I think the answer is for
1 book (x = 1)
1150+25(1)= 1175
For 2 books (x - 2)
1150+25(2) = 1200
Next, to find the change in total cost, subtract these 2 answers:
1200 - 1175 = 25
what is the area of a rectangle whose length is (2x-1) cm and whose width is (X+2) cm?
help.
Answer:
2x^2 + 3x - 2
Step-by-step explanation:
=> area of rectangle = length*width
=> length = (2x -1)
=> width = (x + 2)
=> area = (2x - 1) (x + 2)
=> area= 2x(x + 2) - 1(x + 2)
=> area = 2x^2 + 4x - 1x - 2
=> area = 2x^2 + 3x - 2
hope it helps

Answer:
a) y = 2 x - 1
b) y = - x + 7
c) y = 7 x + 2
Step-by-step explanation:
Use a pair of (x1, y1) and (x2, y2) points to find the equation of the line for each tables:
a) (5, 9) and (10, 19)
slope: (y2 - y1) / (x2 - x1) = (19 - 9) / (10 - 5) = 10 / 5 = 2
Then y = 2 x + b
solve for b in: 9 = 2 (5) + b
b = 9 - 10 = -1
Then y = 2 x - 1
b) (2, 5) and (5, 2)
slope: (y2 - y1) / (x2 - x1) = (2 - 5) / (5 - 2) = -3 / 3 = -1
Then y = - x + b
solve for b in: 5 = - (2) + b
b = 5 + 2 = 7
Then y = - x + 7
c) (3, 23) and (6, 44)
slope: (y2 - y1) / (x2 - x1) = (44 - 23) / (6 - 3) = 21 / 3 = 7
Then y = 7 x + b
solve for b in: 23 = 7 (3) + b
b = 23 - 21 = 2
Then y = 7 x + 2

Last week, Juliet ran 22 kilometers. This week, she plans to run 2\frac{2}{5}2 5 2 times as far as last week. How many kilometers does Juliet plan to run this week?
Answer: 52.8 kilometers
Step-by-step explanation:
This week she plans to run 2²/₅ times as much as last week.
If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.
First convert the improper fraction to a proper one:
2²/₅ = 12/5
= 12/5 * 22
= 264/5
= 52.8 kilometers

Determine whether the following statement is true or false.
The graph of f(x) = (x + 2)2 + 4 has its vertex at (2,4).
Choose the correct answer below.
O True
0 False
Answer:
Step-by-step explanation:
No it doesn't. When you get stuck on a question like this one, you should go to Desmos and graph the equation. I've done that for you.
Correctly stated the equation should read f(x) = (x + 2)^2 + 4
As you can see from the graph the vertex is at -2,4. To find the x value of the vertex, create a small equation
x + 2 = 0
x = - 2
That will turn what is inside the brackets into 0. The value for x is always what will turn (x + a) to zero.

A train travels 1 kilometre in 1 minute 20 seconds. Picture of steam train Question prompt At this rate, how many kilometres will the train travel in 1 hour?
Answer:
45km
Step-by-step explanation:
Distance covered in 1min 20sec (80sec) = 1km
Distance covered in 1 min (60sec) = 1km/80sec
Distance covered in 1Hr (3600sec) = (1/80)*3600 = 45km.
For which value of theta is sine theta = negative 1?
A unit circle is shown. A radius with length 1 forms angle theta in the first quadrant.
StartFraction pi Over 2 EndFraction
Pi
StartFraction 3 pi Over 2 EndFraction
2 pi
Answer:
1) 270 degrees
2) pi/4 rad
Step-by-step explanation:
1.) For which value of theta is sine theta = negative 1?
Given
sintheta = -1
theta = arcsin(-1)
theta = -90degrees
Since sin is negative in the third and 4th quadrant
In the third quadrant, theta = 180 + 90 = 270degrees
In the fourth quadrant, theta = 360 - 90 = 270 degrees
Hence the required value of theta is 270degrees
2) Given the radius of the circle to be 1, the y axis value will also be 1 units
Opposite = 1
adjacent = 1
hyp = √1²+1²
hyp = √2
sin theta = opp/hyp
sin theta = 1/√2
theta = arccsin(1/√2)
theta = 45 degrees
Express in radians
45 degrees = pi/4 radians
Hence the required angle in the first quadrant is pi/4 rad
Answer:
3pi/2
Step-by-step explanation:
that is only one that makes sine negative. others make it 0 or positive
