Two brothers, Mark and Walter, each inherit $20000. Mark invests his inheritance in a savings account with an annual return of 2

Igoryamba

Answer:

$720

Step-by-step explanation:

$20000 - 100%

$x. - 2.5%

x=(20000*2.5)/100=500

20000+500=$20500 in one year (Mark)

20000 - 100

x. - 6.1

x= (20000*6.1)/100 = 1220

20000+1220= $21220 (Walter)

21220-20500= $720 more (Walter will have after 1 year)

what is the equation in slope intercept form of the line that passes through the point (-4,47) and (2,-16)

Vilka [71]

The slope-intercept form:

$y=mx+b$

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-4, 47) and (2, -16). Substitute:

$m=\dfrac{-16-47}{2-(-4)}=\dfrac{-63}{6}=-\dfrac{63:3}{6:3}=-\dfrac{21}{2}$

Therefore we have:

$y=-\dfrac{21}{2}x+b$

Put the coordinates of the point (2, -16) to the equation:

$-16=-\dfrac{21}{2}(2)+b\\\\-16=-21+b\qquad\text{add 21 from both sides}\\\\5=b\to b=5$

Answer: $\boxed{y=-\dfrac{21}{2}x+5}$

\log_{4} x + \log_{4} (x+5) = 6

irina1246 [14]

log(4)x + log(4)(x + 5) = 6
log(4)x + log(4)x + log(20) = 6
 log(8)x + log(20) = 6
 - log(20) - log(20)
 log(8)x = 6 - log(20)
 log(8) log(8)
 x ≈ 0.999
