8. Find the y-intercept for the linear equation: 3x - 5y = 10

y = -2 + 3x/5

Step-by-step explanation:

Subtract 3x 3 x from both sides of the equation. Divide each term by −5 - 5 and simplify. Divide each term in −5y=10−3x - 5 y = 10 - 3 x by −5 - 5 .

-2

Let's solve for y

Step 1: Add -3x to both sides.

Step 2: Divide both sides by -5.

Therefore the y-intercept (the constant) is -2

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
