It is not appropriate because it isn't reflective of the points on the right side and its deviation from the points, which has an obvious positive correlation, is too great to be a line of best fit. To make it better, make it less steep and start the line close to the origin.

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$

What is the value of y if log <base 5> <index -7> = y?

Dvinal [7]

Answer:

Hence, the value of y is undefined.

Step-by-step explanation

$log_{5} (-7) = \frac{log(-7)}{log(5)}$ from the property, log_a (b) = (log(a))/log(b).

The value log (-7) was not defined. So, the entire log value also not defined.

Hence, the value of y is undefined.

Mrs. Salas drives 115 miles per week to give 9 voice lessons. She deducts the cost of eight gallons of gasoline at $2 per gallon

ladessa [460]

the answer is $299. If you write an equation, it would be x=35(9)-16. $35 each for 9 lessons. And 2*8= 16.

x=35(9)-16

x=315-16

x=299
