Answer: y+6x = -34

Step-by-step explanation:

y-2= -6(x+6) (Ax+By=C is the goal)

y-2= -6x-36 (-6) x & (-6) 6

y=-6x-34 (Add 2 to both sides)

y+6x = -34 [Add 6x to both sides]

using the Cosine rule in ΔSTU

let t = SU, s = TU and u = ST, then

t² = u² + s² - (2us cos T )

substitute the appropriate values into the formula

t² = 5² + 9² - (2 × 5 × 9 × cos68° )

= 25 + 81 - 90cos68°

= 106 - 33.71 = 72.29

⇒ t = $\sqrt{72.29}$ ≈ 8.5 in → A

7r²+9=1 quadratic equation.

dezoksy [38]

7r²+9=1

the equation is contradictory, just to prove

7r² + 9 = 1

7r² + 9 -1 = 0

7r² + 8 = 0

We write the equation in the form of products of

7 * (r² + 8/7) = 0

the product is equal to 0 when one of the factors is zero

7≠0 ∨ (r² + 8/7) = 0
r² ≠ - 8/7
any number squared is not negative.

We proved that none of the factors is not equal to zero , so the right side of the equation is not equal to the left . The equation is contradictory

What is the equation in slope-intercept from of the line that passes through the points (-4,47) and (2,-16

Harrizon [31]

Answer:

Step-by-step explanation:

SLOPE FORMULA:

y₂-y₁/x₂-x₁=rise/run

SLOPE-INTERCEPT FORM:

y=mx+b

m represents the slope.

b represents the y-intercept.

y₂=(-16)

y₁=47

x₂=2

y₁=(-4)

Solve.

$\displaystyle \mathsf{\frac{(-16)-47}{2-(-4)}=\frac{21}{6}=\frac{21}{2}=-\frac{21}{2} }}$

Furthermore, the y-intercept is 5.

y=-21/2x+5

The correct answer is y=-21/2x+5.
