Answer:

x = 30 over 11

Step-by-step explanation:

6(9x-5)-4(3+2x)-3(8x-20) = 24

54x-30-12-8x-24x+6 = 24

22x = 24+36

22x = 60

then divide both sides by 22

x = 30 over 11

Answer:

17

Step-by-step explanation:

After a week he can expect 17 calls.

Given that,
A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent.
This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days.
How many phone calls should she expect after a week is to be determined.

The function which is in format f(x) =aˣ where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

Here,

in 1 week = 7 Days
Now,
D = x
y = 30(0.92)ˣ
now put x = 7
y = 30(0.92)⁷
y = 30 * 0.55
y ≈ 17

Thus, After a week he can expect 17 calls.

Answer:

6°F

Step-by-step explanation:

6+ -1 =5

There are 6° F warmer was it in Chicago than Minneapolis.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We have to given that;

On New Year's Day, the temperature in Chicago was 5°F.

And, That same day, the temperature in Minneapolis was - 1°F.

Hence, The temperature warmer was it in Chicago than Minneapolis is,

⇒ 5° F - (- 1)° F

⇒ 6° F

Thus, There are 6° F warmer was it in Chicago than Minneapolis.

The slope of a line indicates how steep it is calculated mathematically as "rise overrun". It calculates the rate where the variable y changes when the relevant variable changes, and the further calculation can be defined as follows:

Given Points:

[tex](-4,-2) , (-2,-10)[/tex]

To find:

slope (m)=?

Solution:

[tex](-4,-2),(-2,-10)\\x_{1} =-4\\y_{1} =-2\\x_{2}= -2\\y_{2}=-10\\[/tex]

Using formula:

[tex]slope(m)=\frac{y_{2-} y_{1} }{x_{2-} x_{1} } \\=\frac{-10-(-2)}{-2-(-4)} \\\\=\frac{-10+2}{-2+4}\\=\frac{-8}{2} \\=-4[/tex]

Therefore,  the slope is "- 4".

Answer:

368 cm²

Step-by-step explanation:

Bottom: 12 * 10 = 120 cm²

Front and back (square): 2 * (10 * 10) = 200 cm²

Front and back (triangle): 12*8/2 = 48 cm²

Total = 120 + 200 + 48 = 368 cm²

Answer:

21

Step-by-step explanation:

27 - 2m = 27 - (2 x 3) then 27 - 6 is 21, so your answer should be 21.

Answer:

21.4%

Step-by-step explanation:

You would pay back a 21.4%

The simple interest rate on the loan of $1400 is approximately 21.4% per year.

The simple interest can be expressed as:

A = P( 1 + rt )

Where A is accrued amount, P is the principal, r is the interest rate and t is time.

Given the parameter:

Principal P = $1400

Accrued amount A = $2000

Time t = 2 years

Interest rate r =?

Plug these values into the above formula and solve for the interest rate.

A = P( 1 + rt )

[tex]r = \frac{1}{t} * ( \frac{A}{P} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = 0.21428[/tex]

Convert r decimal to R a percentage

R = 0.214 × 100

R = 21.4% per year

Therefore, the rate is approximately 21.4% per year.

Hey there!

Remember, equivalent means equal.

So we need to find some fractions that are equal to 4/7 and 3/5.

We can easily do that.

First, let's take 4/7.

Let's multiply the top & bottom by 2:

8/14

4/7 and 8/14 are equivalent.

Let's multiply the top & bottom by 2:

16/28

We can keep multiplying...

Also, there's no reason why we cannot multiply by 3, 4, 5, 6, 7, 8...

In other words, there are infinitely many fractions equivalent to 4/7.

Same with 3/5:

6/10, 12/20...

Hope everything is clear.

Let me know if you have any questions; if so, please ask.

The function f is defined by f(x) = - |x|, The expression for g (x) will be g (x) =  - |x|+3.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that the function is,

f(x) = - |x|,

Geometric transformation is the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is obtained from the graph that the point for the function g (x) is translated by the 3 units right.

Thus, the function f is defined by f(x) = - |x|, The expression for g (x) will be g (x) =  - |x|+3.
