Answer:
True.
Step-by-step explanation:
Let me clear it to you by an example:
if you take n=1,3,5,7,...... which are odd numbers
then adding 1 with them will give you n+1=2,4,6,8.... which are even numbers.
That's how, if an integer n is odd, then n+1 must be even.
Similarly, if you let n as even numbers, then n+1 will be odd.
Answer:
y = - 140
Step-by-step explanation:
The statement
y varies jointly as x & z is written as
<h3>y = kxz </h3>
to find y when x = 7 and z = -5 we must first find the relationship between the variables
when y = - 180
z = 15
x = - 3
- 180 = k(15)(-3)
-180 = - 45k
Divide both sides by - 45
k = 4
The formula for the variation is
<h2>y = 4xz</h2>
when
x = 7
z = -5
y = 4(7)(-5)
y = 4(-35)
<h3>y = - 140</h3>
