Answer:
12
Step-by-step explanation:
The length of the hypotenuse, PQ, can be found from the Pythagorean theorem:
PQ² = QR² +PR²
PQ² = 3² + 4² = 25
PQ = √25 = 5
The perimeter is the sum of side lengths:
P = 3 + 4 + 5 = 12
The perimeter of this triangle is 12 units.
C, it is a many-to-one function since it is symmetric about the line x=0.75.
For instance f(0.5) = f(1) meaning the x-values 1 and 0.5 both map onto the same y-value.
Answer:
-0.9
Step-by-step explanation:
0.6(x+2)=0.55(2x+3)
Use the distributive property to multiply 0.6 by x+2.
0.6x+1.2=0.55(2x+3)
Use the distributive property to multiply 0.55 by 2x+3.
0.6x+1.2=1.1x+1.65
Subtract 1.1x from both sides.
0.6x+1.2−1.1x=1.65
Combine 0.6x and −1.1x to get −0.5x.
−0.5x+1.2=1.65
Subtract 1.2 from both sides.
−0.5x=1.65−1.2
Subtract 1.2 from 1.65 to get 0.45.
−0.5x=0.45
Divide both sides by −0.5.
x= 0.45/−0.5
x= -0.9
