Answer 1

Step-by-step explanation:

-2x² + 5x - 3 - (-7 - 9x + 5x²)

= -2x² + 5x - 3 + 7 + 9x - 5x²

= -7x² + 14x + 4.

Hence the coefficient of the x term is 14.

Once upon a time a brave and mathematically-inclined warrior named Al Jebra set out on a quest to rescue the kidnapped Princess Polly Nomial.

First, Al needed to get to the room of the stolen Princess to read the ransom note left behind. The Princess lived in the tower with no stairs (for security purposes, ironically). Al plans to use his 17 ft ladder to climb in a window 15 ft up the tower wall.

How far from the wall should Al position the bottom of the ladder so that the top reaches the window ledge? The ladder is 17 ft long.

Your formula is 108°+54°+X=180°
To find X, add 108° & 54°. The sum is 162°.
Next you need to subtract your sum from 180°.
180°-162°=18°
X=18°

Abi and Ali shared £35 in the ratio 1 : 6.
Work out how much Ali received.

Answers

Answer:

£30

Step-by-step explanation:

To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.

1 : 6 = 1 + 6 = 7 parts

Now divide the total amount of parts by the total amount of money shared

35 / 7 = 5

Now multiply the answer by the value that is appropriate.

In this case, they want you to work out how much Ali recieved.

Ali's value is 6

6 × 5 = £30

hope this helps :)

If Abi and Ali shared £35 in a ratio of 1: of 6, Ali received £210.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that, Abi and Ali shared £35 in a ratio of 1: of 6.

We have to apply operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

Suppose the share of Abi and Ali is 1x and 6x and the total amount they shared is  £35.As a result,

x+6x=£35

7x=£35

x=£5

The amount Ali received is found as,

=6x

= 6×£35

=£210

Thus, if Abi and Ali shared £35 in a ratio of 1: of 6, Ali received £210.

steps : 3 time x which is 3x and 3 times 2 then 9 times 6 which is 54 and 9 times x then add nine to both sides to cancel out the -9x then it’s 12x + 6 = 54 now subtract 6 from both sides and you get 12x = 48 now divide both sides by 12 and you get 4

C.
As the x-values increase, the function increases towards negative infinity.
D.
As the x-values increase, the function increases towards positive infinity.

Answers

Answer:

As the x-values increase, the function increases towards positive infinity.

Step-by-step explanation:

I just did this on study island :D

For the exponential function as the x-values increase, the function increases towards positive infinity.

What is an exponential function?

Exponential function is a function that involves exponents. Exponential function has a constant as its base and a variable as its exponent.

According to the given problem,

f(x) = [tex]3^{x}[/tex]

Let the value of x be -1,

⇒ f(x) = [tex]3^{-1}[/tex]

         = 0.33

Now, let the value of x be 1,

⇒ f(x) = [tex]3^{1}[/tex]

          = 3

Hence, we can conclude, as the x-values increase, the function increases towards positive infinity.

800 ounces because 10 × 30 + 10 × 50 = 800

1,000 ounces because 20 × 30 + 10 × 40 = 1,000

1,100 ounces because 20 × 30 + 10 × 50 = 1,100

The graph represents function 1, and the equation represents function 2:

Function 2
y = 5x + 4
How much more is the rate of change of function 2 than the rate of change of
function 1? (4 points)

Answers

Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.  

5 is the answer.

hope this helps :)

Loosen the soil with a shovel or other garden tool up to 18 inches deep, mixing in organic material. Smooth the soil for an even flower bed. Next, remove the flower from the pot while keeping the root ball intact. Once the plant has been removed from its container, plant the flower in the freshly turned soil, ensuring the top of the root ball is even with the ground. Finally, cover the flower bed with mulch to protect the soil. Consistent watering and replacing the organic matter in the soil annually will ensure healthy flowers that will last for years.5Which sentence best expresses the importance of the organic material to the soil?A.
