Answer:
C: x=-8
Step-by-step explanation:
The line is perpendicular to the X so you use the X value.
im not for sure but I think the answer is 9! my reasoning is below,,
Step-by-step explanation:
![\frac{49}{7} = \frac{63}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B49%7D%7B7%7D%20%20%3D%20%20%5Cfrac%7B63%7D%7Bx%7D%20)
do the crossing method and it would result in this
(49×x) = (63×7)
after simplifying both sides
49x = 441
divide both sides by 49 and the result will be
x = 9 !!
Answer:
It is C Trust me i am doing the same thing in school and got it right
Hello! For this question, you solve using order of operations, which you probably already have remembered as PEMDAS. Anytime a number is raised to the 0 power, that is equivalent to 1. 0.5^0 is 1. 250 * 1 is 250. x = 0 gives us the answer of 250. Now, let's solve for the number by the second power. 0.5² is 0.25. 250 * 0.25 is 62.5. x² gives us 62.5. Now, let's subtract the two numbers together. 250 - 62.5 is 187.5. Because the number is decreasing, the slope is negative, so the answer is -187.5. Your answer is correct.
Answer:
Slope= -4
Step-by-step explanation:
Slope is rise over run (y over x)
So, looking at the table, you can see that every time the y values went down by 8, the x values went up by 2.
So, the slope can be written as:
-8/2
Simplified to -4/1 or just -4
