Answers:
bio = 258
sociology = 169
============================================================
Work Shown:
x = number of bio textbooks
y = number of sociology textbooks
x+y = 427 books sold total
y = x-89 since 89 less sociology textbooks were sold compared to bio
Apply substitution to get the following
x+y = 427
x+x-89 = 427 ... replace y with x-89
2x-89 = 427
2x = 427+89
2x = 516
x = 516/2
x = 258 bio textbooks were sold
y = x-89
y = 258-89
y = 169 sociology textbooks were sold
Answer:
Look below
Step-by-step explanation:
A vertical line doesn't intercept the y-axis, therefore the equation would be x=b in which b is where the line intercepts the x-axis.
D) attached is a picture, I would’ve typed it out but I can’t use the square root symbol
First let us convert 0.01 into fraction:
Now we convert 100 and 4 into perfect squares as follows:
Now we use the property of :
Parallel = same slope
Y = 1/5x + b
Plug in point
-8 = 1/5(-10) + b
-8 = -2 + b, b = -6
Equation: y = 1/5x - 6
