Answer:
5 3/5
Step-by-step explanation:
17/5+11/5=28/5=5 3/5
Answer:
See below
Step-by-step explanation:
Question 2:
A relation is a function if every different x-value has a y-value. Since this relation has two outputs for x = 4 (1 and 9), it is NOT a function.
Question 3:
Plug the three points listed (-1, 0, 1) into the function and get their outputs. This will be the range.
f(x) = 2x + 4
Plug in -1.
f(-1) = 2(-1) + 4
f(-1) = -2 + 4
f(-1) = 2
f(x) = 2x + 4
Plug in 0.
f(0) = 2(0) + 4
f(0) = 4
f(x) = 2x + 4
Plug in 1.
f(1) = 2(1) + 4
f(1) = 2 + 4
f(1) = 6
This makes the range {2, 4, 6}.
(x - y) • (y + 4)
Have a great day!
Answer:
30 cm^2
Step-by-step explanation:
a = 13 cm
b = 12 cm
using Pythagorean theorem:
a^2 = b^2 + c^2
--> c^2 = a^2 - b^2 = 13^2 - 12^2 = 169 - 144 = 25
--> c = √25 = 5
The area of that right triangle is:
S = b.c / 2 = 12 . 5 / 2 = 30 (cm^2)
