What’s the gradient and y intercept for c and e and could u explain pls thx

kifflom [539]

Step-by-step explanation:

if you are given an equation of a form y=kx+b, k is gradient and b is y-intercept

in c you can write this equation as y=(2x/3)-2,so gradient = 2/3 and y-intercept =-2

in e:6y=2x+3

y=x/3+1/2,gradient = 1/3, y-intercept=1/2

Find the tenth term of the geometric sequence, given the first term and common ratio.

Natalija [7]

Answer:

$a_{10}=\dfrac{1}{128}$

Step-by-step explanation:

In the geometric series:

$a_1=4\\ \\r=\dfrac{1}{2}$

The nth term of the geometric sequence can be calculated using formula

$a_n=a_1\cdot r^{n-1}$

In your case, n = 10, then

$a_{10}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^{10-1}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^9\\ \\=2^2\cdot \dfrac{1}{2^9}\\ \\=\dfrac{1}{2^{9-2}}\\ \\=\dfrac{1}{2^7}\\ \\=\dfrac{1}{128}$

What is y=-x+6?........

SIZIF [17.4K]

Answer:

Slope = -2/2 = -1

x-intercept = 6/1 = 6

y-intercept = 6/1 = 6

I wasn't sure what you really were asking for, so I did slope, x, and y.

3/5 x 1/5+1/5 x 73/3

insens350 [35]

So,

3/5 x 1/5 = 3/25

3/25 + 1/5 = 8/25

8/25 x 73/3 = 7 59/75

I hope this helps
