Answer:
a. or
Step-by-step explanation:
Slope is equal to y1-y2 over x1-x2.
So the equation would be:
2-(-1)=2+1=3
-3-(-1)=-3+1=-2
So the answer is:
Answer:
<em>* Substation :</em>
Subtract y from both sides of the equation.
x=6−y
x−y=4
Replace all occurrences of x with 6−y in each equation.
6−2y=4
x=6−y
Solve for y in the first equation.
y=1
x=6−y
Replace all occurrences of y with 1 in each equation.
x=5
y=1
The solution to the system is the complete set of ordered pairs that are valid solutions. (5,1)
The result can be shown in multiple forms. Point Form: (5,1)
Equation Form: x=5,y=1
<em>* Elimination :</em>
Multiply each equation by the value that makes the coefficients of x opposite.
x+y=6
(−1)⋅(x−y)=(−1)(4)
Simplify.
x+y=6
−x+y=−4
Add the two equations together to eliminate x from the system.
(x+y=6) + (−x+y=−4) = (2y=2)
Divide each term by 2 and simplify.
y=1
Substitute the value found for y into one of the original equations, then solve for x.
x=5
The solution to the independent system of equations can be represented as a point.
(5,1)
The result can be shown in multiple forms. Point Form:(5,1)
Equation Form: x=5,y=1
Step-by-step explanation:
<em>* Graph</em>
3 years is 36 months
36 * 199.29 =7174.44
this is the amount he pays in 3 years
payment - principal = interest
174.44-6000=1174.44
this is the amount of interest
Choice B
Answer:
The Answer would be B. 320
Step-by-step explanation:
2. Tom's brother saw Muscle Fitness, which offers $20 off of the $80 fee. Membership is $15 a month plus another $5 a month.
First, solve the one time fee
$80 - 20 = $60
Next, solve the monthly fee
15 + 5 = 20
(a) The expression: Let x = month
20x + 60
(b) Remember the previous question.
<em>Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month. </em>
<em>(a) Write a expression to represent the membership cost of Platinum Gym for x months.</em>
<em>Let x = months</em>
<em>20x + 60</em><em> is your expression</em>
No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.
