The picture is my problem.

Sidana [21]

Answer:

Step-by-step explanation:

Your line has the wrong slope. Its slope is ½, but the equation tells you that the slope is ¾.

The point (0,2) is correct, but (-4,0) is incorrect. If x=-4 then y=-1, not 0.

Plot (-4,-1), then draw the line passing through (-4,-1) and (0,2).

Use the quadratic formula to solve the equation x^2-7x-6=0

olganol [36]

Answer:

$\frac{7\pm\sqrt{73}} {2}$

Explanation:

We have been given with the quadratic equation $x^2-7x-6=0$

We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

$D=b^{2}-4ac$

and after that to find the variable suppose x we have the formula

$x=\frac{-b\pm\sqrt{D}} {2a}$

And general quadratic equation is

$ax^2+bx+c=0$

On comparing the given quadratic equation with genral quadratic equation we will have values

a=1, b=-7 and c=-6

After substituting these values in the formula we will get

$D=(-7)^2-4(1)(-6)={73}$

After substituting in the formula to find x we will get

$\frac{-(-7)\pm\sqrt{73}} {2}= \frac{7\pm\sqrt{73}} {2}$

Calculate the perimeter of a rectangle which is 11 metres long and 4 metres wide

mote1985 [20]

To calculate the perimeter of a rectangle what you would do is add the parallel sides together so 11+11=22 and then 4+4=8 so we would add 22+8=30

So your answer would be 30
(correct me if im wrong)
