(3/5)x+1=125/27
81x+135=625
81x=490
x=490/81= 6 4/81
Answer: yes
Step-by-step explanation: Because he had a lower number to begin with and they both spent the same amount of money
Answer:
y=(8/9)x + 4 and 2/3
Step-by-step explanation:
the slope of this line:
change in y/change in x
change in y=6-(-2)=8
change in x=-6-3=-9
change in y/change in x= 8/9
8/9 is the slope, so you plug it in for m in the standard form equation. You then use one point's x and y values to substitute for x and y in the equation, and solve for b, which is the y intercept
y=mx+b
y=(8/9)x+b
-2=(8/9)*3+b
-2=8/3+b
-4 and 2/3=b
I'm not to sure if I know the other ones but number 12th Is 6
Step-by-step explanation:
Since the two lines intersect at point Q(x,y) the x & y values of both lines must be equal at point Q. so 3x+14=7x-10. Solving for x yields x = 6.
