Answer:

There is 30 2 pt questions and 10 4 pt questions

Step-by-step explanation:

x is number of two-point questions

y is number of four-point questions

There is a total of 100 points.

There is a total of 40 questions.

Now, we solve by substitution

Plug 30 back in to solve for y

(12x^2 + 3x + 6) + (-7x^2 – 4x – 2) = 5x^2 - x + 4

(2x2 – x) + (-x – 2x2 – 2) = -2x - 2

(x3 + x2 + 2) + (x2 – 2 – x3) = 2x^2

(x2 + x) + (x2 + 8x – 2) = 2x^2 + 9x - 2

Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so much!

Anestetic [448]

Answer:

Step-by-step explanation:

Radius =6 ft

Area of circle = πr²

= 3.14 * 6 * 6

= 113.04 ft²

base = 10.39 ft

height = 6+3 = 9 ft

$Area \ of \ triangle = \dfrac{1}{2}*base * height\\\\\\=\dfrac{1}{2}*10.39*9\\$

= 46.76 ft²

Area of the shaded region = area of circle - area of triangle

= 113.04 - 46.76

= 66.28

= 66.3 ft²

What is 6-2p=p+9 ?Because I don't know it

nikklg [1K]

Hey there!

Firstly, you have to $\bold{simplify}$ each of the sides of your equation
$\bold{6-2p-p+9\downarrow}$
$\bold{6+(-2p)=p+9\downarrow}$
$\rightarrow\bold{-2p+6=p+9}$
Now that you have that portion out of the way, we could move on to our second step... which is to $\bold{subtract}$ by the value of $\bold{p}$ on each of your sides
$\bold{-2p+6-p-p+9-p\downarrow}$
$\rightarrow\bold{-3p+6-9}$ (you get this because we solve the particular equation we added above)
Thirdly, you have to $\bold{subtract}$ by the number $\bold{6}$ on each of your sides
$\bold{-3p+6-6=9-6\downarrow}$
$\bold{Cancel:6-6}$ because it equals to $\bold{0}$
$\bold{Keep:9-6}$ because it brings us closer and closer to the answer of $\bold{p}$
Fourthly, we have to $\bold{divide}$ by the number $\bold{-3}$ on each of your sides
$\bold{\frac{-3p}{-3}=\frac{3}{-3}}$
$\boxed{\boxed{\bold{Answer:p=-1}}}$ $\checkmark$

Good luck on your assignment and enjoy your day!
