Answer:
3x^2+17x+20
Step-by-step explanation:
Answer: x = y
y = -4
y = 3x + 2
x = 8
Simplify: (-3a2b5)2
Find (x - 4)2`Find the product: (3x + 5)(4x - 1)
Use FOIL:
F: 3x*4x=12x^2
O: 3x*-1 = -3x
I: 5*4x = 20x
L: 5*-1 = -5
Combine these products to get:
12x^2+17x-5
------------------------
Which of the following is the equation of a vertical line?
x = y
y = -4
y = 3x + 2
x = 8
Answer x=8 ; The graph is the set of points where x=8.
-----------------------
Simplify: (-3a2b5)2
=(-3a^2b^5)(-3a2b^5)
=9a^4b^10
------------
Find (x - 4)^2
=(x-4)(x-4)
Use FOIL to get:
x^2-4x-4x+16
=x^2-8x+16

MATH HELP!!!! I HAVE POSTED THIS QUESTION AND NO ONE ANSWERS! 15 POINTS!!!
Answer:
A
Step-by-step explanation:
in order to find the answer take into mind what the question is asking for.
The equation has to pass the point (12,3) and has to be parallel to y=(4/3)x+5.
since the equations have to be parallel you can take out D since it has the reciprocal of the slope of the original equation.
You could also take out the negative equation C since the original one is not negative.
then you would have to graph the equations and would find that A is the answer because in order to have a point (12,3) you need to either start from the negative y-axis and ascend or from the positive axis and descend but B doesn't go down it goes up since it has a positive y value and has a positive slope. So in conclusion the answer would be A.

Brian has $100 in his pocket. As he is walking home 1/4th of the money falls out of his wallet. Of the remaining money, he uses $15 to buy girl scout cookies. Lastly, of the remaining money he loses 1/3rd. How much money does he have left by the time he makes it home?
Answer:
$40
Step-by-step explanation:
Brian starts at $100, then loses 1/4th of the money,
100/4 = 25,
then you subtract 25 from 100, which gives you 75
With the remaining $75, he spends $15 on girl scout cookies,
75 - 15 = 60
He then has $60 remaining, but while walking home, loses 1/3 of the total amount.
60/3 = 20,
you then subtract 20 from 60, which gives you 40
Therefore, $40 is what is remaining.

A plane at an altitude of 7000ft is flying in direction of an island. If they angel of depression is 21 from the plane to the island, what is the horizontal distance until the plane flies over the island?
Answer:
The horizontal distance until the plane flies over the island is 2687ft
Step-by-step explanation:
An illustrative diagram of the scenario is shown in the attachment below.
P is the position of the plane, I indicates the position of the island and G is point on the ground such that /PG/ is perpendicular to the ground.
From the diagram, the horizontal distance from the plane to the island is x.
x = /IG/
In the diagram, consider triangle PIG which is a right angle triangle.
/PI/ is the hypotenuse
/IG/ is the opposite
and /GP/ is the adjacent.
From the formula,
[tex]tan\theta = \frac{opposite}{adjacent}\\[/tex]
∴ [tex]tan\theta = \frac{/IG/}{/GP/}\\[/tex]
[tex]tan\theta = \frac{x}{/GP/}\\[/tex]
∴ [tex]x = /GP/ tan\theta[/tex]
From the diagram
/GP/ = 7000 ft and [tex]\theta = 21[/tex]
∴ [tex]x = 7000 \times tan21\\[/tex]
[tex]x = 2687.05 ft[/tex]
[tex]x[/tex] ≅ 2687 ft
Hence, the horizontal distance until the plane flies over the island is 2687ft
A box of chocolates contains 18 chocolate squares. Ten of the squares are milk chocolate, 5 are dark chocolate, and 3 are white chocolate.
If Christina randomly chooses a chocolate out of the box, what is the probability of her choosing a white chocolate square?
a. 1/8
b. 1/6
c. 5/18
d. 1/3
Answer: 1/6
Step-by-step explanation: 1/6 she has 3/18 chance of drawing a white chocolate. There are 3 white chocolates out of a total of 18 chocolates. That’s 3/18 which is equal to 1/6

-2x - 8y = 16
Y = -4
Answer:
_24
step by step explanation
-2x-8×4=16
-2x-32=16
the -32 will go the other way and it will become positive
-2x=32+16
-2x=48
-2×/2=48/2
=-24
Answer:
8
Step-by-step explanation:
-2x-8y=16 -2(8)-8(-4)=16
-2x-8(-4)=16 -16+32=16
-2x+32=16 16=16
-2x=-16
x=8

Cody is a lawyer who used to charge his clients $170 per hour. Cody recently reconsidered his rates and ultimately decided to charge $136 per hour. What was the percent of decrease in the billing rate?
Answer:
20%Step-by-step explanation:
Step one:
given data
initial charge = $170 per hour
new charge= $136 per hour.
Required
% decrease
Step two:
% decrease = initial- new /inital charge
% decrease = 170-136 /170*100
% decrease = 34 /170*100
% decrease = 0.2*100
% decrease = 20%
lan has 30 star stickers to share. she gives 4 stickers to each of her and has 2 stickers.
how many friends does lan have.
Answer:
7
Step-by-step explanation:
this can be written as an equation, which is 4x+2= 30
X = the number of friends
30= the total of stickers
4= the stickers each friend gets
2= the amount lan gets.
Now solve the equation, first subtract 2 on both sides, which is 28
4x=28 now divide both sides by 4, which will give you 7
x= 7, that means that answer is 7

Item 11 A rate of 4 centimeters per second is equal to how many meters per hour? 4 centimeters per second = meters per hour Item 11 A rate of 4 centimeters per second is equal to how many meters per hour? 4 centimeters per second = meters per hour
Answer:
Step-by-step explanation:
This can be done with dimensional analysis.
4 cm/s [ 1 m/100cm][3600 sec/1 hour]
4 cm* 3600s / 100 cm = 4 m *3600 seconds / hr
144 m / hour. All the numbers and units cancel out.
