Add or subtract like terms
2x+3y=5x-y
7x=2y
since you can’t divide or add any more like terms together there isn’t anything else to solve

Answer:

(1.33,0)

Step-by-step explanation:

2x+3y=5x-y

subtract 5x from both sides

-3x+3y= -y

multiply both sides by -1

3x-3y= y

divide both sides by y

3x-3=1

add 3 to both sides

3x=4

divide by 3

x=1.333,

then as given y=0

so therefore

(1.33,0)

Write the equation for a parabola with a focus at (-8, -1) and a directrix at y = − 4.
Sidana [21]

Answer:

y = 1/6 x^2 + 8/3 x + 49/6

Step-by-step explanation:

This is a parabola which opens upwards.

The distance of a point (x, y)  from the focus is

√[(x -  -8)^2  + (y - -1)^2] and

the distance of the point from the line y = -4

= y - -4

These distances are equal for a parabola so:

√[(x -  -8)^2  + (y - -1)^2] = y + 4

Squaring both sides:

(x + 8)^2 + (y + 1)^2  = (y + 4)^2

x^2 + 16x + 64 + y^2 + 2y + 1 = y^2 + 8y + 16

x^2 + 16x + 64 + 1 - 16 = 8y - 2y

6y = x^2 + 16x + 49

y = 1/6 x^2 + 8/3 x + 49/6 is the equation of the parabola.

What is a Subset(It should be in the simplest form)
NISA [10]

Answer:

1 : a set each of whose elements is an element of an inclusive set. 2 : division, portion a subset of our community.

Step-by-step explanation:

In mathematics, set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion

hope this helps

Which of these equations have no solution? Check all that apply.
dlinn [17]
First one simplifies to 2x + 6 = 2x + 7  which can't be true   so this one has No Solution.
Same applies to the second equation  ( 5x + 15 = 5x - 15) No solution

also the last one has no solution because it simplifies to  4x + 20 = 4x + 19
