6x+4y=-6
2x+5y=9
Please help

Step-by-step explanation:

Simplifying

6x + 4y = 6

Solving

6x + 4y = 6

Solving for variable 'x'.

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

Add '-4y' to each side of the equation.

6x + 4y + -4y = 6 + -4y

Combine like terms: 4y + -4y = 0

6x + 0 = 6 + -4y

6x = 6 + -4y

Divide each side by '6'.

x = 1 + -0.6666666667y

Simplifying

x = 1 + -0.6666666667ySimplifying

6x + 4y = 6

Solving

6x + 4y = 6

Solving for variable 'x'.

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

Add '-4y' to each side of the equation.

6x + 4y + -4y = 6 + -4y

Combine like terms: 4y + -4y = 0

6x + 0 = 6 + -4y

6x = 6 + -4y

Divide each side by '6'.

x = 1 + -0.6666666667

Simplifying

x = 1 + -0.6666666667

Simplifying

2x + 5y = 9

Solving

2x + 5y = 9

Solving for variable 'x'.

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

Add '-5y' to each side of the equation.

2x + 5y + -5y = 9 + -5y

Combine like terms: 5y + -5y = 0

2x + 0 = 9 + -5y

2x = 9 + -5y

Divide each side by '2'.

x = 4.5 + -2.5y

Simplifying

x = 4.5 + -2.5y

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
