Answer: 1
Step-by-step explanation:
Subtract the equations straight down. So we'll subtract the x terms together
5x - 5x = 0x = 0
meaning the x terms effectively go away after subtraction
Then we do the y terms together in the same exact order
y-3y = -2y
Then finally the right hand side values
6 - (-5) = 6+5 = 11
All of that work done indicates we have 0x-2y = 11 which is the same as -2y = 11. Divide both sides by -2 and we end up with y = -11/2
This answer isn't listed so I'm thinking there's a typo your teacher made somewhere.
Answer:
9.03 = x
Step-by-step explanation:
Since we have the Hypotenuse given and we need to find the value of the adjacent side of the given angle we would use the Cosine Ratio;
Cos(46) =
To solve for "x" we would first have to isolate the "x" all to itself.
To isolate the variable, simply multiply 13 to the both sides of "="
=> Cos(46) * 13 = x
=> 9.03 = x
So you can write the answer in either of the 2 ways mentioned above, if you need a fully simplified answer the second answer would be a better fit. If u just need the Equation the 1st equation would be the better fit.
Hope this helps!
Answer:
If your goal is to factor the expression then it would be:
2 (3x + 5)
If your goal is to simplify the expression then it would be:
6x + 10
Answer:
= 6
Step-by-step explanation:
in the third step, they did 2 x -12 and got 24. It should’ve been -24 since it was a positive times a negative. It shouldve been
-24 - (-30)
-24 + 30
= 6
