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.

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

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

height is 6 cm, calculate the radius.
Someone plz help
Answers
Answer:
Step-by-step explanation:
Formula for volume of a circle: V=πr²
If you multiply the circle by height, it becomes a cylinder.
Formula for volume of a cylinder: V=πr²h
Plug in the numbers and get r by itself:
471 = πr²(6)
Divide both sides by 6:
78.5 = πr²
Divide both sides by π:
25 = r²
Square root both sides:
[tex]\sqrt{25}[/tex] = [tex]\sqrt{r} \\[/tex]²
5 = r
Radius is 5 cm

Step-by-step explanation
15.
a. 58* Angle 2 = Angle 4 Angle 1 + Angle 2 = 180*
b. 58* Angle 3 + Angle 4 = 180*
c. 58* Angle 1 = Angle 6
d. 58* Angle 6 = Angle 8
e. 122* Angle 4 = Angle 2
f. 122* Angle 4 = Angle 5
g. 122* Angle 5 = Angle 7
16. Alternate Interior angles. They're equal.
10x - 29 = 8x + 3
2x = 32
Divide by 2 to isolate x
x = 16
double check by putting 16 in for x to see if original statement is true
10 (16) - 29 = 8 (16) + 3
160 - 29 = 128 +3
131 = 131
17. Consecutive interior angles. They equal 180*
13x - 26 + 5x + 8 = 180
18x - 18 = 180
18x = 198
Divide by 18 to isolate x
x = 11
Double check
13 (11) - 26 + 5 (11) + 8 = 180
143 - 26 + 55 + 8 = 180
180 = 180
