What does 45 - 4x equal

1 answer:

7 0

Let y = 0 to find the x-intercept(s).

0 = 45 − 4x

*Then subtract 45 from both sides*
-45 = -4x

*Next, DIVIDE both sides by -4*

-45
—— = x
-4

*NEXT, realize that TWO NEGATIVES MAKE A POSITIVE *

45. 4
——— = x {FLIP} x=——-
4. 45.

y-Intercept

Let x = 0 to find the y-intercept(s).

y = 45 −4(0)

NEXT, SIMPLIFY:

y=45

Smoothing a time series of observations A. is a form of statistical cheating. B. allows statisticians to use less data than woul

DedPeter [7]

Answer:

D. is used to reveal an underlying pattern in the data.

Step-by-step explanation:

Smoothing a time series is achieved when a computer uses some pre-programmed calculation methods to remove noise from large volumes of data. Smoothing helps a user detect patterns in a set of data, thus making it possible to make future predictions. For example, smoothing can be used in the prediction of the rise and fall of stock prices. This helps the traders to have an idea of what to expect in the cost of trading.

Although smoothing reveals the patterns in a set of data, it provides no explanation as to why it is so. It is left to the researcher to draw conclusions as to the reasons for the patterns.

We are driving to Las Vegas. The sign says that it is one hundred forty-five miles to Las Vegas.

nata0808 [166]

Answer:

233.35488 km (Rounded to 233 km)

Step-by-step explanation:

If you convert miles to kilometers then you would use this conversion factor:

1 mile = 1.609344 km (or 1.61 km)

so in this case,

145 mile = 1.609344 km x 145

145 mile = 233.35488 km

I could also round it to 233 km.

Since your on a trip... i hope u enjoy ur journey to Las Vegas!

What is the measure of angle D

Ugo [173]

Answer:

52 degrees

Step-by-step explanation:

A triangle's angles all add up to 180 degrees so we can create this equation:

x + 20 + 3x + 32 = 180

Combine like terms.

x + 3x + 20 + 32 = 180

4x + 52 = 180

Subtract 52 from both sides.

4x = 128

Divide.

128 / 4 = 32

x = 32

Plug in the value of x.

x + 20

32 + 20

Angle D is equal to 52 degrees.

Please inform me of any mistakes.
