y2-y1/x2-x1

28.5-21/2.5-1 = 5

y=mx+b

21=5(1)+b

21-5= 16

b=16

y=mx+b

y=5(9.5) + 16

klio [65]

Answer: 40.5 square feet

Step-by-step explanation:

Given : Zhi needs new flooring for her two laundry rooms.each room is 4.5 feet long and 4.5 feet wide .

We assume that the room is rectangular in shape .

Area of rectangle = Length x width

Then area of one laundry room = 4.5  feet x 4.5 feet = 20.25 square feet

Area of two laundry room = 2 x 20.25 = 40.5 square feet.

Sam has $440 in $20, $10, and $5 dollar bills. The number of twenties, tens and fives are consecutive integers in this order. Ho
Ludmilka [50]

Answer: There are 12 bills for $20, 13 bills for $10 and 14 bills for $5.

Step-by-step explanation:

Let the number of twenties be x

Let the number of tens be x+1

Let the number of fives be x+2

Amount from twenties will be given as

20\times x=20x

Amount from tens will be given as

10\times (x+1)=10x+10

Amount from fives will be given as

5\times (x+2)=5x+10

According to question,

20x+10x+10+5x+10=440\\\\35x+20=440\\\\35x=440-20\\\\35x=420\\\\x=\frac{420}{35}\\\\x=12

So, there are 12 bills for $20, 13 bills for $10 and 14 bills for $5.

Determine the discriminant for the quadratic equation 0=-2x2+3. Based on the discriminant value, how many real number solutions
nekit [7.7K]

Answer:

Option D.

The discriminat is equal to 24 which

Step-by-step explanation:

The quadratic equation is

-2x² + 3 = 0

Discriminat in quadratic equation tells us the number of solution a quadratic equation has.

For example, the quadratic equation

Ax² + bx + c = 0 will have a discriminat of b² - 4ac.

b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.

In our question, we have -2x² + 3 = 0

A = -2

B = 0

C = 3

b² - 4ac = 0

Substitute the values into the above equation.

0² - 4(-2 ×3) = 0

0 + -4 × -6 = 0

24 = 0

The discriminat of the equation is 24

Which expression is equivalent to 1/4 x + 3 - 1/3 x + (-2) ?
nasty-shy [4]

Answer:

The value of your expression is 7/12x +1.

Step-by-step explanation:

 1/4x + 3 - 1/3x + -2              First, positive and negative is negative

= 1/4x + 3 - 1/3x -2                 Combine like terms, 1/4x and 1/3x

= 7/12x + 3 - 2                          Combine like terms, +3 and -2

= 7/12x +1

Like terms are when a number have similar exponents bases, variables or just plain numbers.

3x, 4x, 5x

1.02x^2, 1.02x^3
