13.32 = 3/5
1/5 = 13.32 / 3
1/5 = 4.44
Full cost = 4.44 * 5
= 22.20
Solve for x in first equation:
x-2y=7
Add “2y” to both sides
x=2y+7
Put this in to second equation:
3(2y+7)+2y=21
Solve for y:
Distribute the 3 into the ()
6y+21+2y=21
Combine the like y terms
8y+21=21
Subtract 21 from both sides
8y=0
Divide by 8 on both sides
y=0
Put this into the first solved equation:
x=2(0)+7
Solve for x:
Multiple 2(0)
x=0+7
Add 0 and 7
x=7
So the value of x is positive 7.
the function f has a domain of {1,3,5,7} and a range of {2,4,6}. could f be represented by {(1,2),(3,4),(5,6),(7,2)}? justify yo
maria [59]
Yes, f could be represented by this relation. This is because for a relation to be a function, every x value should have one and only one y value; when you plot the points, the graph must pass the vertical line test, which states that for a graph to be a function, a vertical line can only pass through the graph once in any part of the graph.
Hope this helps!
Answer:
The equation to represent g(x) will be 
Step-by-step explanation:
Considering the logarithmic function
As we know that when a constant c gets added to the parent function, the result would be a vertical shift c units in the direction of the sign of c.
So,
is basically the shift up by 4 units, and the graph also showing the same situation.
Therefore, the equation to represent g(x) will be
Also, the graphs of both and is attached where black mark graph represents and red mark graph represents .

Answer:
(0, 2) and (- 1, 4)
Step-by-step explanation:
The solutions to the system of equations are at the points of intersection of f(x) and g(x)
These are at (0, 2) and (- 1, 4)
