Answer:

(x, y ) → (x + 10, y + 10 )

Step-by-step explanation:

Consider the coordinates of C and C'

C(- 7, - 1 ) and C'(3, 9 )

The translation in the x- direction is

- 7 → 3 = 3 - (- 7) = 3 + 7 = 10

The translation in the y- direction is

- 1 → 9 = 9 - (- 1) = 9 + 1 = 10

Then translation rule is

(x, y ) → (x + 10, y + 10 )

Mr wood's monthly expenses was $2.125 after he had reduced it by 15 %the oroginal monthoy expenses was 80% of his monthly income

Nataliya [291]

Answer:

$2.50

Step-by-step explanation:

Let the original monthly expenses be 'x'.

Given:

Reduced monthly expenses = $2.125

Reduction in monthly expenses = 15%

Therefore, remaining percentage of monthly expenses = 100 - 15 = 85%

Now, as per question:

$85\%\ of\ x=2.125\\\frac{85}{100}\times x=2.125\\0.85x=2.125\\x=\frac{2.125}{0.85}=\$2.50$

Therefore, the original monthly expenses of Mr. Wood was $2.50.

Also, we can find his monthly income using the value of 'x'.

As per question, his monthly expenses is 80% of his income.

So, 80% of income = 2.5

Income = $\frac{2.5}{0.80}=\$3.125$

So, his monthly income is $ 3.125

Question 3 (Essay Worth 10 points)

Vika [28.1K]

Answer:

a) $A= Lenght *Width$

And replacing we got:

$A= (3x+10) (4x+5)$

And simplifying we got:

$A = 12x^2 +15x +40x +50 = 12x^2 +55x +50$

b) For this case since the coeficient for the higher degree is 2 then the polynomial is of second degree.

c) We need to remember that the closed property for polynomials tell to us that if we apply any operation between two polynomials we need to obtain and other polynomial. For this special case the property is the sum and after multiply we have another polynomial with a higher degree and then the closed property is satisfied.

Step-by-step explanation:

We know a rectangle has sides measuring (4x + 5) units and (3x + 10) units

Part a

For this case we can find the area like this:

$A= Lenght *Width$

And replacing we got:

$A= (3x+10) (4x+5)$

And simplifying we got:

$A = 12x^2 +15x +40x +50 = 12x^2 +55x +50$

Part b

For this case since the coeficient for the higher degree is 2 then the polynomial is of second degree.

Part c

We need to remember that the closed property for polynomials tell to us that if we apply any operation between two polynomials we need to obtain and other polynomial. For this special case the property is the sum and after multiply we have another polynomial with a higher degree and then the closed property is satisfied.
