Since we are given two ordered pairs or points, therefore we can use the point-slope formula to create the linear model.

The general equation is in the form of:

y = mx + b

where m is the slope and b is the y-intercept

The slope can be calculated as:

m = (y2 – y1) / (x2 – x1)

m = (12.4 – 14.2) / (2000 – 1990)

m = -0.18

SO:

y = -0.18x + b

Choosing any ordered pair to calculate for b:

12.4 = -0.18(2000) + b

b = 372.4

Hence,

y = -0.18x + 372.4

16. Find the values of x and y. (2y + 5) (5x - 17) (3x – 11)º

serg [7]

Answer:

x = 26

y = 9

Step-by-step explanation:

(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)

Solve for x

5x - 17 + 3x - 11 = 180

Collect like terms

5x + 3x - 17 - 11 = 180

8x - 28 = 180

Add 28 to both sides

8x = 180 + 28

8x = 208

Divide both sides by 8

x = 208/8

x = 26

Also:

(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)

Plug in the value of x and solve for y

2y + 5 + 90 + 3(26) - 11 = 180

2y + 5 + 90 + 78 - 11 = 180

Collect like terms

2y + 162 = 180

Subtract 162 from both sides

2y = 180 - 162

2y = 18

y = 9 (dividing both sides by 2)

Suppose the band sells erasers for $2 per package and pencils for $5 per package. The band sells 220 packages in all and earns a

garik1379 [7]

Let e=erasers and p=pencils. So we know the total amount of erasers plus pencils sold is equal to 220. Therefore,

$e + p = 220$
We also know the cost of erasers and pencils totaled to $695 in earnings and so:

$2e + 5p = 695$
and so those are your two equations.
