Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is <em>not</em> 42 - it's 41. So, Sarah is incorrect.
|2x + y - 3z|
Plug in the values
|-4 + 10 - 9|
= |-3|
= 3
12x3+27x2+23x+10/ 4x+5
3x2 + 3x + 2
Answer:
Tyler didn't make a mistake
Step-by-step explanation:
3(x+4)=-18
(x+4)=-18/3 (divide by 3 on both the sides)
x+4=-6
x=-6-4 (subtract 4 from both the sides)
x=-10
