at bike shop x it costs $2.75 per hour plus a $3.00 deposit to rent a bike. at bike shop z it costs $1.75 per hour plus a $7.00 deposit to rent a bike.
a.) write the system of equations that could be used to find c, the total cost for renting a bike for n hours at each shop.
b.) graph the system of equations.
c.) when would it cost less to rent a bike from bike shop x? explain.
Answers
Answer:
Multiply the rate per hour by the number of hours (n) and add the deposit.
A)
Bike shop x: c = 2.75n + 3.00
Bike shop z: c = 1.75n + 7.00
B) to find when they will cost the same set the equations equal to each other and solve for n:
2.75n + 3.00 = 1.75n + 7.00
Subtract 3 from each side:
2.75n = 1.75n + 4.00
Subtract 1.75n from both sides:
1.00n = 4.00
Divide both sides by 1:
n = 4 hours

Teresa tried to find the solution to a system of equations with substitution but made an error in the process. After looking closely at Teresa's work, choose the answer that best describes the mistake she made.
A. Teresa made an error in one of her first steps when she added 2x to both sides (she should have subtracted 2x from both sides).
B. Teresa should not have subtracted 1 from both sides of the equation when trying to find x, she should have added 1 to both sides.
C. During the last step in solving for x, Teresa should have divided both sides by -4 (not divided both sides by 5). X should equal -5/4.
D. When substituting the value for x into one of the equations, Teresa should not have multiplied the fraction by 3. She should have added 3 to the fractions.
Answers
Answer: The answer is A.
Step-by-step explanation: She should of subtracted 2x on both sides, not add.

Step-by-step explanation:
1. we need to find the volume of one side, or shape, so first we have to find the volume of the rectangular prism.
2. the formula for rectangular prism is Length*width* Height, the length is 6, the width is 6, and the height is four.
3. 6*6=36, and 36*4=144, so the volume of the rectangular prism is 144.
4. we need to find the volume of the pyramid, and the formula for that is l*W*H/3, so the volume of the pyramid is 96.
5. Now we have to add the volumes up together, 96+144=240, so the volume is 240m. Please vote the brainliest
Answer:
240 m³
Step-by-step explanation:
Step 1 ⇒ We do the simple part of the solid figure which is a rectangle part of the composite solid by multiplying length by width by height.
6×6×4= 144
Step 2 ⇒ Now we are doing the top part of the solid figure which is a pyramid by using the equation [tex]\frac{lenght*width*height}{3}[/tex].
6*6*8=288 then divide it by 3.
288/3=96.
Step 3 ⇒ Add 144 to 96 to get your final answer.
144+96= 240 m³

Answers
Each graph is the result of one transformation. 1 and 4 are Reflection. 2 , 3, and 5 are rotation and 6 is translation.
How reflection across axis works?When a graph is reflected along an axis, say x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.
Thus, if you're reflecting a point (x,y) along the x-axis, then its x abscissa will stay the same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you're reflecting a point (x,y) along the y axis, the resultant image of the point will be (-x,y)
1st one would be Reflection
2nd would be Rotation
3rd would be Rotation
4th would be Reflection
5th would be Rotation
6th on the bottom would be translation

Step-by-step explanation:
Add each linear equation:
Sum: 5x = -5
Divide each side by 5:
Quotient: x = -1.
Substitute x = -1 into the first equation:
4(-1) - y = 5
Solve:
-4 - y = 5
Add 4 to both sides of the equation:
-y = 9
y = -9.
Check with the second equation:

-8x - 8 is the only expression equivalent to 16x - 12 - 24x + 4
Step-by-step explanation:
The easiest way you can do this problem is by substituting any number for x, for all of the expressions. That way you can compare the expressions. Let's choose to use 1 for example. So, x = 1.
If x = 1, you plug 1 in for all the x's. So, 16x - 12 - 24x + 4 would look like
16(1) - 12 - 24(1) + 4 = -16. Now let's see if any of the other expressions would ALSO equal -16 if x = 1.
4 + 16(1) - 12(1 + 2(1)) = 6
40(1) - 16 = 24
16(1) - 24(1) - 4 + 12 = 0
-8(1) - 8 = -16
Therefore, -8x - 8 is the only equivalent expression :)
