Step-by-step explanation:
the further your away from zero on the left on a number line the smaller the number gets and the further your away from zero on the right on a number line the greater it gets
Answer:
a = 7
Step-by-step explanation:
The function given is defined at x=1 as ...
f(1) = 3·1² = 3
In order to make the limit from the left be 3, we must have ...
ax -4 = 3 . . . . for x=1
1a = 7 . . . . . . .add 4
The value of the constant "a" is 7.
If you need an estimate for #5, then you can round each value to the nearest whole number to have...
- 21.6 turn into 21
- 20.9 turn into 21
- 19.4 turn into 19
- 18.5 turn into 19
Add up those values: 21+21+19+19 = 80
-------------------
Another estimate you could do is to round everything to 20, since we're close to this value. Having four copies of 20 added leads to 20+20+20+20 = 80
So they rode a total estimated amount of 80 miles
--------------------
The actual total is: 21.6+20.9+19.4+18.5 = 80.4 miles, which isn't too far off from 80.
Answer: 2y + 11x = -104
Step-by-step explanation:
The formula for calculating equation of line given two points is :
=
= -10
= -8
= 3
= -8
substituting the values into the formula , we have :
=
=
2(y - 3 ) = -11 ( x +10 )
2y - 6 = -11x - 110
2y + 11x = -110 + 6
2y + 11x = -104
Therefore : the equation of the line in standard form is 2y + 11x = -104
