16a. 21cm. bc when it has 10 grams it moves half of that to 5cm so divide 42 by 2 and you get 21cm
17. remember y=mx+b; m is slope and b is y-intercept
you have to put your equation from point slope to y=mx+b
4x+y=6
subtract 4x from each side
y=-4x+6
slope = -4
y-intercept= 6
hope this helped :)
Given:
this year's population: 400 students
next year's population: 120% of this year's population
this year's population x rate of next year's population = next year's population
400 students * 120% = 480 students CHOICE D.
There will be 480 students next year.
Answer: 25
<u>Step-by-step explanation:</u>
7(x - y) - 3(2 + 2x)
= 7x - 7y - 6 - 6x
= x - 7y - 6
for x = 3, y = -4
3 - 7(-4) - 6
= 3 + 28 - 6
= 31 - 6
= 25
Answer:
p = 8
Step-by-step explanation:
