Please help don't understand What are the domain and range of the function {(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)}?

A.
Domain: {3, 1, 9, 4}; Range: {5, 7, 11, 4, }

B.
Domain: {3, 1, –2, 9, 4}; Range: {5, 7, 11, 4, –2}

C.
Domain: {5, 7, 11, 4, }; Range: {3, 1, 9, 4}

D.
Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

Answers

domain is the inputs
range is outputs from inuting inputs

normally domain=x
range=y
(x,y)
domain is all first number
range is all second numbers

we have
(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)
remember to ignore repeats
Domain: {-2,4,5,7,11}
Range: {-2,1,3,4,9}

What is the solution to the system?-2x + y + 6z = 1
3x + 2y + 5z = 16
7x + 3y – 4z = 11

Answers

Answer:

x = 4, y = -2, z = 3

Step-by-step explanation:

\left\{\begin{array}{ccc}-2x+y+6z=1&(1)\n3x+2y+5z=16&(2)\n7x+3y-4z=11&(3)\end{array}\right\n\n(1)\n-2x+y+6z=1\qquad\text{add}\ 2x\ \text{to both sides}\ny+6z=2x+1\qquad\text{subtract}\ 6z\ \text{from both sides}\ny=2x-6z+1\n\n\text{Substitute it to (2) and (3):}\n\n\left\{\begin{array}{ccc}3x+2(2x-6z+1)+5z=16\n7x+3(2x-6z+1)-4z=11\end{array}\right\qquad\text{use the distributive property}\n\n

\left\{\begin{array}{ccc}3x+4x-12z+2+5z=16&\text{subtract 2 from both sides}\n7x+6x-18z+3-4z=11&\text{subtract 3 from both sides}\end{array}\right\n\left\{\begin{array}{ccc}7x-7z=14&\text{divide both sides by 7}\n13x-22z=8\end{array}\right\n\left\{\begin{array}{ccc}x-z=2&\text{multiply both sides by (-13)}\n13x-22z=8\end{array}\right

\underline{+\left\{\begin{array}{ccc}-13x+13z=-26\n13x-22z=8\end{array}\right}\qquad\text{add both sides of the equations}\n.\qquad\qquad-9z=-18\qquad\text{divide both sides by (-2)}\n.\qquad\qquad \boxed{z=2}\n\n\text{Put it ot the equation}\ x-z=2:\nx-2=2\qquad\text{add 2 to both sides}\n\boxed{x=4}\n\n\text{Put the values of}\ x\ \text{and}\ z\ \text{to the equation}\ y=2x-6z+1:\n\ny=2(4)-6(2)+1\ny=8-12+1\n\boxed{y=-3}

Bella is baking 34 cookies for the holiday party tonight. She baked 18 before leaving for school and will bake the rest when she returns home.Which equation shows how many cookies Bella will bake when she returns home?

a: 18 = x − 34
b: 34 = 18x
c: 34 = x − 18
d: 34 = x + 18

Answers

Answer: d: 34= x + 18

Step-by-step explanation: 34 is the total, and she already made 18. So this means that it would be 34-18=x. OR 18+x=34 which can also be written as 34=18+x
