ask your teacher for help lol
Step-by-step explanation:
yeah
Basically x=2 or just simple its two
Answer: x≤ 11/3
Step-by-step explanation:
Let's solve your inequality step-by-step.
6x+15≤37
Step 1: Subtract 15 from both sides.
6x+15−15≤37−15
6x≤22
Step 2: Divide both sides by 6.
6x
6
≤
22

Answer:
328 pages for the novel
123 pages for the second day
Step-by-step explanation:
Let the number of pages of the novel = x
Raw Equation
(1/4)x + 1/2 (3/4)x + 123 = x
Solution
(1/4)x + (3/8)x+ 123 = x
Change the fractions to common denominators.
(2/8)x + (3/8)x + 123 = x
Add the fractions.
(2/8 + 3/8)x + 123 = x
Subtract (5/8)x from both sides.
(5/8)x + 123 = x
(5/8)x- (5/8)x + 123 = x - (5/8)x
Multiply both sides by 8
123 = (3/8)x
123 * 8 = 3x
Divide by 3
984 = 3x
984/3 = 3x / 3
328 = x
===================
At the end of the second day, she read 3/8 * 328 = 123 pages.
This can be written y-7=-2(x-5)² which is standard form for a parabola of vertex (5,7).
The coefficient is -2 and minus means the parabola is inverted like an upside-down U (that is, ∩) so it opens downwards.
The vertex is a maximum point.
