Answer:
Your number is -10
Hope this helps :)
Step-by-step explanation:
Let x be the number
Twice a number is 2x
Added to 7 means + 7 so 2x + 7
Is means =
2x+7=
At this point I have to assume you mean
"is the same as three subtracted from THE SAME number"
Otherwise, rather than a number, we end up with the
equation of a line....
2x + 7 = x - 3 subtract x from both sides
x + 7 = -3 subtract 7 from both sides
x = -10
Your number is -10
Check: 2x+7 = x-3
2(-10) + 7 = -10-3
-20+7 = -13
-13 = -13
The answer fits the parameters of the problem.
Answer:
1
Step-by-step explanation:
1 to the power of anything is still one
1 * 1 * 1 * 1 = 1
(2·3.5 + 4·3.25 + 2·1.9 + 1·1.2)·(1 - 0.05) = $23.75
5*23
Note 23 = 20 + 3
5*23 = 5*(20 + 3) and by distributive property
5*23 = 5*20 + 5*3 = 100 + 15 = 115
= 115

Hello!</h2>
The answer is:
<h2>Why?</h2>
If we want to find an equation of a line parallel to the given line, we must remember that parallel lines has the same slope.
So,
Line equation is:
Where:
So, we are given the function:
Where:
m=-5
Also, we are given the point where the line passes through (0,8), we can use it to find "b"
So, the equation will be:
To prove if we are right, let's substitute (0,8):
Have a nice day!
