Answer:
Number pencils Ava bought = 2
Explanation:
Price of pen = 2 $
Price of pencil = 1 $
Total money spent = 12 $
Let the number of pen be a and number of pencil be b.
2 a + b = 12 -----------------------------------Equation 1
We have, she bought 3 more pens than pencils
a - b = 3 -------------------------------------- Equation 2
Equation 1 +Equation 2,
2 a + b + a - b = 12 + 3
3a = 15
a = 5
Substituting in equation 2
5 - b = 3
b = 2
Number pencils Ava bought = 2
Answer:
y=\frac{4x}{5}-5
Step-by-step explanation:
linear equation
y=mx+b
We can see that when x=0 y= -5
THis means that b= -5 so we have
y=mx-5
We then know that when x=5 y= -1 so we have
-1=5m-5
Solve this and get m= 4/5
So we have
The slope of the line is 3/4 and the y-intercept is -1
