Answer:
i think it is 3
Step-by-step explanation:
i drawed a circle and put it into sections
then i saw that to get the 40 degree angle i have to divide it for times to make 8 parts
then i did 12 divided by 4 because divide the circle four time
when i did 12/4 i got 3
and if i am correct
thats the answer
Step-by-step explanation:
<em>=>(b*-b²)+(b*4b)-(b*3b)-(2*-b²)+(2*4b)-(2*3b)</em>
<em>=</em><em>></em><em>-b³</em><em>+</em><em>4</em><em>b</em><em>²</em><em>-</em><em>3</em><em>b</em><em>²</em><em>-</em><em>2</em><em>b</em><em>²</em><em>+</em><em>8</em><em>b</em><em>-</em><em>6</em><em>b</em>
<em>=</em><em>></em><em>-b</em><em>³</em><em>+</em><em>b²</em><em>-</em><em>2</em><em>b</em><em>²</em><em>+</em><em>2</em><em>b</em>
<em>=</em><em>></em><em>-b³</em><em>-</em><em>b²</em><em>+</em><em>2</em><em>b</em>
The slope is:
8
--------
5
The y-intercept is
-3
Please let me know if im wrong, but if im right I want brainliest, PLEASE!!!
First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
