Simplify -5(-5-2+2)-[(3-4) multiplied by 2]

Step2247 [10]

The first step to solving this is to eliminate the opposites.
-5 × (-5) - ((3 - 4) × 2)
Calculate the difference from the expression in the parenthesis.
-5 × (-5) - (-1 × 2)
Multiply the numbers on the left side of the expression
25 - (-1 × 2)
Any expression multiplied by -1 equals the opposite,, which will change the expression to the following:
25 - (-2)
When there is a "-" sign in front of the parenthesis,, you must change the sign of each term in the parenthesis. This rule will make the expression look like the following:
25 + 2
Finally,, add the numbers together to get your final answer.
27
This means that the correct answer to your expression is 27.

Help with this algebra question

choli [55]

If two lines are perpendicular, the slope of one of the lines is the negative reciprocal of the other. Since we know the slope for one of our lines, $2$ m lets find the other:
$m=- \frac{1}{2}$

Now, lets use the point-slope formula to complete the equation of our perpendicular line:
$y-y_{1}=m(x-x_{1})$
$y-5=- \frac{1}{2} (x-2)$
$y-5=- \frac{1}{2}x+1$
$y=- \frac{1}{2} x+6$

We can conclude that our perpendicular line is $y=- \frac{1}{2} x+6$
