Answer:
10 + 2^3 * 4-1 = 41
Step-by-step explanation:
You just have to use PEMDAS.
First you see there are no parenthesis.
So you start with exponents, 2^3 = 8.
Then you do multiplication, 8 * 4 = 32.
Then you see there is no division.
So you move to addition, 10 + 32 = 42.
Then you go to subtraction, 42 - 1 = 41.
Hope this helps.

Solving quadratic equations</h3>
Quadratic equations are equations that has a leading degree of 2. Given the following functions:
f(x)=2x^(2)-3x-10
g(x)=-3x^(2)+20
To solve, we will use the quadratic formula as shown below;
For the quadratic equation f(x)=2x^(2)-3x-10
a = 2
b = -3
c = -10
Substitute
For the quadratic equation -3x² + 20
a =-3
b = 0
c = 20

Answer:
y=-3
Step-by-step explanation:
"varying directly" means there is only a factor between x and y, i.e.:
y = k·x
so k = y/x = -1/3
so if x=9, y = -1/3·9 = -3
