Answer:
x = -7, x = 9
Step-by-step explanation:
We presume your equation is ...
x² -2x -63 = 0
Factors of -63 that have a sum of -2 are -9 and +7. Then the factored equation is ...
(x -9)(x +7) = 0
Solutions make the factors zero.
x -9 = 0 ⇒ x = 9
x +7 = 0 ⇒ x = -7
The solutions to the quadratic equation are x = -7 and x = 9.
Answer:
5/4 =x
7/4 =y
Step-by-step explanation:
We can use proportions to solve. Put the small triangle side over the big triangle side
5 8
---------- = -------------
5+x 10
Using cross products
5*10 = 8(5+x)
Distribute
50 = 40+8x
Subtract 40 from each side
50-40 =40-40+8x
10 = 8x
Divide by 8
10/8 = 8x/8
5/4 =x
7 8
---------- = -------------
7+y 10
Using cross products
7*10 = 8(7+y)
Distribute
70 = 56+8y
Subtract 56 from each side
70-56 =56-56+8y
14 = 8y
Divide by 8
14/8 = 8y/8
7/4 =y
Answer:
x>0 (0,~)
Step-by-step explanation:
3(x-2)-(1-x)>2x-7
3x - 6 - 1 +x > 2x -7
4x -7 > 2x -7
4x - 2x > -7 +7
2x > 0
x>0
If you don't understand why you can ask me back
1. Exponential would be the best option to model the data because of the large increase. It would be more difficult to model it linear because the linear values would jump from 10 to 34 to 91 etc. there is a no correlation between them.
2. We can tell which function is the best based on the y values and x values. Especially with key words like double or triple we know that’s it going to be exponential. Linear would be like if we were presenting a graph for tickets and prices which is a straight line with increasing x and y values and the rate of change is constant.
Exponential usually have a consistent multiplier so it won’t be the same but there will be a pattern.
3. 4 data points would be 1,2,3,4 for x values and for y (2,4,6,8). I set up the data to be constant the x values are adding by 1 and the y values are added by 2. If we were graphing this it would obviously be a straight line.
