Answer:
d = -1/5c + b
Step-by-step explanation:
1/b - 1/d = 5c
- 1/d = 5c - 1/b
1/d = -5c + 1/b
d = -1/5c + b
For Question 3,
15 ?
__ = ____
120 100
120?=1500
1500/120=12.5
?=12.5%
Question 4
I think it is $462.80
Answer:
Step-by-step explanation:
No. If you reverse the prime number 23, you get 32 and that number is not a prime number.
The general form of the linear equation is:
y = mx + c where:
m is the slope and c is the y intercept
We are given that the slope is equal to -2
Therefore, the equation now becomes:
y = -2x + c
To get the value of the c, we will use the given point (0,0) to substitute in the equation and solve for c as follows:
y = -2x + c
0 = -2(0) + c
c = 0
Based on the above calculations, the equation of the line would be:
y = -2x
The answer is 15 or 3 I think but I'm not sure
