Given the system of equations, what is the value of the system determinant?

2x + y = 8

x - y = 10

0-1

0-2

0-3

**Given:**

The system of equation is

[tex]2x+y=8[/tex]

[tex]x-y=10[/tex]

**To find:**

The value of the system determinant.

**Solution:**

If two equations of a system of equations are [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex], then the system determinant is

[tex]D=\left|\begin{matrix}a_1&b_1\\a_2&b_2\end{matrix}\right|[/tex]

[tex]D=a_1b_2-b_1a_2[/tex]

The given two equations are [tex]2x+y=8[/tex] and [tex]x-y=10[/tex].

Here, [tex]a_1=2,b_1=1,c_1=8, a_2=1,b_2=-1,c_2=10[/tex].

[tex]D=\left|\begin{matrix}2&1\\1&-1\end{matrix}\right|[/tex]

[tex]D=(2)(-1)-(1)(1)[/tex]

[tex]D=-2-1[/tex]

[tex]D=-3[/tex]

**The value of the system determinant is -3. Therefore, the correct option is C.**

**Answer:**

Bob wants to order some books from an online bookstore. Each book costs 16.50 and shipping for the entire order is a flat rate of 25.03. Bob can spend no more than 78.00

Answer:

x ≤ 3.210

Bib can buy no more Than 3 books

Step-by-step explanation:

Given that:

Cost per book = 16.50

Total shipping = 25.03

Total budgeted amount = 78

The number of books, x that can be ordered can be represented by the inequality :

16.50x + 25.03 ≤ 78

16.50x ≤ 78 - 25.03

16.50x ≤ 52.97

x ≤ 52.97 / 16.50

x ≤ 3.210

Bib can buy no more Than 3 books

find the domain and range of f(x)= -2x²+3

**Answer is in pictures and work as well**

**Answer:**

you need to know what domain and range mean... so remember domain is the input.... range is the output.. :)

**Step-by-step explanation:**

the input .. "x" in this case.. can be any number .. so the domain is all real numbers.

the output.. or range.. is limited.. b/c the square on the 'x" will always make that number positive.. and then it's multiplied by the negative 2.... so that term will always be negative. : | hmmmm so when is that squred term the smallest it can be? hmmm when it's zero... soooo this function will .. at it's greatest point be 3 and go down from there...

the range is from -∞ to 3

**Step-by-step explanation:**

A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.

True or false??

**Given:**

The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."

**To find:**

Whether the given statement in true or false.

**Solution:**

Area of circle is

[tex]A=\pi r^2[/tex]

Where, *r* is the radius of the circle.

Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is

[tex]A_1=\pi (r_1)^2[/tex]

The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:

[tex]r_2=1.5r_1[/tex]

The area of the new circle is

[tex]A_2=\pi (r_2)^2[/tex]

[tex]A_2=\pi (1.5r_1)^2[/tex]

[tex]A_2=2.25\pi (r_1)^2[/tex]

[tex]A_2=2.25A_1[/tex]

The area of the new circle is 2.25 times the area of the original circle.

**Therefore, the given statement is false.**

how many factors of 10 are in 10 of the third power?

**Answer:2 times 5 equals 10**

**Step-by-step explanation:**

"The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10." From ww.infoplease.com great resource

The required **factor **of 10 in 10 of the **third power **is 3.

A **number **or **algebraic expression **that evenly **divides **another **number **or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

10 of the third power = 10³

10³ = 10×10×10

The expression 10×10×10 has 3, 10's

Thus, the required **factor **of 10 in 10 of the **third power **is 3.
