4/3

Step-by-step explanation:

-3y + 4x = -6

-3y = -6 -4y

slove for Y

y = -6/-3 -4/-3 x

Y = -2 +4/3x

Y = 4/3 x -2

Y = 4/3 x -2

so slope or gradient is coefficient of x

4/3 is gradient.

a

Equation of a straight line= mx+c

where m is the gradient...

-3y + 4x = -6

-3y = -4x - 6

y = -4/-3x - 6/3

Simplifying we get y = 4/3x - 2

Therefore 4/3 is the gradient because according to the equation y = mx+c, your m value (gradient) is 4/3.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
