Answer: Inequality
Step-by-step explanation:
From the question, if we can describe 15×-10 as an expression, then we would describe 6×-2< 35 as an inequality. An
inequality is used to compare two values, and shows if one is less than, or greater than, or maybe not equal to the other value.
For example, a ≠ b means that a is not equal to b and a < b means a is less than b while a > b means a is greater than b. From the question, 6×-2< 35 means that 6x - 2 is less than 35.
Answer: x2= 6
FYI: The x2 is x squared
Step-by-step explanation:
Simplifying
4x2 + 7 = 31
Reorder the terms:
7 + 4x2 = 31
Solving
7 + 4x2 = 31
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 4x2 = 31 + -7
Combine like terms: 7 + -7 = 0
0 + 4x2 = 31 + -7
4x2 = 31 + -7
Combine like terms: 31 + -7 = 24
4x2 = 24
Divide each side by '4'.
x2 = 6
Simplifying
x2 = 6

2. The linear regression function of a graphing calculator can be used to find the line of best fit. Generally, this involves entering the given coordinates and invoking the appropriate regression calculation.
... calories ≈ 13.9×(fat grams) + 191.3
Answer: y = 10x
This line goes through the two points (0,0) and (1,10)
(0,0) means x = 0 and y = 0 pair up. At time x = 0 seconds, aka the starting time, the height is y = 0 (the balloon is on the ground).
(1,10) means x = 1 and y = 10 pair up. At time x = 1 second, the balloon is y = 10 feet off the ground.
Median is 17
Range is 17.4
IQR is 6
