Answer:
13
Step-by-step explanation:
4+(-3)-2*(-6)
Let us start from the left
2*(-6)= 2 times 6 , where we will have a negative sign on the result as + when multiplied by - gives - (negative)
2*(-6)=-12
4+(-3)-2*(-6) = 4+(-3)-(-12)
Now we open the bracket from the left. It the sign outside the bracket is negative the sign in the bracket will be changed
Hence
4+(-3)-(-12)= 4-3+12
Now -3 +12 we find the difference as the signs are opposite and then place the sign with the larger number
Hence -3+12=9
4-3+12=4+9 = 13
Answer:
y=(3x/2)+3 and y=(-1x/2)-1
Step-by-step explanation:
So what I did was use rise/run to find the slope of the equation. Let's focus on the line going from the bottom left to the top right corner. For this line, I would start on (-2,0) which is one of the points plotted on your number line and count how much it is away from (0,3). You should get 3 units. After this, count how much it is to the right which is 2 units. Now, use rise/run to find the slope. 3/2, therefore the slope of the line is 3x/2. Now all we need is the y-int. For the Y int, all we have to do is see where the line touches the Y-axis which in this case is at (0,3). So your y-int would be 3. Now we can use this information to craft an equation in the form y=mx+b, m being the slope and b being the y int. We should get y=(3x/2)+3. Now repeat this with the other line to find the equation, but be careful!!! It has a negative slope.
Answer: The value of y is 3 units.
Step-by-step explanation:
Since we have given that
ABCD is a rectangle
So, their both diagonals are equal .
so, AC= BD
here,
So, According to question,
Hence, the value of y is 3 units.
Use the standard equation of a circle with center at (h,k) and radius r:
(x-2)^2 + (y+4) = 3^2
I have helped you several times already with this type of problem. I'd love to see you demonstrate your growing understanding through sharing some of your own work instead of just asking for answers.
Subtract 3x from both sides
-14=-2x
Divide both sides by -2
7=x
