Answer:
Step-by-step explanation:
To solve for y, you have to isolate it on one side of the equation.
<h3>12x+3y=9</h3>
<u>First, you have to subtract by 12x from both sides.</u>
<u>Solve.</u>
<u>Then, you divide by 3 from both sides.</u>
<u>Solve.</u>
Use the distributive property.
<h3>⇒A(B+C)=AB+AC</h3>
9-12x=3(3-4x)
<u>Divide the numbers from left to right.</u>
3/3=1
3-4x
<u>Then, rewrite the problem down.</u>
- <u>Therefore, the correct answer is y=3-4x.</u>
I hope this helps! Let me know if you have any questions.
I think the speed is 0 since the slope gives you the value for sped on a distance v time graph and in this case the slope is 0 which means the object is not moving.<span />

Answer:
x = 44
right
Step-by-step explanation:
The sum of the angles in a triangle add to 180
90+ 46+x = 180
Combine like terms
136+x = 180
Subtract 136 from each side
136+x-136=180-136
x =44
Since we have a 90 degree angle it is a right triangle
For this question, we can use proportional reasoning to find out the answer.
Let us call the point at the other end of line and in between the two expressions, D.
Side AB:AC = BD:DC (remember that ratios are the same as division so you can do the exact same thing with division statements instead).
Now substitute: 8:12 = (x+4):(2x+1).
Now solve (if using division instead of ratios, solve regularily for x):
8:12 = (x+4):(2x+1),
8(2x+1) = 12(x+4),
16x+8 = 12x+48,
16x-12x = 48-8,
4x = 40,
x = 10.
Therefore x = 10
