Masja [62]3 years ago

Answer:

100= 4 + 3 (100-1)

4+3 (99)

4 + 297 is 301

Step-by-step explanation:

The first row starts with 4 toothpicks, and they increase by +3 in each row.  The first tree is already accounted for which makes the 4 + 3, and why I have 100-1.  The teacher said the answer was correct but I doubted the equation.  Can you tell me if this is correct?

BRAINLIEST FOR AN ACTUAL ANSWER
Andreyy89

Answer:

The correct pair of functions is the third one:  h(x)=(x−24)^2 and g(x)=x2

Step-by-step explanation:

Example:  If we have q(x) = x^2 and its graph, moving the vertex of this graph 24 units to the right results in r(x) = (x - 24)^2.

The correct pair of functions is the third one:  h(x)=(x−24)^2 and g(x)=x2

Note:  the fourth pair is incorrect, because the " + " sign moves the graph of x^2 24 units to the left.

A chef got 7 bags of onions. The red onions came in bags of 8 and the yellow onions came in bags of 3. If the chef got a total o
frutty [35]

Answer:

\#\text{ of 8-onion bags: }4,\\\#\text{ of 3-onion bags: }3

Step-by-step explanation:

Let a be the number of bags with 8 onions and let b be the number of bags with 3 onions. We have the following system of equations:

\begin{cases}a+b=7,\\8a+3b=41\end{cases}

Subtracting b from both sides of the first equation, we get a=7-b. Substitute this into the second equation:

8(7-b)+3b=41,\\56-8b+3b=41,\\56-5b=41,\\-5b=-15,\\b=\boxed{3}

Therefore, the number of 8-onion bags is:

a=7-b,\\a=7-3,\\a=\boxed{4}

Thus, the chef got 4 8-onion bags and 3 3-onion bags.

a glacier receded 4 feet a day for a period of 25 days. how much shorter was the glacier at the end of the period.
dangina [55]

Alright, lets get started.

In the question given that glacier receded 4 feet a day for a period of 25 days.

Which shows in 1 day, it recedes = 4 feet

means in 1 day, the height of the glacier gets shorter = 4 feet

So, in 25 days, the height of the glacier gets shorter = 4 * 25

So, in 25 days, the height of the glacier gets shorter = 100 feet

It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer

Hope it will help :)
