Answer:
-3
Step-by-step explanation:
2x - 4y = 12
4y = 2x - 12
y = ½x - 3
Y intercept is -3
X intercept is 6
The first step I would take is
.. Multiply both sides of the equation by 1/4.
_____
You could start by adding 16 to both sides of the equation, to make the left side the square (2x +4)^2.
Line L's slope intercept form is
y = 4x + 7
It's point slope form is
y - 3 = 4 (x - -1)
You can check the point slope form and match it with the slope intercept form:
y - 3 = 4 (x - -1)
y - 3 = 4x + 4
y = 4x + 7
y = 4x + 7 = y = 4x + 7
Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has only 1 cube, then there are 48 layers.
1. You have that:
- The<span> lengths of the bases are (6x-1) units and 3 units.
- The midsegment has a length of (5x-3) units.
2. To solve this exercise, you must apply the formula for calculate the length of the midsegment of a trapezoid, which is shown below:
Midsegment=Base1+Base2/2
As you can see, the midsegment is half the sum of the bases of the trapezoid.
3. When you substitute the values, you obtain:
(5x-3)=[(6x-1)+3]/2
4. Now, you can solve the problem by clearing the "x":
</span>
(5x-3)=[(6x-1)+3]/2
2(5x-3)=6x-1+3
10x-6=6x+2
10x-6x=2+6
4x=8
x=8/4
x=2
