Answer: -12.5

Step-by-step explanation:

x(2y-3) and x=2.5 and y=-1

so you fix in the figures so it will turn to

2.5(-2-3)

so then you open the brackets with 2.5

-5-7.5

Answer: -12.5

What is the equation of this line? y = 2x y=12x y=−2x y=−12x

Anna [14]

Y=2X

Looking at the line you can see that it is moving up from left to right, making it positive. So -2X and -12X are incorrect.

Next we can find the slope by putting rise over run. Chose a point on the line, I’ll use (2,4).
On this point we rise to 4 and run over to 2.
So for rise over run we have 4/2 which is 2.
So y=2x is correct.

Find the x intercepts of the parabola with vertex (4,75) and y intercept (0,27)

user100 [1]

The equation for a parabola with vertex $(h, k)$ is
$y=a(x-h)^{2}+k$

We plug in:
$y=a(x-4)^{2}+75$

We find $a$ by plugging in the point $(0, 27)$ :
$27=a(0-4)^{2}+75$
$\Rightarrow 27=a(-4)^{2}+75$
$\Rightarrow 27=16a+75$
$\Rightarrow 16a=-48$
$\Rightarrow a=-3$

So our equation is
$y=-3(x-4)^{2}+75$

To find x-intercepts, we set $y=0$ :
$-3(x-4)^{2}+75=0$
$\Rightarrow -3(x-4)^{2}=-75$
$\Rightarrow (x-4)^{2}=25$
$\Rightarrow x-4=5, -5$
$\Rightarrow x=9, -1$

So the x-intercepts are 9 and -1.
