Answer:
The number of students enrolled in 2012 is approximately 17,400,000 to the nearest 100,000
Step-by-step explanation:
y = 0.1967x + 15.66
x = years since 2003
y = number of students enrolled in millions
In 2012, x = 9 (2012 is 9 years from 2003)
y = 0.1967(9) + 15.66
y = 1.7703 + 15.66 = 17.4303 millions = 17,430,300 = 17,400,000 to the nearest 100,000
A. set the top equation as x=something. you can do this by transforming functions.
answer x=2y-8
Then you substitute 2y-8 for x in the bottom problem. 4(2y-8) - 8y= 10.
Solve for y. you will get a false equation. -32=10. Proved.
B. we know that the lines are parallel. if the line don't have a solution that means that they don't intersect. that means they must be parallel because parallel lines never intersect.
I think this question is technically asking

Answer:
t = 0
Step-by-step explanation:
(7t - 2) - (-3t + 1) = -3(1 - 3t)
because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally
[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]
will be
7t - 2 + 3t - 1 = -3 + 9t
add like terms
10t - 3 = -3 + 9t
subtract 9t from both sides
t - 3 = -3
add 3 to both sides
t = 0
Answer:
x = 15
Step-by-step explanation:
f(x) = 4x² + 7x
= 4(-3)² + 7(-3)
= 36 + (-21)
= 15
