Answer:

The third one.

Step-by-step explanation:

8x(5+2) is also 7x8 so you'd get 56. The 8x5 is 40 then you can do 40+(8x2) which is 40+16 which is = to 56. So the third one is equivalent to each other.

When Richards solved the equation 2(x - 5) = 56 + 6(x - 5), he used the distributive property in step one to write an equivalent
satela [25.4K]

The equivalent equation after applying distributive property will be:

(2*x) - (2*5) = 56 + (6*x) - (6*5)

Further explanation:

Distributive property states that the number is distributed to the sum or difference it is being multiplied to i.e.

a(b+c) = a*b + a*c

So the given equation is:

2(x - 5) = 56 + 6(x - 5)

2 will be distributed to x-5 and 6 will be distributed to x-5

The equivalent equation will be:

(2*x) - (2*5) = 56 + (6*x) - (6*5)\\Simplifying\\2x-10 = 56+6x-30\\2x-6x = 56-30+10\\-4x = 36\\x=-9

Which interval for the graphed function contains the local
Greeley [361]

Answer:

2-[1, 2]

Step-by-step explanation:

From the graph, we can conclude the following things:

1. The graph is of degree 4 as it intersects the x axis at 4 points.

2. The graph tends to infinity for increasing the value of 'x' along positive or negative x-axis.

3. The graph has 3 turning points between the intervals [-1, 0], [1, 2] and [2, 3]

4. Local maximum: The top of mountain of the graph represents local maximum. So, during the interval [1, 2], there is a local maximum.

5. Local minimum: The lowest point or the valley of the graph represents local minimum.

So, during the intervals [-1, 0] and [2, 3], there are local minimums.

Thus, there is only one local maximum during the interval [1, 2].

The original value of a car is $18,000, and it depreciates (loses value) by 15% each year. What is the value of the car after th
Sliva [168]
A reduction of 15% per year means 100-15=85% reducing factor.
1st year: 0.85×18000=$15300.
2nd year: 0.85×15300=$13005.
3rd year: 0.85×13005=$11054.25.
So after 3 years the value of the car is $11054.25 or $11054 to the nearest dollar.
