Well it’s easy x=3

Because if you see power to any number of you need to multiply just add the powers for example 2^3 • 2^4 = 2^7.

You don’t need to multiply #2. And just add up the ^

Which statement describes the end behavior of the exponential function f(x) = 2^x-3?

Travka [436]

Lim 2^x-3 = lim 2^(1/x^3) = 2^(1/inf) = 2^0 = 1

x -> infinity

The function approaches 1

Do 18/24 and 10/15 have the same value? Explain your answer in complete sentences.

LenaWriter [7]

Answer:

Step-by-step explanation:

We can either cross multiply or turn into decimal form to see if they have the same value.

I will be showing both.

Cross Multiply: Decimal Form:

$\frac{18}{24} \;[\;\;] \frac{10}{15}$ $\mathrm{To\;turn\;fraction\;into\;decimal\;just}$

$18\times15=270$ $\mathrm{Divide\;numerator \;by \;denominator\;}$

$24\times10=240$ $\mathrm{18\div24=0.75}$

$\frac{18}{24} \;[ > ] \frac{10}{15}$ $\mathrm{10\div15=0.66666666666}$

$\mathrm{As\;a\;result\;we\;can}$ $0.75 > 0.66666666666$

$\mathrm{conclude\;that\;\frac{18}{24} \;is\;greater\;than\;\frac{10}{15}}$ $\frac{18}{24} \;[ > ] \frac{10}{15}$

We can conclude that 18/24 and 10/15 are not the same.

Complete the equation of the line whose slope is 5 and y intercept is (0,4)

irina1246 [14]

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)

Solution:

Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)

The equation of line in slope intercept form is given as:

y = mx + c ---- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, slope = m = 5

y intercept is (0, 4)

So, c = 4

Substitute c = 4 and m = 5 in eqn 1

y = 5x + 4

Thus the equation of line is found

Answer:

$-2\sqrt{3}+8\sqrt{5}$

Step-by-step explanation:

$-2\sqrt{3} -\sqrt{5} +3\sqrt{9\times5} = -2\sqrt{3} -\sqrt{5} +3\sqrt{9}\times\sqrt{5} = -2\sqrt{3} -\sqrt{5} +9\sqrt{5} = -2\sqrt{3}+8\sqrt{5} \\$
