Answer:

The solution of the equations is (1,-2).

Step-by-step explanation:

Given : Equations $\frac{7}{2}x-\frac{1}{2}y=\frac{9}{2}$ and $3x-y=5$

To find : What is the solution of the system of equations?

Solution :

Simplify the first equation,

$7x-y=9$ ....(1)

$3x-y=5$ .....(2)

Subtracting (2) from (1),

$7x-y-3x+y=9-5$

$4x=4$

$x=1$

Substitute in (1),

$7(1)-y=9$

$y=-2$

Therefore, the solution of the equations is (1,-2).

Step-by-step explanation:

If you know tangent of theta is 5/3 and it is in the 3rd quadrant, then you know the sides will be going in the negative direction and the real values of the sides would be -5/-3. You can use pythagorean theorem to figure out that the hypotenuse would be sqrt(5^2+3^2) = sqrt(34). Then you can use soh cah toa: sin = opp/hyp, cos=adj/hyp tan = opp/adj. You know that opp = -5, adj = -3, and hyp = sqrt(34) For cosine theta, it would be -3/sqrt(34) and csc is just 1/sin so csc would be hyp/opp = sqrt(34)/-5.

The first five terms of a quadratic sequence are 3, 12, 25, 42, 63.

skad [1K]

Since we know the sequence is quadratic, we expect the $n$ -th term to have the general form

$x_n = an^2 + bn + c$

Plug in the first 3 known values of the sequence to form a system of equations.

$x_1 = 3 = a + b + c$

$x_2 = 12 = 4a + 2b + c$

$x_3 = 25 = 9a + 3b + c$

Eliminating $c$ gives

$(4a + 2b + c) - (a + b + c) = 12 - 3 \implies 3a + b = 9$

$(9a + 3b + c) - (a + b + c) = 25 - 3 \implies 8a + 2b = 22 \implies 4a + b = 11$

Eliminating $b$ gives

$(4a + b) - (3a + b) = 11 - 9 \implies a = 2$

Solving for $b,c$ , we get

$4a + b = 11 \implies b = 11-4\cdot2 = 3$

$a+b+c=3 \implies c=3-2-3 = -2$

So, the $n$ -th term of the sequence is

$x_n = \boxed{2n^2 + 3n - 2}$

Rectangles ABCD and EFGH have the same shape. What is the length oh FG

tangare [24]

The length of FG would be BC. This is because FG and BC corresponds on the shape letter sequence. This would mean that EF would be AB, that GH would be CD, and that HE would be DA.
