Answer:
17. xy + z = 51
18 yz - x = 18
21. 5z + ( y - x ) = 20
22. 5x - ( y2 - 4x ) = -10
23 . x2 + y2 - 10z = 70
24. z3 + ( y2 - 4x ) = 1
25. y + xz / 2
26 .3y + x2 / z = 30
Step-by-step explanation:
17.(6 x 8)+3=
48+3=51
18.(8 x 3)- 6 =
24 - 6 = 18
21. 15 + ( 8 - 3 )
15 + 5=
20
22 .30 - (64 - 24)=
30 - 40=
-10
23. 36 + 64 - 30
100 - 30
70
24. 9 + (16 - 24 )=
9 + -8 =
1
25. 8 + 48 / 2
56 / 2
28
26. 24+ 36/3
60/3=
30
Answer:
1/11 of a gallon
Step-by-step explanation:
He used 2/11 of 1/2 gallon
2/11 * 1/2 = 1/11 of a gallon

The graph represent a horizontal ellipse with center ,(h,k)=(-1,3)
Length of major axis, 2a =8-(-10) = 18
Therefore, a = 9
And length of minor axis, 2b =5-1 =4
Therefore b=2
The formula that we have to use to find the vertices
(h+-a,k)
(-1+-9,3) = (-1-9,3),(-1+9,3) = (-10,3),(8,3)
You solve for one variable like
y-5x=2
"y=5x+2"
9x+3y=58
and you plug it in into the other equation
9x+3(5x+2)=58
You solve for x and then plug in your answer for x into the other equation
*let's imagine x=8*
then:
y-5(8)=2
and solve for y
