<em>Answer:</em>
<em>[-3,3]</em>
<em>Step-by-step explanation:</em>
<em>Write the problem as a mathematical expression.</em>
<em>4x^2+y^2=36</em>
<em>Subtract 4x^2 from both sides of the equation.</em>
<em>y^2=36-4x^2</em>
<em>Take the square root of both sides of the equation to eliminate the exponent on the left side.</em>
<em>y= + and - </em>
<em />
<em>The complete solution is the result of both the positive and negative portions of the solution.</em>
<em>y= </em>
<em />
<em />
<em />
<em>Set the radicand in </em>
<em> greater than or equal to 0 to find where the expression is defined.</em>
<em />
<em />
<em>So your answer would be [-3,3]</em>
To solve this question, simply find the percent of loaves of bread to total items, by taking the first loaves of bread and dividing it by the total bakery items. In this case would be, 15 loaves/25 • 100% = 60 %. Do the same calculation for the second loaves of bread. 25 loaves/37 • 100% = 67.567 %.
Now take the difference between the 2 percentages to find the percent increase of loaves of bread, which would be 7.567 %, about 7.6%. Or as a whole number 8%.
The percent increase of the loaves of bread has been 8%.
1. using 2 dots that are on the blue line (0,72) and (6,69)
find the slope:
slope = change in Y over change in x = 69 - 72 / 6-0 = -3 / 6 = -1/2
equation would be y = -1/2x + 72
2. y = -1/2x+72 = -1/2(30) +72 = -15 +72 = 57 beats per minute
3. replaced x in the equation with 30 to find the beats per minute for exercising 30 minutes
Answer:
3
Step-by-step explanation:
300 40
------ = -------
x 100
