Answer:

The graph is attached below

Step-by-step explanation:

Graph the line for $y+1=-35(x-4)$

Solve the equation for y to graph the given equation of the line

$y+1=-35(x-4)$

$y+1=-35x+140$

Subtract 1 from both sides

$y=-35x+139$

Make a table to graph the equation, Assume some random number for x and find out y

x $y=-35x+139$

Mrs. Martini is 6 years more than 3 times as old as Tony. Eight years ago, she

zalisa [80]

Mrs Martini age is 42 years and Tony age is 12 years

Step-by-step explanation:

The given is:

Mrs. Martini is 6 years more than 3 times as old as Tony
Eight years ago, she was 2 years less than 9 times as old as he was then

Assume that Tony is x years old now

∵ Mrs. Martini is 6 years more than 3 times as old as Tony

∵ Tony is x years old

- Multiply the age of Tony by 3 and add 6 to the product

∴ The age of Mrs Martini = 3 x + 6

8 years ago

- Subtract 8 from the age of each one

Tony age = (x - 8)

Mrs Martini age = (3 x + 6) - 8 = 3 x + 6 - 8 = 3 x - 2

∵ Eight years ago, Mrs Martini was 2 years less than 9 times as old

as Tony was then

- Multiply Tony age by 9 and subtract 2 from the product

∵ Tony age from 8 years ago = x - 8

∵ Mrs Martini age from 8 years ago = 3 x - 2

∴ 9(x - 8) - 2 = 3 x - 2

- Simplify the left hand side

∴ 9 x - 72 - 2 = 3 x - 2

- Add like terms

∴ 9 x - 74 = 3 x - 2

- Subtract 3 x from both sides

∴ 6 x - 74 = -2

- Add 74 to both sides

∴ 6 x = 72

- Divide both sides by 6

∴ x = 12

∵ x represents the age of Tony

∴ Tony is 12 years old

∴ 3 x + 6 is the age of Mrs Martini

- Substitute x by 12

∵ 3(12) + 6 = 36 + 6 = 42

∴ Mrs Martini is 42 years old

Mrs Martini age is 42 years and Tony age is 12 years

He solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?

Nimfa-mama [501]

Answer:

$-0.8=-0.8$

Step-by-step explanation:

We have been given that n=-2 verified as a solution to the equation $1.4n+2=2n+3.2$ .

As n=-2 is the solution for our given equation, so it will satisfy our equation.

Let us substitute n=-2 is our given equation.

$1.4*-2+2=2*-2+3.2$

$-2.8+2=-4+3.2$

$-0.8=-0.8$

Since the value of n satisfies our equation, therefore, last line of the justification will be $-0.8=-0.8$ .

For what value of k does the graph of y = x²-3x-k pass through the point (-1,2)?

gavmur [86]

The value of k should be 2.
if you plug the y value of the point in the equation for y and do the same with x you should be able to get this answer after fallowing the order of operation.
