We are going to rewrite both numbers:
 (4.2 × 10 ^ 6) = 4200000
 (2.25 × 10 ^ 5) = 225000
 Adding we have:
 4200000 + 225000 = 4425000
 Rewriting in exponential notation we have:
 4425000 = 4,425 * 10 ^ 6
 Answer:
 
(4.2 × 10 ^ 6) + (2.25 × 10 ^ 5) is equal to:
 
4,425 * 10 ^ 6

A pakage of 5 pairs of inclated gloves cost $29.45 what is the unit costof the pairs of gloves
castortr0y [4]
I'm not entirely sure of your question, but I'll try to answer haha. If you're asking what the unit would be for a pair of gloves, it would still be in dollars. If you're asking how much one pair of gloves costs, you would divide the total number (29.45) by the number of items you have (5 pairs). Your answer is $5.89 for a pair of gloves. Hope this helps, but sorry if it doesn't!

Solve: x^2 - 7x = -13
Reika [66]
There are a various of ways solve this expression. We can choose to do completing the square method or to use the quadratic formula. In this case, I will choose to do completing the square. We do as follows:

<span>x^2 - 7x = -13
</span><span>x^2 - 7x + 49/2= -13 + 49/2
(x - 7/2)^2= 23/2
</span>√[(x - 7/2)^2]= √(23/2)
x-7/2 = √46 / 2
x = √46 / 2 + 7/2

Hope this answers the question. Have a nice day.

If y = 6x - 4 which of the following sets represents possible inputs and outputs of the function represented as ordered pairs?
noname [10]

The only of these that is a proper set of ordered pairs for this equations is A) (0,-4) (1,2) (3,14)

In order to prove this, you need to put each ordered pair into the equation and prove that it is a true statement. Below are the examples of this for A.

(0, -4)

y = 6x - 4

-4 = 6(0) - 4

-4 = 0 - 4

-4 = -4 (TRUE)

(1, 2)

y = 6x - 4

2 = 6(1) - 4

2 = 6 - 4

2 = 2 (TRUE)

(3, 14)

y = 6x - 4

14 = 6(3) - 4

14 = 18 - 4

14 = 14 (TRUE)

Therefore, each of these ordered pairs works in the equation.
