Solve for x. 2000=500e^4x

Misha Larkins [42]

Answer:

A. x = (ln(4))/4

Step-by-step explanation:

2000 = 500e⁴ˣ

(2000)/500 = (500e⁴ˣ)/500

4 = e⁴ˣ

ln(4) = ln(e⁴ˣ)

ln(4) = 4x

(ln(4))/4 = (4x)/4

(ln(4))/4 = x

x = (ln(4))/4

Identify the domain and range of y = 4x - 5 + 3

Zepler [3.9K]

Answer:

$\huge\boxed{\text{Domain:}\ D=\mathbb{R}=(-\infty;\ \infty)}\\\boxed{\text{Range:}\ R=\mathbb{R}=(-\infty;\ \infty)}$

Step-by-step explanation:

y = 4x - 5 + 3 = 4x - 2

It's an equation of a line in the slope-intercept form.

y = 4x - 2 → f(x) = 4x - 2 - it's a lienar function.

The domain of a linear function is the set of all real numbers.

If a slope of linear function is different than 0, then the range is the set of all real numbers.

Help plz answer needed fast

grigory [225]

We just substitute in -12 for x in each one and see if it's true

2(-12)+6 = -24 + 6 = -18, not 30, NOPE

-0.25(-12) - 1 = 3-1 = 2, that worked, CHECK ME

-12 - 8 = -20, CHECK ME

-35(-12) +2 = 422, not -515, NOPE

3(-12+25)=3(13)=39, CHECK ME

Simplify without the absolute value<br> |x+3| ; if x=2

Alja [10]

ANSWER

EXPLANATION

We want to simplify:

$|x + 3|$

when x=2.

We substitute x=2 into the absolute value expression to obtain:

$|2 + 3| = |5|$

The about value of 5 means what is the distance of 5 from zero on the real number line.

$|2 + 3| = |5| = 5$
