Answer:

We have ordered pairs (60,360), (120,720), (180,1080), (240,1440), and (300,1800) as the answer.

Step-by-step explanation:

The table would look like this:

Under minutes you would place 60, 120, 180, 240, and 300.

Under calories you would place 360, 720, 1080, 1440, and 1800.

y = 6x

Multiply 60, 120, 180, 240, and 300 by 6 for 6 calories.  This gives us the ordered pairs above.

What is the next step for x2-6x+9=-1+9
Ede4ka [16]
X^2 - 6x + 9 = -1 + 9. We need to solve for x.
First, add one on each side of the equation:
x^2 - 6x + 9 + 1 = -1 + 9 + 1
x^2 - 6x + 10 = 9
Then subtract 9 from each side:
x^2 - 6x + 10 - 9 = 9-9
x^2 - 6x + 1 = 0
Now we got an equation = 0. This an equation from the second degree, it represented by a parabola which turns up since a>0.
This equation is the developed form as ax^2 + bx + c with a=1; b = -6; and c=1.
Now, to find the zeroes of this equation, we need to find delta Δ.
Δ = b^2 - 4ac.
If Δ>0, the equation admits 2 zeroes: x=(-b-√Δ)/2a and x = (-b+√Δ)/2a.
If Δ<0, the equation doesn't admits any zero.
If Δ=0, the equation admits one zero x = -b/2a

Δ = (-6)^2 - 4(1)(1)
Δ = 36 - 4
Δ = 32
Δ>0
So the zeroes of the equation are:
x = (-b-√Δ)/2a = (6-4√2)/2
x = (-b+√Δ)/2a = (6+4√2)/2

Hope this Helps! :)

Express 4 250 000 000 000 in standard form
AlladinOne [14]

hi <3

standard form is written in the form a x 10^n

where a is a number between 1 and 10

in this case, you would get 4.25 x 10^12

BARSIC [14]

Answer:

a.false

b.true

c.false

d.I really can't get about it.

e.false

Step-by-step explanation:

So,here;

a.9.9.3=35 is given

or,243=35 (which is false)

b.7+7+7=3+3+3+3+3+3+3

or,21=21 (which is true)

c.2/3/2=2/3

or,2*2/3=2/3

or,4/3=2/3(which is false)

e.6+6+6=63

or,18=63 (which is false)
