Answer:
1). Simplifying
-4x + y = 6

Solving
-4x + y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.
-4x + y + -1y = 6 + -1y

Combine like terms: y + -1y = 0
-4x + 0 = 6 + -1y
-4x = 6 + -1y

Divide each side by '-4'.
x = -1.5 + 0.25y

Simplifying
x = -1.5 + 0.25y

2). Simplifying
-5x + -1y = 21

Solving
-5x + -1y = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'y' to each side of the equation.
-5x + -1y + y = 21 + y

Combine like terms: -1y + y = 0
-5x + 0 = 21 + y
-5x = 21 + y

Divide each side by '-5'.
x = -4.2 + -0.2y

Simplifying
x = -4.2 + -0.2y

denpristay [2]

Step-by-step explanation:

p = 0.1, q = 0.9, n = 7

a) Use complementary probability.

P(at least 1) = 1 − P(0)

P(at least 1) = 1 − (0.9)⁷

P(at least 1) = 0.522

b) Use binomial probability.

P = nCr pʳ qⁿ⁻ʳ

P(3) = ₇C₃ (0.1)³ (0.9)⁴

P(3) = 0.023

erica [24]
Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2\pir=x
r=\frac{x}{2 \pi }
Area=\pir^2
so..
A=\pi(\frac{x}{2 \pi })^2
=\pi(\frac{x^{2} }{4 \pi ^{2} })
=\frac{x^{2} }{4 \pi }

(38-x) is perimeter
then 
\frac{38-x}{4}
(\frac{38-x}{4})^2
\frac{x^{2} }{4 \pi } + (\frac{38-x}{4})^2
then you graph it and it equals
16.716 cm the circumference of the circle
