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.

A horizontal slice through a three-dimensional solid produces the two-dimensional shape below. (The shape is a square)
Which one of the following solids produces this two-dimensional shape when sliced horizontally?
Is it A, B, C, or D????
Answer:
C
Step-by-step explanation: i am doing same thing you are doing rn
You can use the fact that a horizontal slice is like you're slicing the given shape parallel to ground.
The correct shape which will produce a square when sliced horizontally is ""D" figure which as 4 sides.
What is a square?A square is a closed figure formed by end to end joined equal length four line segments such that all the adjacent lines are perpendicular to each other.
A square has 4 sides.
What is horizontal slicing?Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.
When you slice an object horizontally, you cut it parallel to ground.
How to know which of the given solid will produce square?Since a square has 4 equal sides, all perpendicular to each other, we see that only 4th object has 4 sides.
Thus, the fourth solid, named D is the solid that can produce square when sliced horizontally.

Answer:
75
Step-by-step explanation:
Let's look at your problem shall we:
Odd number: It should end with the numbers 1,3,5,7, and 9.
The number is less than 100: It should be from the number 1-99
Sum of digits: 12
Multiple of 15: 15, 30, 45, 60, 75, and 90.
We can rule out 30, 60, and 90 because they are even.
1+5 = 6; 4+5=9; 7+5 = 12
You are left with 75.

Gabe goes to the mall. If d is the number of items he bought, the expression 16.62d gives the amount he spent in dollars at one store. Then he spent 26 dollars at another store. Find the expression which represents the amount he spent at the mall. Then estimate how much Gabe spent if he bought 7 items.
Answer:
1. 16.62d + 26 = m 2. $152.34
Step-by-step explanation:
For the first part of the question you put the unknown variable multiplied by 16.62. Then add 26 which equals an unknown variable. For the second part, I multiplied 16.62 by 7 and added 26.

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

Answer:
1. transversal: (of a line) intersecting a system of lines.
2. acute angle: Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees. Learn about angles types and see examples of each.
3. alternate extirior angles: When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.
4. congruent: in agreement or harmony.
5. congruent figures: Congruent figures are geometric figures that have the same shape and size. That is, if you can transform one figure into another figure by a sequence of translations , rotations , and/or reflections , then the two figures are congruent.
6. isosceles triangle: In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case
7. obtuse angle: An obtuse angle ...” ... An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees. So, an angle of 190 degrees would be reflex.
8. right angle: an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
9. remote interior angle: Remote interior angles are angles that don't share a vertex or corner of a triangle with the exterior angle. The measure of the exterior angle equals the sum of the two remote interior angles.
10. same-side interior angles:Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.
11. corresponding angles: When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
12. corresponding parts: corresponding parts. Sides or angles that occupy the same relative positions in similar polygons. congruent triangles. 2 triangles are congruent if and only if all pairs of corresponding sides and angles are congruent.
13. equilateral angle: In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
14. exterior angle: 1 : the angle between a side of a polygon and an extended adjacent side. 2 : an angle formed by a transversal as it cuts one of two lines and situated on the outside of the line.
15. scalene triangle: A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.
16. similar figures: Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .
17. striaght figures: A line that does not curve. In geometry a line is always straight (no curves).
18. theorem: a general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.
