Step-by-step explanation:
I believe this is correct Hope that helps ya.
There 10 dines in a dollar 10 times 5 = 50 so u have 50 dimes <span />
To do these problems, you plug in the ‘n’ value given into the equation.
a. 6j - 3 : j = 4
6(4) - 3
24 - 3
21
b. 1/2b + 5 : b = 14
1/2(14) + 5
7 + 5
12
c. 8 + 4k : k = 3.5
8 + 4(3.5)
8 + 14
22
Answer:
(see attached workings)
y = -4x + 2
y = (4/5)x + 2/5
Step-by-step explanation:
- Rewrite the function to make y the subject.
- Find the x values of the points when y=-2 by substituting y=-2 into the rewritten function
- Differentiate the function
- Input the found values of x into the differentiated function to find the gradients of the tangents to the curve at y=-2
- Use the equation of a straight line and the points where y=-2 and the found gradients to find the equation of the tangent lines.
