How do I round 3.047 to the nearest hundred and show the math

1 answer:

3 0

The second place to the right after the decimal is the hundredth, so basically, to round, you cut off the rest of the decimal places afterwards. If the number after the hundredth is at or above 5, you should make the hundredth 1 higher, but if it is 4 or below, you will just leave it as is. In this case, 3.047 rounds to 3.05. There really is not any math work to show, but just the explanation.<span />

Answer:

x = 1 and y = -2

Step-by-step explanation:

Given that,

2x-3y = 8 ..(1)

4x+3y = -2 ..(2)

Add equation (1) and (2),

2x-3y+4x+3y = 8+(-2)

6x = 6

x = 1

Put the value of x in equation (1).

2-3y = 8

2-8 = 3y

-6 = 3y

y = -2

Hence, the value of x is 1 and that of y is -2.

What are the domain and range of the function x^2-2x^2-4?

jonny [76]

${x}^{2} - 2 {x}^{2} - 4 \\ - {x}^{2} - 4$

The Quadratic Function has the domain as the set of all real numbers.

For the range, start from minimum value to maximum value.

But because the parabola is downward as a < 0. Thus, there are no minimum value but the maximum value instead.

Therefore the range is y <= -4

Which expression is equivalent to the expression shown ? 2 (x + 5) +3 (x2 - 5x +13)

Gnesinka [82]

$\text{Use the distributive property:}\\\\a(b+c)=ab+ac$

$2(x+5)+3(x^2-5x+13)=(2)(x)+(2)(5)+(3)(x^2)-(3)(5x)+(3)(13)\\\\=2x+10+3x^2-15x+39=3x^2-13x+49$

2x+6 - х -4

2x - x = - 4 - 6

x=-10

20x - 8 = 18x +6

20x - 18x = 6 +8

2x = 14

x=7
