Answer:
1 < x < 3
(1 , 3)
Step-by-step explanation:
We have been provided with a set that is
{x|1 < x < 3}
We have to write it in both as an inequality and also in the form of interval notation.
The inequality can be found easily by just looking at the given set. It states that the set contains x, such that x is greater than 1 and x is smaller than 3, so the inequality can be written as:
1 < x < 3
To write in interval notation, we use brackets, As both 1 and 3 are not included, we'll use round brackets to show the interval.
(1 , 3)
Answer:
Step-by-step explanation:
Question 17
y-y1 = m (x-x1 )
so basically you plug in the (x,y) to y1 and x1 place
Remeber always times it by -1
so answer would be
y-2 = -1/3 (x+4)
Question 18
Pretend its 3x+2y =8
you need to find x or y first im going to find y first
so
- 2y = -3x +8
divide by 2 to isolate y
y = -3/2x - 4
plug it back into the equation
3x + 2(-3/2x) - 4
the x will cancel
so y= -4
Then
plug in the -4 in place of y
SO the Answer is YES because y is horizontal there is -4 = there will be (-3, -4)!
4(2.4)(2)+43
(9.6)(2)+43
19.2+43
62.2
the value of 4n x 2 + 43, when n=2.4, is 62.2
