Solve the linear equation 2(3x + 2) = 2x – 1 + x. State the property that justifies your first step and why you
chose it.
Answer:
x = -5/3
Step-by-step explanation:
2(3x + 2) = 2x - 1 + x
2 × 3x + 2 × 2 = 2x + x - 1
6x + 4 = 3x - 1
3x = -5
x = -5/3

Over which interval(s) is g(x) = x2 + x - 12 positive?
A. -4 < x < 3
B. X <-4 and x > 3
C. X <-3 and x > 4
D. 3 < x < 4
Answer:
B. x < -4 and x > 3
Step-by-step explanation:
Factor and set = to 0
[tex]x^{2} + x - 12\\( x + 4)(x - 3)[/tex] = 0
x = - 4 or x = 3 I call these critical values
The two numbers would divide a number line into 3 intervals. Pick a value in one of the intervals and put it in the original expression. If it makes the function positive, then all the values in that interval make the function positive. If the value you picked makes the function negative, then the values in the other intervals will make the function negative. Let's pick the value of 0 and substitute it into the function
We get [tex]0^{2}[/tex] + 0 - 12 = -12 which is not positive. Therefore, all the values between -4 and 3 will make the function negative. So, the values less than -4 or greater than 3 will make the function positive. Therefore, B is the correct answer.
Another way to do this problem is to graph the function and see where the graph is above the x-axis. But, sometimes it is not easy to graph the function.

solve for a, geometry work
Answer:
a = 45 degrees
Step-by-step explanation:
Since both angles are a, they are equal to each other
Also, we know that the right angle means it measures 90 degrees
So, (180-90)/2 = a
a = 45 degrees

Which figures appear to be congruent?
An image of 5 triangles on a 14 by 12 grid is shown.Triangle 1 has a base that is 4 units long. The upper vertex is 4 units above the midpoint of the base. To the right, triangle 2 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned in the triangle at the lower left vertex. Below triangle 1, triangle 3 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 4 is toward the center of the grid. It has a horizontal leg that is 1 unit long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 5 is to the lower right. It has a horizontal leg that is 6 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the lower left vertex.

8000
*n in. One day, her sink clogged. She has to use one of two
3
cylindrical cups to scoop the water out of the sink. The sink is completely full,
when Akari begins scooping. Hint: you may need to find the volume for both.
(a) Cup A has a diameter of 4 in, and a height of 8 in. Find the Volume of Cup A.
(b) Determine how many cups of water must Akari scoop out of the sink with Cup A to
empty it? Round the number of scoops to the nearest whole number, and make
certain to show your work.
(c) Cup B has a diameter of 8 in, and a height of 8 in. Find the volume of Cup B.
(d) How many cups of water must she scoop out of the sink with Cup B to empty it?
Round the number of scoops to the nearest whole number, and make certain to

Find the solution(s) to the system of equations. Select all that apply.
y=x²-4
y=-x-2
The solution will be the intersection points thus options A (1,-3) and B (-2,0) will be correct.
What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
The solution will be the intersection points of both functions.
At the intersection point,
x² - 4 = -x - 2
x² + x - 2 = 0
x² + 2x - x - 2 = 0
x(x + 2) - (x + 2) = 0
(x - 1)(x + 2) = 0
x = 1,-2
At x = 1
y = -1 - 2 = -3 so first intersection is (1,-3)
At x = -2
y = -(-2) - 2 = 0 so second intersection is (-2,0)
Hence "The solution of the given system of equations is (1,-3) and (-2,0)".

The area of a parallelogram is 16 cm. One side Height is 4 cm. What is the length? options are:- 5 cm none of these 4cm 8cm
Answer: 4cm
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying the height by the length:
Area = Height * length
Assume the length is x, substituting values would make the formula:
16 = 4 * x
4x = 16
x = 16/4
x = 4 cm
