Answer:

1. x=4

2. x=15

Step-by-step explanation:

1. Add '-42' to each side of the equation.

42 + -42 + -2x = 50 + -42

Combine like terms: 42 + -42 = 0

0 + -2x = 50 + -42

-2x = 50 + -42

Combine like terms: 50 + -42 = 8

-2x = 8

Divide each side by '-2'.

x = -4

Simplifying

x = -4

2.

Add '35' to each side of the equation.

-35 + 35 + 7x = 70 + 35

Combine like terms: -35 + 35 = 0

0 + 7x = 70 + 35

7x = 70 + 35

Combine like terms: 70 + 35 = 105

7x = 105

Divide each side by '7'.

x = 15

Simplifying

x = 15

Answer:

  • positive
  • negative

Step-by-step explanation:

The thrust of the question is to make sure you understand that increasing the y-coordinate of a point will move the point upward, and decreasing it will move the point downward.

That is adding a positive value "k" to x^2 will move the point (x, x^2) to the point (x, x^2+k), which will be above the previous point by k units.

If k is subtracted, instead of added, then the point will be moved downward.

The blanks are supposed to be filled with <u> positive </u>, and <u> negative </u>.

_____

<em>Comment on the question</em>

The wording of the statement you're completing is a bit odd. If k is negative (-2, for example), this statement is saying the graph is translated down -2 units. It is not. It is translated down |-2| = 2 units. The direction of translation depends on the sign of k. The amount of translation depends on the magnitude of k.

If you thoroughly understand (x, y) coordinates and how they are plotted on a graph, it should be no mystery that changing the y-coordinate will change the vertical position of the graph.

-2 is the answer! Remove the parentheses then move the terms. After that, collect the terms and calculate. Lastly, divide both sides.

Find the ratio of x to y is 5y=3x
Colt1911 [192]

Answer:

\frac{x}{y} = \frac{5}{3}

Step-by-step explanation:

given 5y = 3x ( divide both sides by 3 )

\frac{5}{3} y = x ( divide both sides by y )

\frac{5}{3} = \frac{x}{y}

jolli1 [7]
Use the attached formula.
exp = [log (total / principal) / n*years]
where "n" is compounding periods per year
exp = [log (7,194.66 / 2,978.41) / (365*21)
exp = log ( <span> <span> <span> 2.4156042989 </span> </span> </span> ) / 7,665
exp = log ( <span> <span> 2.4156042989 </span> </span> ) / 7,665
exp = 0.38302579382 / 7,665
exp = <span> <span> <span> 0.00004997074935681670 </span> </span> </span>

rate = (10^exp -1)* n
rate = (10^<span>0.00004997074935681670 -1) * n
</span>rate = <span><span>(1.0001150685 </span> -1) * 365
</span>rate = <span>(.0001150685) * 365</span>
rate = <span> <span> <span> 0.0420000025 </span> </span> </span>
rate = <span>4.20000025 %
rate = 4.2 %

Yes, it's just that easy.  LOL
