I hope this helps. u said 45 minutes, so i tried to some up with an answer. best of luck on ur work
Step-by-step explanation:
car a is 57 km in an hour, as 57t is equal to d. This, when d is 57 km will be 1 hr. So we are assuming that "t" is 1. Then d is 57. NOw lets check out car b. 140/2 is for 2 hrs, 210/3 for 3 hrs, and 280/4 for 4 hrs. This gives rate of 70 km in 1 hr.

You decided to get the Cinemark Movie Pass. It is a flat
fee of $8 and an additional $11.00 per ticket.
Enter the equation of the line in y= mx + b form.
Answer:
y = 11t + 8
Step-by-step explanation:
Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:
y = 11t + 8
Where "t" represents the amount of tickets bought.

y= x/4+7 (The x/4 is a fraction)
9514 1404 393
Answer:
noyesStep-by-step explanation:
In the equation ...
y = x² +3
the largest variable exponent is 2, which is not 1. The equation is not linear.
__
In the equation ...
y = (1/4)x +7
the largest variable exponent is 1, so the equation is linear.

An elevator started on the first floor, went up 18 floors, then came down 11 floors and went back up 16.
1 + 18 - 11 + 16
1 - 18 - 11 + 16
1 + 18 + 11 - 16
1 - 18 + 11 - 16
Answer:
1+18-11+16
Step-by-step explanation:
if the elevator went up it will be plus but if the elevator came down it will be minus and then you will get 1+18 because it went up and then it go down 11 floor and it will be 1+18-11 and then it went up again 16 floor so the last answer will be 1+18-11+16

PLZ HELP LAST QUESTION given the piecewise function given below select all statements that are true f(x)=-x+1,x<0 -2,x=0 x^2-1,x>0 All in brackets A.F(4)=7 Bf(-1)=2 c.F(-2)=0 d.F(1)=0
Answer:
Step-by-step explanation:
Given the function f(x)=-x+1,x<0 and f(x) = x^2-1,x>0
when x = 4
f(4) = -4+1
f(4) = -3
Also f(4) = 4^2 -1
f(4) = 8-1
f(4) = 7
when x = -1
f(-1) = -(-1)+1
f(-1) = 2
Also f(-1) = (-1)^2 -1
f(-1) = 1-1
f(-1) = 0
when x = -2
f(-2) = -(-2)+1
f(-2) = 3
Also f(-2) = (-2)^2 -1
f(-2) = 4-1
f(-2) = 3
when x = 1
f(1) = -1)+1
f(1) = -2
Also f(1) = (1)^2 -1
f(1) = 1-1
f(1) = 0
From the calculation above, the correct statements are
A. F(4)=7
B f(-1)=2
d. F(1)=0

A kayak is originally priced at $160. The online retailer gives a discount and the kayak is now priced at $88. Enter the percentage discount for the cost of the kayak.
Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.
Step-by-step explanation:
Answer:
45%
Step-by-step explanation:
O= 160
C=88
160-88=72
72 ?
160 100
72 times 100=7200
7200/160=45
(x+12)23-(2x-3)+16=12+5x-1
hmmmmmmmmm
Answer:
look at the attached picture
Answer:
X = -16.75
Step-by-step explanation:
Distribute.
(x + 12)23 = 23x + 276
12 + 5x -1 = 11 + 5x
Combine like terms.
23x - 2x - 5x = 16x
11 - (276 + 3+16 ) = -284
16x = -284
x = -17.75

The dimensions of the box below are reduced by half. What is the constant of proportionality between the volume of the new box and the volume of the original box? Alternative text A.1/2 B.1/4 C.1/8 D.1/16
Answer:
C. 1/8
Step-by-step explanation:
Dimensions of the Original Box:
Length = 40 inches
Width = 20 inches
Height = 8 inches
Volume of original box = L*W*H = 40*20*8 = 6,400 in³
Dimensions of the New Box (½ of the dimensions of the original box):
Length = ½*40 = 20 in
Width = ½*20 = 10 in
Height = ½*8 = 4 in
Volume of original box = L*W*H = 20*10*4 = 800 in³
Constant of proportionality between the volume of the new box and the volume of the original box = [tex] \frac{800}{6,400} = \frac{1}{8} [/tex]
Solve the system by substitution. Check your solution.
y = 0.8 x + 7.2.
20 x + 32 y = 48.
a. (8, -6)
b. (5, 11)
c. (-4, 4)
d. (-10, 2)
Answer:
c. (-4, 4)
Step-by-step explanation:
y = 0.8x + 7.2
20x + 32y = 48
20x + 32y = 48
20x + 32(0.8x + 7.2) = 48
20x + 25.6x + 230.4 = 48
45.6x + 230.4 = 48
45.6x = -182.4
x = -4
y = 0.8x + 7.2
y = 0.8(-4) + 7.2
y = -3.2 + 7.2
y = 4
