Answer:
I think this is the answer there are two i believe
Step-by-step explanation:
x =(15-√345)/6=5/2-1/6√ 345 = -0.596
or
x =(15+√345)/6=5/2+1/6√ 345 = 5.596

y = x2 - 3x + 6
y = 2x + 6
A. (0,6) and (5, 16)
B. (-5, - 4) and (0,6)
C. (-5, - 4) and (0-6)
D. (0,-6) and (5, -16)
Step-by-step explanation:
y = x² - 3x + 6
y = 2x + 6
y = y
x² - 3x + 6 = 2x + 6
x² - 5x = 0
x(x - 5) = 0
x = 0 and x = 5
y = 2x + 6 and y = 2x + 6
y = 2(0) + 6 and y = 2(5) + 6
y = 0 + 6 and y = 10 + 6
y = 6 and y = 16
(x1,y1) and (x2, y2) = (0,6) and (5,16)

Each chef at "Sushi Emperor" prepares 15 1515 regular rolls and 20 2020 vegetarian rolls daily. On Tuesday, each customer ate 2 22 regular rolls and 3 33 vegetarian rolls. By the end of the day, 4 44 regular rolls and 1 11 vegetarian roll remained uneaten. How many chefs and how many customers were in "Sushi Emperor" on Tuesday?
Answer:
2 chefs and 13 customersStep-by-step explanation:
Let the number of chefs is x and the number of customers is y.
Regular rolls
Prepared 15x, eaten 2y, left 4Equation:
15x = 2y + 4 >>> (1)Vegetarian rolls
Prepared 20x, eaten 3y, left 1Equation:
20x = 3y + 1 >>> (2)We have a system.
Solve it by elimination, multiply the first one by 4 and the second one by 3:
15x*4 = 2y*4 + 4*4 ⇒ 60x = 8y + 1620x*3 = 3y*3 + 1*3 ⇒ 60x = 9y + 3Compare the equations:
8y + 16 = 9y + 39y - 8y = 16 - 3y = 13Substitute the value of y into first equation and solve for x:
15x = 2*13 + 415x = 30x = 2Answer:2 Chefs and 13 customers.

Answer:
[tex]\sqrt{2}[/tex]
Step-by-step explanation:
A rational number has the form
[tex]\frac{a}{b}[/tex] , where a and b are integers
Given
- [tex]\sqrt{2}[/tex] ( multiplying by [tex]\sqrt{2}[/tex] gives )
- [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex]
= - 2
= [tex]\frac{-2}{1}[/tex] ← a rational number
What is the area of this triangle? A=B x H 12
Height= 127 ft
Base= 13ft
Answer:
The area of this triangle is 825.5 square feet
Step-by-step explanation:
For a given Triangle
Base = 13 ft
Height = 127 ft
Now, Area of Triangle
A = ½ × b × h
A = ½ × 13 × 127 ft
A = ½ × 1751 ft
A = 825.5 square feet
Thus, The area of this triangle is 825.5 square feet.

What are the blank numbers for 16, 17, 18, and 19
Answer:
16: 0.5, 5, 7.5
17: 62, 434, 682
18: 12.3, 62.5, 10
19: 1, 75, 300
Step-by-step explanation:
16: 9/18=0.5 so halve the numbers
17: 186/3=62 so multiply numbers by 62
18: 24.6/2= 12.3 so multiply by 12.3 and divide for the last one
19: 125/5=25 so for the first one divide by 25 and for the last two times by 25

Is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer.
Please use your own words im not tryna get in trouble.
Answer:
No, the two triangles can not be proven to be congruent with the given information. The reason that it can't be proven is due to there being a missing measurement. The triangles could be proven to be congruent if there was an angle given or if the other side was shown to be congruent.
Step-by-step explanation:
This is in my own words not taken from the internet but i suggest that you reword it because our wrighting styles are probably different and sometimes you can get counted off for that. I hope this helps!
What is the slope of the line?
Answer:
[tex]m=-3[/tex]
Step-by-step explanation:
When looking at the graphed line we can see that point A is [tex](-1,0)[/tex] and point B is [tex](0,-3)[/tex] so in order to find the slope of these two points we use the slope formula
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } =\frac{rise}{run}[/tex]
[tex]m=\frac{-3}{1} =\frac{rise}{run}[/tex]

What is the slope?
……
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

saturated fat than protein? Draw decimal
models to find the difference.
The difference between the amount of saturated fat and protein can be calculated using the subtraction operation. Hence, the difference is 0.59 grams.
Given the Parameters :
Grams of Saturated Fat = 1.08 grams Grams of protein = 0.49 gramsUsing the subtraction operation :
Grams of Saturated Fat - Grams of Protein 1.08 g - 0.49 g = 0.59 gramsHence, the amount of saturated fat is 0.59 grams more than Protein.

Answer:
132.3
Step-by-step explanation:
A= 2 π r h+2 π r²
A=2×3.14×3×4+2×3.14×3²
A=6.3×3×4+6.3×9
A=75.6+56.7
A=132.3
(π is rounded up to 3.14)
NOTE:
The answer might defer from the calculator answer (which is 131.9) and that is because the value of pi taken by the calculator is the whole value and here it is rounded up to 3.14 which is what you take when calculating manually
