Answer:
No, it is not a right triangle
Step-by-step explanation:
Let H = 14 cm
B = 3 cm
P = 13 cm
According to pythagoras theorem:
H^2 = P^2 + B^2
14^2 = 13^2 + 3^2
196 = 169 + 9
196 is not equal to 178
Hence, it is not a right triangle
Answer:
- domain: x ≥ 0
- range: y ≥ 0
Step-by-step explanation:
The domain of a function is the set of x-values for which it is defined. The range of a function is the set of y-values the function produces.
<h3>Domain</h3>
The domain is the horizontal extent of the graph. This graph extends from x=0 toward x→∞. The domain is x ≥ 0. In interval notation, it is written [0, ∞).
<h3>Range</h3>
The range is the vertical extent of the graph. This graph extends from y=0 toward y→∞. The range is y ≥ 0. In interval notation, it is written [0, ∞).
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
