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:
first one the rate is 4
the starting value is 3
and the equation is
y=3x+4
Step-by-step explanation:
Answer:
35i+13j
Step-by-step explanation:
Vector a = 9i+9j
Vector b = -4i+7j
We need to find the value of 3a-2b.
3a = 3(9i+9j) = 27i+27j
2b = 2(-4i+7j) = -8i+14j
3a-2b = 27i+27j-(-8i+14j)
= 27i+27j+8i-14j
= 35i+13j
Hence, the required vector is equal to 35i+13j.
Answer:
It helps you see the visual move of what you were doing. If you weren't moving anything it would help you see if it is true or false. Say you put a dot on the origin (0,0), then you have to go (x+7,y+3) then moving it on a graph would help show you. So overall it's a visual help to people.
44 mm = 6 m on blue print.
1 mm = (6/44) m
33 mm = (6/44) * 33 = 4.5 m
The actual length = 4.5 meters.
