Answer:

Train A = 320 tons. Train B = 95 tons.

Step-by-step explanation:

Given:

Two trains,Train A and Train B, weigh a total of 415 tons.

Train A is heavier than Train B.

The difference of their weights is 225 tons.

Question asked:

What is the weight of each train?

Solution:

<u>As given that Train A is heavier than Train B and their weight's difference is 225 tons:-</u>

Let weight of Train B = x tons

Then weight of Train A = x+225 tons

<u>Combined weight of both train is 415 tons</u>

Weight of Train A + Weight of Train B = 415 tons

x+225+x=415\\\\ 2x+225=415\\

Subtracting both sides by 225

2x=190

Dividing both sides by 2

x=95

<u>Substituting the value:- </u>

Weight of Train B = x = 95 tons

Then weight of Train A = x+225 = 95 + 225 = 320 tons

Therefore, weight of Train A is 320 tons and weight of Train B is 95 tons.

Write a function that represents the relationship between X and y shown in the graph below

<h3>Answer:  y = 3x-10</h3>

==============================================================

Explanation:

Select any two points from the diagonal line. I'll pick (0,-10) and (2,-4).

Use these points in the slope formula

m = (y2 - y1)/(x2 - x1)

m = (-4 - (-10))/(2 - 0)

m = (-4 + 10)/(2 - 0)

m = 6/2

m = 3

The slope is 3.

The y intercept is b = -10 since this is the location where the diagonal line crosses the vertical y axis.

The values m = 3 and b = -10 have us go from y = mx+b to y = 3x-10

What value is added to both sides of the equation x2 - 8x = -10 in order to solve by completing the square?
IgorLugansk [536]
X² - 8x = -10

to have a complete square, we must have this format:

a² + 2ab + b²

a² = x²
2ab = -8x ⇒ 2(x)(-4)
b² = -4² = 16

x² - 8x + 16 = -10 + 16
x² - 8x + 16 = +6
(x-4)² - 6 = 0

Both sides must have an additional value of 16.

State the value of the discriminant. Then determine the number of real roots of the equation. n(7n + 8) = –10
Viktor [21]

Answer:

  a.  -216, 0 real roots

Step-by-step explanation:

The discriminant of ...

  ax² + bx + c = 0

is ...

  d = b² -4ac

When we put your equation into the standard form shown above, we get ...

  7n² +8n +10 = 0

Then we can identify a=7, b=8, c=10. The discriminant is then ...

  d = 8² - 4·7·10 = 64 -280 = -216

___

The interpretation of the discriminant is ...

  • < 0; no real roots (2 complex roots)
  • = 0; one real root (multiplicity 2)
  • > 0; 2 real roots

Your discriminant is -216, so there are 0 real roots.
