Answer:
Step-by-step explanation:
On day one = few pages (x)
On day two = twice of pages read on day one (2x)
On day three= 6 less than the page read the first day (x-6)
Total pages read = x+2x+(x-6)=458
4x-6=458
4x=458+6=464
x= 464÷4
x=116
Pages read on day three was 110
Answer:
(a) 3x -y = 7
(b) x +3y = 29
Step-by-step explanation:
(a) The standard form of the given line is ...
3x -y = 5
The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...
3x -y = 3(5) -(8)
3x -y = 7
__
(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).
x + 3y = (5) +3(8)
x + 3y = 29
The easiest way I have for knowing the difference between linear and nonlinear is the exponent value on the variable x. It is important to understand the root word in linear. It is LINE. A straight line, no curves .y = 2x - 3 This is linear because the exponent on x is one. Thus your slope is standard rise over run, like a stair step and simply goes up or down. I hope this helps :D
