Answer:
The cost per print expressed as a slope is 7.125
Step-by-step explanation:
To calculate the cost per print, let’s envision that we have a graphical representation of cost of posters against the number of posters
We have the cost on the y-axis and the number of posters on the x axis
With the information given in the question, we shall be having two data points
Point 1 = (32,126)
point 2 = (48,240)
Now to find the slope of the line which is cost per print, we make use of both points in the slope equation.
Mathematically, slope m will be
m = y2-y1/x2-x1
Thus, we have;
m = (240-126)/(48-32)
m = 114/16
m = 7.125
The cost per print expressed as a slope is 7.125

I don't understand the part "the 5/8 the 8is7" ?????????????
Step-by-step explanation:
<span>The correct answer is n</span>²<span>+3.
Explanation<span>:
We find the first differences between terms:
7-4=3; 12-7=5; 19-12=7; 28-19=9.
Since these are different, this is not linear.
We now find the second differences:
5-3=2; 7-5=2; 9-7=2.
Since these are the same, this sequence is quadratic.
We use (1/2a)n</span></span>²<span><span>, where a is the second difference:
(1/2*2)n</span></span>²<span><span>=1n</span></span>²<span><span>.
We now use the term number of each term for n:
4 is the 1st term; 1*1</span></span>²<span><span>=1.
7 is the 2nd term; 1*2</span></span>²<span><span>=4.
12 is the 3rd term; 1*3</span></span>²<span><span>=9.
19 is the 4th term; 1*4</span></span>²<span><span>=16.
28 is the 5th term: 1*5</span></span>²<span><span>=25.
Now we find the difference between the actual terms of the sequence and the numbers we just found:
4-1=3; 7-4=3; 12-9=3; 19-16=3; 28-25=3.
Since this is constant, the sequence is in the form (1/2a)n</span></span>²<span><span>+d;
in our case, 1n</span></span>²<span><span>+d, and since d=3, 1n</span></span>²<span><span>+3.</span></span>
