Answer:
x = -1
Step-by-step explanation:
3(x+1) = -2(x-1) - 4
3x + 3 = -2x + 2 - 4
3x + 3 = -2x - 2
Add the -2x to both sides
5x + 3 = -2
Subtract the 3 to both sides
5x = -5
Divide both sides by 5
x = -1
The x-coordinate after the rotation is -10
Answer:
To find the result of 300 - 650, we can:
a) do 650 + 300 and keep the result sign
b) do 650 + 300 and invert the result sign
c) do 650 - 300 and keep the result sign
d ) perform 650 - 300 and invert the result sign
Step-by-step explanation:
The correct answer is the letter D .
(perform 650 - 300 and invert the result sign)
300 - 650
300 is more than - 650 on the number line this is because of the negative sign of 650
so we can also write it as 650 - 300 and after getting the require result with put the negative sign to the result, so the result will be -350
Keep the sign of the number with the highest absolute value and subtract from it the lowest absolute value.
- (650 - 300)
Subtract the numbers.
- 350
therefore, the answer is d ) perform 650 - 300 and invert the result sign
When we use this = it means it is the exact
answer
When we use ≈ it means it is an estimated answer and not the exact answer Example 12.4684729572974729758328 ≈ 12
