Put the following equation of a line into slope-intercept form, simplifying all
fractions
2x - y = 2
Answers
Explanation: The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Subtract 2x from both sides of the equation.
-y = 2 - 2x
Multiply each term in -y = 2 - 2x by -1
(-y) . -1 = 2 . -1 + (-2x) . -1
Multiply (-y) . -1
Multiply -1 by -1
Multiply y by 1
y = 2 . -1 + (-2x) . -1
Simplify each term
Multiply 2 by -1
y = -2 + (-2x) . -1
Multiply -1 by -2
y = -2 + 2x
Reorder -2 and 2x
y = 2x - 2

The answer is
(Simplify your answer.)
Answers
Answer:
-0.002
3x+5=6x-8
Answer:
x=1.4
Step-by-step explanation:
6x-8 -3x+5
+3x +3x
So now we have: 9x-8 5 so add 8 on both sides, leaving you with 9x on one and 13 on the other. Now divide 13 by 9, which is 1.4_ so x=1.4
Now do 3 times 1.4 plus 5 and 6 times 1.4 minus 8 and the results you get for each you will need to subtract: (result of 6x-8) - (result of 3x + 5)

Determine whether the function shown in the graph is even or odd.
The graph starts at the bottom left, continues up through the x-axis near negative one point seven five to a maximum around y equals two, goes back down through the x-axis at the origin to a minimum around y equals negative two, and goes back up through the x-axis near one point seven five.
A) The function is even because it is symmetric with respect to the y-axis
B) The function is odd because it is symmetric with respect to the y-axis.
C) The function is even because it is symmetric with respect to the origin.
D) The function is odd because it is symmetric with respect to the origin.

Darren is training for a triathlon. Each week, he goes to the gym for a maximum of 20 hours. He spends at least 8 of those hours weightlifting (x). He wants to spend no more than 15 hours doing cardio exercises (y). Write a system of linear inequalities that represents the restrictions of this scenario.
Answers
Answer:
y ≤ 20-8x
Step-by-step explanation:
Darren needs to spend no more than 15 hours on cardio exercise (y). To figure out how much time he has we need to do 20-8x. Any leftover hours are the hours left for him to spend doing his exercises. Since y has to be less than or equal to 20-8x, the system of linear inequalities should be:
y ≤ 20-8x

You have $75 in your bank account. Each week you plan to deposit $8 from your allowance and $25 from your paycheck. The equation b=75+(25+8)w gives the amount b in your account after w weeks. How many weeks from now will you have $270 in your bank account?
Answers
Answer:
Step-by-step explanation:
Combine the two sources of income (25 + 8) = 33
b = 75+ (33)w
Let b = 270
Solve for w
270 = 75 + 33*w Subtract 75 from both sides
270 - 75 = 33w
195 = 33w Divide by 33
195/33 = w
w = 5.91 weeks
The question is what do you do now?
The answer should be that you round to the next week which means that it will take you 6 weeks to get just over 270 dollars.

Then add across
67/12 (improper fraction)
in mixed number form: 5 7/12
Answer:
67/12 (just in case if they would ask you for the simplified form the answer in is 5 7/12)Step-by-step explanation:
convert both mixed fractions to improper fractions first
2 1/3 = 7/3 3 1/4 = 13/4
(cross multiplication method, to make both fractions have the same denominator)
7/3 + 13/4
7/3 × 4/4 = 28/12
13/4 × 3/3 = 39/12
28/12 + 39/12 = 67/12 (just add, denominator will remain the same)
67/12 (simplify)
67/12 = 5 7/12 (simplified)

The vertex is the coordinates of the turning point of the parabola
The axis of symmetry is a vertical line passing through the vertex with equation
x = c ( where c is the x- coordinate of the vertex )
vertex = (0, 0 ) , axis of symmetry is x = 0 ( the y- axis )
(1)
vertex = (- 2, 4 ) , axis of symmetry is x = - 2
(2)
vertex = (7, 1 ) , axis of symmetry is x = 7
