Answers
Answer:
Yes
Step-by-step explanation:
A function has one input (x-value) per output (y-value).
In other words, a relation that does not repeat any x values is a function.
{(3,4) , (5,0) , (2,4) , (-5,-5)}
The domain of the relation is:
{-5,2,3,5}
Since none of the numbers repeat in the domain, the relation is a function.

A curb is 4 inches high. The ramp from the sidewalk yo the street follows the same guidelines as other Ramos (no more than 4.8 degrees, so a 1:12 ratio of vertical to horizontal). What is the horizontal distance for a ramp with a 4 inch vertical distance?
Answers
Answer:
48 inches.Step-by-step explanation:
Givens
The height of a curb is 4 inches. So, the ramp has a height of 4 inches.The ratio between vertical and horizontal distance of the ramp is 1:12.Accoriding to the given ration, one unit of vertical distance is equivalent to 12 units of horizontal distance. So, the horizontal distance is
[tex]h=12(4 \ in)=48 \ in[/tex]
Therefore, the horizontal distance is 48 inches.
The horizontal distance for a ramp with a 4 inch vertical distance will be 48 inches.
Given,
The height of curb is 4 inches.
We have to calculate the horizontal distance for a ramp with a 4 inch vertical distance.
The ramp from the sidewalk of the street follows the same guidelines as other Ramos, no more than 4.8 degree.
Since The ratio of vertical to horizontal is 1:12, it means for a 1 inch vertical distance the horizontal distance is 12 inches.
So, for 4 inches of vertical distance the horizontal distance will be,
[tex]12\times4=48[/tex] inches.
Hence the required horizontal distance is 48 inches.

A construction crew is lengthening a road. The road started with a length of 56 miles, and the crew is adding 4 miles to the road each day.
Let I represent the total length of the road (in miles), and let represent the number of days the crew has worked. Write an equation relating to D. Then use
this equation to find the total length of the road after the crew has worked 39 days.
Answers
Answer:
4d+56=L
4(39)+56=L
L=212
Step-by-step explanation:
4 miles per day added on to the already existing 56 miles equals the total length.
When subbing in 39 for the number of days (or variable "d" in the equation), and following the order of operations, you get 212 miles of road total at the end of the 39 days.

Use the point slope formula
Y2-Y1= m(x2-x1) + b
Answer:
1.) Ans -2 , 14
2.) Ans 2 1/5
3.) Ans y= mx+c
Step-by-step explanation:
first one you use Y = Mx +c
You see the Mx is a multiplication
and you input.
M * x = -5 x 2
M* x = -5 x -1
M* x = -5 x 3
M* x = -5 x -2
and note the answers will be less 4 as the equation states +4 is the y intercept and balances the equation.
So answers of the above in same order are;
-10
5
-15
10
we add 4
-6
9
-11
14
and see that 14 is the correct answer for y.
So the correct coordinates are -2, 14
Question 2) coordinates -1 k can equal = -5x+3
First we write as a division we know the gradient is -5
-we eliminate x
5x-1 / k+3
= 4x/k+3
M = -5
= 4x = -5(k+3)
= 4x = -5k +15
= 4x -15 =-5k
= -11 =-5k
= 11/-5 = k
k = 2 1/5
3) Ans The equation of a line is y=(input the number whatever times the x to make the number before you add)
y = m
3) Ans then you place x next to it
3) Ans then you place + 4 or whatever adds to the number.
So the equation of the line is what makes y its value through m the gradient being the number you times with x and the difference of that total to make y intercept.
Find y intercept and you have c of Mx+c
