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

Step-by-step explanation:

Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4.

Answer:

y=-14x-4

Step-by-step explanation:

Answer:

y + 4 = - 14(x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = - 14 and (a, b ) = (3, - 4 ) , then

y - (- 4) = - 14(x - 3) , that is

y + 4 = - 14(x - 3)

prime factorization calculator of 326

Positive Integer factors of 326 = 2, 163, 326 divided by 2, 163, gives no remainder. They are integers and prime numbers of 326, they are also called composite number.

326 is a composite number.

Prime factorization: 326 = 2 x 163.

The exponents in the prime factorization are 1 and 1. ...

Factors of 326: 1, 2, 163, 326.

Factor pairs: 326 = 1 x 326 or 2 x 163.

326 has no square factors that allow its square root to be simplified.

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

Answer:

9 and 7

Answer:

7 divided by 2

Step-by-step explanation:

I say 7 divided by 2 because if you round 6 3/4 up one you will get 7 and if you round 1 2/3 up one you get 2 so 7 divided by 2 makes most sense

Answer:

The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!

The law of sins says: a/SinA = b/SinB = c/sinC

For this to be an isosceles triangle then side a must equal side c

so then a/sinA = c/sinC

Then you can divide both sides by a and raise to the power of -1 and you would get angle A = angle C which makes this isosceles.

Answer:

12

Step-by-step explanation:

12×12=144

12 squared equals 144 so square root is 12.

9514 1404 393

Answer:

  12

Step-by-step explanation:

The prime factorization of 144 is ...

  144 = 9·16 = 2·2·2·2·3·3

Grouping pairs of similar factors, we have ...

  144 = (2·2)·(2·2)·(3·3) = (2·2·3)·(2·2·3) = 12·12

  √144 = √(12²) = 12

Answer:

Y is the appropriate variable and the most easiest and convenient to eliminate

name 2x + y = 7 as equation i

and 3/2 x - y = 7/2 as equation ii

then add equation i and ii together

(3/2 + 2) x + y - y = (7 + 7/2)

(7/2) x = (21/2)

x = 3

then put in x = 3 in equation i

4 + y = 7

x = 7 - 4

x = 3

Therefore x = 3 and y = 3

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
