Solve the equation for x.

x + 13 = 22​

Answers

Answer 1

x + -13 = 22

Reorder the terms:

-13 + x = 22

Solving

-13 + x = 22

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '13' to each side of the equation.

-13 + 13 + x = 22 + 13

Combine like terms: -13 + 13 = 0

0 + x = 22 + 13

x = 22 + 13

Combine like terms: 22 + 13 = 35

x = 35

Simplifying

x = 35

3a^2+8a+4


someone help​

Answers

Answer:

(3a+2) (a+2)

Step-by-step explanation:

3a²+8a+4

ur sum is 8

ur product is 12

6x2 = 12

6+2=8

3a²+6a+2a+4

3a(a+2)+2(a+2)

(3a+2) (a+2)

Start by writing (3a + ) (a + )
+ is determined by the + in the problem
Next think of a number that will multiply to get 4 and add to get 8 (this is multiplied by 3)
The answer is:
(3a + 2) (a + 2)
To check the work expand it to find you get the original function again

Consider the following proportion:

35,000 is invested at 5% compound interest.What is the interest at the end of three years​

Answers

Answer:

$40,516.86

Step-by-step explanation:

start by taking 35,000 and multiplying it by 0.05 to get 5% of the number. then add that number (1,750) to the original 35,000 and you should get 36,750. this would be the first year. Then multiply 36,750 by 0.05 again and add that number (1837.5) to the original 36,750 and you should get 38,587.5. Finally multiply that by 0.05 and add that number (1,929.375) to the original 38,587.5 and you should get 40516.875. Round to the hundredths since it is money.

Answer:

You can follow the image attached. (Although not 100% accurate, since it is roughly an estimate of where the values are.)

Basically, you will indicate with dots (or crosses) the points which fulfill the data in the table. In this case, the x-axis will be the average temp and the y-axis will be the date in april trees bloom.

For example, you can roughly estimate where 1.5 in the x-axis, and follow to find 28 in the y-axis for the first set of data, and continue this for all 8 points.

Use the quadratic function to predict f(x) if x equals 8.

f(x) = 25x^2 − 28x + 585

A. f(8) = 2201

B. f(8) = 2679

C. f(8) = 1614

D. f(8) = 1961

Answers

Answer:

D. f(8) = 1961

Step-by-step explanation:

i know the answer it is i think

To predict f(x) when x equals 8 we simply substitute.  

So f(x) = 25x2 28x + 585  

f(8) = 25 (8)^2 - 28 (8) + 585

f(8) = 25 * 64 - 224 + 585

f(8) = 1600 - 224 + 585 = 1961

Hencse f(8) = 1961

Hloo friend^_^..___

Q= f(x) = 25x2 − 28x + 585

Solution

________

f(8) = 25*(8)^2 - 28*8 + 585

= 25*64 - 224 + 585

= 1600 - 224 + 585

= 2185-224

= 1961 Ans...

So the correct ans is f(8) = 1961...

Triangles ABC has vertices A(1,-1) B(1,-5) and C(5,-5). A dilation with a scale factor of 0.25 and true center at (-3,3) is applied to the triangle. What are the coordinates of A’B’C’ in the dilated image?

Answers

Answer:

A'(-2, 2)B'(-2, 1)C'(-1, 1)

Step-by-step explanation:

For scale factor k and center of dilation (p, q), the transformation is ...

  (x, y) ⇒ (kx +(1-k)p, ky +(1-k)q)

For k=1/4 and (p, q) = (-3, 3), the coordinates are transformed to ...

  (x, y) ⇒ (1/4x -9/4, 1/4y +9/4)

Then the preimage points are dilated to ...

  A(1, -1) ⇒ A'(1/4 -9/4, -1/4 +9/4) = A'(-2, 2)

  B(1, -5) ⇒ B'(1/4 -9/4, -5/4 +9/4) = B'(-2, 1)

  C(5, -5) ⇒ C'(5/4 -9/4, -5/4 +9/4) = C'(-1, 1)
