The best thing I can think of is
((2)(4))(.5+1)=(2)(6)
because (2*4)(1.5)= 8*1.5
= 12
and 2*6 =12
and 12=12
I hope this is right and I hope it helps!
Answer:
The function input is -20 when the output is 25
Step-by-step explanation:
we have

where
y is the dependent variable or output
x is the independent variable or input
If the output is 25
then
y=25
substitute

Solve for the function input is the same that solve for x
Isolate the variable x
Adds 5x both sides


subtract 25 both sides


Divide by 5 both sides

therefore
The function input is -20 when the output is 25
Answer:
Step-by-step explanation:
a = 4
b= 1
c = 2
d =2
Leftside of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 4 *4 + 8 =16 + 8 = 24
No. of P molecules = 2
Right side of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 2*5 + 2 *7 = 10 + 14 = 24
No. of P molecules = 2
X=7
y=-2
