Answer:
see below
Step-by-step explanation:
The transformation ...
g(x) = <em>a</em>·f(x -h) +k
represents ...
stretch if <em>a</em> > 1, compression if <em>a</em> < 1
if <em>a</em> < 0, there is a reflection across the x-axis
__
translation <em>right</em> by h units; <em>left</em> if -h is positive
translation <em>up</em> by k units; <em>down</em> if k is negative
_____
It's all about matching patterns.
Answer: 64 students
Step-by-step explanation:
What you already know : Total students in English class= 100
Nine twenty-fifths of the class did not like the book.
Therefore, the number of students like the book =Total students- students did not like the book
=100-36=64 students.
◆ Define the variables:
Let the calorie content of Candy A = a
and the calorie content of Candy B = b
◆ Form the equations:
One bar of candy A and two bars of candy B have 774 calories. Thus:
a + 2b = 774
Two bars of candy A and one bar of candy B contains 786 calories
2a + b = 786
◆ Solve the equations:
From first equation,
a + 2b = 774
=> a = 774 - 2b
Put a in second equation
2×(774-2b) + b = 786
=> 2×774 - 2×2b + b = 786
=> 1548 - 4b + b = 786
=> -3b = 786 - 1548
=> -3b = -762
=> b = -762/(-3) = 254 calorie
◆ Find caloric content:
Caloric content of candy B = 254 calorie
Caloric content of candy A = a = 774 - 2b = 774 - 2×254 = 774 - 508 = 266 calorie
(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56
