Answer: B (slope and y-intercept)
Step-by-step explanation:
They charge $0.10 per meter, so that would be represented as y=0.10x. There is an additional fee of $25 which is the +25. The full equation is y=0.10x+25.
0.10x is the slope, and 25 is the y-intercept. Hope this helps!
3x + (x-2) =10
4x-2=10
4x=12
x=3
y=3-2=1
Answer is D
Answer:
x=1
Step-by-step explanation:
x+3x+5x+7x+...+49x=625
(1+3+5+7+...+49)x=625 (1)
now consider s= 1+3+5+7+...+49
a=1
d=3-1=2
l=49
l=a+(n-1)d
49=1+(n-1)2
49-1=(n-1)2
48/2=n-1
n-1=24
n=24+1=25
s=n/2*(a+l)
s=25/2(1+49)
x=25/2×50
s=25×25=625
from (1)
625 x=625
x=625/625=1
