Step-by-step explanation:
Here's a completely valid trick for finding the equation of this new line:
Start with the given 2x + 4y = 6. Replace that '6' with 'C.' We need to find C. To do this, replace x with 6 and y with 4 and calculate C:
2(6) + 4(4) = C, or 12 + 16 = C. Thus, C = 28, and the desired equation is
2x + 4y = 28, or (in simplified form) x + 2y = 14
Answer:
Required equation is 
.
Step-by-step explanation:
Given,
Height of the tree=5x+6
Distance from feet of the tree=2x-4
To find straight distance from feet of Madeline to top of the tree.
Let the tree as y-axis and distance from base along x-axis. Then the distence of straight line from foot of Madeline to top is become the hypotenuse of the triangle. Thus if we let,
Distance from feet of Madeline to top of tree= p, then, according to law of finding third side of a triangle we get,
Hence the result.
Answer:
-3a^2 + 11a
Step-by-step explanation:
= 4a + -3a^2 + 7a
combine like terms
= -3a^2 + 11a
Answer:
4+(x*4)
Step-by-step explanation:
Answer:
Step-by-step explanation:
hello,
I understand that there are only 4 cards and then the player draw a card out of the 4 cards, replace it so the second draw is still out of the 4 cards
<u>How many ways can you draw two cards?</u>
as the first card is replaced, this is 4*4=16
so there is 16 possibles ways
hearts hearts
hearts clubs
hearts diamonds
hearts spades
clubs hearts
clubs clubs
clubs diamonds
clubs spades
diamonds hearts
diamonds clubs
diamonds diamonds
diamonds spades
spades hearts
spades clubs
spades diamonds
spades spades
<u>out of these 16 ways, how many have same colour for both cards?</u>
I assume that there are only two colours Red and Black, so we can have
only 8 ways so the first probability is 8/16 = 1/2
<u>out of these 16 ways, how many are red ace first and black ace?</u>
There are 4 ways so the probability is 4/16 = 1/4
hope this helps
