|2x-3|=2x-3 ;x≥ 3/2
|2x-3|=-2x+3;x≤3/2
Answer:
1/12
Step-by-step explanation:
blue = (3/8)collection
blue&pocket = (2/9)blue = (2/9)(3/8)collection
blue&pocket = (6/72)collection = (1/12)collection
1/12 of Noah's collection is blue and has a pocket.
Answer: If a quadrilateral is a square, then it is a rectangle. (choice D.)
Step-by-step explanation:
The Law of Syllogism states that if the following two statements are true: If p , then q . If q , then r . Then we can derive a third true statement: If p , then r .
We can apply this rule in the conditional statements:
<em>If a quadrilateral is a square, (p) then it has four right angles. (q)</em>
<em>If a quadrilateral has four right angles, (q) then it is a rectangle. (r)</em>
Therefore:
<em>If a quadrilateral is a square, (p) then it is a rectangle. (r)</em>

Solution by completing the square.
-5x^2+20x-17
=-5(x^2-4x)-17
=(-5(x-2)^2+20) -17
=-5(x-2)^2+3
So a=-5, d=-2, e=+3
a+d+e=-5-2+3=-4
Answer: y=5, x=4
Step-by-step explanation:
3y= 15 divide both sides by 3
Y= 5
4x = x+12 subtract x from both sides.
3x = 12 divide both sides by 3
X= 4
