Answer:

$\displaystyle y = -\frac{1}{4}x - 10$

Step-by-step explanation:

Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 4 becomes −¼. Now, proceed with plugging the information into the Slope-Intercept Formula:

$\displaystyle -11 = -\frac{1}{4}[4] + b \hookrightarrow -11 = -1 + b; -10 = b \\ \\ \boxed{y = -\frac{1}{4}x - 10}$

I am joyous to assist you at any time.

4.solve for x and y pls help

DaniilM [7]

Answer:

x = 4 $\sqrt{3}$

y = 8 $\sqrt{3}$

Step-by-step explanation:

this is a 30-60-90 triangle and the sides have a constant ratio

the side across from the 30°∡ is 1

the side across from the 60°∡ is √3

the side across from the 90°∡ is 2

In this problem we can find 'x' by setting up this proportion:

x/12 = $\sqrt{3}$ /1

cross-multiply:

$\sqrt{3}$ x = 12

x = 12/ $\sqrt{3}$

since we don't like to leave radicals in the denominator, we can multiply both numerator and denominator by $\sqrt{3}$ to get:

12 $\sqrt{3}$ ÷ $\sqrt{3}$ · $\sqrt{3}$ ( $\sqrt{3}$ · $\sqrt{3}$ = $\sqrt{9}$ , which equals 3)

so we have 12 $\sqrt{3}$ /3, which is 4 $\sqrt{3}$

The 'y' value will be twice the 30° side, so 8 $\sqrt{3}$

Answer:interesting question

Step-by-step explanation:

well actually the FOIL method came from And is the distbutive property. So I think you are fine if you use foil as you “distributing” iyk what i mean.

remember Foil is only used in multiplying binomials like your example.
