Write an equation of a line that has the same slope as 2x – 5y = 12 and the same y-intercept as 4y + 24 = 5x.

Alekssandra [29.7K]

In ax+by=c form
slope=-a/b

y intercept is when x=0

sloope of 2x-5y=12 is -2/-5=2/5

y intercept of 4y+24=5x
4y+24=5(0)
4y+24=0
4y=-24
y=-6
y int=-6

y=mx+b
m=slope
b=y intercept
y=2/5x-6

Find the value of f'(4) when<br> f(x)=5/3x^3/2+8x^1/2

Gala2k [10]

To figure this out plug in 4 for x

f(4)=5/3(4)^3/2+8(4)^1/2 = 5/3(8) + 8(2)
= 5/3 x 8 + 16 = 40/3 +16 = 88/3

Hope this helps!

100 gives

lisov135 [29]

Answer:

Step-by-step explanation:

a) P = N 150000

R = 5%

T = 5 years

Plug in the values P,R & T in the formula

I = PRT

$I=150000*\frac{5}{100}*4\\\\= 1500 * 5 * 4\\$

I = N 30000

b) I = N 16100

R = 7%

T = 5 years

$PRT = I\\\\P*\frac{7}{100}*5=16100\\\\P=16100*\frac{100}{7*5}$

P= N 46000
