Answer:
9+x = 2y+14
Step-by-step explanation:
It says 9 plus a number, so plug in x for 'a number', and it says 'is twice a number plus 14'. Plug in '=' for is another variable for 'a number', and last but not least, just put +14 for plus 14
4.5(4-x) + 36 = 202 - 2.5(3x + 28)
Distributive property
18 - 4.5x + 36 = 202 - 7.5x - 70
Combine like terms
-4.5x + 54 = -7.5x + 132
Add 7.5x to both sides
3x = 78
Divide both sides by 3
x = 26
Hi There!
Solution,
Point Slope Form: y - y1 = m(x - x1)
Now you have a reference equation of what the answer should look like.
By looking at the answer choices you can eliminate A.
Tip: When you have a negative number you are going to add. For Example, if you have -8, you will input x + 8 or y + 8.
Tip 2: When you have a positive number you are going to subtract. For Example, if you have 3 you will input x - 3 or y - 3.
We can eliminate B because its not subtracting 3.
We can also eliminate C because its not adding -8.
The best answer choice is D.
Answer,
y – 3 = 6(x + 8)
I hope you understand, so you can do this in the future on your own.
Hope This Helps :)
