Please provide the answer and the explanation pls, the explanation is what matters the most. Thank you and have a great day!
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(5x + 3) = b + 15x
a = (?)
b = 5ax + 3a - 15x (?)

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.

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.

Pls help me with this number riddle....
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.
