Answer:
The only difference between the two equations is that, a linear equation gives a line graph whereas a linear inequality shows the area of the coordinate plane that satisfies the inequality. A linear inequality graph usually uses a borderline to divide the coordinate plane into two regions.

Find the sum of the first 30 terms of the following series, to the nearest integer.
2, 8, 14, ...
Answer:
a= 2
d= 6
n=30
sum= n/2[2a+(n-1)x d]
30/2[ 2x2 + (30-1) x 6]
15 [ 4 +29 x6]

A dinner at a restaurant was advertised at $60.00 plus 18%tax . The total bill for this dinner was.
Answer:
$70.80
Step-by-step explanation:
18%=0.18----Covert the percentage as a decimal
60*0.18=10.80----Multiply the dinner cost by the decimal as tax
$10.80+$60.00=$70.80----Add the last number and the price of the dinner to get your total of $70.80.

A motor cyclist makes a trip of 500km. If he had increased his speed by 10kmh-1, he could have covered 600km in the same time. What was the original speed?
Answer:
the original speed is 50 km/h
Step-by-step explanation:
Let us assume the original speed be x
and fastest speed be (x+ 10)
Now here apply the time formula
i.e. distance by the speed
Original time = Fastest time
500 ÷ x = 600 ÷ x + 10
Now do cross multiplication
600x = 500(x + 10)
600x = 500x + 5000
100x = 5000
x = 50 km/h
Hence, the original speed is 50 km/h
The endpoints of directed line segment PQ have coordinates of P (-7, -5) and Q (5, 3). What are the coordinates of point A, on segment PQ, that divide segment PQ into a ratio of 1:3?
Answer:
(2,1)
Step-by-step explanation:
The coordinate point between two points divided between ratio a and b is expressed as;
(X, Y) = [(ax1+bx2/a+b,ay1+by2/a+b]
Given the coordinate points (-7,-5) and (5,3) divided within the ratio 1:3
X = ax1+bx2/a+b
X = 1(-7)+3(5)/1+3
X = -7+15/4
X = 8/4
X = 3
Similarly
Y = ay1+by2/a+b
Y = 1(-5)+3(3)/1+3
Y = -5+9/4
Y = 4/4
Y = 1
Hence the required coordinate point is (2,1)

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet? Use 3.14 for π
Answer:
The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14
r2=257.5286624
Square root both sides to get radius
r=16 feet
7 feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet
Area of circle:What information do we have?
Area of watering pattern = 907.46 square feet
Area of watering pattern = Area of circle
Area of watering pattern = πr²
907.46 = (3.14)r²
r² = 289
r = 17
Length = 17 feet
