The equation will be:
y = -2
Step-by-step explanation:
A horizontal line has no slope as it is parallel to x-axis.
The horizontal line is in the form y = b where b is the y-intercept.
Given
The line passes through (4 -2).
The y-coordinate of the given point is -2 which means that the line will intersect the y-axis on -2
So,
b = -2
and
The equation will be:
y = -2

Answer:
The value of radius r is 50
Step-by-step explanation:
Given as :
The measure of two circles as
Circumference = c Circumference = c'
Diameter = d Diameter = d'
Radius = r Radius = r'
And
= 5
d' = 20
∴ circumference of circle =
=
Or,
=
Or, 5 = 
Or, 5 = 
∴ 2 × r = 5 × 20
I.e r = 50
Hence The value of radius r is 50 Answer
Answer:
<h2>4gallons per minute</h2>
Step-by-step explanation:
Step one:
the unit rate is the amount of water per unit of time
Given data
4/5 gallon to decimal= 0.8gallon
1/5 minute decimal= 0.2 minute
We are told that 0.8 gallons run in 0.2 minute
then x gallon will run in 1 minute
cross muliply we have
x=0.8/0.2
x=4
this means that in one minutes 4gallons will run in the faucet
The unit rate is 4gallons per minute
