Answer:
x = -8
y = 9
Step-by-step explanation:
to solve this expression using simultaneous equation, we would say let
y =9............................................. equation 1
6x + 5y =-3............................................equation 2
substitute equation 1 into equation 2
-3 = 6x + 5y............................................equation 2
6x + 5(9) = -3
6x + 45 = -3
collect the like terms
6x = -3-45
6x = -48
divide both sides by the coefficient of x which is 6
6x/6 = -48/6
x = -8
therefore y = 9
x = -8
Im pretty sure you need to divide 155 by 4 or 48. try it and see what you get. then ask your teacher if you did it right. always ask questions.
When two fractions have the same denominator, you can compare which fraction is greater by just comparing the numerators.
For example, if you have 2/5 and 3/5, the denominators are the same. So you can just look at the numerators. 3 is greater than 5, so 3/5 is greater than 2/5.
The reasoning to this is that the two numbers are divided by the same number (5), so you can compare the original numbers (numerators).
Answer:
y+2= 3(x+1)
Step-by-step explanation:
First you need to find slope by using y2-y1/x2-x1
you should get 3 for your slope(m)
Them you chose any point iḿ using (-1, -2)
The formula for point slope form is...
y-y1=m(x-x1)
plug those numbers in and you get
y + 2 = 3(x + 1)
