13 = 1/6y +2x plz help

Answers

Answer:

in standard form - y+12x=78

in slope intercept form - y=-12x+78

Step-by-step explanation:

standard form

13=1/6y+2x

multiply both sides by 6

78=y+12x

y+12x=78

slope intercept

13=1/6y+2x

subtract 1/6y from both sides

13-1/6y=2x

subtract 13 from both sides

-1/6y=2x-13

change the signs on both sides of the equation

1/6y=-2x+13

divide both sides by 1/6

y=-12x+78

Step-by-step explanation:

Answer:

Hint(look at the first number in each part and math it with the first number in each answer.) For example, 3(937), the distributive property for that one would be 3(900) + 3(30) + 3(7). Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.

16x=112
X=7


3) These angles are equal too
7x-1=125
7x=126

4) These angles are supplementary so they add to 180 degrees
9x+2+133=180
9x+135=180
9x=45

X=23


6) These angles are also equal
11x-47=6x-2
5x-47=-2
5x=45
X=9


7) these also sum to 180
13x-21+5x+75=180
18x+54=180
18x=126
X=7


8) These angles add to 180 as well
9x-33+5x+3=180

3. Consider the iterative rules you wrote in Problem 2. (a) Explain why the rules are functions. (b) Your friend says that because the rules are functions, they can be graphed and must have y-intercepts. How would you respond to your friend’s comment? (c) Your friend uses your rules to determine the outputs when the inputs are 18.5. Explain why her outputs are meaningless in this situation. What would you tell her about the inputs she can use? Answer:

Answers

The inputs which are required mention below in descriptive.

What is Function?

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math.

(a) The rules are functions because each input has only one output. You can test this out, it's true.

(b) So we did have to find the "y-intercept" earlier. But you have to look at the domain. There won't be any amount paid on Week 0, payment starts at Week 1. So you would have to respond that yes, they can be graphed, but there's no y-intercept; the graph starts at week 1. Additionally, there are only data points at the integer values of x. Look at part c.

(c) The outputs are meaningless because you're counting the time by weeks. There won't be any amount paid in the middle of the week, so she can only use integer inputs.

Answers

Answer:

z = 36

Step-by-step explanation:

1) Distribute

2) Combine like terms

-18 = -z + 18

3) Subtract 18 from both sides of the equation

-18 - 18 = -z + 18 - 18

4) Simplify

a. Subtract the numbers

-36 = -z + 18 - 18

b. Subtract the numbers

-36 = z

5) Divide both sides of the equation by the same term
