on your scientific calculator click on MODE then number 5 then number 3 and put those numbers x^2 – 3x = –8

(AFTER WRITING EACH NUMBER CLICK ON = SO YOU CAN PUT THE OTHER NUMBERS. FOR EXAMPLE, WRITE 1 AS A THEN CLICK = AND SO ON)

1 and A (write 1 first then click =)

-3 as B (write -3 then click =)

+8 as C (write 8 then click =)

Which value of y below is the solution to the system shown below. A) y=6 B) y=-1 C) y=-4 D) y=8

Grace [21]

Answer:

Step-by-step explanation:

given the 2 equations

x + 2y = 27 → (1)

2x + 3y = 46 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 27 - 2y ← substitute into (2)

2(27 - 2y) + 3y = 46

54 - 4y + 3y = 46

54 - y = 46 ( subtract 54 from both sides )

- y = - 8 ( multiply both sides by - 1 )

y = 8 → D
