Can someone solve this
marishachu [46]

Answer:

x = -44.3

Step-by-step explanation:

2x+450 = 7-8x

Add 8x to each side

2x+8x+450 = 7-8x+8x

10x+450 =7

Subtract 450 from each side

10x+450-450 = 7-450

10x = -443

Divide each side by 10

10x/10 = -443/10

x = -44.3

What is the y-intercept of y = sinx?​
alexdok [17]

Answer:

The y-intercept is 0

Step-by-step explanation:

Here, we want to get the y-intercept value of y = sin x

From the plot of the graph, we can see that the graph of sin x touches the y-axis at the point y = 0

So therefore, the y-intercept of y = sin x is 0

The explicit formula for an arithmetic sequence is an = 20 + (n − 1)(2). What is the 200th term?
Andrews [41]

Answer:

a_{200}=418

Step-by-step explanation:

The explicit formula for an arithmetic sequence is given by :

a_n=20+(n-1)2 ...(1)

We need to find the 200th term of the sequence.

Put n = 200 in equation (1)

a_{200}=20+(200-1)2\\\\=20+199\times 2\\\\=418

So, the 200th term of the sequence is 418.
