Every autumn, the North American Monarch
Stolb23 [73]

Part A

The equation is d = 50t

This is because the slope of 50 represents how many miles per day the butterflies cover (on average). The y intercept is 0 to indicate that 0 miles have been traveled initially.

You can think of this as the equation y = 50x

If t = 1, then d = 50t = 50*1 = 50 miles have been covered

If t = 2, then d = 50t = 50*2 = 100 miles have been covered

And so on.

==========================================================

Part B

You'll have these values in the bottom row (in the order presented): 50, 100, 150, 200, 250

You can plug in the values t = 1, t = 2, t = 3, t = 4 and t = 5 into d = 50t to find those answers in bold.

Or you could add on 50 each time to generate each new value. We start at 50 since t = 1 corresponds to d = 50.

==========================================================

Part C

You can keep the pattern of 50,100,150, ... going until you reach 2500. Then note the t value that pairs with d = 2500

In my opinion, that's the slower method.

The quicker method is to plug d = 2500 into the equation for part A, and then solve for t.

d = 50t

2500 = 50t

50t = 2500

50t/50 = 2500/50 ....... divide both sides by 50

t = 50

It will take 50 days for the average distance traveled to be 2500 miles.

Vinvika [58]

Answer:

2 shirts and 14 pants

why it is awnser

it is that because if u do 15×16 u get 240 and if u subtract 10 twice from that u get 220 so

subtract 16 from 2 and that gives u how many pants she bought and the 2 represents the shirts

W(x)=x+4; find w(xt4)
shusha [124]

Answer:  W(x + 4) = x + 8

<u>Step-by-step explanation:</u>

I am assuming the "t" is supposed to be an addition sign "+"

w(x + 4) means to replace all of the x's in the given function with x + 4

W(x) = x + 4

W(x + 4) = (x + 4) + 4

             = x + 8
