Variables: x, w
Coefficients: -1, 3
Constants: 7, -9
2.b. -g + 8k - 3 - 7
Terms: -g, 8k, -3, -7
Variables: g, k
Coefficients: -1, 8
Constants: -3, -7
3.a. correct
3.b. correct
3.c. -5+ 4x = -x
4.a. 4(2x + 3) = 8x + 12
4.b. -2(3x + 4) = -6x - 8
4.c. -5(2x - 3) = -10x + 15
You find the range by plugging 0 ,2 and 4 into x^2 + 1.
for x = 0 y = 0 + 1 = 1
x = 2, y = 2^2 + 1 = 5
x = 4 y = 4^2 + 1 = 17
so the range is {1, 5, 17}
Answer:
5.62 I used a calculator to find the answer
Answer:
11 feet, 26 feet, 29 feet
Step-by-step explanation:
(2x+4 middle) + (3x- 4 longest) + (x smallest )= 66
2x +3x +x +4 - 4= 6x
6x = 66
x= 66/6
x = 11
smallest = 11 feet
middle = 2(11) + 4 = 26 feet
longest = 3(11) -4 = 29 feet
