First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.
Answer:
Linear functions change at a constant rate per unit interval. An exponential function changes by a common ratio over equal intervals.
Answer:
0 > -5
Step-by-step explanation:
9w - 4w + 6 > 1 + 5w
add the similar variables
5w + 6 > 1 + 5w
subtract 6 from both sides
5w + 6 > 1 + 5w
-6 -6
5w > 5w - 5
simplify
5w > 5w -5
subtract 5 w from both sides
5w > 5w -5
-5w -5w
simplify
= 0 > -5
