Answer:
3 ≤ x ≤ 7 or x is between 3 and 7, inclusive
Step-by-step explanation:
Eira's graph probably resembled the diagram below.
The domain is the set of all possible x-values that will make a function work.
x can take any value from 3 to 7.
The domain is [3, 7] or 3 ≤ x ≤ 7.
The answer is D. 2+1/5×(7/12+3)
Answer:
false
Step-by-step explanation:
x=4andy=7
2×4+7 isnot equal to 7
Answer:
y = -3x - 3
Step-by-step explanation:
First, determine the slope of the red line. As we move from (0, 3) to (1, 0),
x increases by 1 and y decreases by 3. Hence, the slope, m, is
m = rise / run = -3 / 1, or m = -3.
The desired new line, parallel to the red line, has the same slope as the red line: m = -3.
The equation for this new line is y - k = m (x - h), where (h, k): (-1, 0):
We get y - 0 = -3 (x + 1), or y = -3x - 3.
Check: Does this line go thru the given point (-1, 0)?
Is 0 = -3(-1) - 3 true? Yes, it is true.
