Answer:
16: y=4x+14 17: 12 18: when you simplify it all individually you get x=3 for both equations. 19: $6.69
Step-by-step explanation:
16:y-2=4(x+3) distribute 4 and get y-2=4x-12. Add 2 to both sides to get y-4x+14.
17:x+2y=4 and 3x+6y=? divide 3x+6y by three and you get x+2y=4. This means you can just multiply the 4 by 3 to get the answer.
18:3x-5=4 and 3x-3=6. For the first one add 5 to both sides to get 3x=9 then divide both side by 3 to get x=3. For the second one add 3 to both sides to get 3x=9. Again divide both sides by three to get x=3.
19: $18-$4.62=13.38 since he wants 2 models divide 13.38 by 2 to get 6.69.
Well put it into an equation,
j * -50 = - 11
first you would divide -50 from both sides making it
j=0.22
0.22 times -50 gives you -11

Answer:
A
Step-by-step explanation:
The Y Intercept is for sure going to be 2 so we can eliminate answer choices B and D
The data shows a negative linear association so we can eliminate answer choice C
Therefore the answer is A
Factor the expression.
f(x)= (x-5)(7x-1)(x+2)
