Substitute the values of x and y into the expression -3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2. match that value to one of the numbers. 1. x=2 y= - = 14 2. x=0 y=2. = 1.665 3. x= -1 y= - = -1 4. x= .5 y= -1/ =  9.17 5. x= 3/4 y= 2/ = -11.25 6. x= square root of 2 y= square root of = 0.44 don't ask if i have apples like the last guy did.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
