Answer:when x=0; y=18

When x=;6 y=0

When x=3; y=9

Step-by-step explanation:

To complete the table for when x=0, you need to make 'y' subject of the formula.

9x+3y=54

3y=54-9x

Divide both sides by the coefficient of y.

y=(54-9x)÷3

y=18-3x

Therefore, when x=0,

y=18-3(0)

y=18.

When x=3,

y=18-3(3)

y=18-9

y=9

When y=0, you need to make x subject of the formula.

9x+3y=54

9x=54-3y

Divide both sides by 9

x=(54-3y)÷9

x=6-y÷3

When y=0,

x=6-(0)÷3

x=6.

Which of the following is the same as 1.207 x 107?
melisa1 [442]

Answer:

C. Or the third option

Step-by-step explanation:

When you multiply something by a power of ten the decimal moves either left or right by the exponent. That probably sounds really confusing but here are some examples. If you multiply a number by 10^4 the decimal will move right 4 places making the number larger. Meanwhile if you multiplied it by 10^-4  it will move to the left 4 places making the number smaller. In your case, when you multiply 1.207 by 10^7, the decimal moves  places to the right which makes it 12,070,000

A quadratic equation is shown below:
Valentin [98]
Part A)

The given equation is:

25 x^{2} +10x+1=0

The radicand or discriminant(d) of the equation will be:

d=(10)^{2}-4(25)(1) \\  \\ 
d=100-100 \\  \\ 
d=0

Since the discriminant is equal to 0, the given quadratic equation has only 1 root. In other words we can say the the given equation is a perfect square. 


Part B)

The given equation is:

4 x^{2} -4x+1=0

We can solve this expression by factorization. Factors of middle term are to be made in such a way that their product equals the product of first and third term and sum is equal to the middle term i.e. product should be 4x² and sum should be -4x.
So the two such terms are -2x and -2x. Using the factors and simplifying the equation by taking common we get:

4 x^{2} -2x-2x+1=0 \\  \\ 
2x(2x-1)-1(2x-1)=0 \\  \\ 
(2x-1)(2x-1)=0 \\  \\ 
(2x-1) ^{2}=0 \\  \\ 
2x-1=0  \\  \\ 
x= \frac{1}{2}
