Answer:
Constant of proportionality is y divided by x. y is 2 and x is 4. 2 divided by 4 is 1/2.
Let me know if that is correct.
Step-by-step explanation:
Answer:
No Solutions
Step-by-step explanation:
We have to create an equation to be able to solve this problem.
Let's let x = the # of home runs
The equation that helps us solve this is 5 + 1x = 10 + 1x
First, we have to subtract 1x from each side (always subtract the variable first before the constant, math rule)
This brings us to 5=10 because the x's cancel each other out.
You probably look at this saying, wait, this isn't right, and you would be correct
Since this equation isn't true, it is No Solutions
No Solutions mean there is no answer to the problem, it is impossible to solve.
So, our final answer is No Solutions
Hope this helps, have a great day! :)
Answer:
( -4, -3 )
Step-by-step explanation:
Let's solve by elimination. Reason being there are no variables without coefficients.
−5y+3x=3 Multiply equation by 3. Each term.
−8y+9x=−12
-15y + 9x = 9 Subtract the to equations
-8y + 9x = -12
___________
-7y = 21
y = -3
Substitute y into original equation
-5(-3) + 3x = 3
15 + 3x = 3 Subtract 15 both sides
3x = -12 Divide by 3, both sides
x = -4
Answer:
f(-7)=0.
f(2)=-9/5.
f(3) doesn't exist because 3 isn't in the domain of the function.
Step-by-step explanation:
is the given function.
We are asked to find:
.
f(-7) means to replace x in the expression called f with -7:
Evaluate 
at 
So f(-7)=0.
f(2) means to replace x in the expression called f with 2:
Evaluate at 
So f(2)=-9/5
f(3) means to replace x in the expression called f with 3:
Evaluate at 
Division by 0 is not allowed so 3 is not in the domain of our function.
