Answer:The blue line is the tangent line that passes through the point (0.75, 0.25). The point on the tangent line is (3, 4). The gradient of the curve is approximately 0.6. Note: Parallel lines have the same gradient.
Step-by-step explanation:
The range of the data is C. 160 because the biggest number, 280, subtracted by the smallest number, 120, is equal to 160.
Answer:
See below.
Step-by-step explanation:
Values are excluded if they make the denominator zero, so one rational expression could be:
(x^2 - 9) / (x + 4)(x + 7)
- when x = -4 or -7 then the denominator is zero so the values of the function is undefined for these values.
Answer:
-12
Step-by-step explanation:
-4-(5+3)
-4-(8)
-4-8
-12
What you need to do is multiply both sides by the same number. If 8 times 6 is 48, then 7 times 6 is your answer.
