Evaluate each expression for the given values of the variables. 1. 8z+3;7 z=8 2. 3(7+x^2); x=2 3. S-52+s^2,s=4,t=-1 4. X-y^3;x=-7, y=3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
