\begin{array}{rllll} 
% left side templates
f(x)=&{{  A}}({{  B}}x+{{  C}})+{{  D}}
\\ \quad \\

f(x)=&{{  A}} sin\left({{ B }}x+{{  C}}  \right)+{{  D}}
\end{array}

\qquad if\ {{  D}}\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{{{  B}}}

now... with that template in mind, let's see yours

\bf \begin{array}{llll}
g(x)=&4ln(x)\implies &2(2)ln(x)\\
&\uparrow &\uparrow \\
&A&A
\end{array}

A is twice as large as in f(x), thus the graph shrinks twice as much in g(x)

7th grade math help me pleaseee :)
Gemiola [76]

Answer:

A.  A + B (it'll be negative because they're both negative numbers and adding a negative is the same as subtracting a positive)

B. B - A ( It'll be positive because subtracting a negative is the same as adding a positive, and B is closer to 0 so it's a "bigger" number than A. so, adding A to B will make it positive)

Step-by-step explanation:

The explanations are in parenthesis to the right of the answer. they're kind of confusing, but the answers are correct.

What is 1.859 to the nearest hundredth
Katen [24]
The 5 is in the hundredths place, so you would look at the number before it, which is 9. Since 9 is greater than 4, you will round the 5 up to 6
So it would be 1.86

GEOMETRY PLEASE HELP
marysya [2.9K]

Answer:

see explanation

Step-by-step explanation:

(5)

Since ∠EBA = 90° then ∠ABD = 90° ( straight angle ) and

∠ABC + ∠CBD = ∠ABD, that is

2x + 3x - 10 = 90, simplifying

5x - 10 = 90 ( add 10 to both sides )

5x = 100 ( divide both sides by 5 )

x = 20, thus

∠ABC = 2x = 2 × 20 = 40°

∠CBD = 3x - 10 = (3 × 20) - 10 = 60 - 10 = 50°

(6)

4x - 18 = 3x + 7 ( vertical angles are congruent )

Subtract 3x from both sides

x - 18 = 7 ( add 18 to both sides )

x = 25

7y = 5y + 28 ( vertical angles are congruent )

Subtract 5y from both sides

2y = 28 ( divide both sides by 2 )

y = 14
