Answer:

7 pizzas

Step-by-step explanation:

Say: c= cost of pizza, d= delivery fee, p= # of pizzas (final equation)

System: 2c+d=25, 5c+d=58

2c+d=25

<u>-5c-d=-58</u>

-3c=-33

c=11

2(11)+d=25

d=3

p(11)+3=80

p(11)=77

p=7

Alenkinab [10]

Answer:

yes

Step-by-step explanation:

A rational number is in the form p/q where p and q are both integers and the denominator q is not equal to zero. This means that the set of all real numbers are rational numbers.

Since q can be any integer apart from zero, it means that all integers are rational numbers i.e for q = 1.

Hence 2 which can be written as fraction as 2/1 is a rational number since the denominator (q = 1) is a non zero number

Answer:

A.) (x + 2) and (2x - 1)

Step-by-step explanation:

So from the video i just watch this is how its done

3 (2x^2 + 3x - 2) = 0

4  and -1 gives you 3 and you divide them by a which is 2

4/2 (2/1) and -1/2 then you write them from the bottom to top

(x + 2) and (2x - 1)

Answer:

B.) 20 (x + 5) (x - 5) = 0

Step-by-step explanation:

20 (x^2 - 25) = 0

20 (x + 5) (x - 5) = 0

You plant a spruce tree that grows 4 inches per year and a hemlock tree that grows _____ inches per year. The initial heights ar
UNO [17]

<em>Complete Question:</em>

<em>You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year. </em>

<em>The initial heights are shown. </em>

Write a system of linear equations that represents this situation.

Answer:

s(x) = 8 + 4x

h(x) = 14 + 6x

Step-by-step explanation:

Given

Spruce Tree (s):

Initial\ Height = 8

Growth = 4 (yearly)

Hemlock Tree (h):

Initial\ Height = 14

Growth = 6 (yearly)

Required

Represent as system of linear equations

Let the number of years be x.

In both cases, the equation can be formed using:

Equation = Initial\ Height + Growth * x

For Spruce Tree (s):

s(x) = 8 + 4 * x

s(x) = 8 + 4x

For Hemlock Tree (h):

h(x) = 14 + 6 * x

h(x) = 14 + 6x

<em>Hence, the equations are </em>s(x) = 8 + 4x<em> and </em>h(x) = 14 + 6x<em></em>

<h3>Answer: B. Graph is nearly symmetrical</h3>

Explanation:

Given information:

  • A number line going from 2 to 11.  
  • 0 dots are above 2.  
  • 0 dots are above 3.  
  • 1 dot is above 4.  
  • 2 dots are above 5.  
  • 4 dots are above 6.  
  • 4 dots are above 7.  
  • 3 dots are above 8.  
  • 2 dots are above 9.  
  • 2 dots are above 10.  
  • 0 dots are above 11.

From that we can see the data set is {4,5,5,6,6,6,6,7,7,7,7,8,8,8,9,9,10,10} which produces the dot plot you see in the image attachment below.

It's a bit tricky to see, but the graph is nearly symmetrical. If we were to remove the blue points in the dot plot I provided, then we'll get a perfectly symmetrical distribution. Symmetrical means one half is a mirror copy of the the other half. The center line of a symmetrical distribution is both the mean and median.
