Answer:
y = -5
Step-by-step explanation:
To solve for a variable, take the following steps:
- Distribute by multiplying into each term in the parenthesis
- Combine like terms
- Move terms across the equal sign using inverse operations
2 - 4 (y + 4) = 2y + 16 Distribute
2 - 4y - 16 = 2y + 16 Combine 2-16
-14 - 4y = 2y + 16 Add 4y to both sides
-14 = 6y + 16 Subtract 16 to both sides
-30 = 6y Divide by 6
y = -5
C kinetic energy. As it loses potential energy, it gain kinetic energy
66 percent because when u have an fraction 2/3 is 66 so the answer is 66 percent
The multiplication of 3 and -4 on a number line is shown
<h3><u>Solution:</u></h3>
The number line representation is shown below
On number line the points are at equal distances
The multiplication of 3 with -4 can be understood in the following way:-
a × b , means a jumps b times
Eg :- 3 × -4 means 3 jumps -4 times
Which basically mean we are going to move 3 number per step , and we are going to do this 4 times and –ve sign indicates we will move in negative direction
Therefore,
So, when we move from 0 , when we take first step we reach -3 , in next step we reach -6 , in next we reach -9 and in the last step we reach -12
Which is the product 3 and -4 .i.e.
For the 180 turn multiply the x/y by -1
4,-3 = -4,3
for the 90 turn you switch the x and the y and multiply by -1
4,-3 = 3,-4
