To find the slope of a line that is perpendicular to the given line, we find the negative reciprocal of the given slope (flipped and made negative), so ½ would become -2/1 or simply -2. This gives us the equation y=-2x+b. To find b we plug in the coordinates the new line has to pass through, so ((-5)=-2(10)+b) = (-5=-20+b) = (15=b) or (b=15). So, the answer would be A. y=-2x+15

Which of the following comparisons is FALSE?

dybincka [34]

Answer:

Step-by-step explanation:

Let's check each one-by-one.

we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon

THis is false.

We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.

This is true.

we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.

THis is true.

We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles

So definitely 9 miles IS GREATER than 10 km.

THis is true.

So answer choice A is false, only.

Factor completely 8x5 2x4 4x2. Prime 2(4x5 x4 2x2) 2x(4x4 x3 2x) 2x2(4x3 x2 2).

Alecsey [184]

The complete factor of the expression $\rm 8x^5 + 2x^4 + 4x^2$ is $\rm 2x^{2} (4x^3 + x^2 + 2 )$ correct option is D.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is $\rm 8x^5 + 2x^4 + 4x^2$ .

To solve the expression properly we have to take common (2x²). Then we have

$\rm 8x^5 + 2x^4 + 4x^2\\\\2x^{2} (4x^3 + x^2 + 2 )$

The factor is $\rm 2x^{2} (4x^3 + x^2 + 2 )$ .

More about the factorization link is given below.

Apply the properties of exponents to rewrite each expression in the form kxn, where nn is an integer and x ≠0

professor190 [17]

Answer:

The expression will be $0.333x^{-2}$

Step-by-step explanation:

We have given expression $\frac{x^{-3}x^5}{3x^4}$

We know the property of exponent that when two function are divided then the power of exponent is subtracted and when there is multiplication of two function then exponent is added

So $\frac{x^{-3}x^5}{3x^4}=\frac{x^{2}}{3x^4}=0.333x^{-2}$

So the expression will be $0.333x^{-2}$
