

3. Y = X - 2
A. (4,6) B. (6,4)

Answers

Answers:

B) (2,6)A) (4,2)B) (6,4)

===========================================

Explanations:

For this problem, the x and y coordinates must add to 8. In choice A, we have x+y = 2+4 = 6, which doesn't work. But choice B does work since x+y = 2+6 = 8. Therefore, the point (2,6) is located on the line x+y = 8. The equation x+y = 8 is equivalent to y = -x+8.The x coordinate must be equal to 4. The y coordinate can be anything you want. The point (4,2) is on this line, while (2,4) is not. Another point on this line is (4,1). The line is completely vertical.If we plugged the x & y coordinates of choice A into the equation, we get 6 = 4-2 which then becomes 6 = 2 and that's a false statement. That rules out choice A. If we try choice B, then we get 4 = 6-2 which becomes 4 = 4. We get a true statement so choice B is the answer.

the function of C gives the percentage of homes using only cell phone service X years after 2004 explain the meaning of each statement.

1. C(10)=35
2. C(x) = 10
3. how is C(10) different from C(x) = 10?

Answers

Answer:

Step-by-step explanation:

1. C(10)=35  is the percentage of homes using only cell phone service 10 years after 2004, that is, after 2014.

2. C(x) = 10  is the percentage of homes using only cell phone service x years after 2004.  We must find x.

3. how is C(10) different from C(x) = 10?

In C(10), 10 measures time in years and is the independent variable here; C10) is the dependent variable.  See (2), above.  In C(x), x is the (unknown) independent variable, whereas 10 is the output vaue, the dependent variable.
