how do u solve this system equation?

y = 2x - 11

4x + 3y = -13

To solve this system using substitution, substitute (2x - 11) into the second equation for y and solve algebraically for x.

4x + 3y = -13 (given)

4x + 3(2x - 11) = -13 (substitute)

4x + 6x - 33 = -13 (distribute)

10x - 33 = -13 (collect like terms)

10x = 20 (add 33 to both sides)

x = 2 (divide both sides by 10)

Substitute 2 for x into either of the original equations.

y = 2x - 11 (given)

y = 2(2) - 11 (substitute)

y = 4 - 11 (multiply)

y = -7 (subtract)

x = 2 and y = -7; (2, -7).

x= 3^y

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
