Find the value of c that completes the square

x^2-16x+c

Please help me with how to do this, and show me. Thank you.

Answers

Answer:

c = 64

Step-by-step explanation:

Given

x² - 16x + c

To complete the square

add ( half the coefficient of the x- term )² to x² - 16x

x² + 2(- 8)x + 64

= (x - 8)²

Thus

x² - 16x + 64 = (x - 8)² ← a perfect square

with c = 64

Do you think it is easy to determine the solution set of a system of linear equations by graphing? Explain your answer.​

Answers

Answer:

Yes, if you keep all of this in mind... This all came from my lesson during class btw.

Step-by-step explanation:

Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph. When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Answers

Answer:

or 0.29(to the nearest tenth)

Step-by-step explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

Exponents Properties

We need to recall the following properties of exponents:

[tex](a^x)^y=(a^y)^x=a^{xy}[/tex]

[tex]\displaystyle a^{-x}=\frac{1}{a^x}[/tex]

We are given the expression:

[tex]2^m=n[/tex]

We need to express the following expression in terms of n.

[tex]8^m-4^{-m}[/tex]

It's necessary to modify the expression to use the given equivalence.

Applying the property:

Marcel reads 20 pages every other day Xion reads 8 pages every day Amber reads 56 pages every 7 days Francessca reads 55 pages every 5 days Which one of these will get to 350 pages first? State the number of days they will take to complete it.

Answers

Answer:

Marcel reads 20 pages every 2 days.

Then, in one day, she reads:

20/2 = 10 pages per day.

Now, we know that in one day she reads 10 pages, then we can subdivide the number 350 in N groups of 10 pages, each one of these N groups needs one day to be read, then 350 pages will be read in N days:

N = 350/10 = 35 days.

Xion reads 8 pages per day.

Then to read 350 pages, he neds:

N = 350/8 = 43.75 days

Amber reads 56 pages in 7 days.

Then she reads 56/7 = 8 pages per day (Same as Xion)

Then she also needs 43.75 days to read 350 pages.

Francessca reads 55 pages in 5 days.

Then she reads 55/5 = 11 pages per day.

To read 350 pages, she needs:

350/11 = 31.82 days

Then the one that needs less days to read 350 pages is Francessca.

What operation must be used on the exponents in order to simplify the expression? (x^3)^7

Answers

Answer: So the trick I was taught to use was PEMDAS which stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the parenthesis first, followed by exponents if there are any. Multiplication and division are equal. So if there's multiplication and division in the problem, you solve the one closest to the left or start of the equation first. The same rules apply for addition and subtraction. They are both equal so you solve the first one first, even if the subtraction is before the addition.
