10x- (- 4 + 7x
answer if you can :)
Answers
Answer:
17x + 4
Step-by-step explanation:
The -(- would be turned into a positive due to the rule of two negatives makes a positive. You wouldn't add the 4 into either of the numbers with a variable, you would only add the 10x and 7x.
Answer:
3x+4
Step-by-step explanation:
Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.

8. Conduction. (Conduction is the transfer of heat that happens when particles collide with each other. It can happen in solids, liquids, and gases.)
Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same temperature. The hot burner is at a much higher temperature. In other words, the particles that make up the burner are moving at a greater average speed and therefore have greater thermal energy.
8b. Convection. During convection, however, the particles themselves move. This happens only in liquids and gases because the particles in solids are stuck in place and cannot move.

The whole pan is at the same temperature. The hot burner is at a much higher temperature, than the pan which causes the particles to move at a uneven speed.

Addition Sign RulesHere it is important to remember the rules for the addition of integers numbers:
+ + Add Final result (+) - Final result (+)
- - Add Final result (-) - Final result (-)
+ - Subtract - Final result (the sign of the integer having a greater value)
- + Subtract - Final result (the sign of the integer having a greater value)
Multiplication Sign RulesThe rules for multiplication of numbers are:
+ + or - -
The result presents a positive sign (+) because the signs are the same.
+ - or - +
The result presents a negative sign (-) because the signs are different.
For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

Look at this function: x y −12 −8 −8 −6 −4 −4 0 −2 Mina said that the function is linear. Jenna said that the function is nonlinear. Which of the following explains who is correct?
Mina, because for every 2-unit increase in x, there is an increase in y by 4
Mina, because for every 4-unit increase in x, there is an increase in y by 2
Jenna, because the point (0, −2) does not lie on the straight line that contains the other points
Jenna, because the point (−12, −8) does not lie on the straight line that contains the other points
Answers
C. Because (0,-2) has a y that is 4 greater but the x is 4 greater and everything else is x+4 y+2
The graph is nonlinear, the correct option is, "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".
What is linear and nonlinear function?A linear function gives a graph that is a straight line. On the contrary, a nonlinear function gives a graph that is not a line.
Given are coordinates, (x, y) = (−12, −8), (−8, −6), (−4, −4) and (0, −2)
The graph of these coordinates is not linear, because (0,-2) has a y that is 4 greater and the x is also 4 greater and other points are (x+4, y+2)
Hence, the correct option is "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".

A parallelogram ABCD is shown with height 12 units and base 8 units.
(1 point)
12 square units
24 square units
48 square units
96 square units
Answers
To figure out the area of a parallelogram, we need to identify its formula. However, I do know the formula, which is Area = Base x Height.
Area = Base x Height
Area = 8 x 12
= 96 cm squared
Therefore, the answer it 96 cm squared. By the way, I recommend that you review and comprehend the topic regarding area. Try memorizing all formulas for the shapes.
Rectangle & Square: Area = length x width
Triangle: Area = base x height
2
Trapezoid: Area = (Base 1 + Base 2) x h

Pararellogram: Area = base x height
Circle: Area = pi x r sqaured
Those are all the formulas I can recall; however, there might be more.
a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?
Answers
Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.
Creating a system of equations thus :
n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)Substitute for n and q
(q+3) + (q+6) + q = 36
3q + 9 = 36
3q = 36 - 9
q = 27 ÷ 3
q = 9 quarters
n = 9 + 3 = 12 nickels
d = 9 + 6 = 15 dimes
Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.
