Answer:

Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4. A number that can only be factored as 1 times itself is called "prime". The first few primes are 2, 3, 5, 7, 11, and 13.

When the exponent blank is applied to a nonzero base, the result is always 1

boyakko [2]

Answer:

zero (0)

when the exponent 0 is applied to a nonzero base, the result is always 1

Step-by-step explanation:

Acoording to the zero power rule, a non zero number raised to the power 0 is always 1:

$a^{0} =1$ whit $a=0$

Let's check this property using an example:

We know that a quantity over itself is always 1: $\frac{2}{2} =1$

We also know that a base without exponent is always raised to the power 1: $2=2^{1}$

Now, according to the division power rule $\frac{a^{m} }{a^{n}} =a^{m-n}$ , so $\frac{2}{2} =\frac{2^{1} }{2^{1} } =2^{1-1} =2^{0} =1$

you have been given an engine repair job that has a job time of 7 hours how many minutes should you allow for your job?

Soloha48 [4]

Answer:

$Job\ Time = 420\ minutes$

Step-by-step explanation:

Given

$Job\ Time = 7\ hours$

Required

Determine the job time in minutes

To do this, we simply convert the time to minutes.

$1\ hour = 60\ minutes$

$7\ hours = 7 * 60\ minutes$

So, we have:

$Job\ Time = 7 * 60\ minutes$

$Job\ Time = 420\ minutes$

<em>Hence, the job time in minutes is 420 minutes</em>

Tell which equation you use to solve for one of the variables when solving the system by substitution: 2x + 3y = 5 or 4x - y =3

mixas84 [53]

You can using any equation you want to solve for one of the variables. For instance, if you want to solve for x you turn one of the equations so y is by its self
<span>
2x + 3y = 5
4x - y =3

I am going to use </span>4x - y =3
-y = -4x + 3
y = 4x -3
Now you can substitute 4x - 3 for y in 2x + 3y = 5 and solve for x
2x + 3y = 5
2x + 3(4x - 3) = 5
