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.

Factorize (4y-5)²+80y
Answer:
16y^2+40y+25
Step-by-step explanation:
[tex] {16y}^{2} + 40y + 25[/tex]
Step-by-step explanation:
(4y−5)^2+80y
Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.
16y^2−40y+25+80y
Combine −40y and 80y to get 40y.
16y^2+40y+25
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

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.

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)

rental cost for each movie and each video game.
X
?
Rental cost for each movie: $[]
Rental cost for each video game: s]
Answer:
video=$6.5
moive=$1
Step-by-step explanation:
5m+2v=18, 3m+8v=55
5m+2v=18
2v=18-5m
v=9-2.5m
plug (v=9-2.5m) in (3m+8v=55)
3m+8v=55
3m+8(9-2.5m)=55
3m+72-20=55
-17m=-17
m=1
plug (m=1) in (v=9-2.5m)
v=9-2.5m
v=9-2.5*1
v=6.5

Write the quadratic equation in standard form: 5x^2-7x-13=-3
Answer:
x=\frac{7+\sqrt{249}}{10},\:x=\frac{7-\sqrt{249}}{10}
Step-by-step explanation:
Answer:
f(x) = 5x^2−7x−10
Step-by-step explanation:
Quadratic equation standard form is f(x) = ax^2 +bx + c . All you had to do was add 3 to both sides of the equation to change this into standard form. :)

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
