Step-by-step explanation:
A
x + 3y = 5
(x, y) = (2,1)
x + 3y = 5
2 + 3(1) = 5
2 + 3 = 5
5 = 5
The equation is true
B.
y = –x + 3
(x, y) = (2, 1)
y = –x + 3
1 = -2 + 3
1 = 1
The equation is true
Answer:
fruit-21
lemonade -14
Step-by-step explanation:
to find out how many parts you have you add 3 and 2 together, this gives you 5, 36÷5=7 so for every 1 of each you have 7, 3×7=21, 2×7=14
A. The function f(-2) is larger than f(2)
B. The function f(4) is smaller than f(0)
Given,
The function; f(x) = x²- 5x + 1
We have to find;
A. The larger is f(2) or f(-2)
Here,
f(2) = 2²- 5 x 2 + 1 = 4 - 10 + 1 = - 6 + 1 = -5
f(-2) = -2²- 5 x -2 + 1 = 4 + 10 + 1 = 15
That is,
The function f(-2) is larger than f(2)
B. The smaller is f(0) or f(4)
Here,
f(0) = 0²- 5 x 0 + 1 = 0 - 0 + 1 = 1
f(4) = 4²- 5 x 4 + 1 = 16 - 20 + 1 = - 4 + 1 = -3
That is,
The function f(4) is smaller than f(0)
