Sets II, III, and IV are all representations of functions.
Answer:
option B
Step-by-step explanation:
We have:
3x^2+7x+3 and 5x^2+12x
where
a=3x^2+7x+3
b=5x^2+12x
a+b=3x^2+7x+3 +5x^2+12x
we sum each term:
3x^2+5x^2=8x^2
7x+12x=19x
3+0=3
so we have: a+b= 8x^2+19x+3
finally we have
8x^2+19x+3= option B
Answer:
<h2>(-2, -1)</h2>
Step-by-step explanation:
Convert the inequality to the form y > mx + b:
3x + y > -8 <em>subtract 3x from both sides</em>
y > -3x - 8
Put the coordinates of the points to the inequality and check:
for (-3, 0)
0 > -3(-3) - 8 → 0 > 9 - 8 → 0 > 1 FALSE
for (-2, -1)
-1 > -3(-2) - 8 → -1 > 6 - 8 → -1 > -2 TRUE
for (0, -10)
-10 > -3(0) - 8 → -10 > 0 - 8 → -10 > -8 FALSE
for (2, -16)
-16 > -3(2) - 8 → -16 > -6 - 8 → -16 > -14 FALSE
She is standing in front of a wall which is 10 feet away when she kicks the ball and it hits the wall and comes back to her by the virtue of Newton's third Law of motion! She kicks the ball into the air vertically above her and the ball rises to 10 feet and then comes back to her by the virtue of gravity!
M-7<6
add 7 to each side
M-7 +7 < 6+7
M < 13
this is true for all values of M less than 13
