Answer:

y = 1x-1

Step-by-step explanation:

the line intercepts with the y axis at -1 so that's your y intercept.

then, if you go to any point on the line, see where the nearest point is. rise up one and go right one. So, 1 over 1 (1/1) which = 1 so that's m. Your slope. Then put it all together. y= 1x - 1

Please help look at the picture
k0ka [10]

Answer:

y = - 5x - 1

Step-by-step explanation:

The first thing to do (always) is pay attention to x =0. That at least gives you a partial answer. y = y' - 1. when you put 0 in for whatever y' is you get 0. What about the other numbers? How did they come about.

We have another clue. Whenever you put in a positive number for x, you get a negative answer for y. That's interesting. So y' has a minus sign associated with it.

y = -ax - 1    Make a>0 so there is only 1 minus sign. x cannot have an even power, because an even power would make everything positive except the -1.  

So we'll start with y= - ax - 1 We'll also make the assumption that a = 1

y = - x - 1 That won't work. a >1 otherwise x = 2 won't give - 11

y = -ax - 1

let x = 2

let y = - 11 Solve for a

y = - ax - 1

- 11 = -a*-2 - 1       add   1  to both sides

-11 + 1 = - a(-2) - 1 + 1

- 10 = -2a             Divide by - 2

- 10/-2 = -2a/-2

a = 5

Answer: y = - 5x - 1

Sandra bought a tube of toothpaste for $1.89, shampoo for $3.19 and a jar of peanuts for $2.29 from the local supermarket. Using
uranmaximum [27]
To find the total cost, you need to add these numbers together

1.89 + 3.19 + 2.29 = 7.37
you get 7.37 as your answer, but you need to round this to the nearest whole number.

rounding 7.37 will make it 7.

the total cost is about $7

What are three powers that have values greater than 500 and less than 550
igomit [66]

Solution:

The three powers whose value is greater than 500 and less than 550 can be find by following procedure.

We will solve this problem by Hit and trial method by finding the squares, cubes, fourth power, Fifth Power,...etc. of different natural numbers.

23²= 529

8³ = 8 × 8 × 8 =512

2^8=512

The three powers are →→→Eighth power of 2, Square of 23, and Cube of 8.
