Answer:
The statement is true
Step-by-step explanation:
The question is as following :
is divisible by 7 and 19, true or false?
The given expression is
Take 
as a common
So, 
divided 7 = 
And divided 19 = 
is divisible by 7 and 19 (<u>True</u>)
Okay lets create an eqn from that information
A first int, B second int, C third int, D fourth int.
B = A + 2
C = A + 4
D = A + 6
A is the smallest integer
B + D = 0.5 (A + C)
Now lets substitute
(A + 2) + (A + 6) = 0.5(A + (A + 4))
now lets dist
2a + 8 = 0.5(2a +4)
2a + 8 = a + 2
a + 8 = 2
a = -6
B = -6 +2
B = -4
C = -6 + 4
C = -2
D = -6 + 6
D = 0
Now using B + D = 0.5(A + C)
-4 + 0 = 0.5(-6 + (-2))
-4 = 0.5 (-8)
-4 = -4
Correct
Therefore, First integer is -6, second integer is -4, third integer is -2 and fourth integer is 0
Answer:
Once you know the sum, you can divide that by 12 to get the measure of each interior angle: 1800°/12 = 150°
Step-by-step explanation:
Answer:
4 hours
Step-by-step explanation:
The speed of the first car is
While the speed of the second car is
The time it takes for each car to cover a distance d is
where
d = 960 km is the total distance covered
For car 1, the time taken is:
For car 2, the time taken is:
Therefore, the difference in time is:
To find the vertex, you need to find the axis of symmetry first.
In order to find the axis of symmetry we have to do -b/2a.
In our case, the b is -8 and the a is 1.
Plug it in.
-(-8)/2(1)
8/2 = 4
Our axis of symmetry is 4.
Now, we plug it into the equation to find the rest of the vertex.
y = 4^2 - 8(4) + 1
y = 16 - 32 + 1
y = -16 + 1
y = -15
Put it together.
Our vertex is (4,-15).
