Answer:

<u>y = 1</u>

Step-by-step explanation:

<u>Given</u>

y ∝ x⁴

⇒ y = kx⁴

<u>Finding the proportionality constant, k</u>

y = 16 and x = 3
16 = k (6)⁴
16 = 1296k
k = 16/1296
k = 1/81

<u>Finding y</u>

y = 1/81 x (3)⁴
y = 1/81 x (81)
<u>y = 1</u>

6 / (x + 6) = 10/15

10(x+6) = 90

10x + 60 = 90

10x = 30

x = 3

HELP!!!! I’LL GIVE THE BRIANLIEST TO WHOEVER GETS IT RIGHT!!!!

Answer:

13 units

Step-by-step explanation:

D is at (1,6) and C is at (-4,-6)

The distance is found by

d = sqrt(( y2-y1)^2+ (x2-x1)^2))

= sqrt( ( -6-6)^2 + (-4-1)^2)

= sqrt( -12^2 + -5^2)

= sqrt( 144+ 25)

= sqrt( 169)

= 13

Find the slope of the line passing through the points (-6, 6) and (4. – 7).

postnew [5]

Answer:

$\displaystyle -\frac{13}{10}$

Step-by-step explanation:

To solve this problem, first you have to use the slope formula of $\displaystyle \frac{y_2-y_1}{x_2-x_1}$ .

y2= (-7)

y1=6

x2=4

x1(-6)

Solve.

$\displaystyle \frac{(-7)-6}{4-(-6)}=\frac{-13}{10}=\boxed{-\frac{13}{10}}$

Therefore, the correct answer is -13/10.
