Answer:
The inequality that comes from this equation is -2 < x < 0
Step-by-step explanation:
In order to solve this equation, we need to start by solving for the absolute value portion of the equation.
-5l2x + 2l + 7 > -3
-5l2x + 2l > -10
l2x + 2l < 2
Now we need to split the equation into two different portions. One with the absolute value symbol taken away. Then we do it again with the symbol flipped and the answer negated.
2x + 2 < 2
2x < 0
x < 0
And the negated version.
2x + 2 > -2
2x > -4
x > -2
Answer:
B.
Step-by-step explanation:
The percent increase when 7200 increases by 1800 is 25 %
Show that the angles A and B are congruent
Answer:
Step-by-step explanation:
The diagram of the sled kite is attached below.
The central part of the kite is square.
We know by the property of a square that all its angles are congruent and equal to 90 degrees.
Therefore:
Angles A and B are congruent.
(x − 8)(y − 4) = 50, so y = 4 + 50
x−8
. Then
A(x) = x
4 + 50
x − 8
x > 8.
A
0
(x) = 4 −
400
(x − 8)2
, so A
0
(x) = 0 gives x = 18.
A
00(x) = 800
(x − 8)3
> 0
so the function is concave up, so x = 18 is the absolute minimum. When x = 18, y = 9.
A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes. ... In real life, a scale copy is often smaller than the original figure.
