Answer:

-4m - 3 , B is your answer

Step-by-step explanation:

-0.25 x 16m = -4m

0.25 x 12 = -3

Whenever you multiply a negative by a positive number you will get a negative number using the negative sign from -3 it would be -4m - 3 or you could also write with its number -4m -3.

Answer:

-4m-3

Step-by-step explanation:

-0.25 times 16 is the same thing as dividing 16 by -4. 16m divided by -4 is -4m

-0.25 times 12 is the same thing as dividing 12 by -4. 12 divided by -4 is -3

What’s the answer for a, and b, and how would you solve it?

xxTIMURxx [149]

Answer:

a) negative

b) -7/6

Step-by-step explanation:

The x value increased, but the y value decreased so the line goes down and has a negative slope

(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line

(4-(-3))/(-1-5)=7/-6

Please help 2х -3y =18

siniylev [52]

Answer:

x = 3(6 + y)/2

Step-by-step explanation:

Solving for x

Add 3y to both sides.

2x = 18 + 3y

Divide both sides by 2.

x = 18 + 3y/2

Factor out the common term 3.

x = 3(6 + y)/2

Which of the following represents 4x^5/6 in radical form

mash [69]

Remember, order of operations
exponent before multiply

so 4x^5/6=4 times x^5/6
simplify the x^5/6 first

remember
$x^\frac{m}{n}=\sqrt[n]{s^m}$

so
$x^\frac{5}{6}=\sqrt[6]{x^5}$

so
$4x^\frac{5}{6}=4\sqrt[6]{x^5}$

Prove that <img src="https://tex.z-dn.net/?f=cos%209x-cos%205x%2Fsin17x-sin3x%3D-sin2x%2Fcos10x" id="TexFormula1" title="cos 9x-

maria [59]

Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) = $\frac{-2sin2x.sin7x}{2sin7x.cos10x}$ = $\frac{-sin2x}{cos10x}$
