Find some graphing paper and graph away..
i.e. Sub in x = 0 and find what y = ?
y = 1/2(0) + 3
y = 3
So we know the coordinate (0,3)
When x = 4 , y = ?
y = 1/2(4) + 3
y = 4/2 + 3
y = 2 + 3
y = 5
So we know another coordinate (4, 5)
When x = -4, y = ?
y = 1/2(-4) + 3
y = -4/2 + 3
y = -2 + 3
y = 1
So we know another coordinate (-4, 1)
Putting it all together, the coordinates: (-4, 1) , (0, 3) and (4, 5) should be plenty sufficient to graph and then draw a line of best fit connecting them.
Answer: the wise man is 79
Step-by-step explanation:
400 - 3x = 163
400–163 =3x
237 = 3x or 3x = 237 or x = 79…
Answer:
and 
Step-by-step explanation:
Given:
Equation 1:
Simplifying the above equation by dividing both sides by 100
Equation 2:
Simplifying the above equation by dividing both sides by 400.
Now the system of equation is:
(1a) 
(2a) 
Solving by elimination
Multiplying equation (2a) with 
(2b) 
Adding equations (1a) and (2b) in order to eliminate 
+
We get 
∴
Plugging in equation (2a).
Adding 
both sides.
∴
Answer:
520 loaves
Step-by-step explanation:
First, let's find how many white loaves he baked.
Let's make a proportion.
white loaves/brown loaves= white loaves/brown loaves
He baked 3 white loaves for every 2 brown loaves. He baked x white loaves for 208 brown loaves.
3/2=x/208
Now, we have to solve for x. To do this, we have to get x by itself. x is being divided by 208. To reverse this, multiply both sides by 208
208*3/2=x/208*208
208*3/2=x
312=x
He baked 312 white loaves.
Now, we have to find the total number of loaves he baked.
To do this, add the brown loaves and the white loaves.
brown loaves+white loaves
He baked 208 brown loaves and 312 white loaves
208+312
520
He baked 520 loaves in total
