<u>Algebra I</u>
- Reading a coordinate plane
- Solving systems of equations by graphing
Step-by-step explanation:
If 2 lines are parallel, they will have no solution.
If 2 lines are the same, they will have infinite amount of solutions.
We see from the graph that the 2 lines intersect at one point, near x = 1.5.
∴ our systems has 1 solution.
Answer:
42ft
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
So that little triangle section:
1/2 * 2 * 3 = 1/2 * 6 = 3
Now we do the rectangle Section:
Area of a rectangle = length * width
So that rectangle is 3 * 7 = 21
If you eliminate those two shapes, you are left with a trapezoid.
Area of a trapezoid is 1/2 * (base 1 + base 2) * height
Base 1 is 3 which is the width of the rectangle.
Base 2 is the 6.
The height is the given 11 feet subtracted by the 7 feet from the length of the rectangle which is 4.
Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.
Now add all of your areas together;
21 + 3 + 18 = 24 + 18 = 42
I assume you mean -x^3 + 4x + 3
so what you need is 4x + 3 > x^3
the only whole number it could be is 2 because 2x2x2 +3 > 2x2x2
Answer:
16.285
Step-by-step explanation:
you multiply a and b then divide by two cuz its a triangle
then you multiply b by pi and divide by 2 cuz its a semi circle
