what is the midpoint of (4,5) and (9,17)
Answers
Answer:
Step-by-step explanation:
Midpoint formula: ( (x1+x2)/2, (y1+y2)/2)
where (x1, y1) and (x2, y2) are our points
Let (x1, y1) = (4, 5)
and (x2, y2) = (9, 17)
x1 = 4
x2 = 9
y1 = 5
y2 = 17
Then ( (4+9)/2, (5+17)/2 ) = (13/2, 22/2) = (13/2, 11)

Pick any two points and calculate the difference in their y-values and divide that by the difference in their x-values.
Notice that all y-values are the same, so your “change in y” or your “rise” is always 0.
0/anything = 0 (as long as the denominator isn’t 0)
So, your slope here is 0.

The summary are:
Steve bought the novel at $22.50 (including the discount)The discount given by the seller of the novel is 10%So, the original price will be computed as follows:
= $22.50 / (1 - 10%)
= $22.50 / 0.90
= $25
Therefore, the original price of the novel is $25.

Factor completely x3 + 5x2 − 3x − 15.
(x − 5)(x2 − 3)
(x + 5)(x2 + 3)
(x − 5)(x2 + 3)
(x + 5)(x2 − 3)
Answers
Answer:
(x + 5) (x^2 -3)
Step-by-step explanation:
[tex]x^{3} +5x^{2} - 3x - 15[/tex]
Do the grouping:
[tex]x^{3} +5x^{2} - 3x - 15 = (x^{3} +5x^{2}) + (-3x - 15)[/tex]
Then factor out [tex]x^{2}[/tex] in the first and −3 in the second group.
[tex]x^{2}(x+5) - 3(x+5)[/tex]
Factor out the common term x + 5 by using the distributive property.
Polynomial [tex]x^{2}-3[/tex] is not factored in since it does not have any rational roots, thus getting the following:
[tex](x+5)(x^{2} -3)[/tex]
Answer:
the fourth option (x+5)(x²-3)
Step-by-step explanation:
the "-15" tells us we need a 3 and a 5 with different signs.
that eliminates the first and the second options.
and the "5x²" tells us it has to be +5, as there is only one part in the whole multiplication that delivers a x² term (5×x²).
it is also confirmed for the same reasons by "-3x" that the other number has to be -3.

case high school sold 120 tickets to the school play and took in $195 from ticket sales. if student tickets were $1 and adult tickets were $2, how many of each kind did they sell?
Answers
Explanation:
Assume that all the ticket sold were adult ticket:
120 x 2$ = 240$
Then:
240$ - 195$ = 45$
Calculate the difference between student ticket and adult ticket:
2$ - 1$ = 1$
Find the student ticket:
45$/1$ = 45
45 ticket sold is the student ticket.
Find adult ticket sold:
120 - 45 = 75
75 ticket sold is the adult ticket.
Check:
(45 x 1) + (75 x 2) = 195
45 + 150 = 195
195 = 195

Which of the following points lies on the line defined by y = -3x – 7?
A. (2, -1)
B.(-2, 1)
C. (-2,-1)
D. (1,8)
E. (2, 1)
Answers
=========================================================
Explanation:
If we tried the x coordinate of choice A, then,
y = -3x-7
y = -3*2-7
y = -6-7
y = -13
This shows that the point (2,-13) is on the line and not (2,-1). This rules out choice A, and also choice E.
Let's try x = -2
y = -3x-7
y = -3*(-2)-7
y = 6-7
y = -1
This shows that (-2,-1) is a point on the line, and it points us to choice C being the final answer. This rules out choice B.
If we tried x = 1, then,
y = -3x-7
y = -3*1-7
y = -3-7
y = -10
Which shows that (1,-10) is a point on this line, which rules out choice D.
The visual summary is shown below as a graph. Only point C is on the red line.
