which description best describes the solution to the following system of equations y= -2x +3 y= -x + 1
marin [14]
For this case we have the following system of equations:
 y = -2x +3

y = -x + 1
 Equating the values of y we have:
 -2x +3 = -x + 1

 From here, we can clear the value of x.
 We have then:
 -2x + x = 1 - 3

-x = -2

x = 2
 Then, we look for the value of y.
 For this, we substitute x in any of the equations:
 y = -x + 1

y = -2 + 1

y = -1
 Answer:
 
The ordered pair solution of the system of equations, is given by:
 
(x, y) = (2, -1)

In June, Tara gathered data about amusement park attendance on days with different temperatures. Tara used the equation y=−3.5x+
sergij07 [2.7K]

Answer:

25

Step-by-step explanation:

Given the model:

y=−3.5x+400

Number of children in amusement park = y

Temperature = x

On a certain day:

Temperature = 90°F

Number of children in park = 60

Using the model :

The predicted number of children in park when temperature is 90°F would be :

y = - 3.5(90) + 400

y = - 315 + 400

y = 85

Model prediction = 85 children

Actual figure = 60

Residual :

|Actual - predicted | = |60 - 85| = 25 children

Marisa took a survey and discovered that 38 out of 152 students in the seventh grade at her school have more than one pet. What
mamaluj [8]

Answer:

<h3>25%</h3>

Step-by-step explanation:

Total number of student in the school = 152 students

Number of student that have more than one pet = 38

percentage of the students have more than one pet will be expressed as

% of student with more than 1 pet = number of student with more than one pet/total number of student * 100%

% of student with more than 1 pet = 38/152 * 100

% of student with more than 1 pet = 3800/152

% of student with more than 1 pet = 25%

Hence 25% of the students in the school have more than one pet.
