The perimeter of a triangle is 122 centimeters. If two sides are equally long and the third side is 8 centimeters longer than the others, find the lengths of the three sides.
Answer:
2 sides are 38cm long
The third is 46cm long
Step-by-step explanation:
We can use the following equation to solve
[tex]122 =x + x + (x + 8)[/tex]
Reduce
[tex]122 = 3x + 8[/tex]
114÷3 = x
x = 38
We then add 38 and 8 because the 3rd side is 8cm longer

If f(x) is a linear function ,f(-1)=-3 , and f(4)=-5 , find an equation for f(x)
Answer:
f(x) = -²/₅ x - ¹⁷/₅Step-by-step explanation:
The equation of the linear function: f(x) = mx + b
f(-1) = -3 ⇒ -3 = m(-1) + b ⇒ m = b + 3
f(4)=-5 ⇒ -5 = m×4 + b
-5 = 4(b+3) + b
-5 = 4b + 12 + b
5b = -5 - 12
b = -¹⁷/₅
m = -¹⁷/₅ + 3 = -¹⁷/₅ + ¹⁵/₅ = -²/₅
Therefore the function:
f(x) = -²/₅ x - ¹⁷/₅need help.
