Answer:
<h3>
EVEN</h3>
Step-by-step explanation:
the product of odd numbers is always odd
the product of even numbers is always even
the product of odd number and even one is always even
the <u>sum of two odd </u>numbers is always <u>even</u>
and the sum of two even numbers is always even
so if x is even number we have:
x²=x•x - even number
x⁴=x²•x² - even number
3x²=3•x² - even number
y = x⁴+3x² <u>- even number</u>
and if x is odd number we have:
x²=x•x - odd number
x⁴=x²•x² - odd number
3x²=3•x² - odd number
y = x⁴+3x² <u>- even number</u>
Whole package weighs 20pounds
1.65 = 5pounds
0.12 = extra pound
3.45 - 1.65 = 1.80 : 0.12 = 15pounds
Adding up 15pounds and the first 5 pounds equal 20 pounds
PEMDAS
Multiplication:
10* -4 / 3*9 = -40 / 27
Addition:
-40 / 27 + 7/6 find common denominator 108
-40*4 / 27*4 + 7*18 / 6*18
-160 / 108 + 126 / 108
-34 / 108
-17 / 54
Subtract:
-17 / 54 - 2/5 common denominator 270
17*5 / 54*5 - 2*54 / 5*54
-85 / 270 - 108 / 270
-193 / 270
-193/ 270 = -0.7148
-8 / 15 = -0.7148 :)
Answer:
Graph the parabola opening down,
Step-by-step explanation:
With the vertex at (1, 1),factor the quadratic as y < (less than or equal to) –1(x)(x – 2),find the roots of the parabola to be 0 and 2,graph the parabola with a solid boundary line,test a point that is not on the boundary,and shade inside the parabola.
