Use the quadratic formula where -15 = a, 7 = b, 23 = c: [tex]\frac{-b +- \sqrt{b^2 - 4ac}}{2a}[/tex]
Plug in the values: [tex]\frac{-7 +- \sqrt{7^2 - 4(-15)(23)}}{2(-15)}[/tex]
And get: [tex]\frac{-7 +- \sqrt{49 +1380}}{-30}[/tex]
Which simplifies to: [tex]\frac{-7 +- \sqrt{1429}}{-30} = (-7 + 37.8021163)/-30 OR (-7 - 37.8021163)/-30 = 30.8021163/30 OR -44.8021163/30[/tex]
Those are approximately 1 and -1.5

Answer:
No real Solutions
Step-by-step explanation:
Step one: The coefficient on -6x is -6. So b= -6
Step two: Add (b/2)^2 to each side. in our case it is 9
x^2-6x+9= -49
Step three: Factor left side
(x-3)^2 = -49
Step four: take the square root
x-3 = ±√-49
Step five: add 3 to both sides
x = 3 ± √-49
So there is no real solutions
Solve the equation below.
3+X= -8
Answer:
x = -11
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, subtract 3 from both sides of the equation:
3 + x = -8
x + 3 (-3) = -8 (-3)
x = -8 - 3
Simplify:
x = -8 - 3
x = -11
x = -11 is your answer.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4 and each adult ticket sells for $8.50. The auditorium can hold at most 79 people. The drama club must make no less than $460 from ticket sales to cover the show's costs. If 53 student tickets were sold, determine the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses. If there are no possible solutions, submit an empty answer.
Answer:
There is no way.
Step-by-step explanation:
4 x 53 = 212.
460 - 212 = 248.
The mininmum adult tickets you would need is 29 but that would go over the capacity

Chloe has 18inches of red licorice.Reid has 6inchex of red licorice. what fraction of a yard of red licorice do Chloe and Reid have together. use numbers pictures or Words to show your thinking
Answer:
2/3
Step-by-step explanation:
Chloe = 18inches of red licorice.
Reid = 6inches of red licorice
Total = 18 inches + 6 inches
= 24 inches
what fraction of a yard of red licorice do Chloe and Reid have together
Chloe and Reid have 24 inches altogether
1 yard = 36 inches
Fraction = 24 inches / 36 inches
= 2/3

Avery and Carmen both have summer jobs Avery gets paid $360 every four weeks, and gets paid $480 every six weeks summer break lasts a total of 12 weeks who earn more money during summer break every earns dollars per week Carmen earns dollars per week
Answer:
Avery earns $1,080 during summer
Avery weekly earnings = $1,080 / 12
= $90
Carmen earns $960 during summer
Carmen weekly earnings = $960/12
= $80
Carmen earns more money during summer break
Step-by-step explanation:
Avery payment = $360 every four weeks
Carmen payment = $480 every six weeks
summer break lasts a total of 12 weeks
Avery pay during summer = Total summer break weeks / 4 weeks × payment per 4 weeks
= 12 / 4 × $360
= 3 × $360
= $1,080
Carmen pay during summer = Total summer break weeks / 6 weeks × payment per 6 weeks
= 12 / 6 × $480
= 2 × $480
= $960
Avery earns $1,080 during summer
Avery weekly earnings = $1,080 / 12
= $90
Carmen earns $960 during summer
Carmen weekly earnings = $960/12
= $80
Carmen earns more money during summer break
Answer:
Step-by-step explanation:
Avery earns $1080 in 12 weeks
Carmen earns $960 in 12 weeks

how do you find the LCM??
Look at the multiples of the two numbers and find the lowest one that matches e.g.
7 = 7, 14, 21, 28
4= 4, 8, 12, 16, 20, 24, 28
28 is the LCM of 7 and 4
Answer:
Step-by-step explanation:
one away to find to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number . if the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
Which numbers are divisible by 5?

3:135, 211, 330, 274, 252
4:232, 250, 365, 225, 210
Answer:
2. 134, 205, 330, 275, 365
Step-by-step explanation:
All number ending in 0 or 5 can be divisible by 5, besides 0, obviously. So, looking at the options, we can rule out 1, 3 and 4, leaving 2.

How many hours are in 17 years? Write your answer in scientific notations with 3 sig figs.
Sig figs are: are the number of digits in a value, often a measurement, that contributes to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers.
Answer:
1.49 x [tex]10^{5}[/tex] hours
Step-by-step explanation:
1 day=24hours
1 year=365 days
365days=24 x 365=8760hours
17 years
= 8760hours x 17
=148920hours
=1.4892 x [tex]10^{5}[/tex]
= 1.49 x [tex]10^{5}[/tex] hours
Answer:
1.49 x hours
Step-by-step explanation:
1 day=24hours
1 year=365 days
365days=24 x 365=8760hours
17 years
= 8760hours x 17
=148920hours
=1.4892 x
= 1.49 x hours
You start at (10, 1). You move down 1 unit and left 7 units. Where do you end?
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (10, 1).
Down 1 unit:
(10, 1 - 1) = (10, 0)
Left 7 units:
(10 - 7, 0) = (3, 0)
You end at (3, 0)

The formula K= C + 273 is used to
convert temperatures from degrees
Celsius to Kelvin. Solve this formula
for C.
Answer:
c = k - 273
Step-by-step explanation:
solve for c: k = c + 273
flip the equation: c + 273 = k
add -273 to both sides: c + 273 + -273 = k + -273
answer: c = k - 273
