y = 7x - 3
Note the gradient of the tangent is the derivative of y at x = 1
Differentiate using the power rule
(a
) = na
y = 3x³ - x² + 2
= 9x² - 2x
x = 1 : = 9 - 2 = 7 ← gradient of tangent
equation in point- slope form, using m = 7 and (a, b) = (1, 4)
y - 4 = 7(x - 1) ← point-slope form
y - 4 = 7x - 7
y = 7x - 3 ← in slope-intercept form
Answer:
<h2>
Point Z</h2><h3>
Step-by-step explanation:</h3><h3>
</h3>
When you go to -0.5, x, you go to the left 2 times, start at 0, then move to the left 2 times.
Points G and B are incorrect.
When you go to 0.75, you move up 3 times, start at 0, then move upwards 3 times.
Best of Luck to you.

Answer:
x = 0
Step-by-step explanation:
x-5/3=1=3-2x-2
No becuase Javier has to drive 3 hours. 40 times 3=120
Answer:
8 points
Step-by-step explanation:
Given that there are 4 teams and Each team plays each of the other teams exactly once, then each team plays 3 matches. The possible points after 3 matches are:
0: 3 lost
1: 2 lost, 1 tied
2: 2 tied, 1 lost
3: 3 tied
4: 1 won, 1 lost, 1 tied
5: 1 won, 2 tied
6: 2 won, 1 lost
7: 2 won, 1 tied
9: 3 won
