Answer:
Step-by-step explanation:
3x+4y=−23.........(1)
x=3y+1 .........(2)
Putting (2) in (1)
3(3y + 1) + 4y = -23
9y + 3 + 4y = -23
9y + 4y = -23 - 3
13y = -26
y = -26/13
y = -2
Putting y into (2)
x=3y+1
x = 3(-2) + 1
x = -6 + 1
x = -5
Answer:
4/3
Step-by-step explanation:
Slope is rise/run so find two points and find the rise/run. (0,-1) and (4,2) so the slope would be 4/3
Answer:
414 tickets!
Step-by-step explanation:
If there were sold 92 adult tickets, and for every two of them, 7 student tickects are sold, we have the following:
92 / 2 = 46
Multiply by 7.
46 * 7 = 322 student tickets.
322 students tickets + 92 adult tickets = 414 tickets in total.

no triangle IJK is not similar to triangle TXZ bcoz sides are not proportionate
Answer:
f(x)=x2,g(x)=f(3x)=(3x)2=9x2
Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric around y axis. When x=1/3 or -1/3, then y=1.
Hope this helps! :))
