That's a piecewise defined function and based on its definition we got the answer D.
(By combining -4≤x<2 and 2≤x≤10)
D. - 4 ≤ x ≤ 10
yes.
25 percent discount means that the price of one watch is 45 dollars.
45 plus 45 is less than 100.
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.
6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
Answer: x = 15; y = 32; z = 2.5
see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.
=> this parallelogram is a square
=> the diagonal lines of the parallelogram are perpendicular to each other
=> m∠1 = 90°
⇔ 3y - 6 = 90
⇔ 3y = 96
⇔ y = 32
because this is a square
=> 3x = 18z = 45°
=> x = 15
z = 2.5
