First take away fifty from both sides
25w = 350
Divide 25 from both sides
Answer is: w = 14


So, it will take Uma 14 weeks to save enough money to but the video game system.




Hope that helps!!!

What are integers?<br> Please give your best explanation and a simple example (worth 20 points)

<h3><u>Explanation</u></h3>
  • What is Integer?

Integer is a subset of Real Number. It can be broken into these following:

  1. Positive Integer
  2. Zero
  3. Negative Integer

Integer can be any whole numbers. Keep in mind that Integers cannot be fractions, decimal, approximate value, etc. Integers can only be something like 1,2,3,-1,-2,0.

<u>Integers</u><u> </u><u>are</u><u> </u><u>like</u><u> </u><u>Natural</u><u> </u><u>or</u><u> </u><u>Counting</u><u> </u><u>Numbers</u><u> </u><u>except</u><u> </u><u>they</u><u> </u><u>have</u><u> </u><u>0</u><u> </u><u>and</u><u> </u><u>negative</u><u> </u><u>numbers</u><u>.</u>

  • Positive Integer

Positive Integers are basically a natural or counting number. It starts from 1 to any positive countable infinity. Here is the example of positive integer: 1,2,3,4,5,6,7,...

  • Zero

Zero is just a number 0. It is between the negative and positive. 0 is neither positive or negative but it is categorized as Zero.

  • Negative Integers

Negative Integers are opposite of Positive Integers. The opposite of plus is minus and the opposite of minus is plus. Negative Integers are less than both 0 and Positive Integers. Here is the example: -1,-2,-3,-4,-5,...

How to find if it is a function or not:
Leto [7]

Answer: It is not a function.

Step-by-step explanation:

A function is something that "eats" an input and transforms it into an output.

We write them as y = f(x)

Where x is the input, and y is the output.

Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.

This means that, for example, if we have, for x = x1.

And a single

f(x1) = y1

f(x1) = y2

where y1 and y2 are different values.

Then this is not a function, because it is mapping the value x1 into two different outputs.

In this case, we would have:

f(Z) = A.

So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.

This means taht the set (Z, A) can not represent a function.

Type the correct answer in the box. Use numerals instead of words. Consider this expression. Vas – 7+ 161 When a = 2 and b = -4,
sp2606 [1]

<em>Correct Question:</em>

<em>Type the correct answer in the box. Use numerals instead of words. Consider this expression. </em>\sqrt{a^2} - 7 + |b|<em> </em><em> When a = 2 and b = -4, the value of the expression is​</em>

Answer:

\sqrt{a^2} - 7 + |b| = -1

Step-by-step explanation:

Given

a=2

b = -4

Required

Determine \sqrt{a^2} - 7 + |b|

To solve this, we simply substitute the values of a in the given expression

\sqrt{a^2} - 7 + |b|

\sqrt{a^2} - 7 + |b| = \sqrt{2^2} - 7 + |-4|

Express 2² as 4

\sqrt{a^2} - 7 + |b| = \sqrt{4} - 7 + |-4|

Express square root of 4 as 2

\sqrt{a^2} - 7 + |b| = 2 - 7 + |-4|

|-4| = 4

So, we have

\sqrt{a^2} - 7 + |b| = 2 - 7 + 4

\sqrt{a^2} - 7 + |b| = -1

<em>Hence, the result of the expression is -1</em>

I need help with this math question. Can you fill all the blanks please

Answer:

Δ ABC was dilated by a scale factor of 1/3, reflected across the y-axis

and moved through the translation (1 , -2)

Step-by-step explanation:

* Lets explain how to solve the problem

- The similar triangles have equal ratios between their

  corresponding side

- So lets find from the graph the corresponding sides and calculate the

  ratio, which is the scale factor of the dilation

- In Δ ABC :

∵ The length of the vertical line is y2 - y1

- Let A is (x1 , y1) and B is (x2 , y2)

∵ A = (-6 , 0) and B = (-6 , 3)

∴ AB = 3 - 0 = 3

- The corresponding side to AB is FE

∵ The length of the vertical line is y2 - y1

- Let F is (x1 , y1) , E is (x2 , y2)

∵ F = (3 , -2) and E = (3 , -1)

∵ FE = -1 - -2 = -1 + 2 = 1

∵ Δ ABC similar to Δ FED

∵ FE/AB = 1/3

∴ The scale factor of dilation is 1/3

* Δ ABC was dilated by a scale factor of 1/3

- From the graph Δ ABC in the second quadrant in which x-coordinates

 of any point are negative and Δ FED in the fourth quadrant in which

 x-coordinates of any point are positive

∵ The reflection of point (x , y) across the y-axis give image (-x , y)

* Δ ABC is reflected after dilation across the y-axis

- Lets find the images of the vertices of Δ ABC after dilation and

 reflection  and compare it with the vertices of Δ FED to find the

 translation

∵ A = (-6 , 0) , B = (-6 , 3) , C (-3 , 0)

∵ Their images after dilation are A' = (-2 , 0) , B' = (-2 , 1) , C' = (-1 , 0)

∴ Their image after reflection are A" = (2 , 0) , B" = (2 , 1) , C" = (1 , 0)

∵ The vertices of ΔFED are F = (3 , -2) , E = (3 , -1) , D = (2 , -2)

- Lets find the difference between the x-coordinates and the

 y- coordinates of the corresponding vertices

∵ 3 - 2 = 1 and -2 - 0 = -2

∴ The x-coordinates add by 1 and the y-coordinates add by -2

∴ Their moved 1 unit to the right and 2 units down

* The Δ ABC after dilation and reflection moved through the

  translation (1 , -2)
