Hello,

- 6 (x - 2)² - 1

Step-by-step explanation:

- 6 x² + 24 x - 25 = - 6 (x² - 4 x) - 25

= - 6 ( (x - 2)² - 4) - 25

= - 6 (x - 2)² + 24 - 25

= - 6 (x - 2)² - 1

Answer:

x = 47

Step-by-step explanation:

We need to solve for the interior angle measure x. To get x, we know that the sum of the triangles angle measures are 180, so lets write an equation to find x.

\(x+102+31=180\)

Add like terms

\(x+133=180\)

Subtract 133 on both sides

\(x=47\)

To check our work, we can add the angle measures together so we know we got it right.

\(47+102+31=180\)

Answer:

x=48

Step-by-step explanation:

add 102 and 31 then subtract it by 180

The baby gorilla grew 340 grams in the first 10 days. This is an average of 34 grams per day. The baby gorilla grew 340 grams in the next 10 days. This is an average of 34 grams per day. The baby gorilla grew at the same rate in the first 10 days and the next 10 days.

Here is the solution:

340 grams / 10 days = 34 grams per day

340 grams / 10 days = 34 grams per day

34 grams per day = 34 grams per day

Therefore, the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days is 34 grams per day.

Answer:

Ok so as a whole there are 8/8 slices you take 5 away with green peppers so now you have 3 out of the 8 slices and you turn 2 of them into mushrooms.

So you 1 slice left (no toppings).

So in a grand total .625 % of the pizza is Green Peppers.

And the mushrooms have covered .25 % of the pizza and the topping less slice with .125 % so the obvious topping is Green Peppers

Answer:

The jar contains 10 nickels and 10 dimes. Another answer is that the jar contains 4 nickels and 13 dimes.

Step-by-step explanation:

1 nickels = 5 cents

1 dime = 10 cents

1st answer

10 nickels = $0.50

10 dimes = $1.00

So 10 nickels + 10 dimes = $1.50

2nd answer

13 dimes = $1.30  

4 nickels = $0.20

So 13 dimes + 4 nickels = $1.50

=======================================================

Explanation:

I'm assuming you meant to type 8x^2 + bx + 2 = 0

Compare this to ax^2 + bx + c = 0

We have a = 8, b = unknown, c = 2.

We'll use the discriminant formula which is D = b^2 - 4ac to find that

D = b^2 - 4ac

D = b^2 - 4*8*2

D = b^2 - 64

Since we want one real solution, we set the discriminant equal to zero.

D = b^2 - 64

0 = b^2 - 64

64 = b^2

b^2 = 64

b = sqrt(64) or b = -sqrt(8)

b = 8 or b = -8

So the equation 8x^2 + 8x + 2 = 0 has one solution. So does the equation 8x^2-8x+2 = 0

Step-by-step explanation:

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Answer:

true

Step-by-step explanation:

Answer:

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Step-by-step explanation:

The given equation is:

4 = u + at

where u = 17, a = 4, and t = 8.

Substituting the given values, we get:

4 = 17 + 4(8)

Simplifying the right-hand side:

4 = 17 + 32

Combining like terms:

4 = 49

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Explanation

The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.

(angle ABD) + (angle DBC) = 180

(134) + (2x) = 180

2x = 180-134

2x = 46

x = 46/2

x = 23

Answer: x=23 and the angle relation used was supplementary angles

Step-by-step explanation:

first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Answer:

The total amount of money needed to pay off the car after 6 years would be $11,800.

Step-by-step explanation:

Write down the facts:

Interest = $10,000 * 0.03 * 6

This being $10,000, 3% interest rate and over 6 years.

Interest= $1800

This amount we found is the additional amount (interest) you have to pay with the $10,000. Now, to find the total amound we add the interest and $10,000.

Total amount = 10,000 + $1800

Total amount = $11,800

Therefore the total amount paid over 6 years (including the 3% interest rate) would be $11,800. I hope this helped!!!

$11800 is the answer
