Answer:
5.49
Step-by-step explanation:
5.48<u>9,</u> the number 9 that is underlined is 5 or more so you put that at 0 then it would be 5.48, but since the 8 is also 5 or more and is the hundreths place you round that to 9 giving you 5.49
Answer:
-12
Step-by-step explanation:
Step1: Add 3 to both sides of the equation
2x -3 = 5x +6
+3 +3 = 9
Step2: subtract 5x from both sides of the equation
2x = 5x +9
-5 -5
Step3: divide both sides of the equation by the same term
-3x(/ -3) = 9(/-3)
<h3>X=-3</h3>
Step4: multiply -3 with 2
-3x2= -6
Step4: subtract -6 with 3
-6 - 3= -9
<h3>
Y=-9</h3>
Step5: add the -9 to -3
-9 + -3 = -12
ANSWER: -12
<h3>
</h3>
Replace X in the equation with 0:
f(0) = 3-2(0)
f(0) = 3-0
f(0) = 3
