Answer:

The correct option is 4.

Step-by-step explanation:

The given relation is

y=-4x^2-8

We have to find the values output if input is 2.

Substitute x=2 in the given relation.

y=-4(2)^2-8

Solve the above equation.

y=-4(4)-8

y=-16-8

y=-24

The value of output is -24 at x=2. Therefore the correct option is 4.

Describe when to use a series and when to use an equation.
anyanavicka [17]

Answer:

An equation is used when we have paired sets of data to describe how the values in one pair change when we alter the values in the other set.

On the other hand, a series gives a general formula of determining the value of the nth observation when the values have been arranged in increasing order

Step-by-step explanation:

An equation such as; y = 3x+5 models the relation between the response variable y and the predictor variable x. It tells us how y changes when x is altered by a certain magnitude. The value 3 is described as the slope while 5 is the y-intercept.

On the other hand, a series such as;  score = 2 + 3n provides a general formula that can be used to determine the score of the nth individual in a sample or population.

Answer: A

Explanation:
First you have to write the model in an equation form.

6x+5=15

Subtract 5 from both sides

6x=10

Divide 6 from both sides

X=10/6

Simplify

X=5/3 or 1.67
