Amy didn't include the negative sign for the 20, so she got an imaginary number.
Richard made it imaginary when he didn't need to. (there isn't a negative sign underneath the radical).

How do you find the slope of a line.
Please help me with this homework
Answer:
C.
Step-by-step explanation:
Open circles mean < > not ≤ ≥. and the direction the line goes determines which symbol is used. the line goes up from -2 so its greater than -2 and down from 5 so less than 5
A Function is defined as K(x)= 2x^2 -5x +3.The value of K(-3) is
Given that [tex]K(x)= 2x^2 -5x +3[/tex] as a function, the value of K(-3) can be found by substituting x for -3 into the function which will give us: [tex]\mathbf{K(-3) = 36}[/tex]
Given the function, [tex]K(x)= 2x^2 -5x +3[/tex], to find the value of K(-3), substitute -3 for x into [tex]K(x)= 2x^2 -5x +3[/tex].
Thus, substitute:[tex]K(-3)= 2(-3)^2 -5(-3) +3\\\\K(-3) = 18 + 15 + 3\\\\\mathbf{K(-3) = 36}[/tex]
Therefore, given that [tex]K(x)= 2x^2 -5x +3[/tex] as a function, the value of K(-3) can be found by substituting x for -3 into the function which will give us: [tex]\mathbf{K(-3) = 36}[/tex]

Help please anyone!!!!!!
Answer:
[tex]\huge\boxed{D)\frac{3p}{p-3} }[/tex]
Step-by-step explanation:
The first thing that can help you here is factoring every term.
[tex]p^2-4p-12[/tex]
Factor.
[tex](p-6)(p+2)[/tex]
[tex]6p+12[/tex]
Factor.
[tex]6(p+2)[/tex]
18p
Factor, keeping in mind the denominator of the other term.
[tex]6(3p)[/tex]
[tex]p^2-9p+18[/tex]
Factor.
[tex](p-6)(p-3)[/tex]
Now you have simplified your original problem:
[tex]\frac{p^2-4p-12}{6p+12} *\frac{18p}{p^2-9p+18}[/tex]
into:
[tex]\frac{(p-6)(p+2)}{6(p+2)} *\frac{6(3p)}{(p-6)(p-3)}[/tex]
Now, after multiplying the numerator and denominator of the fractions:
[tex]\frac{(p-6)(p+2)(6)(3p)}{(6)(p+2)(p-6)(p-3)}[/tex]
Then, you can simplify the fraction by cancelling terms:
[tex]\frac{3p}{p-3}[/tex]

Answer:
i believe it is 16
Step-by-step explanation:
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 7,10,13,...
Find the 33rd term.
The 33rd term of the arithmetic sequence, 7,10,13.... is: 103
Recall:
An arithmetic sequence has a common difference, d, which is the difference between consecutive terms.nth term of an arithmetic sequence is found using: an = a + (n - 1)d, where, a is the first term and d is the common difference.The sequence, 7,10,13,... is an arithmetic sequence because:
13 - 10 = 10 - 7 = 3
Therefore, to find the 33rd term, substitute a = 7, n = 33, and d = 3 into an = a + (n - 1)d.
Thus:[tex]a_{33[/tex] = 7 + (33 - 1)3
[tex]a_{33[/tex] = 7 + (32)3
[tex]a_{33[/tex] = 103.

Answer:
B
Step-by-step explanation:
(5x - 2)² + 35x - 14 = - 12 ( factor out 7 from each term in 35x - 14 )
(5x - 2)² + 7(5x - 2) = - 12 ( add 12 to both sides )
(5x - 2)² + 7(5x - 2) + 12 = 0
Substitute m = 5x - 2 into the equation then in terms of m, the equation is
m² + 7m + 12 = 0 → B

Answer:
The perimeter of the Parallelogram is 20z + 16
Step-by-step explanation:
For a Parallelogram
Perimeter = sum of all sides
P = (7z + 3) + (7z + 3) + (3z + 5) + (3z + 5)
P = 7z + 7z + 3z + 3z + 3 + 3 + 5 + 5
P = 20z + 16
Thus, The perimeter of the Parallelogram is 20z + 16

does the point (5 6) satisfy the equation y = 2x - 7
Answer: No
Step-by-step explanation: To determine this, all we have to is plug our ordered pair into the equation for x and y.
Remeber that the first number is our x-coordinate and our second
number is our y-coordinate so we plug a 5 in for x and a 6 in for y.
So we have (6) = 2(5) + 7 or 6 = 10 + 7 or 6 = 17.
Since this is not a true statement, this point doesn’t satisfy the equation.
write the equation of the line from the given information. slope 1/2, through (4,-3)
Answer:
y+3 = 1/2 (x-4)
Step-by-step explanation:
We can write the equation in point slope form
y-y1 = m(x-x1)
The slope is m and the point is (x1,y1)
y - -3 = 1/2(x -4)
y+3 = 1/2 (x-4)
