5 1/3 is 64/12 in it's simplest form as a mixed number.

Hope it helps you out! Good luck. :)

Answer:

16/3

That's the answer.

Answer:

y = 2x - 3

Yes, your answer is correct.

Step-by-step explanation:

First, find the slope of the two points by using the slope formula:

        y2 - y1

m = -------------

        x2 - x1

         13 - 5

m = -------------

          8 - 4

         8

m = ------- = 2

         4

To find the y-intercept, plug in values into the slope-intercept formula:

y = mx + b

Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):

5 = (2) (4) + b

5 = 8 + b

-3 = b

b = -3

So, putting everything into the slope intercept formula:

y = 2x - 3

uhhhhhhhhh okay then I guess

Answer: you got to Find the focus of a parabola given its equation. If you have the equation of a parabola in vertex form , then the vertex is at and the focus is . Notice that here we are working with a parabola with a vertical axis of symmetry, so the -coordinate of the focus is the same as the -coordinate of the vertex.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2

Answer:

43

Step-by-step explanation:

Since right angles are 90 degree. 90 - 47 = 43

It looks mirrored, so I am guessing the 47 degree is also at the bottom.

If I'm wrong, I apologize.

Answer:

y=4-1/3x

Answer:

You didnt include the graph oop

Step-by-step explanation:

Answer:

56 degrees

Step-by-step explanation:

we know the right triangle has a 90 degree angle, so we add 90 + 34 to get 124

once we have that down we subtract 124 from 180 to get 56

the reason we subtract from 180 is because the sum of all the angles in a triangle equals 180

Answer:

The shorter piece is 39 inches long.

Step-by-step explanation:

ratio = 3 : 1

3+1=4

156/4 = 39

just to check:

39 x 3 = 117 (the lenght of the longer piece)

117 + 39 =156

Answer:

5

Step-by-step explanation:

if the interest is not compounding then it's called simple interest

which is shown through the following equation

PV(1+it)

plug in what we know and get

50(1+.1*1)

50*1.1=55

which means he'll earn 5 dollars interest in one year

Answer:

-1/8

Step-by-step explanation:

Answer:1/6

Step-by-step explanation:

1 to 6 ok a number greater than 4 is 5 so take away 5 out the 1 to 6 and you will have 1 left so 1/6?

Answer:

8x-(-4x-6)=42

8x+4x+6=42

12x=42-6

12x=36

x=36/12

x=3

substitute in an equation of your choice

8(3)-y=42

24-y=42

24-42=y

-18=y

Step-by-step explanation:

Answer:

x= 4 y= -10

Step-by-step explanation:

8x - y = 42

-4x - 6 = y

rearrange -4x - 6 =y to -4x -y = 6

8x - y = 42

-4x - y = 6

4x = 48

48/4 = 12

x=4

subsitute x with 4 adn solve for y = -22

y= -10

Answer:

441[tex]\pi[/tex] inches squared i think

Step-by-step explanation:

radius = 42/2 = 21 inches

area = [tex]\pi[/tex] x [tex](21)^{2}[/tex]

area = 441[tex]\pi[/tex]

area = 1385.44236

Answer: 468.75

is ya answer

i think

sorry if im wrong

Answer:

468.75

Step-by-step explanation:

First we need to add 25% to 500.00 which is 625.

Next we need to subtract 25% from 625.

Now we have 468.75.

Answer:

$1023.74

Step-by-step explanation:

Joan wants to buy a new TV that costs $1299.99. The store has a discount on the TV for 30% off. The city Joan lives in has a 12.5% sales tax. What will be the total cost of the TV?

Step 1

We find the new price after the discount.

Discount = % Discount × Current price

= 30% × $1299.99

= $389.997

The new discounted price =

$1299.99 - $389.997

= $909.993

Step 2

We calculate the Sales tax

The city Joan lives in has a 12.5% sales tax.

Hence,

The sales tax =

12.5% × $909.993

= 12.5/100 × $909.993

= $113.749125

Step 3

The total cost of the TV is calculated as:

Sales Tax + Discounted price

= $113.749125 + $909.993

= $1023.742125

Approximately = $1023.74

The total cost of the TV = $1023.74
