Answer:

  • vertex: (7.5, 2.25)
  • f(x) = -(x -7.5)² +2.25

Step-by-step explanation:

My favorite "technology" for problems like this is the Desmos graphing calculator app or web service. It easily displays the vertex (and/or zeros) of the function.

Of course, vertex form is ...

  f(x) = a(x -h)² +k . . . . . . . . vertex (h, k), leading coefficient 'a'

The solution is found by reading the graph and putting the numbers in the formula. The leading coefficient is copied from the standard form equation.

  • vertex: (7.5, 2.25)
  • f(x) = -(x -7.5)² +2.25

maksim [4K]

The value of expression is 7.

<h3>What is expression?</h3>

An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)

Given:

log 10^{7}

Now, using property of log

log b^{a} = a log b

So,

log 10^{7}= 7 log 10

As log 10 = 1

log 10^{7}= 7 (1)

log 10^{7}= 7

6+8(y-3/5), if y=8/9
Alexeev081 [22]

Answer:

<em>8 14/45</em>

Step-by-step explanation:

First, place 8/9 anywhere there is a y:

6+8(8/9-3/5)

Next, do what is in the parenthesis. Make both fractions have the same denominator.

6+8(40/45-27/45)

And now subtract:

6+8(13/45)

Now, multiply 8 and 13/45:

6+ 104/45

Convert the fraction to a mixed fraction:

2 14/45

Finally, add 6:

8 14/45
