4. I hope this is helpful.
Answer:
The solution is B) (3, 1).
Step-by-step explanation:
For the system of equations given, there are few different ways to solve. Since the second equation y = 2x - 5 is already solved for 'y', we can use substitution and place the expression '2x - 5' in for 'y' in the first equation and solve:
2x - 5 + 2 = x
We can also solve for 'y' in the first equation and then set the two equations equal to each other:
y + 2 - 2 = x -2 or y = x -2 so, 2x -5 = x - 2
Either way, when we solve for 'x', we get:
2x - 3 = x or -3 = -x, so x = 3
Plugging in the value of 'x' into the second equation:
y = 2(3) - 5 or y = 6 - 5 or y = 1
The ordered pair (x, y) would be (3, 1).
The midline of the standard cos function is y=0
the function is translated 5 units up.
so the answer is e: y=5.
1) 2 : 1/2 = 4 (miles/hour)
2) 3 : 4 = 3/4 (hour)
Answer: you will walk 3 miles in 3/4 hour.
Answer:
y = (75x + 500)
Step-by-step explanation:
To find the linear model,
Let y = monthly balance of the savings
x = months of the savings
With savings account with $500 which is fixed
deposits = $75
Then the model is
y = (75x + 500)
