we have
Find the roots
Equate the function to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
therefore
<u>the answer is</u>
Answer:
x>2
Step-by-step explanation:
3x + 5 < 6x -1
subtract 6x on both sides
3x - 6x + 5 < -1
subtract 5 on both sides
-3x < -1 -5
-3x < -6
divide -3 on both sides
x > 2
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

This is just a porportion. So if 250 meters is 1 meter than: 250/1
And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x
Set them equal to each other 250/1=212/x
Cross multiply: 212=250x
Divide to find x: 212/250=x
x=212/250
x=0.848
So the height of the model, to the nearest 10th would be 0.8 meters.
