Answer:
so x=5y

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

The answer to that question is $4,750

y=2x-3

y=-2x+5

2x-3 = -2x+5

4x=8

x=2

y=2(2)-3

y=1

the answer is A.(2,1)

y=-2x+5

2x-3 = -2x+5

4x=8

x=2

y=2(2)-3

y=1

the answer is A.(2,1)

g(x) = x^2 – 6x + 14

Hello,

g(x)=x²-6x+14=x²-2*3x+9+14-9=(x-3)²+5

h=3, k=5

g(x)=x²-6x+14=x²-2*3x+9+14-9=(x-3)²+5

h=3, k=5

**Answer: a+6d will defines the series for seven terms i.e. 38.**

**Step-by-step explanation:**

Since we have given that

Here, a = first term = 8

d = common difference is given by

So, we need to find the seven terms:

So, here n = 7

So, it becomes,

**Hence, a+6d will defines the series for seven terms i.e. 38.**

you're just adding 5

example

8+5= 13

13+5=18

18+5=23

23+5=28

28+5=33

and so on :)

example

8+5= 13

13+5=18

18+5=23

23+5=28

28+5=33

and so on :)

50.00 - 30 % = 35

Because ⬇

50.00( 50.00 × 3 ÷ 100)

50.00 - 15.00 = 35.00

That's how I found out that "50.00 - 30% " was equalling to '35' (or you can put '35.00'

Because ⬇

50.00( 50.00 × 3 ÷ 100)

50.00 - 15.00 = 35.00

For point (1, -2): -2 = -1 - 1 = -2. Therefore, point (1, -2) lies on the graph of the equation.

The graph of the equation is the set of points that are solutions to the equation.

A coordinate pair on the graph of the equation is a solution to the equation.

For the point (0, -1): -1 = -(0) - 1 = 0 - 1 = -1.

Therefore, The point ( 0, −1 ) lies on the graph of the equation.
