Answer:

y = - $\frac{5}{6}$ x + 9

Step-by-step explanation:

0.5x + 0.6y = 5.4

0.6y = -0.5x + 5.4

Multiply 10 on all sides.

6y = -5x + 54

Divide 6 on all sides.

y = - $\frac{5}{6}$ x + 9

Bingel [31]

Hello!

Answer:

$\boxed{2}$

Step-by-step explanation:

$Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{1-(-5)}{4-1}=\frac{6}{3}=2$

Therefore, the slope is 2, which is our final answer.

Hope this helps!

How do you solve this as a solution 9(2 + 3x) < 72

laila [671]

Answer:

x <2

Step-by-step explanation:

9(2 + 3x) < 72

Divide each side by 9

9/9 *(2 + 3x) < 72/9

2+3x < 8

Subtract 2 from each side

2+3x-2 < 8-2

3x<6

Divide each side by 3

3x/3 <6/3

x <2

Give an exponential formula for the number of hiv infections, upper h, (in millions) as a function of years, t, since 1985. Use

ollegr [7]

we can sue formula

$P(t)=P_0e^{kt}$

where

P(t) is population after t years

P0 is initial population

k is growth rate

t is time in years since 1985

Let's assume

h(t)=P(t) is million

h_0=P_0 in million

we can replace it

and we get

$h(t)=h_0e^{kt}$ ..............Answer
