Answer: Dilation
Why: Well the shape changes size so that makes me thing that it would be a dilation
Answer:
-8
Step-by-step explanation:
well since the equation has the <em>same base</em> of 11, you can just solve for x as you normally would. so the question becomes:
4x+1 = 3x -7
<em>subtract one from both sides</em>
4x = 3x - 8
<em>subtract 3x from both sides</em>
x = - 8
Answer:
x = 3/4 and x = -4/5
Step-by-step explanation:
20x⁴ + x³ + 8x² + x − 12
Group:
(20x⁴ + 8x² − 12) + (x³ + x)
Factor:
4 (5x⁴ + 2x² − 3) + x (x² + 1)
4 (5x² − 3) (x² + 1) + x (x² + 1)
(x² + 1) (4 (5x² − 3) + x)
(x² + 1) (20x² + x − 12)
(x² + 1) (4x − 3) (5x + 4)
So the rational roots are x = 3/4 and x = -4/5.
$15 x 12 = $180

Part A:
C= a + bn
Make the two equations out of the words:
82 = a + b100 * 2.5 = 205 = a + b250
157 = a+ b250
Subtract the two,
205 = a + b250
- ( 157 = a + b250)
48 = a
Find b by substituting in a:
82 = a + b100
82 = 48 + b100
34 = b100
b = 0.34
Answer for part a: a = 48 , b = 0.34
Part B:
C = a +bn <- when n = 300 , put in a and b, then solve
C = 48 + 0.34(300)
C = 48 + 102
C = 150
