Find y if the line through (3, 1) and (9, y) has a slope of 4.
klio [65]

Answer:

y = 25

Step-by-step explanation:

To find slope, we use this expression: \frac{y2-y1}{x2-x1}

Since we already know the slope and are trying to figure out a y-value, we can input all of the values we do know in the expression and solve for the missing y.

\frac{y-1}{9-3}=4

Simplify the denominator:  \frac{y-1}{6}=4

Multiply both sides by 6 to isolate the y - 1:   y - 1 = 24

Add 1 to both sides to isolate the y:  y = 25

y = 25

Answer:

Step-by-step explanation:

(s/2)^2+h^2=s^2

h^2=s^2-(s^2/4)

h^2=(3s^2)/4

h=(s/2)(3^(1/2)), s=20

h=10(3^(1/2)) simplest radical form 10 times square root of 3

h=17.32 approximate decimal to nearest one hundredth
