Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)

A textbook store sold a combined total of 228 biology and physics textbooks in a week. The number of blology textbooks sold was three times the number of
physics textbooks sold. How many textbooks of each type were sold?
Step-by-step explanation:
Let us assume p is the number of psychology books and b is the number of biology textbooks.
set up first equation:
we know that the total number of books sold was 393
p+b=393
set up second equation:
we know that there were 79 less biology book sold that psychology so...
p = b + 79
subsitute p in the first equation to solve for b
solve value for p

Solve the equation below. Simplify if necessary.
-4/7v = -8 2/3
Show how you did it please :)
Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12
v = 15 1/6

Answer: Add to eliminate x
Step-by-step explanation:
So if you add to 2 equations you can look at it this way. remove all variables right that leaves you with 10+4=48 and -10-3=-56 right and if you add 10 and -10 you get 0 or 0x so by adding these to equations x is eliminated by adding

In your own words, what is a radical expression?
Answer:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.

Cosx=4/5 what is sin2x cos2x and tan2x
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5
