O When (1, 2) is substituted into the second equation, the equation is true. O When (1, 2) is substituted into the second equation, the equation is false. O When (1, 2) is substituted into the first equation, the equation is false. O When (1, 2) is substituted into the first equation, the equation is true. The ordered pair (1, 2) is not a solution to the system of linear equations 0 The ordered pair (1, 2) is a solution to the system of linear equations.

17 1/3

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

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
