(7 – 7n³) – (6 + 6n²)
1 answer:
Step-by-step explanation:
To open the bracket you need to multiply the first bracket numbers to the 2nd bracket's number.
THE QUESTION WILL ONLY BE SOLVED ON THE BRACKETS ARE OPEN.....thnk me later
1st number with multiply with the other two
2nd number with aslo mutiply with the other two
STEP:1
Open the brackets after doing the following info as mentioned above. Then you will arrange them in order
STEP:2
First will come the number with power 3 then power2 and
then the last one comes the normal number
STEP:3
You will now solve the numbers after arranging them as given in the picture.
I hope you are clear with the explanatin i have done.
THANK YOU!

Answer:
x + 5 = -3
x=-10
- -2x -4 +8x -12
2(3x - 8)
Step-by-step explanation:
1-
Multiply both sides of the equation by 5: 4x + 25 = -15
Move the constant to the right-hand side and change its sign : 4x = -15 - 25
Calculate the diffrerence: 4x = -40
Divide both sides of the equation by 4 : x= -10
2-
Collect like terms: 6x-4-12
Factor out 2 from the expression : 2(3x - 8)
Answer:
the expression of this function is:
Step-by-step explanation:
This graph corresponds to an absolute value function, which as you can see has the minimum (vertex) at the point (1, -1) on the plane, and also that goes through the origin of coordinates (0, 0)
therefore, notice that from the point (0, 0) to (1, -1) there is a slope of "-1" which is going to characterize the steepness of the x- variable that resides inside the absolute value function. since the vertex has also moved from the characteristic (0, 0) in the function:
then we have to include a horizontal shift to the right in one unit (by subtracting 1 units from x), and a vertical shift downwards one unit (by subtracting 1 from the full absolute value expression) in order to shift the vertex to the position (1, -1):
Answer:
<h2>slope = 4</h2>Step-by-step explanation:
The formula of a slope:
We have the points (9, 10) and (7, 2).
Substitute:
