1) It says he pours an equal amount into the first 7 beakers after pouring 16mL into the 8th so 70/7 = 10mL per beaker for the first 7.

2) If students rotate through 3 activites, each for 8 minutes, 3*8 = 24 minutes total. If it starts at 11:15, 24 minutes after that would be 11:39 (this represents the time they stop). If lunch starts at 12, there will be 21 minutes between the end of gym activities and the beginning of lunch.

VashaNatasha [74]

Answer:

x=94

Answer:

Inverse of f exists.

Step-by-step explanation:

From the graph attached,

If we do the horizontal line test for the function graphed,

We find the function as one to one function.

In other words for every input value (x-value) there is a different output value.

Since, for one-to-one functions, inverse of the functions exist.

Therefore, the answer will be,

The inverse of 'f' exists.

Name the property or definition illustrated below
dimulka [17.4K]

Answer: Substitution

Step-by-step explanation:

GIVEN:

y=3x

2x+4y=12

Then, 2x+4(3x)=12

-----------------------------------------

Substitution: replacing one variable in terms of another variable.

As we can see from the given aspects, y=3x, and the conclusion expression has no y instead of 3x. This means it represented y in terms of x, which fits the definition of substitution that replaces one variable.

Hope this helps!! :)
