The only solution is x=12.
Answer:
x-intercept: (18/5,0)
y-intercept: (0,-2)
Step-by-step explanation:
btw .. you put the equation twice it's supposed to be " -5x+9y=-18 "
It's A.
All you need to do is plug in the X from the ordered pair, then solve.
y=-5x-4
y=-5(10)-4
y=-50-4
y=-54
Which is NOT -52, so the answer is indeed A
2/7 x 1/3 = 2/ 21
In simplest form 2/21 = 2/21
Answer + 2/21
Answer: 2x-3=15
2(9)-3=15
18-3=15
