Sara goes to Fredonia University. She has $900 in her savings account. she needs to buy a small laptop computer before the next
podryga [215]
Given:
Saving amount = $900
Cost of Laptop = $600
Cost of food = $60 every 2 weeks

Let x be the number of times Sara can withdraw money for food. The inequality would be:

60x + 600 <u><</u> 900

60x + 600 <u><</u> 900 
 <u>       - 600      -600</u>
60x             <u><</u> 300
<u>÷ 60                 ÷60</u>
     x             <u>< </u>5

Sara can withdraw money 5 times or less for food.

Given the following linear function sketch the graph of the function and find the domain and range.
lisov135 [29]

Answer:

Domain of the given function is all real numbers and the range of the function all real numbers.

Step-by-step explanation:

The given function is

f(x)=-5x+4           .... (1)

The slope intercept form of a line function is

y=mx+b              .... (2)

Where, m is slope and b is y-intercept.

From (1) and (2), we get

m=-5,b=4

It means the slope of the line is -5 and y-intercept is 4.

Draw a line with slope -5 and y-intercept 4 on a coordinate plane as show below.

Domain is the set of inputs and range is the set of outputs.

The function is defined for all values of x. So, the domain of the function is all real numbers.

Domain=\{x|x\in R\}

The value of function can be any real number. So, the range of the function is all real numbers.

Range=\{y|y\in R\}

Therefore, the domain of the given function is all real numbers and the range of the function all real numbers.

Solve for X. Type in your numerical answer only, do not type the degree symbol.
Alja [10]

Answer:

x = 4

Step-by-step explanation:

Due to the Consecutive Interior Angles rule, c + e = 180. So, 20x + 5 + 24x - 1 = 180.

If you solve, you will get x = 4

Work:

20x + 5 + 24x - 1 = 180 [Add like terms]

44x + 4 = 180 [Isolate the variable]

44x = 176 [Solve]

x = 4
