Answer:
y= - 1/4x - 3
Step-by-step explanation:
Hey there!
You got the first part right where you added r to both sides. However, you need to make sure that you complete all actions on both sides, including canceling out parts of terms by division. The only thing you need to do is divide both sides by h instead of just the left. This will make your answer:
Hope this helped you out! :-)
Answer:
d.10cm,5cm,9cm
Step-by-step explanation:
In a triangle, the length of each side must be between the difference and the sum of the lengths of the other sides.
a. 1 + 1 = 2; 2 < 3 Answer: no
b. 2 + 3 = 5; 5 = 5 Answer: no
c. 10 - 3 = 7; 7 > 4 Answer: no
d. 10 + 5 > 9
5 + 9 > 10
10 + 9 > 5
10 - 5 < 9
10 - 9 < 5
9 - 5 <10
Answer: yes
If the perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.
<h3>Parimeter</h3>
Let a = longest
Let b= shortest
Let c= third side
a = 2c
a = (b+ c) - 3
a + 3 = b + c
Using three variables to solve the expression for perimeter
Perimeter= 19 cm
a+ b + c = 19
a + (a + 3) = 19
2a + 3 = 19
2a= 16
Divide both side by 2a
a=16/2
a = 8
a = 2c
8 = 2c
c=8/2
c = 4
a + b + c= 19
8 + b + 4 = 19
12 + b = 19
b=19-12
b = 7
Hence,
a = 8, b = 7, c = 4
Therefore If the perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.
The complete question is:
Perimeter of triangle is 19cm. If the length of the longest side is twice that of the shortest side and 3 less than the sum of the lengths of the 2 sides find lengths of 3 sides.
