line given slope = x coefficient = 1/3
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
line slope (m) = -3
line equation formula = y = mx + b
y = -3x + b
from the point given
x = 3
y= 3
3 = -9 + b
b = 12
y = -3x + 12
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
They complete a 900-mile distance with their combined speed of (300+250=550) mph
Therefore, they meet after 900m/550mph=18/11h=1.6364h
Answer:
Cost of selling price = $5.33 (Approx)
Step-by-step explanation:
Given:
Cost of price of cookie = $3 each
Number of cookies = 80
Damaged = 10%
Markup on cost = 60%
Find:
Cost of selling price
Computation:
Total cost of cookie = 80 × 3 = 240
Markup price = 240 + 240(60%)
Markup price = 384
Number of damage cookies = 80(10%) = 8
Remain cookies = 80 - 8 = 72
Cost of selling price = Markup price / Remain cookies
Cost of selling price = 384 / 72
Cost of selling price = $5.33 (Approx)
Answer:
Since is a negative number, so it is on the left of 0 on the number line. 9. ... Sum of and 8 + 8 + 8 Product of and 8 8 8 Now, the required quotient 6. ... Then smaller part (y ) toffees. ...
