Rae made a mistake when she added 7. In order to simplify the 7 on the right hand side, it should have been subtracted from both sides.

Rae was the one who made the mistake when she added 7 when it was suppose to be subtracted, to be able to simplify the equation properly and solve for x

Hope this helps :)

<h3>What is a Fraction ?</h3>

When a number is represented by p/q , where q ≠ 0 is called a fraction.

The given fraction is

\rm \dfrac{\sqrt{75}}{\sqrt {15}}\\\\\\\\dfrac{\sqrt{3*5 *5}}{\sqrt {3*5}}\\\\\\\sqrt{5}\\

Can someone help me with this?
yulyashka [42]

Answer:

Step-by-step explanation:

We need to find the error first.

We can do this by subtracting, to find the difference

2.4-1.9 = 0.5

the difference, or error, is 0.5

Now we find a percentage that describes how much more 2.4 is than 1.9

We can create an equation to solve this

2.4 = 1.9 Times x

Now we need to find the value of x

x= 1.2632

now we double check

1.9 Times 1.2632 = 2.4

Now we round to a whole number

1.2632 = 1

To convert a number to a percentage, you need to bring the number over a decimal point.

so 1 becomes .1, or 10 percent

If y = ax² + bx + c is the general form of a quadratic function, what is y = a(x - h)² + k? *
Ierofanga [76]

Step-by-step explanation:

it is the vertex form.

remember, (h, k) is the vertex point.

the vertex being the point of the (quadratic) parabola, where the curve turns around.

depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.

so, the first a. is correct.

and so is the second a., as they play an important role when completing the square and hence finishing the transformation.
