Find the value of y so that the line passing through the points (2,5) and (7,y) has a slope of 2/3

1 answer:

5 0

Well we know Slope Intercept Form is change in y over change in x. So y-5/7-2. So we need a slope of 2/3 we have y-5/5. So know we need to make both fractions equivalent so 2/3=10/15 and y-5/5=y-5/15. Now we know that y-5 has to equal 10 so what subtracted by 5 is 10 yup 15.

Answer: y=15

15-5/15
10/15

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
