Answer:

It has no solutions.

-2(x+2)=1/4(-8x-4) \

You have to water it down like a normal equation.

-2x-4=-2x-1

& from here you can just tell it won't have any solutions since it is not equal.

Answer:

28

Step-by-step explanation:

Steps 1 : for the top numerator 7!4! =

7! = 7×6×5×4×3×2×1

4!=4×3×2×1

step 2 : for the bottom denominator 3!6!

3!= 3×2×1

6!=6×5×4×3×2×1

step 3 : is to cancel out all number that looks like on numerator over denominator

it will leave you with 7 × 4 only on the numerator = 28

because all the number in the denominator will cancel out with some on the numerator .

I hope it helps

The simplified solution of the factorial expression (7!4!)/(3!6!) is 14/3.

The given expression is

(7!4!)/(3!6!)  

We can simplify it using properties of factorials.

First, let's expand each factorial:

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1

4! = 4 x 3 x 2 x 1

3! = 3 x 2 x 1

6! = 6 x 5 x 4 x 3 x 2 x 1

Now, we can substitute these factorials into the original expression:

(7!4!)/(3!6!) = (7 x 6 x 5 x 4 x 3 x 2 x 1 x 4 x 3 x 2 x 1) / (3 x 2 x 1 x 6 x 5 x 4 x 3 x 2 x 1)

Next, we can cancel out common factors from the numerator and denominator:

(7 x 4)/(3 x 2 x 1) = 28/6

Simplifying:

28/6 = 14/3

Therefore, the simplified solution to (7!4!)/(3!6!) is 14/3.

Answer:

Interest = [tex] \boxed{\$ 789.75} [/tex]

Explanation:

Interest [I] = principle × rate × time [prt]

______________________________

x% = x/100

a b/c = a + (b/c) = (ac + b) / c

______________________

I = prt

I = ($1,950)(4 ½%)(9)

I = ($1,950)(0.045)(9)

I = ($87.75)(9)

I = ($789.75)

I = $789.75

40 = 5 (w - 2)            would be the equation.

40 = 5w - 10              using the distributive property.

+ 10        + 10             because you must add to both sides to get rid of the 10.

50 = 5w

/5      /5                      again, keep the same on both sides, and...

10 = w

Answer:

-9

Step-by-step explanation:

The city of Brussels will be the warmest. The difference in temperature between Oslo and London is -9°C and the temperature at 6:00 pm in Paris will be -2°C.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

(a)

A city which has the lowest temperature will be warmest since -1°C is the lowest so Brussels will have the warmest city.

(b)

The difference in temperature between Oslo and London will be as,

-12 °C - (-3 °C) = -9 °C.

(c)

At 6.:00 pm the temperature will be -5 °C + 3 °C = -2 °C.

Hence "The city of Brussels will be the warmest. The difference in temperature between Oslo and London is -9°C and the temperature at 6:00 pm in Paris will be -2°C".

area = 400 in²

Step-by-step explanation:

parallelogram area  = 20 x 16 = 320

triangle area = 1/2(20)(8) = 80

320 + 80 = 400 in²

Answer:

No, the measurements given cannot be used to create a triangle.

Explanation:

The sum of all the angles of a triangle should be 180°.

Here,

55°+80°+55°=190°

which is not equal to 180°.

So, the traingle cannot be formed using the given measurements.

The average velocities for the given time intervals are,

(i) -8 m/s,

(ii) -12 m/s,

(iii) 4 m/s, and

(iv) 4 m/s. The instantaneous velocity at t = 4 is -8 m/s. The attached graph of s as a function of t is a straight line with slope -8, showing the secant and tangent lines.

a) To find the average velocity in each time interval,

calculate the change in displacement (Δs) divided by the change in time (Δt) within each interval.

s = 12 - 8t + 18

i) [3, 4]:

Δs = s(4) - s(3) = (12 - 8(4) + 18) - (12 - 8(3) + 18) = -8

Δt = 4 - 3 = 1

Average velocity = Δs / Δt = -8 / 1 = -8 m/s

ii) [3.5, 4]:

Δs = s(4) - s(3.5) = (12 - 8(4) + 18) - (12 - 8(3.5) + 18) = -6

Δt = 4 - 3.5 = 0.5

Average velocity = Δs / Δt = -6 / 0.5 = -12 m/s

iii) [4, 5]:

Δs = s(5) - s(4) = (12 - 8(5) + 18) - (12 - 8(4) + 18) = 4

Δt = 5 - 4 = 1

Average velocity = Δs / Δt = 4 / 1 = 4 m/s

iv) [4, 4.5]:

Δs = s(4.5) - s(4) = (12 - 8(4.5) + 18) - (12 - 8(4) + 18) = 2

Δt = 4.5 - 4 = 0.5

Average velocity = Δs / Δt = 2 / 0.5 = 4 m/s

b) To find the instantaneous velocity when t = 4, we'll find the derivative of s with respect to t and then substitute t = 4.

s = 12 - 8t + 18

ds/dt = -8

Instantaneous velocity at t = 4 is equal to the derivative at t = 4:

Instantaneous velocity at t = 4: ds/dt (t=4) = -8 m/s

c) To sketch the graph of s as a function of t and draw the secant lines (average velocities) and the tangent line (instantaneous velocity):

Attached graph.

The graph of s as a function of t is a straight line with a slope of -8 and a y-intercept of 30. At t = 4, the instantaneous velocity is -8 m/s.

Secant lines:

Draw a straight line connecting the points (3, 10) and (4, 2) for the interval [3, 4].

Draw a straight line connecting the points (3.5, 4) and (4, 2) for the interval [3.5, 4].

Draw a straight line connecting the points (4, 2) and (5, 6) for the interval [4, 5].

Draw a straight line connecting the points (4, 2) and (4.5, 4) for the interval [4, 4.5].

Tangent line:

At t = 4, draw a straight line with a slope of -8 and passing through the point (4, 2).

The attached graph will show the secant lines with different slopes as the average velocities in each interval and the tangent line with a slope of -8 as the instantaneous velocity at t = 4.

Answer: B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Let's look at A.

A simplified = 7x - 6

Let's look at B

B simplified = 2 + 7x

Let's look at C

C simplified = -6 + 7x OR 7x - 6

Let's look at D, lastly.

D simplified = 7x - 6

In conclusion, we can see that 7x - 6 is the answer we need to arrive at  to have equivalent expressions. Only B does not have that answer, so B is the answer.
