Answer:
we know that,
Force is directly proportional to rate of change of momentum.

angie read 3 books in 5 days and each book contains 410 pages if angie reads if angie read the same number of books each day how may pages did she read a day
a.90
b.410
c.1,230
d.246
Answers
Answer:
D-246 pages.
Step-by-step explanation:
To find the total number of pages, you must do 3*410 which = 1,230. 1,230 is the total number of pages so then you divide that by 5 because there are 5 days so 1,230/5 = 246. So 246 pages per day.
ANSWER 246
410*3(books)=1230 /5(days) =246

Write an  equation of the line that passes through please (2, -2) and is parallel to line y=3x+9
Answers
Answer: y=3x-8
Step-by-step explanation:
To find the parallel line, you know that the slope must stay the same. If the slope is different, the graphs will touch at one point. This goes against parallel lines as they NEVER touch or cross.
y=3x+b
We can use the given point to find the y-intercept.
-2=3(2)+b [multiply]
-2=6+b [subtract both sides by 6]
b=-8
Now that we have found the y-intercept, we can finish our equation.
y=3x-8

Given the function y= 2x if x>0 x−3 if x≤0 . Find its values for x=1; 3; 0; −2. Answer: If x = 1, then y = . If x = 3, then y = . If x = 0, then y = . If x = −2, then y = .
Answers
Answer:
Step-by-step explanation:
Given the function y= 2x if x>0 and x−3 if x≤0, to find the value of the function for x = 1, we will substitute x = 1 into the function y = 2x since x>0 at that point.
If x = 1;
y = 2(1)
y = 2
Hence when x = 1, y = 2
If x = 3, we will still use the function y = 2x since 3 is still grater than 0 satisfying the condition x>0.
y = 2(3)
y = 6
Hence when x = 3, y = 6
when x = 0, since x is zero, we will substitute x = 0 into the function x-3 because x≤0 at this point.
If y = x-3
y = 0-3
y = -3
Hence when x = 0, y = -3
when x = -2, we will substitute x = 0 into the function x-3 because -2 is also less than zero
If y = x-3 for x≤0
y = -2-3
y = -5
Hence when x = -2, y = -5

Answer:
31
Step-by-step explanation:
Recognize that all angles of a triangle add up to 180 degrees, so your equation would be x + 16 + x + 24 + 78 = 180.
Step 1: Combine like-terms.
2x + 118 = 180
Step 2: Subtract 118 from both sides to isolate the variable.
2x = 62

Write the equation g(x) of the transformation of the parent graph f(x) = |x| stretched vertically by a factor of 4 and translated up 2 units.
Answers
Answer:
g(x) = 4|x| +2
Step-by-step explanation:
f(x) = |x|
y = f(x) + C C > 0 moves it up
g(x) = |x| +2 moves it up 2 units
y = Cf(x) C > 1 stretches it in the y-direction
g(x) = 4|x| +2 stretch by 4
We start off with: f(x) = |x|
c > 0 means move up
y = f(x) + c
2 units up
After: g(x) = |x| + 2
c > 1 means y-direction stretch
y = cf(x)
4 unit stretch
After: g(x) = 4|x| + 2

Morris borrowed $6 from his mother. so far, he has repaid $4. if debt is represented as a negative number, what number sentence shows the amount of jack's remaining dept.?
Answers
if it was negitive I would be -2
Step-by-step explanation:
so 6-4=2 and if you make that negative it would be -2
Answer:
-$6 + $4 = -$2
Step-by-step explanation:
Since Morris borrowed 6 dollars to begin with, the first term in my equation is -6$, representing the debt he has incurred from taking a loan of 6 dollars from his mother. After paying $4 dollars, he would still be in debt of $2 to his mother. Since he is still in debt of 2 dollars, the furthest right term in my aforementioned equation is -$2.
