Answer:
Train A is 266 and Train B is 85
Step-by-step explanation:
If the difference is 181 tons, then subtract the difference to get double the weight of the lightest train.
351 - 181 = 170
170 ÷ 2 = 85
If B is the lightest, B is 85.
For A, either add the difference back or subtract 85 from 351.
85 + 181 = 351 - 85 = 266
Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer: x = 3 or x = -1
Answer:
Step-by-step explanation:
The first one is that it is 4 more every time.
the second one under the 5 put 290 because 116 divided by 2 is 58 and you times 58 by 5 which is 290
on top of 460, put 7 because you divide 460 by 58 which is 7
under the 8 put 464 because 8 x 58 is 464
It is a proportional relationship because it goes up every time.

Option: C is the correct answer.
The equation of the Blue graph is:
C.
<h2>
Step-by-step explanation:</h2>
We are given a graph of a parent function F(x) as:
We know that the function G(x) is nothing but a translation transformation of the parent function by some units to the left.
Also we know that the transformation k units to the left or right is denoted by:
F(x) → F(x+k)
if k>0 then the shift is k units to the left.
and if k<0 then the shift is k units to the right.
Here we have k= 3 and shift is to the left.
Hence, the equation of translated function is:
G(x)=F(x+3)
i.e.
b is the correct answer because it equals the amount of the proplem
