What are the x-intercepts of the graph of the following equation ?
y = -x2 - 4x + 12
(Show work)
Answer:
x-intercepts: (-6, 0) , (2, 0)Step-by-step explanation:
x-intercepts are points where y=0
[tex]y = -x^2 - 4x + 12\\\\y=0\quad\iff\quad -x^2 - 4x + 12=0\\\\{}\qquad\quad\quad a=-1\,,\ b=-4\,,\ c=12\\\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(4)\pm\sqrt{(-4)^2-4\cdot(-1)\cdot12}}{2\cdot(-1)}=\dfrac{4\pm\sqrt{16+48}}{-2}\\\\x_1=\dfrac{4+\sqrt{64}}{-2}=\dfrac{12}{-2}=-6\ ,\quad x_2=\dfrac{4-8}{-2}=\dfrac{-4}{-2}=2[/tex]
x-intercepts: (-6, 0) , (2, 0)

Eric starts picking strawberries after Jody had already picked 12 pounds. If Eric picks at a rate of 8 pounds
per hour and Jody picks at a rate of 6 pounds per hour, how many whole hours after Eric starts picking will
the total weight of picked strawberries exceed 100 pounds? Explain how you found your answer.
Answer:
It will take him eight hours to get to one hundred pounds of strawberries/ nine hours to get to one hundred and eight pounds
Step-by-step explanation
H - hours 8 represents number of lbs Eric picks in H amount of hours
8h + 12 = 100
-12 -12
8h= 88
8h/8= 88/8
H=8
Emily ate 1/10 of a box of cereal. Her serving was 2/3 of a cup. How many cups were in the entire box?
Answer:
6 2/3.
Step-by-step explanation:
Since 1/10 of the box is equal to 2/3 all we need to do is multiply 2/3 by 10. Or add 2/3 to itself 10 times if that makes it easier for you.
2/3 x 10 = 6 2/3
(since I didn't convert 10 into a fraction by making it 10/1 it came out as a decimal. "6.66666666667 ." Which when converted to a fraction makes it 6 2/3. In case you were confused if you used a calculator for just "2/3 x 10".)
6 2/3 is your answer.
Hope this helps and have a nice day!

Leah is creating satin bows for wedding from a 15 meter long ribbon she first cuts a piece 3 4/9 meters long then she cuts a piece 6 5/9 meters long from the remaining ribbon how much ribbon does Leah have left
Answer:
Leah has 5 meters of ribbon left.
Step-by-step explanation:
Operations with fractions
Fractions can be defined as the quotient of two integer numbers. There are three types of fractions:
* Proper fractions: When the numerator is less than the denominator. Example: 2/5
* Improper fractions: When the numerator is greater than or equal to the denominator. Examples: 7/5, 13/13
* Mixed fractions: They are given as an integer followed by a proper fraction. Example: [tex]\displaystyle 4\frac{1}{3}[/tex]
Leah has a 15-meter long ribbon and is creating satin bows for weddings. She takes two pieces out of it. The total length of ribbon taken is the sum of both fractions:
Total cut:
[tex]\displaystyle 3\frac{4}{9}+6\frac{5}{9}[/tex]
To add these fractions, we add the integer parts and apart from the proper fractions:
[tex]\displaystyle 3\frac{4}{9}+6\frac{5}{9}=3+6+\frac{4}{9}+\frac{5}{9}=9+\frac{9}{9}=9+1=10[/tex]
Now we can calculate the remaining length of ribbon:
Remaining riboon= 15 m - 10 m = 5 m
Leah has 5 meters of ribbon left.

x² = √20² - 4²x² = 4x = 2The relationship between x and y is proportional. When x is 3, y is 51. What is x when y is 204? Enter your answer in the box.
Answer:
12
Step-by-step explanation:
Use the relation between 3 is to 51
eventually... you will
The relationship between x and y is proportional. When x is 3, y is 51. The value of x will be 3468 when y is 204.
What is a proportional relationship?
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that, the relationship between x and y is proportional. When x is 3, y is 51.
Since the relationship between x and y is proportional. The constant ratio of the two proportional values y/x is represented by the symbol k, which may be a positive rational number. The x value and the y value are directly proportional, as in the equation y = kx.
x ∝ y
x=ky
k=y/x
k=51/3
k=17
We have to find the value of x when y is 204.
x=ky
x=17×204
x=3468
Thus, the relationship between x and y is proportional. When x is 3, y is 51. The value of x will be 3468 when y is 204.

During a three-day period, a provincial hospital received 24 new patients and discharged 6 on the first day, received 8 and discharged 21on the second day, and received 9 and discharged 6 on the third day. How did the number of patients in the hospital at the end on the third day compared with the number at the start at of the three-day period
Answer:
1 : 3
Step-by-step explanation:
Given the following :
First day :
Patient received = 24
Patient discharged = 6
Second day :
Patient received = 8
Patient discharged = 21
First day :
Patient received = 9
Patient discharged = 6
Number of patient in the hospital at the end of the third day:
Patients received = (24 + 8 + 9) = 41
Patients discharged = (6 + 21 + 6) = 33
Patient received - patient discharged
= (41 - 33) = 8
Number of patients in hospital at the start of the three day period :
Patient received on first day = 24
Patient at the end : patient at the start
8 : 24 = 1 : 3
