In 3-4 sentences, describe how you would find a line parallel to the line 2x + 5y = 15 that goes through the point (-10, 1). Be

larisa86 [58]

the parallel line is 2x+5y+15=0.

Step-by-step explanation:

ok I hope it will work

soo,

Solution

given,

given parallel line 2x+5y=15

which goes through the point (-10,1)

now,

let 2x+5y=15 be equation no.1

then the line which is parallel to the equation 1st

2 x+5y+k = 0 let it be equation no.2

now the equation no.2 passes through the point (-10,1)

or, 2x+5y+k =0

or, 2*-10+5*1+k= 0

or, -20+5+k= 0

or, -15+k= 0

or, k= 15

putting the value of k in equation no.2 we get,

or, 2x+5y+k=0

or, 2x+5y+15=0

which is a required line.

This list shows concentrations of carbon dioxide (in parts per million) in the Earth's atmosphere for the years 1950, 1955, 1960

Marat540 [252]

Answer:

Choice B

The mathematical model that best fits the data is a polynomial of order 2 as shown on the attachment.

The predicted global mean temperature in 2015 is; 412.24

Step-by-step explanation:

The first step is to obtain a scatter plot of the data and then fit a trend line. A quadratic polynomial fits the data well considering the large value of the coefficient of determination of 0.9984.

To determine the global mean temperature in 2015 we substitute x with 14 in the quadratic model;

y = 0.4643(14)^2 + 0.7976 (14) + 310.07

= 412.24

Derek collects quarters that have the names of the 50 U.S. states on them. He has collected 12

Lelechka [254]

Time taken to collect 12 different state quarters is 2.5 months.

Now , we need to find time taken to collect all 50 state quarters.

Let , time required is x.

So,

$\dfrac{x}{50}=\dfrac{2.5}{12}\\\\x=\dfrac{2.5}{12}\times 50\\\\x=10.4$

Therefore, time required is 10.7 months.

Hence, this is the required solution.
