Please help what's the answer

Mathematics
1 answer:
Semmy [17]3 years ago
5 0

Answer:

The answer is going to be No, (-1, 2) is only a solution for the equation 2x + 5y = 8

Let's find out if it is a solution first:

3 x -1 - 2 x 2 = -3 - 4 = -7

2 x -1 + 5 x 2 = -2 + 10 = 8

<em>From this, you can tell that (-1, 2) is only a solution to 2x + 5y = 8</em>

Nesterboy [21]
4000000000000000000000^50 is the same thing. Ain't no mathematician wants to simplify that. Mathematicians are lazy. So you would leave it the way it is.

Determine the equation of the circle graphed below.
Rzqust [24]

Answer:

Step-by-step explanation:

(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2}(x−h)

2

+(y−k)

2

=r

2

here

r = 7. (the circle is symmetrical with y - axis )

h = 0. and k = 1

Thus equation of circle is,

(x - 0) {}^{2} + (y - ( - 1)) {}^{2} = {7}^{2}(x−0)

2

+(y−(−1))

2

=7

2

x^2 + (y+1)^2 = 49

Start by setting up equations for the equivalent angles

3z + 2 + 79 = 180

3z = 99

z = 33

3z + 2 = y

3(33)+2 = y

97 = y
