Answer:

-25

Step-by-step explanation:

You begin with -40, then decrease by 20 so your new value is -60, then increase by 35 so your final value is -25m... hope this helps (:

Answer:

the answer is she had $4.40 left.

Step-by-step explanation:

1) 40x1.50=60 2) 40x0.89= 35.6 3) 60+35.6= 95.6 4) 100- 95.6= $4.4 I hope this helps if not sorry. :)

Graph this parametric equation x = 2t y = t + 5, -2 ≤ t ≤ 3

UNO [17]

We are given the following data: x = 2t, y = t + 5, -2 ≤ t ≤ 3. The data is valid since there are three unknowns in this problem and that three equations would suffice to answer the problem.

We start with the given -2 ≤ t ≤ 3 then substitute y = t +5 by using the limits of the range:

at t = -2 ; y = -2 + 5 = 3
at t = 3, y = 3+5 = 8

for the second equation

at t = -2 ; x = 2*-2 =-4
at t=3; x = 2*3 = 6

we group the points based on their original corresponding t's

(3,-4) and (8,6) we just have to connect these points along with the internal points in between. The relationship should be linear.

If the instructions for a problem ask you to use the smallest possible domain to completely graph two periods of y = 5 + 3 cos 2

Finger [1]

The period of a sinusoid $\cos 2(x-c)$ is $\dfrac{2\pi}2=\pi$ , so any range such that $\mathrm{Xmax}-\mathrm{Xmin}=2\pi$ will give two complete periods.
