Answer: The ordered pair is (2,3)
Step-by-step explanation:
To solve this problem, we can use substitution. With substitution, we substitute the y in each problem with the equations. In this case, x + 1 can substitute the y in y = -x + 5. Here is what the problem looks like now:
x + 1 = -x + 5
The reason we used substitution is because we assume that these linear equations are equal. We must prove it, though. We can use algebra.
Move the variables to one side and the numerical values to another:
x + x = 5 - 1.
Simplify.
2x = 4
Simplify.
x = 2.
Now, we got our x value, we can substitute it into our problem:
y = 2 + 1
y + -2 + 5
2 + 1 = - 2 + 5 = 3
Our x is 2, and our y is 3. The ordered pair that is a solution is (2,3).
Well she can only buy five times a week. So would the inequality be something like 5 is less then or equal to 10. Sorry if I’m wrong
The answer is 4. You do 12 times 1/3. This is because this is important in order to find out the answer. The answer is 4.
Answer:
-3
Step-by-step explanation:
Looking at the graph, f(x)=7 is only true at x=-3 or you can use the equation
f(x)=-x+4 where you plug in 7 for f(x) !!
Hi There!
Answer:
25x² - 4
Step-by-step explanation:
Solve: (5x - 2)²
Step 1: 25x² - 2²
Step 2: 25x² - 4
Hope This Helps :)
