For all of these you're trying to solve for the variable. The variable is usually a number or symbol.

11) -44+n=36
Step one would be to add 44 to both sides of the equation.

N=80

12) -36=p-91
Step one would be to add -91 to both sides of the equation.

P=55

13) X-225=671
Step one you be to add 225 to both sides of the equation. Although it may seem difficult because of the big numbers, it's the same technique.

14) 19=c-(-12)
Step one on this equation will be a little different. Because there are two negative signs (-), they turn into a plus sign. Remember, two negative signs make a positive sign.

19=c+12

Now you just subtract 12 from each side of the equation.

6=C

[HELP FAST] A line passes through the point (4, -9) and has a slope of -5/4

DENIUS [597]

Answer:

$y= \frac{-5}{4}x -4$

Step-by-step explanation:

using pt-slope form, we get $y - (-9) = \frac{-5}{4}(x-4)$ . Using the Distributive Property and Addition Propert of Equality, we can simplify this equation into $y = \frac{-5}{4}x + 5$ by factoring -5/4 into (x-4) and subtracting 9 from both sides.

How would I go about solving this?

garik1379 [7]

If you draw more of those triangles, there will be 6 that can fit, so find area of 1 triangle and multiply it by 6. Write that number down and then do Pi r squared to find the area of the circle, then do circle area minus triangles area when you get that, divide it by 6. That is the area of the white region so then do Pi R squared again and then subtract the white area from that

If f(x)=×^2+7x-5 and you divide by x-2, What is the quotient and remainder?

katrin [286]

Answer:

The quotient is : x+9

The remainder is : 13

Step-by-step explanation:

The question requires you to perform the long division method;

This will be;

$x-2\sqrt{x^2+7x-5}$

start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;

x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x

- x²-2x+0 ------------perform subtraction of like terms

---------------------

9x-5 ----now divide this answer by x-2 ,starting with x and 9x

----------------------This will give , 9 then multiply 9 by x-2 to get 9x-18 and perform the subtraction operation as;

9x-5

- 9x-18

------------------------

So the answer will be; x+9 remainder 13
