The value of x in terms of b is x = . Therefore the value of x when b = 3 is x = = -1.
We can find both answers by rearranging the equation to get "x =", and then substituting in 3 for b:
-2(bx - 5) = 16
-2bx + 10 = 16
- 10
-2bx = 6
÷ -2
bx = -3
÷ b
x = -3/b, which is the answer to the first part.
To get the second answer, we just substitute b = 3 into this equation and we get:
x = -3/b = -3/3 = -1
I hope this helps!
X+2y=16
Subtract x from both sides
2y= -x+16
Divide both sides by 2
Y=-1/2x+8
Slope is -1/2 or - .5
Sure hope this helps and pls mark me brainiest
Answer:
9
Step-by-step explanation:
Because the Y's cancel out you add the absolute value of negative 5 and 4.
Answer:
8 inches of wire for 24 cents
Step-by-step explanation:
Simplify. Find the amount it costs for 1 inch of wire. Divide 45 with 15:
45/15 = 3
1 inch of wire costs 3 cents.
Now, solve for the the amount of wire (x) you can get for 24 cents
(1/3)(8/8) = (x/24)
1 x 8 = 8
3 x 8 = 24
x = 8
8 inches of wire for 24 cents
