To the nearest square unit what is the area of the regular octagon shown below 26.6

Answer:

y=x-9

y=2x-15

Step-by-step explanation:

To solve this we can just pick a random number for our slope and solve for the y intercept

For example lets say the slope is 1

we know that wehn x=6 y= -3 so we have the following equation

-3= 6+b

B is -9

which means one equation is

y=x-9

We can just repeat this same process

Let's say the slope is 2

-3 = 2*6+b

-3= 12

b= -15

which means taht

y=2x-15

Answer:

x = - 8, x = 6

Step-by-step explanation:

[tex] {x}^{2} + 2x - 48 = 0 \\ \\ {x}^{2} + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8, \: \: \: \: x = 6 \\ [/tex]

Answer:

16 ft

Step-by-step explanation:

We start by converting 1yd to ft,

1yd = 3ft

So in the smaller triangle, we have 3ft, 4.5ft. Using Sine, Cos, and Tan rule. We know that

TanΦ = opposite / adjacent

TanΦ = 3ft / 4.5ft

TanΦ = 0.667

Φ = Tan^-1 0.6

Φ = 33.69

This means that the angle of elevation is 33.69°

Using this angle, and the same tan rule again, we gave

Tan 33.69 = opp/24

0.667 = opp/24

opp = 24 * 0.667

opp = 16 ft

Answer:

$273

Step-by-step explanation:

Given data

Jane worked 38 hours at the grocery store last week and made $296.40

she worked 3 hour less= 38-3= 35 hours

Hence if in 38 hours she made   $296.40

              in 35 hours she will make x

cross multiply

x= 35*296.40/38

x= 10374/38

x=$273

Answer:

Answer:

Equation- s + 456 = 437 (I'm not completely sure if this is what your wanting but it is possible to solve the problem with this equation. if this isn't what you need I can write another)

Step-by-step explanation:

s represents the starting height.

s + 456 = 437

first subtract 456 from either side, 437 - 456 = -19.

s = -19 (I'm not sure if this is correct it's been a few months since I've used variables for equations but I tried)

Answer:

1a.) atlantic

1b.) california

2a.) Tennesee and north carolina

2b.) new mexico

3a.)  Add three and reflect accross the x axis

4.) texas (austin), quadrant 3

5.) alabama

6a.)  texas

6b.) quadrant 4

7.) penslyvannia

8.) reflect accross x and y axis (or rotate clockwise by 180 degrees) then go 8 right and up 3

9.) missouri

9b.) up 1 and right 3

10.) quadrant 3

bonus.) i colored it gray and it's in wisconsin

Step-by-step explanation:

1a.) to reflect over the y axis you keep the y axis but swap the x to a negative

1b.) to reflect over the x axis you keep the x value the same but y's sign is swapped

2a.) I've already explained how to reflect something over the x axis

2b.) I've already explained how to reflect something over the y axis

3a.) ohio lies around (5,3) and montana is around (-5,6)  so to get their just go up (or north?) three and reflect accross the y axis

4.) louisana is around (2,-3) and to rotate 90 degrees clockwise  would make the coordinates (-3, -2) which puts you around Texas

5.) new york's coordinates are around (8,5) to go left 4 and down three puts you at (4,2) to reflect it over the x axis gives you the coordinates (4,-2) which is in alabama

6a.) south dakota is around (-2,5) and to reflect it over the x axis gives you (-2,-5) which is texas

6b.) To reflect (-2,-5) over the y axis gives you (2,-5) which is gives you the fourth quadrant

7.) Kansas is around (-1,2) and to reflect over the y-axis gives you (1,2) and to go 6 right and 2 up gives you (7,4)

8.) new hampshiere is around (9, 6) and to get to texas which is around (-1,-3) so let's flip accross the x and y axis to get (-9,-6), then go 8 right and up 3

9.) idaho is around (-8,5) and to get 6 right gets you (-2,2) and to reflect over the y axis gives us (2,2) which is missouri and to get to ohio would require us to to get to (5,3) which would require us to go up 1 and right 3

10.) mississippi is around (3,-2) and to rotate 90 degrees clockwise puts us at (-2,-3) or (y,-x) which is quadrant 3

bonus.) north carolina is around (7,1), to reflect over the y axis puts us at (-7,1), to go up 5 and 4 right puts us at (-2,5) and to rotate 180 degrees clockwise gives us (2,-5)

Answer:

hope this helps you out good luck

Answer:

step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)

step 2. so the question becomes is C a quadratic

step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4

step 4. write out the y values: -126, -14, 2, 18

step 5. write out the differences: 140, 16, 16

step 6. write out the differences: -124, 0.

step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't

step 8. C is not a quadratic.

Answer:

25/4 or 6.25

Step-by-step explanation:

Given that the general equation of  a quadratic equation is given as

ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.

Hence given x^2-5x-19=0, to complete the square, we add

(-5/2)^2 to both sides following the illustration given.

This is 25/4 or 6.24

Answer: rotation,translation

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.

Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

The solution to the exponential expression is given as follows:

x = 34.29.

The exponential expression for this problem is defined as follows:

[tex]10^{\frac{x}{6}} \times 10^{\frac{x}{8}} = 10^{10}[/tex]

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.

The sum of the exponents is given as follows:

x/6 + x/8 = 4x/24 + 3x/24 = 7x/24.

Hence the equivalent expression is given as follows:

[tex]10^{\frac{7x}{24}} = 10^{10}[/tex]

The function 10^x is an injective function, hence the value of x is obtained as follows:

7x/24 = 10

7x = 240

x = 240/7

x = 34.29.
