Heather writes the equations below to represent two lines drawn on the coordinate plane. –6x + 18y = 0 4x – 12y = 20 After apply
dedylja [7]

Answer:

The equation has no solution; therefore, the system of equations has no solution

Step-by-step explanation:

we have

-6x+18y=0 -----> equation A

4x-12y=20 -----> equation B

we know that

If after applying the linear combination method, Heather arrived at the equation 0 = 60

then

The reason is because both lines are parallel, therefore the system of equations has no solutions

<u>Verify</u>

isolate the variable y in the equation A

18y=6x

y=(1/3)x --------> the slope is 1/3

isolate the variable y in the equation B

12y=4x-20

y=(1/3)x-(20/12)

y=(1/3)x-(5/3) --------> the slope is 1/3

Remember that

If the slopes are equal the lines are parallel

so

The system of equations has no solutions

Camilo estimates the weight of the dog . The veterinarian says that the dog weighs 84 pounds . The percent error in Camillo's es
blsea [12.9K]

Answer:

The estimated weight is in the range:

75.6 pounds \leq Weight \leq 92.4 pounds

Step-by-step explanation:

Since, the maximum error is 10%.

Therefore, the maximum and minimum vales will be 10% more and 10% less than 84 pounds, respectively.

<u>For Maximum Limit</u>:

Weight_{max} = (1.1)(84 pounds)

Weight_{max} = <u>92.4 pounds</u>

<u>For Minimum Limit</u>:

Weight_{min} = (0.9)(84 pounds)

Weight_{min} = <u>75.6 pounds</u>

Hence, the estimated weight is in the range:

75.6 pounds \leq Weight \leq 92.4 pounds
