I'm sending you two screenshots of the explanation I hope this helps.
Pls see answer below.
Step-by-step explanation:
In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.
Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.
Hope this helped.
Answer:
See below ~
Step-by-step explanation:
<u>Question 1</u>
⇒ -7x - (8x + 16) = -1
⇒ -7x - 8x - 16 = -1
⇒ -15x = 15
⇒ x = -1
⇒ y = 8(-1) + 16 = 8
⇒ Solution = <u>(-1, 8)</u>
<u></u>
<u>Question 2</u>
⇒ 3x + 4(-3x - 18) = 0
⇒ 3x - 12x - 72 = 0
⇒ -9x = 72
⇒ x = -8
⇒ y = -3(-8) - 18 = 6
⇒ Solution = <u>(-8, 6)</u>
<u>Question 3</u> (not clear)
<u>Question 4</u>
⇒ -8x - 7(6x) = 0
⇒ -8x - 42x = 0
⇒ -50x = 0
⇒ x = 0
⇒ y = 6(0) = 0
⇒ Solution = <u>(0, 0)</u>
<u>Question 8</u>
- 2x - 6y = -14
- y = -5x - 19
⇒ 2x - 6(-5x - 19) = -14
⇒ 2x + 30x + 114 = -14
⇒ 32x = -128
⇒ x = -4
⇒ y = -5(-4) - 19 = 1
⇒ Solution = <u>(-4, 1)</u>
Answer:
sin25 = cos65
Step-by-step explanation:
The unit rate is 9 miles per hour.
In order to find how much its unit rate will be you need to use this expression below.
<em>n = number of hours</em>
<em>m = number of miles </em>
m divided by n or <em>m/n</em>
In order to find how much does he travel in given hours see this below.
<em>n = number of hours</em>
<em>m = number of miles for 1 hour</em>
<em>nm or n * m</em>
