The sum of five times a number and four is equal to negative eleven. What is the number?

n=-3

Step-by-step explanation:

Move all terms that don't contain  n  to the right side and solve.

Write out he equation as 5n+4=-11.

-3

Step-by-step explanation:

Create a formula:

-11=5x+4

Now we simplify the equation to get x all alone:

Subtract 4 from both sides:

-15=5x

Divide both sides by 5:

-3=x

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
