Which expression is equivalent to 3(4m - 2) - 2(m + 5)

tangare [24]

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6 -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.

Y=-2x+5 was shifted down 7 units what equation is it now

baherus [9]

Answer:

$y=-2x-2$

Step-by-step explanation:

we have

$y=-2x+5$

This is the equation of a line in slope intercept form

where

$m=-2$ ---> the slope

$b=5$ ----> the y-intercept

we know that

If the given line was shifted down 7 units, then the new y-intercept is equal to

$b=5-7=-2$

The slope of the new line will be the same that the original line, because are parallel lines

The new equation is

$y=-2x-2$

Someone pls pls answer this ill mark u brainliest

Marysya12 [62]

Answer:

$m\angle CBD=35^{\circ}$

Step-by-step explanation:

Since there are $180^{\circ}$ on each side of a line and $\angle ABC$ is marked as a right angle, $m\angle CBE=180-90=90^{\circ}$ .

$m\angle CBE=m\angle DBE+m\angle CBD$ , and $m\angle DBE$ is given as $55^{\circ}$ .

Therefore, we can plug in our values and solve:

$90=55+m\angle CBD,\\m\angle CBD=\fbox{35^{\circ}$}$ .
