Step-by-step explanation:
If in any set, you can find 2 or more points that lie on the same vertical,
then it is NOT a function, that is, the same value of x yields 2 or more different
values of y, you don't have a function.
e.g. D is definitely not a function. You have (-2,4) and (-2,-4) , the same x of -2 giving you a y value of 4 and -4.
Minimal grade to barely pass would be a C, but you should review and go for at least a B or B+ if you want to pass with a C in the class as a whole.
To vertically strech or shrink a function, multily the whole function by the factor taht you want to strech or shrink it by
to horizontally strech or shrink a function, multiply every x by the factor you want to strech or shrink it by
shrinks mean multiplying by a value greater than -1 and less than 1
stetch means multiply by a value greater than 1 or less than -1
first one
horizontal shrink
muliply every x by a fraction
so that is A
2nd one
vertical strech
multiply whole function by a value greater than 1 or less than -1
D is the answer
3rd one
horizontal strech
multiply every x by a value greater than 1 or less than -1
C is the answer
4th one
vertical shrink
multiply whole function by a value greater than -1 and less than 1
B is the answer
Answer:
Yes i
Step-by-step explanation:
A supplementary angle can be two angles that sum up to 180 if you want you can have 2 angles that are 90 degrees that add up to 180 so therefore that would make a right angle.
If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...
30% * x = 120
.30x = 120
x = 120/.30
x = 400
The original cost was $400
