One rule in Geometry is the vertical angle theorem. This is when two angles are directly across from each other, they would equal each other. This means that (3x+54) and (7x+10) will equal each other, giving you the function
3x+54=7x+10
Knowing this, all we would need to do now is solve for x. To do this, lets get x to the left. We do this but subtracting both sides by 7x to get rid of 7x on the right side, and bring it to the left
3x+54=7x+10 ------> 3x-7x+54=10 --------> -4x+54=10
Now, lets get x by itself, but subtracting both sides by 54, then dividing both sides by -4
-4x+54=10 ---> -4x=10-54 ---> -4x=-44 ---> x=-44/-4 ---> x= 11
So, we know that x=11. Now, we can plug it into either function. It doesn't matter which one since they both equal each other
f(x)=7x+10 ---> f(11)=7(11)+10 = 77+10 = 87
Our answer is 87
You are right yeeeeeeeeeeeeeeeeeeeeeeeet
Answer:
Step-by-step explanation:
- subtract 5 from both sides of the function
- divide 2 from both sides
- then at this point you're supposed to get -5/2
Answer: He still has to mow 45 lawns, or 75% of the lawns before he is finished.
Answer:
A stem and leaf plot shouldn't be used because the numbers are more than two digits long. These numbers are more varied, so it isn't correct for a stem and leaf plot. The stem is usually the tens digit, and the leaf is the ones digit. When you have four digits, it would get infinite times more hard and complicated. Hope that helped!
