Dos numeros naturales se diferencian en 7 unidades y la suma de sus cuadrados es 289

Mathematics
1 answer:
NeTakaya3 years ago
6 0

Answer:

15 y 8

Step-by-step explanation:

y = x - 7

x² + y² = 289

sustituir: x² + (x - 7)² = 289

distribuir: x² + x² - 14x + 49 = 289

sustraer + simplificar: 2x² - 14x - 240 = 0

dividir: x² - 7x - 120 = 0

x² - 15x + 8x - 120 = 0

(x - 15)(x + 8) = 0

x = 15, x = -8 --> x ≠ -8 porque -8 no es naturales

sustituir: y = 15 - 7

simplificar: y = 8

Which products have the same sign as (Negative 2 and StartFraction 3 over 7 EndFraction) (Negative StartFraction 6 over 11 EndFr
Nimfa-mama [501]

Multiplication is the process of multiplying. The products that have the same sign as the product of -2 3/7 and -6/11 are B and D.

<h3>What is multiplication?</h3>

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The product of two positive numbers and the product of two negative numbers both are positive while the product of a negative number and a positive number is negative. Therefore, the product of -2 3/7 and -6/11 is positive, since both are negative.

A.) 3/8 × (-6/7) = Negative

B.) 1 2/9 × 2 6/17 = Positive

C.) -9/20 × 3 4/5 = Negative

D.) -1/3 × -2/3 = Positive

Hence, the products that have the same sign as the product of -2 3/7 and -6/11 are B and D.

alukav5142 [94]

Answer:

The mean change of the stock price of those 5 days is $1.34.

Step-by-step explanation:

First let's list the differences then find the mean.

1.20, 2.30, 1.00, 1.80, 0.40

Now we add up all of the numbers and divide by how many numbers there are.

Mean = 1.34

The mean change of the stock price of those 5 days is $1.34.

The area model represents the quotient of 108 ÷ 9. Which equation shown by the area model can be used to find the quotient?
Rzqust [24]

Solution :

Given that the area model that represents a quotient of 108 ÷ 9.

So, we multiply 9 by multiples of 10 to \text{estimate the quotient.}

10       20      30       40      

90      180     270     360    

Because 108 is between 90 and 180, the quotient lies between 10 and 20.

Using 10 as the first partial quotient in the area model for 108 ÷ 9,

9 x 10 = 90 ,         so 108 - 90 = 18

Now, 9 x 2 = 18,   so 18 - 18 = 0

∴ 10 + 2 = 12

Therefore, the quotient of 108 ÷ 9 is 12.
