Concerning the interrogate, the retort to such is identified as the following,,
Convert the Slope-Intercept Form to General Form:
Y = -2x - 9 ==> 2x + y = -9
Evaluate:
2x + y = -9
2x + 3y = -9
Multiply the X factors by each other, making one of the products opposite:
-2(2x + y) = -9 ==> -4x - 2y = 18
2(2x + 3y) = -9 ==> 4x + 6y = -18
Add the expressions:
-4x - 2y = 18
4x + 6y = -18
————————
4y = 0
Y = 0
Now, substitute the zero within one of the equations:
2x + 3y = -9
2x + 3(0) = -9
2x = -9
X = -4.5
Thus, (-4.5,0)
Answer:
−66/7(Decimal: -9.428571)
C ÷ D- EXPRESSION
-24÷1/4=-18
24
- 6
---------
18
The answer is negative because when you divide 24 by 4 you get 6. and since the number 24 is negative.you need to subtract 6 from 24 to get -18 which is negative.
P.S:I am a 6th graders who doesn't really understand negatives, but i tried my best and got this answer.
