Answer:
A = 12/5 units
Step-by-step explanation:
USING ALGEBRA:
We can find the intersection point between these two lines;
y = 3x - 6
y = -2x + 8
Set these two equations equal to each other.
3x - 6 = -2x + 8
Add 2x to both sides of the equation.
5x - 6 = 8
Add 6 to both sides of the equation.
5x = 14
Divide both sides of the equation by 5.
x = 14/5
Find the y-value where these points intersect by plugging this x-value back into either equation.
y = 3(14/5) - 6
Multiply and simplify.
y = 42/5 - 6
Multiply 6 by (5/5) to get common denominators.
y = 42/5 - 30/5
Subtract and simplify.
y = 12/5
These two lines intersect at the point 12/5. This is the height of the triangle formed by these two lines and the x-axis.
Now let's find the roots of these equations (where they touch the x-axis) so we can determine the base of the triangle.
Set both equations equal to 0.
(I) 0 = 3x - 6
Add 6 both sides of the equation.
6 = 3x
Divide both sides of the equation by 3.
x = 2
Set the second equation equal to 0.
(II) 0 = -2x + 8
Add 2x to both sides of the equation.
2x = 8
Divide both sides of the equation by 2.
x = 4
The base of the triangle is from (2,0) to (4,0), making it a length of 2 units.
The height of the triangle is 12/5 units.
Formula for the Area of a Triangle:
A = 1/2bh
Substitute 2 for b and 14/5 for h.
A = (1/2) · (2) · (12/5)
Multiply and simplify.
A = 12/5
The area of the region bounded by the lines y = 3x - 6 and y = -2x + 8 between the x-axis is 12/5 units.

What is the perimeter of the figure on the coordinate plane below?
Answer:
26 units
Step-by-step explanation:
im not sure if this will help but i counted the spaces and added the halves
The perimeter of the given figure on the coordinate plane is 56 units.
What is perimeter?A perimeter is the closed path that encompasses surrounds, or outlines either a two dimensional shape or a one-dimensional length.
Now from given figure, the following length of the sides is given,
9 units
4 units
4 units
8 units
11 units
3 units
2 units
15 units
Now since we know that,
Perimeter = Sum of lengths of all the sides
⇒ Perimeter = 9+4+4+8+11+3+2+15
⇒ Perimeter = 56 units
Thus, the perimeter of the given figure on the coordinate plane is 56 units.

The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle

What is the value of x?
11 (9 - 2x) = -(12x + 11)
Answer:
x=11
Step-by-step explanation:
First Distribute 11 to 9 and -2x
Then distribute the negative to 12x and 11
Then calculate like terms
-22x + 12x = -11 -99 which comes out to -10x=-110
Then divide each side by -10
Your answer will then be x=11

may someone please help me understand something in class? its theoretical and experimental probability basically just probability in a whole and I can’t understand. I don’t need the definition I just want someone to make me understand in a simple way like a tutor, but anyways please help me understand this. Examples would work, anything. Just help me understand. Thanks anyways.
Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

What is the slope. Please answer, this is worth 20 points!
Answer:
2
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
The slope is equal to the rise/run of the line, or in other words, the number of units it travels up over the number of units it travels right. We can see on the graph that for every time it travels right 1 unit it travels up 2 units, so the rise/run is 2/1. 2/1 is equal to 2, so therefore, the slope of the line is 2.

The solution is 16 green beads Julie will use when she uses 24 blue beads.
What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
given that,
Julie uses 4 green beads and 6 blue beads in each bracelet she makes.
Julie will use when she uses 24 blue beads
we have to find the total number of green beads Julie will use when she uses 24 blue beads
so, we have,
4 green beads and 6 blue beads in each bracelet
i.e. green beads : blue beads = 4 : 6
now. let, x green beads Julie will use when she uses 24 blue beads
i.e. green beads : blue beads = x: 24
we get,
4 : 6 = x: 24
so. x = 4 * 24 / 6
24 divided by 6= 4
4x4=16
we get,
For every 6 blue beads Julie used she used 4 green and she made 4 brackets so times 4x4 getting you to 16
Hence. 16 green beads Julie will use when she uses 24 blue beads.
