Answer:
1. y= 3x+1
2. y= -4x+1
3. y=x-10
Step-by-step explanation:
That would be 1/2 r^2 theta where r = radius and theta = angle in radians sp her we have
Area of sector = 1/2 * 4^2 * 2.4 = 8 * 2.4 = 19.2 m^2 Answer
Answer:
-63 > a
Step-by-step explanation:
7 < -1/9a
Multiply each side by -9. Remember to flip the inequality since we are multiplying by a negative
7 * -9 > -1/9 a * -9
-63 > a
This is the concept of algebra, so solve for x we proceed as follows;
4/x-4=x/(x-4)-4/3x
(4-4x)/x=(3x^2-4(x-4))/(3x(x-4))
(4-4x)/x=(3x^2-4x+16)/(3x^2-12x)
cross-multiplying the expression we get:
(4-4x)(3x^2-12x)=x(3x^2-4x+16)
-12x^3+60x^2-48x=3x^3-4x^2+16x
this can be simplified as:
-15x^3+64x^2-64x=0
since the above polynomial is of degree 3, the number of solutions are 3.
