Sine he runs <u>2</u> miles on Monday, we already have a +2.
Then, he runs by a constant rate of 1, which is the constant rate of change per day.
Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2
However, he needs to run at least 6 miles. <u>At least</u> means greater than or equal to. The values for y can be greater than 6, or equal to 6.
y ≥ 6
y = x + 2
Now substitute x + 2 for y.
x + 2 ≥ 6
Subtract 2.
x ≥ 4
This is the inequality. He has to run for at least 4 days.
a) 3x + 5y = 26
b) 2x + 2y = 12
First, we need to find a way to equate either the x terms or the y terms in each equation. a) 6x + 10y = 52
b) 6x + 6y = 36
Then take equation b) from the equation a) to eliminate the x component.
a) 6x + 10y = 52
- b) 6x + 6y = 36
0x + 4y = 16
y = 4 ?
Then substitute the value of y into either equation to find the value of x.
b) 2x + 2y = 12
2x + (2x4) =12
2x + 8 = 12
2x = 4
x = 2
I hope this new information i read helps you maybe understand it and as an example!
0.25, 0.50, 0.74. It could be any of these numbers or any number between these numbers.
Answer:
1 and 3
Explanation:
We are given that:
f(x) = 2ˣ - 2
g(x) = 3x - 3
We want to get the solution of f(x) = g(x). This means that we want to get the values of x that make the two solutions equal
Since the choices givens all belong to the given table, we can simply get the solution by examining the table and comparing f(x) with g(x) at each value:
At x = -1:
f(x) = -3/2
g(x) = -6
f(-1) is not equal to g(-1)
Therefore, this is not a solution
At x = 0:
f(x) = -1
g(x) = -3
f(0) is not equal to g(0)
Therefore, this is not a solution
At x = 1:
f(x) = 0
g(x) = 0
f(1) is equal to g(1)
Therefore, this is a solution
At x = 2:
f(x) = 2
g(x) = 3
f(2) is not equal to g(2)
Therefore, this is not a solution
At x = 3:
f(x) = 6
g(x) = 6
f(3) is not equal to g(3)
Therefore, this is a solution
At x = 4:
f(x) = 14
g(x) = 9
f(4) is not equal to g(4)
Therefore, this is not a solution
At x = 5:
f(x) = 30
g(x) = 12
f(5) is not equal to g(5)
Therefore, this is not a solution
Based on the above, the only solutions among the given choices are 1 and 3
Hope this helps :)
