Step-by-step explanation:

Answer:

vertex = (1, - 5 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

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

y = (x - 1)² - 5 ← is in vertex form

with (h, k ) = (1, - 5 ) ← vertex

Answer:1 and 1/3

Step-by-step explanation:

Answer:

Undefined?

Step-by-step explanation:

x^2-12x+20=(x-2)(x-10)

x^2-12x+20=x^2-10x-2x-20

-12x+20=-12x-20

20=-20

40=0

[tex]3x - 2y = - 16[/tex]

Subtract sides -3x

[tex]3x - 3x - 2y = - 3x - 16[/tex]

Simplification

[tex] - 2y = - 3x - 16[/tex]

Negatives simplifies

[tex]2y = 3x + 16[/tex]

Divided sides by 2

[tex] \frac{2y}{2} = \frac{3x + 16}{2} \\ [/tex]

[tex] \frac{2}{2}y = \frac{3}{2}x + \frac{16}{2} \\ [/tex]

Simplification

[tex]y = \frac{3}{2}x + 8 \\ [/tex]

This is the slope-intercept form.

Answer:

y = [tex]-\frac{1}{5}[/tex]x - 4

Step-by-step explanation:

Given parameters:

   Coordinates  = (5, -5)

 Equation of the line, x + 5y = 20

Unknown:

Equation of the line parallel to this= ?

Solution:

To find the equation of the line, we must first understand that parallel lines are lines having the same slope. They do not cross each other at any point.

The equation of any straight line is given as;

          y = mx + c

y and x are the coordinates

m is the slope

c is the y- intercept

  Now,

         x + 5y = 20

  Let us find the slope of this line;

            5y  = -x + 20

Divide through by 5;

            y  = [tex]-\frac{1}{5}[/tex]x + 4

The slope of the new line is the coefficient of x;

  Slope =  [tex]-\frac{1}{5}[/tex]

So, let us find the y-intercept of the new line;

          -5 = [tex]-\frac{1}{5}[/tex] x 5 + c

          -5 = -1  + c

           c = -5 + 1   = -4

Now,

    y = [tex]-\frac{1}{5}[/tex]x - 4

Answer: y = -(1/5)x - 4

Answer:

1) Is the pattern an arithmetic sequence?​

Yes it is

2)Identify a and d.​

a = First term = 2

d = Common difference = 2

3) Write the 50th term of the sequence.​

50th term = 100

4) Find the total number of logs in the first 10 rows.​

= 1010 logs

Step-by-step explanation:

Is the pattern an arithmetic sequence?​

Yes it is

2) Identify a and d.​

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,

The formula for arithmetic sequence =

an = a+ (n - 1)d

a = First term

d = Common difference

For the above question:

a = 2

d = Second term - First term

= 4 - 2

d = 2

3) Write the 50th term of the sequence.​

Using the formula for arithmetic sequence

an = a+ (n - 1)d

a = 2

n = 50

d = 2

a50 = 2 + (50 - 1)2

= 2 + (49)2

= 2 + 98

= 100

The 50th term = 100

4)Find the total number of logs in the first 10 rows.​

Sum of first n terms = n/2(a + l)

n = 10

a = first term = 2

We are told that there are 200 logs in the bottom row, hence:

l = last term = 200 logs

Hence,

Sn = 10/2×[ (2 + 200

= 5(202)

= 1010 logs

Answer:

the ratio is 2:11

Step-by-step explanation:

I already wrote this in a comment, but I'm writing it here because the other person's answer was deleted.

when all the measurements of the ingredients are added together, that makes 11.

according to the recipe, there's 2 cups of mixed nuts.

so the ratio is 2 cups of mixed nuts to 11 cups of granola.

Answer:

June 7   Purchased candy & coke       $3.47                                $X - $4.87

June 8   Tip received                                                 $25             $X + $20.13

June 8   Purchased headphones        $14.80                               $X + $5.33

Answer:

Total amount (A) = $3,955

Step-by-step explanation:

Given:

Initial deposit (P) = $3,500

Rate of interest  (r) = 3.25%

Number of years (t) = 4

Find:

Total amount (A)

Computation:

Simple interest = (p)(r)(t)

Simple interest =  (3,500)(3.25)(4)

Simple Interest = $455

Total amount (A) = Initial deposit (P) + Simple Interest

Total amount (A) = 3,500 + 455

Total amount (A) = $3,955

The tree's growth rate is 10in per year

Ten years after Planting, it is 140 inches tall

Step-by-step explanation:

original(slope intercept form) : y = 10x + 40

y = 10(10) + 40

y = 100 + 40

y = 40

Answer:

1.87 miles

Step-by-step explanation:

[let's say x = how many miles]

18.99 + 75x = 159.24 [write out the equation]

-18.99 -18.99 [subtraction property of equality]

75x = 140.25

___ ____ [division property of equality]

75 75

x = 1.87

Answer:

See below

Step-by-step explanation:

(-4, 8) has to be the solution.

1st equation: -4x+8y = 1

2nd equation: 8x - 4y = 1

These should work. Do the matrix-substitution combo method to see:

-4  8  1

.8 -4  -1

Reduce and and matrix-substitution combo:

1 0 -4

0 1  8

The reduced eckerd form of the matrix shows that the solutions are (-4, 8)

Therefore it -4x + 8u = 1 and 8x - 4y = 1 are the two equations for the system.

If Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.

If Garvin lets the account go for 90 days, he will exceed the 60-day free credit period by 30 days. This means he will be charged interest on the outstanding balance for those 30 days.

Since there is no information provided regarding any payments or partial payments made by Garvin within the 60-day period, we can assume that the full $500 is still outstanding.

Using the formula for simple interest:

Interest = Principal x Rate x Time

Principal = $500

Rate = 12% per year = 0.12

Time = 30 days / 365 days (since the rate is an annual rate)

Interest = $500 x 0.12 x (30/365) = $4.11 (rounded to two decimal places)

Therefore, if Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.
