Answer:
13
4
OR
3
1
4
Step-by-step explanation:
first you work out what is in the brackets
that is
1
3
÷
1
6
to give you 2 as you answer
second step rewrite the whole question replacing two in the place of
1
3
÷
1
6
so you will have
3
4
+
2
−
(
−
1
2
)
thirdly open the brackets with the negative sign outside the bracket that is:
−
(
−
1
2
)
so that you get
+
1
2
(or
1
2
, basically)
lastly rewrite the whole question
so you will have
3
4
+
2
+
1
2
, you add all of them ...
3
4
+
8
4
+
2
4
=
13
4
EXTRA
you can keep that solution, or you can change it from improper fraction to a mixed number
if you use long division,
13
÷
4
=
3
with a remainder of
1
over
4
.
doing this by calculator you get 3.25, which is basically
3
25
100
=
3
1
4
2/9 is an irrational number because it is not a real number
If you divide it becomes a repeating decimal which is not rational
57 miles because of they are driving 38 miles per hour that means in 1 hour they drive 38 miles. So if they drove for an hour and a half you take 38 and half of 38( which is 15) and you add them together.
Answer:
The axis of symmetry is x = 6
Step-by-step explanation:
To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.
x + 9 = 0
x = -9
x - 21 = 0
x = 21
Now take the average of these two numbers.
(-9 + 21)/2
12/2
6
We must plugin values:
3(7)-4(0)=21, is CORRECT since 7•3 is 21 and -4•0 is 0
3(11)-4(3)=21 is CORRECT since 3•11=33 and -4•3=-12 so 33-12=21
3(-3)-4(3)=21 is INCORRECT since 3•-3 is -9 and -4•3 is -12, -9-12 is -21
3(-1)-4(-6)=21 is CORRECT since 3•-1 is -3 and -4•-6 is 24 and so 24-3=21
