- 6y + 19 = 1 + 5 + 7y
Ok so first, let's combine the like terms on the right side by adding them
1 + 5 + 7y \\  = 6 + 7y
Now we look at them put back together
- 6y + 19 = 6 + 7y
Now you have to move all your y's to one side and numbers without a variable to the other. So, for this we're going to add 6y to 7y on the right so the left side cancels out.
19 = 6 + 13y
On the other side we subtract 6 from 19
13 = 13y \\ 13y = 13
and now to get the answer for y we divide 13 by 13 to get your answer of 1 :)
y = 1

The equation x^2/121 + y^2/1. what points are the vertices of the eclipse
Alla [95]
Answer:

(-11,0) and (11,0).

Step-by-step explanation:

The given ellipse has the equation:

\frac{x^2}{121}+\frac{y^2}{1}=1

This can be rewritten as

\frac{x^2}{11^2}+\frac{y^2}{1^2}=1

We compare this to the general equation of the ellipse:

\frac{x^2}{a^2}+\frac{y^2}{b^2}=1

We have a=11 and b=1

The vertices of this ellipse are at (-a,0) and (+a,0).

Therefore the vertices of this ellipse are at (-11,0) and (11,0).

The correct choice is A.

The verticles of a polygon p(0,4), q(5,4), r(5.-3) and s(0,-3). What are the perimeters of the polygon
makkiz [27]

Answer:

Following are the responses to the given question:

Perimeter of polygon:

PQ = 5\\\\RS = 5\\\\PR = QS=\sqrt{74} = 8.60\\\\QR = 7

Step-by-step explanation:

In this question we calculate the perimeter of a polygon which can be defined as follows:

Using formula:

d = \sqrt{(x _2 - x_1)^2 + (y_2 - y_1)^2}

When vertices are:

P ( 0 , 4) \\\\Q(5 , 4)

x_1 = 0\\\\y_1 = 4\\\\x_2 = 5\\\\y_2 = 4\\\\PQ = \sqrt{( 5 - 0)^2 + ( 4 - 4)^2}\\\\= \sqrt{5^2 + 0^2}\\\\= \sqrt{25}\\\\= 5

R( 5 , -3) and S ( 0 , -3)x_1 = 5y_1 = -3x_2 = 0\\y_2 = -3\\RS = \sqrt{ ( 0 - 5)^2 + ( -3 - (-3))^2}\\= \sqrt{( -5)^2 + ( -3 + 3)^2}\\= \sqrt{ 25 + 0}\\= \sqrt{25}\\= 5\\P( 0 , 4)\ and\ R (5 , -3)\\x_1 = 0\\y_1 = 4\\x_2 = 5\\y_2 = -3\\PR = \sqrt{( 5 - 0)^2 + ( -3 - 4)^2}\\= \sqrt{5^2 + (-7)^2}\\= \sqrt{ 25 + 49}\\= \sqrt{74}\\= 8.60\\

Q ( 5 , 4) \ and \ S(0 ,-3)\\x_1 = 5\\y_1 = 4\\x_2 = 0\\y_2 = -3\\QS =\sqrt{ ( 0 - 5)^2 + ( -3 - 4)^2}\\= \sqrt{-5^2 + -7^2}\\= \sqrt{25 + 49}\\= \sqrt{74}\\= 8.60

Q( 5,4\ and\ R(5 , -3)\\x_1 = 5\\y_1 = 4\\x_2 = 5\\y_2 = -3\\QR = \sqrt{(5 - 5)^2 + ( -3 - 4)^2}\\=  \sqrt{0^2 + (-7)^2}\\=   \sqrt{0 + 49}\\=  \sqrt{49}\\= 7\\

Find the point of intersection for the pair of linear equations.<br> x +y = 0.3<br> y=3x + 16.7
Nookie1986 [14]

Answer:

B

Step-by-step explanation:

You should find the solution for this system of equations (The value of x is the first coordinate for the point of intersection, the value of y is the second coordinate for the point of intersection)

X+y=0.3

y=3x+16.7

use 3x+16.7 instead of y in the first equation(do it to get only x in the first equation)

x+3x+16.7=0.3

4x+16.4=0

4x=-16.4

x=-4.1

y=0.3+4.1=4.4

B
