Answer:
you must send 25 msgs to have the same cost
Step-by-step explanation:
x = n of messages
15+ (0.25x ) = 20 + (0.05x)
0.2x = 5
x = 25
Answer:
I'm pretty sure that this is correct.
Step-by-step explanation:
this is the equation of a straight line that is generally written
y
=
m
×
x
+
q
m is the slope of the line and is the proportionality coefficient between y and x.
The larger m is, the more the line is hanging
q (-3) is the intercept with the Y axis and is the value you find if you put x=0 (this is the axis y equation)
similarly if you put Y=0 (that is the equation of X axis you find the intercept with X axis that is X= 3/2

Answer:
9
Step-by-step explanation
Sqaure root of 9 is 3, a rational number
x=negative 1
y=1
showing my work Substitute y=2x+3y=2x+3 into 2x+5y=32x+5y=3.
12x+15=312x+15=3
2 Solve for xx in 12x+15=312x+15=3.
x=-1x=−1
3 Substitute x=-1x=−1 into y=2x+3y=2x+3.
y=1y=1
