Area as a function of length can be written as
f(l) = l^2
And volume of cube can be expressed as a function of side s as,
f(s) = s^3
Answer:
The value of x is 1 and y = -2
Step-by-step explanation:
y = 2x²- 3x - 1;
y = x - 3
2x²- 3x - 1 = x - 3
2x² - 3x - 1 - x + 3 = 0
2x² - 4x + 2 = 0
take 2 as common
2(x² - 2x + 1) = 0
x² - 2x + 1 = 0
x² - x - x + 1 = 0
x(x - 1) - 1(x - 1) = 0
(x - 1) (x - 1) = 0
x - 1 = 0 or x - 1 = 0
x = 1 or x = 1
Now,
y = x - 3
y = 1 - 3
y = - 2
Thus, The value of x is 1 and y is -2

Answer:
The Commutative Property
Step-by-step explanation:
<span>The volume of a rectangular prism is
V = l · w · h
V= 252 cm3
h= 3 cm
l=5+W
W=x then l=5+x
V=(5+x)*x*3=252
3x</span><span>^2+15x=252 cm3
</span><span>
the equation that models the volume of the tray in terms of its width, x, in centimeters.</span>
3x^2 +15x=252 cm3<span>
</span>
for width=7.5 cm
3x^2
+15x=3*(7.5) ^2+15*7.5= 281.25 cm3
<span>281.25>252 </span><span> </span>
<span>it is not possible that the width is 7.5 cms</span>
Answer:
Step-by-step explanation:
1. y= 1-x² is quadratic because has the variable x to the second power
y = -x² +1 has quadratic term -x², and constant term is 1
2. y= 3x-5 +4x²
a. quadratic term is 4x² because has the variable x to the second power
b. linear term is 3x because has the variable x to the power of one
c. constant term is -5 because the variable x to the power 0 so there is no x
