Answer:
Step-by-step explanation:
odd numbers are 1,3,5,7
number of odd cards=4
Total number of cards=8
Number of cards less than 4=3 {1,2,3}

Answer:
y = 2/3x + 4/3
Step-by-step explanation:
Voy a suponer que necesitas resolver para y.
2x + 3y = 4
3y = -2x + 4
y = -2/3x + 4/3
Answer: a) y=0.50x+15
b) The graph of this equation form on a coordinate plane is a line.
c) Slope =0.50 and y-intercept = 15
Step-by-step explanation:
Let x = Number of miles driven by car
Given: The cost of renting a car for a day is $0.50 per mile plus a $15 flat fee.
a) Total cost = 0.50x+15
If y =total cost of renting the car, then y=0.50x+15 (i)
b) Above equation is similar to y= mx+c (ii) [m = slope , xc=y-intercept] which a linear equation .
So the graph of this equation form on a coordinate plane is a line.
c) Comparing (i) and (ii)
m=0.50 , c=15
Slope =0.50 and y-intercept = 15
