Answer:

division.

Step-by-step explanation:

this property states that when you divide both sides of an equation by the same number, the two sides remain equal.

so in your equation, when you divide by 6, you know that y = 8.

The property that justifies the statement is the Division Property of Equality because we divided both sides by a constant value.

Equations are expressions separated by an equal sign.

Given the expression 6y = 48

To get the value of y, we will have to divide both sides by 6 as shown:

6y = 48 (Division Property of Equality)

6y/6 = 48/6

y = 8

Hence the property that justifies the statement is the Division Property of Equality because we divided both sides by a constant value.

Determine the next step for solving the quadratic equation by completing the square. 0 = –2x2 + 2x + 3 –3 = –2x2 + 2x –3 = –2(x2

VLD [36.1K]

We have that
0 = –2x²+ 2x + 3

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(–2x²+ 2x)=-3

Factor the leading coefficient

-2*(x²-x)=-3

Complete the square. Remember to balance the equation by adding the same constants to each side

-2*(x²-x+0.25)=-3-0.50

Rewrite as perfect squares

-2*(x-0.5)²=-3.50

(x-0.5)²=-3.50/-2

(x-0.5)²=1.75------> square root both sides

(+/-)(x-0.5)=√7/2

(+)(x-0.5)=√7/2----> (√7/2)+0.5----> x=1.823

(-)(x-0.5)=√5/2-----> x=0.5-(√7/2)----> x=-0.823

the solutions are

x=1.823

x=-0.823

Rewrite the logarithm expression into exponential form

zhannawk [14.2K]

Answer:

$\frac{1}{25}$ = $5^{-2}$

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$ , thus

$log_{5}$ ( $\frac{1}{25}$ ) = - 2, then

$\frac{1}{25}$ = $5^{-2}$

What is the percent increase between getting a high school scholarship and bachelors degree when high school scholarship is $421

gogolik [260]

Answer:

The percent increase between getting a high school scholarship and bachelor's degree is 59.14%.

Step-by-step explanation:

Given:

High school scholarship is $421.

Bachelor's degree is $670.

Now, to find the percent increase between a high school scholarship and bachelor's degree.

So, we get the amount of increase between a high school scholarship and bachelor's degree.

$670-421=249.$

Thus, the amount of increase = $249.

Now, to get the percent increase between a high school scholarship and bachelor's degree:

$\frac{249}{421}\times 100$

$=\frac{24900}{421}$

$=59.14\%.$

Therefore, the percent increase between getting a high school scholarship and bachelor's degree is 59.14%.
