To use it, we must solve for 1 variable
it seems to be that they want us to solve for x in firsr equation
x+1/9y=11
minus 1/9y from both sides
x=11-1/9y
sub 11-1/9y for x in other equation
18(11-1/9y)+2y=90
distribute
198-2y+2y=90
198=90
false
therefor there is no solution
(if we were to graph them they would be paraalell, if we rewrote them,they look like this: 18x+2y=192 and 18x+2y=90, obviously, there is no solution)
answer is no solution
Answer:
1, 3, 7, 21
Step-by-step explanation:
21/1 = 21
21/3 = 7
21/7 = 3
21/21 = 1
Answer:
∴ x= 17
Step-by-step explanation:
the total of angel in 90°
∴ 2x+3+3x+2 =90
∴ 5x +5 =90
5x=90-5
5x = 85 (divide both side by 5)
∴ x= 17
Answer:
see explanation
Step-by-step explanation:
the graph has a maximum turning point at (- 2, 2 )
the maximum value is the value of the y- coordinate of the vertex , then
maximum at 2
the domain is the values that x takes, in this case
domain is all real numbers
the range is the values that y can have, in this case
range is y ≤ 2

C. 2 + 0 = 2</span>
