Answer:

y+1=2(x+3)

Step-by-step explanation:

we know that

The equation of a line in point slope form is equal to

y-y1=m(x-x1)

we have

m=2\\(x1,y1)=(-3,-1)

substitute

y+1=2(x+3)

tangare [24]

Answer:

8 years approximately

The problem (I'm assuming is):

Solve 100e^{0.05t}=150.

I put a t in the problem where I suspected it in went.

Step-by-step explanation:

100e^{0.05t}=150

Divide both sides by 100:

e^{0.05t}=\frac{150}{100}

e^{0.05t}=1.5

Rewrite in logarithm form.

\ln(1.5)=0.05t

Divide both sides by 0.05:

\frac{\ln(1.5)}{0.05}=t

Put left hand side into calculator:

8.109 \approx t

t \approx 8.109

So about 8 years if I wrote down the equation correctly.

Answer:

x = -64

Step-by-step explanation:

Step 1: Write out equation

9 - 3/4x = 57

Step 2: Subtract 9 on both sides

-3/4x = 48

Step 3: Multiply both sides by -4/3

x = -64
