Answer: 2a - 7
<u>Step-by-step explanation:</u>
Ana: a
Mrs Vargas: 4a - 4
Leo: 2a + 3
Mrs Vargas - Leo
= (4a - 4) - (2a + 3)
= 4a - 4 -2a - 3
= 2a - 7
Answer:
9m ×5m
Step-by-step explanation:
Area of a rectangle= length ×width
Let the width be W meters and the length be L meters.
2 equations can be written from the given information:
45= WL -----(1)
L= W +4 -----(2)
Substitute (2) into (1):
45= W(W +4)
<em>Expand:</em>
45= W² +4W
<em>-45 on both sides:</em>
W² +4W -45= 0
<em>Factorise:</em>
(W +9)(W -5)= 0
W+9=0 or W-5=0
W= -9 or W= 5
(reject)
Substitute W= 5 into (2):
L= 5 +4
L= 9
∴ The dimensions of the garden is 9m ×5m.
Answer:
m = 300w OR w = m/300
Step-by-step explanation:
They start with 10k, but that's immediately sold, so they're back at a flat 0. Every week they gain 1000 but lose 700 for a net profit of positive 300.
Therefore, the maximum capacity would be 300 multiplied by the number of weeks. If we know the maximum, then the answer would be m (maximum) divided by 300.
Answer: The answer is the second graph, attached herewith.
Step-by-step explanation: The given greatest integer function is
![g(x)=[x+3].](https://tex.z-dn.net/?f=g%28x%29%3D%5Bx%2B3%5D.)
We are to select the correct graph of the above function from the given four optional graphs.
We have
etc.
These points are satisfied by the second graph only, so this will be the correct one.
Thus, the second graph is the correct option and its image is attached.
