This is true because the same thing will happen to both sides
<span>The equation of a line is normally of the form:
y = mx + b ;
where m = slope and b = y int.
m = 10-70/5+15
= -60/20
= -3
y = -3x + b
plug in any given point:
10 = -15 + b
b = 25
Therefore: y = -3x+25</span>
<u>Answer:</u>
BC = 18 cm
<u>Step-by-step explanation:</u>
As we can see from the diagram:
AB + BC + CD = AD
⇒ 10 cm + BC + 11 cm = 39 cm
⇒ BC + 21 cm = 39 cm
⇒ BC = 39 cm - 21 cm
⇒ BC = 18 cm
Answer:
Look at the photo
Step-by-step explanation:
I hope I solved it right. Once you get the main concept of it, it's pretty easy.
If you have any questions about the way I solved it, don't hesitate to ask
negative 5 x less than or equals minus 10
-5x<=-10
divide by -5 (this will flip the inequality)
x>=2
Solution: x>=2
