Find the vertex and axis of symmetry of each quadratic equation.

Mathematics
1 answer:
icang [17]1 year ago
4 0

Answer: Vertex (-2,-15) and therefore the axis of sym will be -2

Step-by-step explanation: Using -b/2a you can deduce that 4x^2 is a, 16x is b and 1 is c. So -b/2a = -16/8 = -2. Then you plug -2 for y and yu should get -15. Then x will be your axis of symetry to x=-2

Consider the function y = x2 − 18x. Enter the values for the variables to complete the inverse.
ollegr [7]
<span>In the function "y=x2-18x" the goal is to find the value of the letter x. We know that y equals x2-18x. First, recognize that x2 is the same thing as 2x. So changing the problem to "y=2x-18x". We can subtract 18x from 2x, which leaves us with -16x. Now the problem looks like this: y=-16x. In order to get x by itself, we will need to do the same thing to both sides of the equation. In this case, we want the answer to be x by itself, or (1x) which is the same thing. We divide both sides of the equation by (-16). We are left with the following: y/-16=x. Basically, in words, x equals y divided by negative 16.</span>

Ishaan to have a score of 97 on the next exam have an overall average of 85

What is the mean of exam scores?

The mean of exam scores is the sum of the scores divided by the number of exams taken, more like an average of all scores

Initially, average score on 4 exams is 82

average=total score/number of exams

average score on 4 exams=82

total score =unknown=assume it is

number of exams=4

82=x/4

x=4*82

x=328

In order to have an overall average score of 85, we would sum the total score of 4 exams and the fifth exam and divide by 5 exams

85=(328+y)/5

85*5=328+y

425=328+y

y=425-328

y=97
