A)
you square both sides
by squaring the left side, you get rid of the square root leaving only x one that side. But you also need to square the other side because whatever you do to one side you have to do to the other.

Answer: x=o/a^2

b)
To get o on its own on one side you multiply a. You basically do the opposite of what a originally does to cancel it out. So originally, a is dividing o so if you do the opposite, a will multiply on both sides.

a X o cancels out the a, leaving only o.
But whatever you do to one side, you have to do to the other. so Vx (square root of x) has to also be multiplied by a.

Answer: Vx X a=o

c) this is basically the same as b).

apply what i said in b) to this and you will get your answer

to cancel out o, you multiply both sides by o.
because o is getting divided, you will have to do the opposite which is multiply o.

Answer: Vx X o=a

Lemur [1.5K]

Answer:

The correct answer is that a rose bush costs $10 and a shrub costs $4

Step-by-step explanation:

To solve this, start by writing equations for what each spent. Use x for the cost of a rose bush and y for the cost of a shrub. Below would be the equations for each.

Rob: 8x + 5y = 100

Amy: 8x + 8y = 112

Now to find the cost, we multiply Rob's equation by -1 and add them together. This will get x to cancel and allow us to solve for y.

-8x - 5y = -100

8x + 8y = 112

------------------

3y = 12

y = 4

So we know the cost of a shrub is $4. Now we can plug that in to either of the original equations and solve for the rose bush cost.

8x + 5y = 100

8x + 5(4) = 100

8x + 20 = 100

8x = 80

x = 10

Which means that a rose bush costs $10.

What is the equation of the axis of symmetry of this parabola? y=-5(x+4)^2+3
Ede4ka [16]

Answer:

x=-4

Step-by-step explanation:

Given the equation of parabola

y=-5(x+4)^2+3

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point (-4,3)

This parabole goes downwards in y-direction (the leading coefficient -5 is negative)

<u>The axis of symmetry</u> of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Thus, the equation of the axis of symmetry is

x=-4

25-2z-10z=-3(4z+8)-1<br> solve and how many solutions ?
choli [55]
Distribute first
25-2z-10z=-12z-24-1
combine like terms
25-12z=-12z-25
add 12z to both sides
25=-25
no solution because the right side has a negative
