Using a minimum of two sentences, describe how to write the function, f(x) = (x 2)2 - 3, in standard form.

Answers

The function is a quadratic function, and the standard form of a quadratic function is ax^2 + bx + c

The standard form of the function [tex]\mathbf{f(x) = (x - 2)^2 - 3}[/tex] is [tex]\mathbf{f(x) = x^2 - 4x + 1}[/tex]

The function is given as:

[tex]\mathbf{f(x) = (x - 2)^2 - 3}[/tex]

Factor out (x - 2)^2

[tex]\mathbf{f(x) = (x - 2)(x - 2) - 3}[/tex]

Expand the expression

[tex]\mathbf{f(x) = x^2 - 2x -2x + 4 - 3}[/tex]

Simplify the like terms i.e. add -2x and -2x

[tex]\mathbf{f(x) = x^2 - 4x + 4 - 3}[/tex]

Simplify the like terms i.e. add 4 and -3

[tex]\mathbf{f(x) = x^2 - 4x + 1}[/tex]

Hence, the standard form of the function [tex]\mathbf{f(x) = (x - 2)^2 - 3}[/tex] is [tex]\mathbf{f(x) = x^2 - 4x + 1}[/tex]

money raised from the sale of tickets. How much money was raised if the fundraiser fsold 246 adult tickets and 380 children's tickets?
Let a = the number of adult tickets and let c = the number of child tickets. Then, an algebraic expression for the total money raised from the sale of tickets is

Answers

Answer:

x is amount of money

c + a = 646

John scored 75% of the total marks How many marks did he get​

Answers

Given :-

John scored 75% of the total marks .

To Find :-

How many marks did he get .

Solution :-

Let us say that the maximum marks for the exam was x . So he got 75% of x that is ,

[tex]\longrightarrow[/tex] Marks = 75% of x

[tex]\longrightarrow[/tex] Marks = 75/100 × x

[tex]\longrightarrow[/tex] Marks = 3/4 × x

[tex]\longrightarrow[/tex] Marks = 3x/4

Hence he scored 3x/4 marks in the test.

Sam made $189 for 9 hours of work. At the same rate, how many hours would he have to work to make S147?​

Answers

Answer:  7 hours

Step-by-step explanation:

$189/9 hr = $21/hr

$21/hr(x) = $147

x = 147/21

x = 7 hours

Answer:

7 hours

Step-by-step explanation:

We know 9 hours of work paid $189

to find how much Sam makes in one hour we divide the amount made by the time it took to make it

189 / 9    = 21 dollars per hour

then we know she would like to make $147 more at a rate of $21/hr so

147 / 21   = 7 hours

A painter charges $15.80 per hour, plus an additional amount for the supplies. If he made $190.89 on a job where he worked 7 hours, how much did the supplies cost?
A.
$110.60
B.
$80.29
C.
$90.29
D.
$27.27

Answers

Answer:

B

Step-by-step explanation:

First find out how much he made without the supplies. To do this you would multiply $15.80 by the 7 hours he worked. This gives you 110.60. Then subtract 110.60 from the 190.89 the job cost. You would then overall get 80.29 for the supplies

Answers

We make use of the identity,

a² - b² = (a - b) (a + b)

with a = 5 and b = 7i. Multiply the numerator and denominator by the complex conjugate of 5 + 7i, or 5 - 7i :

(-8 + 3i)/(5 + 7i) = (-8 + 3i)/(5 + 7i) • (5 - 7i)/(5 - 7i)

(-8 + 3i)/(5 + 7i) = (-8 + 3i) (5 - 7i) / (5² - (7i)²)

(-8 + 3i)/(5 + 7i) = (-8 + 3i) (5 - 7i) / (25 - (-49))

(-8 + 3i)/(5 + 7i) = (-8 + 3i) (5 - 7i) / 74

Expand the numerator on the right side:

(-8 + 3i)/(5 + 7i) = ((-8)•5 + 3i•5 + (-8)•(-7i) + 3i•(-7i)) / 74

(-8 + 3i)/(5 + 7i) = (-40 + 15i + 56i - 21i²) / 74

(-8 + 3i)/(5 + 7i) = (-40 + 71i - 21(-1)) / 74

(-8 + 3i)/(5 + 7i) = (-19 + 71i) / 74

Write the equation of a line that is parallel to the line y=−4x+1 and goes through the point (2,0).

Answers

Answer:

y=-4x+8

Step-by-step explanation:

Hi there!

We are given the line y=-4x+1, and we want to write the equation of the line that is parallel to that line and that also passes through the point (2, 0)

Parallel lines have the same slope, so it makes sense to find the slope of the line y=-4x+1

The line is written in the format y=mx+b, where m is the slope and b is the y intercept.

As -4 is in the place of where m should be, the slope of the line is -4.

It's also the slope of the line parallel to it.

We can write the slope of the new line in slope-intercept form as well; this is the line so far, after substituting -4 as m:

y=-4x+b

Now we need to find b, which is the value of the y intercept

Remember that are given the point (2,0), which we can use to help solve for b; substitute 2 as x and 0 as y.

0=-4(2)+b

Multiply

0=-8+b

Add 8 to both sides

8=b

Substitute 8 as b into the equation:

y=-4x+8
