Distribute both numbers from the outside of the parenthesis and multiply that by the the number inside the parenthesis. So 1/2(4x+13) means that you have to multiply 1/2 by 4 and 1/2 by 13. 2x+6.5=6(x+7). On the other side, 6(x+7) do the same thing multiply 6 by x and 6 by 7. 2x+6.5=6x+42 Now thats done, move the "like terms" on the same side. So 2x will move to the other side of the equation while 42 will move the other side of the equation. 4x= -35.5 now divide -35.5 by 4 to find x. -8.875 is what x equals.  I hope this helps you! You can also check if the x your found was correct.

Add 4x²y,-2xy²,-5xy²,3x²y plz explain​
Vinil7 [7]
4x^2 - 2xy^2
5xy^2 +
3x^2y
_____________
12x^5y^4-2xy^2

This is so because 4+5+3 is 12, then using laws of indices to add your x and y you get x^5 and y^4

To simplify your answer to the lowest you have it in the form of
3x^2y^2(4x^2y - 2xy^2)

If you multiply this as well you get the same answer I got with the addition

1. For the function f(x) = x2, Find the slope of the secant line joining (1,f(1)) and
goblinko [34]

The slope of the line connecting two points (<em>a</em>, <em>b</em>) and (<em>c</em>, <em>d</em>) is

(<em>d</em> - <em>b</em>) / (<em>c</em> - <em>a</em>)

i.e. the change in the <em>y</em>-coordinate divided by the change in the <em>x</em>-coordinate. For a function <em>y</em> = <em>f(x)</em>, this slope is the slope of the secant line connecting the two points (<em>a</em>, <em>f(a)</em> ) and (<em>c</em>, <em>f(c)</em> ), and has a value of

(<em>f(c)</em> - <em>f(a)</em> ) / (<em>c</em> - <em>a</em>)

Here, we have

<em>f(x)</em> = <em>x</em> ²

so that

<em>f</em> (1) = 1² = 1

<em>f</em> (1.01) = 1.01² = 1.0201

Then the slope of the secant line is

(1.0201 - 1) / (1.01 - 1) = 0.0201 / 0.01 = 2.01
