Answer:

The product equality property allows an equation in one variable to be written as a system of equations

Step-by-step explanation:

We can express an equation in one variable as follows;

f(x) = g(x)

The properties of equality of products allows us to write an equation in one variable into a system of equations as follows;

(x - 3)×(x + 2) = 0

The zero product property gives;

x- 3 = 0 or x + 2 = 0

Also we have;

Product of two negatives = positive

Therefore when (x - 2)² = 25

x - 2 = ±5.

At the school carnival, students are asked to guess the number of marbles in a jar to win a prize. There are 240 marbles in the
Lapatulllka [165]

There is 17% error in the guess.

Step-by-step explanation:

Given,

Number of marbles in jar = Exact value = 240

Closest guess = Approx Value = 280

Percent error = \frac{|approx-exact}{exact}*100

Percent error = \frac{|280-240|}{240}*100\\

Percent error = \frac{|40|}{240}*100

Percent error = \frac{4000}{240}=16.67\%

Rounding off to nearest whole percent

Percent error = 17%

There is 17% error in the guess.

Simplify completely. Leave your answer in exponential form:
stich3 [128]

Answer:

{2}^{3}  \times  {4}^{3}  \times 9

Step-by-step explanation:

Using the division rule when dealing with exponents

\frac{b {}^{h} }{b {}^{j} }  = b {}^{h - j}

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.

so using that we are going to do 2, 4 and 9

\frac{2 {}^{8} }{ {2}^{5} }  =  {2}^{8 - 5 = 3 \:  \:  \:  \:  \: 2 {}^{3} }

\frac{ {4}^{4} }{ {4}^{1} }  =  {4}^{4 - 1}  \:  \:  \:  {4}^{3}

\frac{9 {}^{9} }{ {9}^{8} }  =  {9}^{9 - 8}  = 9 {}^{1}

Combine all the terms and we get

{2}^{3} \times 4 {}^{3}  \times  {9}

Yuliya22 [10]
The answer is $122.13

Explanation:

610 • 0.32 = 1,105.6

Then you’re going to add everything up:

650 + 260.40 + 260.40 + 16.95 + 11.56 + 10.56 + 17.84

And get =

1,227.73

And you’re going to subtract that with 1,105.6 and get the answer.
