Answer:

y =-2x+7

Step-by-step explanation:

Hello : let A(2,3) B(1,5)

the slope is : (YB - YA)/(XB -XA)

(5-3)/(1-2) = 2/-1 =-2

an equation is : y=ax+b a is a slope

y = -2x +b

the line through point (2,3) : 3 = (-2)(2)+b

b = 7

the equation is : y =-2x+7

3.920 * (1.018)^x = 5.500<br><br>X=?

Andrei [34K]

Answer:

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
Then we can divide both sides by ln(1.108) to get: $x=\frac{ln(1.403)}{ln(1.018)}$
Then using a calculator we get x = 18.98 ≈19
