Answer:
2. 325 minutes.
Step by step explanation:
We will substitute our given number of minutes in our both equation one by one to find the correct option.
1. Let us substitute m= 775 in both equations.
We can see that both plans have different costs , therefore, 1st option is incorrect.
2. Let us substitute m= 325 in both equations.
When Vanessa has used the phone for 325 minutes, the cost for Plan A and the cost for Plan B will both be $64.25.Therefore, 2nd option is correct choice.
3. Let us substitute m= 32.5 in both equations.
4. Let us substitute m= 764 in both equations.
Therefore, 4th option is incorrect.
Answer:
please mark brainliest ! It means that dilations map angles to angles, and the dilation preserves the measures of the angles. dilations. Dilations map lines to lines, rays to rays, and segments to segments.
You mean their sum is 12?
A) x + y = 12
B) x -y = 4 then we add both equations:
2x = 16
x = 8
y = 4
Answer:
1. y = 9280 - 20x
2. f(y) = 6.37y - 3
Step-by-step explanation:
1. The equation is given to be
Now, rearranging the function we can write
⇒ y = 9280 - 20x
Hence, this is the equation as a function of x. (Answer)
2. The given function is y - 6.37x = - 3
Therefore, we can write, y = 6.37x - 3
Hence, f(x) = 6.37x - 3
⇒ f(y) = 6.37y - 3.
Hence, option D is true. (Answer)
