It’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.
28+2x=90
-28 -28
2x= 62
x=31
Answer:
a - neither b - perpendicular
Step-by-step explanation:
put them in desmos and look at the lines
The degree is 2 becasuse of the x^2 and there are 3 terms so it is a trinomial.
Answer:
x=3(one solution)
Step-by-step explanation:
2x+2=3x-1
subtract 2 from both sides
2x=3x-3
subtract 3x from both sides
-x=-3
divide both sides by -1
x=3
First you must find a common denominator. In this case 10 will work. You then multiply the top number by whatever you multiplied the bottom number by. This is shown below:
4/5- 3/10 = 8/10- 3/10
You can now solve this to get 5/10. This answer can then be reduced to 1/2.
