Answer:
the answer is -4
Step-by-step explanation:
step 1: -7m<28
step 2: -7m÷ (-7)>28÷(-7)
step 3: m>28÷(-7)
step 4: m>-28÷7
step 5: m>-4
Answer:
$97.15.
Step-by-step explanation:
We have been given that a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month. The interest rate of credit card is 3.35% monthly.
We will use interest formula to solve our given problem.
, where,
,
,
,
Let us convert our given interest rate in decimal form.

Upon substituting our given values in interest formula we will get,



Therefore, the monthly interest charge at the end of the 1st month will be $97.15.
3x+4y=12
4y=12-3x
y=(12-3x)/4 <---------- This is f(x)
---------------------
3x+4y=12
3x=12-4y
x=(12-4y)/3
Therefore:
f⁻¹(x)=(12-4x)/3
=[4(3-x)]/3
Answer :
Step-by-step explanation:
A linear inequality in two variables is given to us and we need to plot it's graph .So the the given inequality is ,
So firstly let's simplify out the inequality for easy plotting of the graph .
Now let's put some values of x to get values of y .
• Firstly put x = 0 then we get , y is greater than or equal to 0+5/5 (-1) = 5/5(-1) = -1 . Hence we get y ≥ (-1) .
• Secondly put x = 1 , then we get , y is greater than or equal to 1+5/5(-1)=6/5(-1) = -6/5 . Hence we get y ≥ -6/5 .
• Thirdly put x = -1 , then we get y is greater than or equal to -1+5/5(-1) = -4/5 . Hence we get y ≥ -4/5
• Fourthly put x = (-5) , then we get y is greater than or equal to -5+5/5(-1) = 0 .Hence we get y ≥ 0 .
With reference to these let's plot a graph . For the graph kindly refer to the attachment :) .
Here in the graph the red area shows the possible values of x and y .
