Graph the absolute value using the vertex and a few selected points.
x: -2, -1, 0, 1, 2
y: 4, 2, 0, 2, 4
Hope this helps! :)
Step-by-step explanation:
4[5x-3x(2-2x)]
=4[5x-6x+6x^2]
=4[-x+6x^2]
=-4x+24x^2
Answer:
C. 10.8
Step-by-step explanation:
The shortest distance from a line to a point is along a path at right angles to the line. That is, the segment marked 4 is a perpendicular bisector of the segment marked 20. Together with the radius (r), it makes a right triangle with legs 4 and 10. The Pythagorean theorem tells us ...
r² = 4² + 10²
r = √(16 +100) ≈ 10.77033
The radius of the circle is about 10.8 inches.
To solve this problem, we can set two equations.
Let x be the cost of coffee and y be the cost of latte.
Two coffees and one latte: 2x + y = 10.50
y=10.50 - 2x ...(1)
Three coffees and two lattes: 3x + 2y = 17.00...(2)
Put (1) into (2), we have:
3x + 2(10.50-2x) = 17.00
3x + 2(10.50) - 2(2x) = 17.00
3x + 21 - 4x = 17
Put the unknown to one side:
3x -4x = 17 - 21
-x = -4
When there are negative numbers on both sides, we can take the negative signs away:
x= 4
Therefore, cost of one coffee is A. $4.00.
