John says the transformation rule (x, y) es002-1.jpg (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to

the image (0, ???2). What was his error?

Answer:

The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

Step-by-step explanation:

The transformation rule should be applied to the pre-image.

The application of the rule results in the point (8, 12).

The transformation rule was applied to the wrong point.

We are given transformation rule

(x, y) --> (x + 4, y + 7).

The coordinate of the pre-image is (4,5).

The coordinate of the transformed image is (0,-2).

Please see, if we apply

(x, y) --> (x + 4, y + 7) rule.

(4,5) coordinate would become (4 +4 , 5+7 ) = (8,12).

But we need (0,-2) instead of (8,12).

Let us reverse operation in the given rule and check.

Let us change (x + 4, y + 7)  to (x-4, y-7) and now check.

(4,5) coordinate would become (4-4 , 5-7) = (0,-2).

So, we got exact coordinate of the transformed image.

Therefore, error was

(x, y) --> (x + 4, y + 7) rule should be (x, y) --> (x - 4, y - 7) rule.

6(8-x)(x+4)=0 what’s the solution set?
Travka [436]

Answer:

x_{1} = -4\\\\x_{2} = 8

Step-by-step explanation:

6(8-x)(x+4)=0

(48 -6x )(x+4) = 0

48x +192 -6x^2 -24x = 0

6x^2 -24x -192=0

using quadratic formula:

x =\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}

a= 6   b= -24  c= -192

we have:

x_{1} = -4\\\\x_{2} = 8

Alex has obtained $1,000 and he takes it to the bank where the account is compounded monthly at 5%. He will leave it for 10 year
Vesnalui [34]
A = P(1 + R/N) to the power of nt
where A = amount
P=principal 
R= rate
N= number of times per year interest is compounded
and nt = time in a year
1000( 1 + 5%/12) to the power of 10 = $1042.46
