Sal: 25 +5x = 240

Divide 5 from both sides so it would be 5+ x=240/5
Subtract 5 from both sides x=48-5
X= 43

Elena: 15 + 5x=300

Divide 5 from both sides so it would be 3 +x=300/5
Subtract 15 from both sides x=60-3
X=57

So Sal jogged for 43 minutes. While Elena jogged for 57 minutes

What is the slope of 7x+3y<-26

Answer:

-7/3.

Step-by-step explanation:

Convert to the form y < mx + c where m is the slope:

7x + 3y < -26 Subtract 7x from both sides:

3y < -7x - 26 Divide through by 3:

y < (-7/3)x - 26/3

So the slope is -7/3.

Find the area between y = 8 sin ( x ) y=8sin⁡(x) and y = 8 cos ( x ) y=8cos⁡(x) over the interval [ 0 , π ] . [0,π]. (Use decima

Answer:

0.416 au

Step-by-step explanation:

Let y1=8sin(x) and y2=8cos(x), we must find the area between y1 and y2

$\int\limits^\pi _0{(8cos(x)-8sin(x))} \, dx = 8\int\limits^\pi _0{(cos(x)-sin(x))} \, dx =\\8(sin(x)+cos(x)) evaluated(0-\pi )=\\8(sin(\pi )-sin(0))+8(cos(\pi )-cos(0))=\\8(0.054-0)+8(0.998-1)=8(0.054)+8(-0.002)=0.432-0.016=0.416$
