Answer:
409
Step-by-step explanation:
296 = 200 + 90 + 6
The value of the 9 is 90 in 296.
1/10 of 90 is 9. The only number that has a 9 in the units digit is 409.
<u>Step-by-step explanation:</u>
From the following figure, We can see that we have a graph with different lines where some points are included and some are not . Let's find out the listed values using graph:
<u>F(-10):</u>
From the graph F(-10) = -6 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(-4):</u>
From the graph F(-4) = 0 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(-2):</u>
From the graph F(-2) = 2 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(0):</u>
From the graph F(0) = -1 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(3):</u>
From the graph F(3) = -7 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
Hello,
1) Verify if it is a 2 degree.
2) y=ax²+bx+c
Calulate a,b,c by Gauss's methode
a=3, b=0,c=-1
y=3x²-1
Answer:
- (-11.70, -2.05), (4.70, 5.10)
Step-by-step explanation:
<u>Given equations</u>
<u>Solving the first equation for x:</u>
- (x+5)(x+2)=65
- x^2 + 7x + 10 = 65
- x^2 + 7x - 55 = 0
- x = (-7 ± √(49+4*55))/2
- x = -11.70, x = 4.70
<u>Then solving for y:</u>
- y= 24/(-11.7) = -2.05
- y = 24/4.7 = 5.10
<u>Solution set: </u>
- (-11.70, -2.05), (4.70, 5.10)
