Answer:

6 balloons

Step-by-step explanation:

Clowns Are Fun equation is

y = 1.25x + 6  (1.25 per balloon plus the flat rate $6 delivery charge)

Singing Balloons equation

y = 1.95x + 2  (1.95 per balloon plus the flat rate $2 delivery charge)

We want to know know the value of x that makes Clowns are Fun less that Singing Balloons, so we have the inequality..

1.25x + 6 < 1.95x + 2      now solve for x

4 < 0.7x                

  5.7 < x          We can't have 0.7 of a balloon, so we round to 6.  

So when she orders 6 or more balloons, the cost of Clowns Are Fun will be cheaper that the cost of Singing Balloons

Simplify (1-√3)(⅓+√3) leaving your answer in the form p+q√3​
Mars2501 [29]

Answer:

\frac{-8 +2\sqrt{3} }{3}

Step-by-step explanation:

When working with surds we need to take note of the roots present there.

To expand this equation we can do it the following way noting that √3 X √3 = 3

<em></em>

<em>Expanding (1-√3)(⅓+√3)</em>

1 X 1/3 = 1/3

1 X √3 = √3

-√3 X 1/3 =-√3/3

√3 X √3 = 3

hence, expanding the equation, we have

1/3 + √3 -√3/3 + 3

We can simply group the like terms and add them up.

[1/3 +3] +[√3-√3/3]

10/3 + \frac{2\sqrt{3} }{3}

= \frac{-8 +2\sqrt{3} }{3}

What is the solution to this system of equations<br>(5z +y=2<br>( 47 +y=5​
prisoha [69]

Answer:

Z = 8.8 Y = - 42

Step-by-step explanation:

Y = 2 - 5Z

Y = 5 - 47

2 - 5Z = 5 - 47

- 5Z = - 44

5Z = 44

Z = 8.8

Y = 2 - 5 (8.8)

Y = 2 - 44

Y = - 41

Y = 5 - 47

Y = - 42

Determine the x and y intercepts
kakasveta [241]
Answer:
x-intercepts: (2,0), (4,0)
y-intercepts: (0,-8)

Explanation:
To find the x intercept(s), you must compute where y=0. So solve 0= -x^2 + 6x - 8. So, the x intercepts are: (2,0) and (4,0) since the solutions to the mentioned equation are x=2 and x=4. To find the y intercept(s) compute what is y when x=0. In this case, when x=0, y=-8. So the only y intercept is (0,-8).
