We need to combine like terms, so 4x-3x, and 8y+2y. x+10y is it simplified

Answer:

x + 10y

Step-by-step explanation:

To simplify this question, we need to collect like terms. For terms to be considered like terms, they have to have identical variables with identical exponents. Coefficients may be different. So 4x and 3x are like terms. 8y and 2y are also like terms.

4x + 8y - 3x + 2y = x + 10y

What is the equation in point slope form for the line that is parallel to y=-8x-12 that contains the point (-3,3)
belka [17]

Answer:

The equation of a parallel line in point-slope form would be y - 3 = -8(x + 3)

Step-by-step explanation:

To find this, we must first note that the original slope is -8. Parallel lines have the same slope, so we know that the new line will also have the slope of -8.

Given this information, we can use the point and slope and put them into the base form of point-slope form.

y - y1 = m(x - x1)

y - 3 = -8(x - -3)

y - 3 = -8(x + 3)

Trains Two trains, Train A and Train B, weigh a total of 360 tons. Train A is heavier than Train B. The difference of their weig
Sergio [31]
Since both trains in total weigh 360 tons and train A weighs more than train be, it means that train B is the rest of the weight when you subtract train A from the total amount. Difference means subtraction so just solve this: 360-272 to get train B and you already know that train A is 272 tons. Please mark branliest!

Which of the following changes will always be true for an exothermic process?
Ivenika [448]
Given that I no not see any explanation in the previos answer, I think you can benefit of this.

Exothermic refers only to the fact that the reaction releases energy in the form of heat when occurs. So, the enthalpy is higher at start and lower and the end.

Seen in this way, you can deduct that the change in enthalpy is negative, which is what the third option says.
