Answer: 29x -15y
Step-by-step explanation:
9x + 5(4x -3y) First apply the distributive property
9x + 20x - 15y Now combine like terms
(9x + 20x) - 15y
29x -15y
Water boils at 100 degrees celsius or 212 degrees fahrenheit. Water freezes at 0 degrees celsius or 32 degrees fahrenheit. If the weather forecaster says it will be 25 degrees celsius today. write and solve a linear equation to find what fahrenheit temperature this is.
Answer:
given with two conditions: after 0 degrees Celsius, this is equal to 32 degrees Fahrenheit and after at 100 degrees Celsius, this is equal to 212 degrees Fahrenheit . We translate these into points, we have (0,32) and (100, 212). we get the slope of the points ((212-32)/100) or 9/5. we plug to the equation y-y1 = m (x-x1) where m is equal to 9/5. y-32 = 9/5 (x-0). Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.
hope this helps
The given temperature is required in Fahrenheit.
The required temperature is 77 degrees Fahrenheit.
Let the x axis denote Celsius
and y axis denote Fahrenheit
The ordered pairs are [tex](100,212)[/tex] and [tex](0,32)[/tex]
The equation of the line will be
[tex]y-212=\dfrac{32-212}{0-100}(x-100)\\\Rightarrow y-212=1.8(x-100)\\\Rightarrow y-212=1.8x-180\\\Rightarrow y=1.8x+32[/tex]
The temperature is 25 degrees Celsius so [tex]x=25[/tex]
[tex]y=1.8\times 25+32\\\Rightarrow y=77[/tex]
The required temperature is 77 degrees Fahrenheit.

Which term best describes the graph of y = x – 1?
increasing
decreasing
constant
positive
Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing
The standard equation of a line in slope-intercept form is expressed as:
y = mx + b
where:
m is the slope of the lineb is the y-intercept of the lineThe nature of the graph is determined by the slope value.
If the slope is positive, the graph is increasing while if the slope is negative, the graph is decreasing.
Given the function y = x - 1, compared with the general equation;
mx = 1x
m = 1
Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

Find the x-intercept of the graph of the equation =−.+y equals negative , 2.65 , x plus 25.
What does the x-intercept mean in terms of the situation?
Answer:
Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

5. One reason beth might not want to join is because she would be the oldest person in the club. according to the stem and leaf chart the oldest person currently in the class is 55 and the next few down are all in their 40s.
Step-by-step explanation:
question 3 is 25 because the median is the middle number, which in this case is 25. question 4 you got correct but there are multiple modes for this set of data being 22,31,46 because all of these numbers tie with 2 of them being repeated throughout the table. question 5 just shows that beth would be the oldest in the club by a marginal number too so that is why beth might not want to join the club.
