Answer:

x = -2

Step-by-step explanation:

<em>To solve for variables, we need the equation to be set equal to something. If no other number is given, assume zero.</em>

2x + 4 = 0

<em>Move </em><em>4</em><em> to the right by subtracting it from the left and right (since it is being added).</em>

2x = -4

<em>Next, isolate </em><em>x</em><em> by dividing both sides by </em><em>2</em><em> (since </em><em>x</em><em> is being multiplied by </em><em>2</em><em>)</em>

x = -2

<em>We can check that this is correct by plugging in </em><em>-2</em><em> for </em><em>x</em><em> and seeing if we get </em><em>zero</em><em>.</em>

2(-2) + 4 = 0

-4 + 4 = 0

0 = 0

19x+15y=-6 changed into slope intercept form.
attashe74 [19]

Answer:

y = - \frac{19}{15} x - \frac{2}{5}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

19x + 15y = - 6 ( subtract 19x from both sides )

15y = - 19x - 6 ( divide all terms by 15 )

y = - \frac{19}{15} x - \frac{6}{15}, that is

y = - \frac{19}{15} x - \frac{2}{5} ← in slope- intercept form

the expression 16t^2 models the distance in feet that an object falls during t seconds after being dropped. what distance will a
Yuri [45]
<span>In this expression, the variable ’t’ stands in for any possible value of seconds. Therefore, since you know how long it takes the object to fall in seconds, you can put this into the expression. 16 x (4^2) = 256. The distance is 256ft.</span>

The equation of line a is y=3/4x-3 If line b runs parallel to line a and passes
katen-ka-za [31]

Answer:

y = -4/3 x - 1/3

Step-by-step explanation:

y = -4/3 x + b

5 = -4/3 (-4) + b

15 = 16 + 3b

b = -1/3

y = -4/3 x - 1/3

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

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

                     13

So the answer will be; x+9 remainder 13
