Answer: substitution
Step-by-step explanation:
Substitute 3 in for x for all equations.
3(3)+4 = 13
8(3)-1 = 23
3(3)+4 =13
Add all of the sides together to find the perimeter
13+23+13 =49

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

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
Answers
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.

how many factors of 10 are in 10 of the third power?
Answers
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.
What are the factors?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.

8) Jalyn purchased three different sized drinks. The large was twice as much
as the medium drink. The MEGA drink was $10 more than the large. Jalyn
spent a total of $45 on drinks! Write and solve an equation to determine the
cost of the medium drink.
Answers
Answer:MARK ME AS BRAINLIEST
MEGA Drink = $10+2x
LARGE Drink = 2x
MEDIUM Drink = x
hence, we conclude that
($10+2x) + 2x + x = $45
$10+2x + 2x + x =$ 45
5x + $10 = $45
5x = $45-$10
5x = $35
x = 35÷5
x = 7
MEGA DRINK = (10+2X)
10+2×7
10+14
24
LARGE DRINK = 2X
2×7 = 14
MEDIUM DRINK = X
