6000 because 254 is less than 400 so it rounds down. If it was more than 500 it would round up.
Answer:
x- intercepts are - 8 and 8
Step-by-step explanation:
to find the x-intercepts set f(x) = 0, that is
x² - 64 = 0 ( this is a difference of squares )
(x - 8)(x + 8) = 0 ← in factored form
equate each factor to zero and solve for x
x - 8 = 0 ⇒ x = 8
x + 8 = 0 ⇒ x = - 8
Answer: 2(x+y)-25
Step-by-step explanation:
First, we need to show the sum of Roger and Olivia's heights. If Roger is x and Olivia is y, the sum is <em>x+y</em>
Next, we need to double that. To double something we multiply it by 2. Since we need double the expression we found above, we put it in parentheses. So the doubled sum is shown as <em>2(x+y)</em>
Finally, we need to show that Isabella is 25 centimeters shorter than the doubled sum. To do that, subtract 25.
The final expression for Isabella's height is 2(x+y)-25

ANSWER: 9x = -8
Basically you need to start by removing the “X” on the left side by subtracting the value and adding it onto the other side. Then you need to remove the number from the left side by adding that value to it and subtracting it from the other side. Once you’ve done that you have your answer
