For each graph, calculate the slope of the line.<br> Whew is the slope between 2,6 and 8,4
Tom [10]

Answer:

-1/3

Step-by-step explanation:

First, slope is change in y over change in x, or rise over run. Plugging these points in, (y2-y1)/(x2-x1)=(6-4)/(2-8), or 2/-6, simplifying, the slope= -1/3.

In the expansion of (ax+1)^7<br> the fifth term is 945x^3<br> Find the value of a.
Advocard [28]

Answer:

a = 3

Step-by-step explanation:

First start writing out the binomial expansion of (ax + 1)^7

[1^7] + [7C1 * 1^6 *(ax)] + [7C2*1^5*(ax)^2]+[7C3*1^4*(ax)^3]

as you can see from this, the last bracket will produce our x^3 term

7C3*1^4*a^3x^3 \\35a^3x^3\\35a^3 = 945\\a^3 = 27\\a = 3

Hope this helps, let me know if you have any questions :)
