Can u guys answer this and fast (3.610^2)(2.8*10^2)

1 answer:

7 0

so basically we only use the associative property of multiplication and one of the laws of exponents

associative=a(bc)=(ab)c
also law of exponent=a^x times a^y=a^(x+y)

(3.6 times 10^2) times (2.8 times 10^2)
associative
3.6 times 10^3 times 2.8 times 10^2
3.6 times 2.8 times 10^2 times 10^2
law of exponents
10^2 times 10^2=10^(2+2)=10^4
3.6 times 2.8=10.08
the answer is 10.08 times 10^4 or (10.08*10^4) or (1.001*10^5)

the second one


(3.6 times 10^6) times (2.2 times 10^-4)
associative
3.6 times 10^6 times 2.2 times 10^-4
3.6 times 2.2 times 10^6 times 10^-4
law of exponents
10^6 times 10^-4=10^(6-4)=10^2
3.6 times 2.2=7.92
the answer is 7.92 times 10^2 or (7.92*10^2)


A is (1.001*10^5)
 B is (7.92*10^2)

Which coordinate pairs make the equation x-9y=12 true?

asambeis [7]

Answer:

(12,0) and (3, -1) and (0,-4/3)

Step-by-step explanation:

To find if a point makes an equation true, just substitute its x and y values in in the equation and simplify.

1) Let's test the point (12,0). Substitute 12 for x and 0 for y in the equation:

$x-9y=12\\(12)-9(0)=12\\12-0=12\\12=12$

12 does equal 12, so (12,0) makes the equation true.

2) Let's test the point (0, 12). Substitute 0 for x and 12 for y in the equation:

$x-9y=12\\(0)-9(12) = 12\\0-108 = 12\\-108 = 12$

However, -108 does not equal 12, so (0,12) does not make the equation true.

3) Let's test the point (3, -1). Substitute 3 for x and -1 for y in the equation:

$x-9y=12\\(3)-9(-1) = 12\\3 + 9 = 12\\12 = 12$

12 does equal 12, so (3, -1) makes the equation true.

4) Let's test the point (0, -4/3). Substitute 0 for x and -4/3 for y in the equation:

$(0) -9(-\frac{4}{3} ) = 12\\0 + \frac{36}{3} = 12\\0 + 12 = 12 \\12 = 12$

12 does equal 12, so (0, -4/3) makes the equation true.

2) True or False: Absolute value is always negative?|

german

Answer:

True. The absolute value produces a positive value, but then when you negate that value, it would always be negative. What's important is we're not taking the negative of the number being absolute valued itself, but rather we're taking a negative of the result.

Explain why it is usually only necessary to test one point when graphing an inequality

Mars2501 [29]

Because if that point is true than everything on that side of the number line is true. Visa versa.
