How do i solve <br> −4(m+6)=−8
geniusboy [140]

Answer: -4 (m + 6) = -8

We can use the distributive property for the first half of the equation.

-4 × m = -4m    

-4 × 6 = -24

-4m - 24 = -8

Now we add 24 on bothe side sof the equation to get -4m by itself.

-4m - 24 + 24 = -8 + 24

Now we get -4m = 16

Divide -4 on both sides to get m by itself

-4m/-4 = 16/-4 

Simplify and we get m = -4

Find three consecutive integers such that the sum of the largest and 5 times the smallest is -244. URGENT
Bad White [126]

Answer:

-39+5(-41)=244

Step-by-step explanation:

Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)

Five times the smallest means 5x

Sum of the largest and five times the smallest means x+2+5x

This sum is -244 means x+2+5x=-244

Solve this equation

x+2+5x=-244

6x+2=-244

6x=-244-2

6x=-246

x=-41

So, smallest number is -41, second is -40 and largest is -39

= -39+5(-41)=244

Hope this helps, have a nice day/night! :D

Yanka [14]

Answer:

6 units down

Step-by-step explanation:

Transformation is the movement of a point from its original position to a new position. If an object is transformed, all the point making the object is also transformed. There are four different transformations: Reflection, dilation, translation and rotation.

If y = f(x), y = f(x) + k is a translation k units up if k > 0 and is a translation k units down if k < 0

Given that the parent function is an absolute value represented by:

y = |x|

Therefore comparing y = |xl - 6 with y = f(x) + k, k < 0, therefore this is a translation of 6 units down
