Answer:
That parabola hits (-5,0) and (9,0) so the x-intercepts are -5 and 9
Step-by-step explanation:
Use desmos its really helpful
To solve:
-2x = 34
----- -----
-2 -2
(-2x means -2 times x, so to undo this we need to divide by -2 on both sides)
x = -17
Then you do basic division (knowing that a positive divided by a negative results in a negative answer). And that's it!
Answer:
The answer would be 21.248 miles
Answer:
- 2x + y = - 1 , so the B is correct.
Step-by-step explanation:
+ Because of "the line passing through the pair of points (2,3) and (5,9)", that means the line has the equation y = ax + b where a = (9-3)/(5-2)= 6/3= 2
+ So the equation is y = 2x + b.
+ Then we replace x= 2 and y= 3 into y = 2x + b for finding like:
3 = 2*2 + b or 3 = 4 + b, so we find b = 3 - 4 = - 1.
+ The equation of this line is y = 2x - 1 or in the form:
2x - y - 1 = 0 (or -2x + y = -1)
Have a good day!
Answer:
