Answer:
y = 7x -48
Step-by-step explanation:
Your answer is correct. You just need to write it in the box without the "y =".
__
The 2-point form of the equation for a line is ...
y = (y2 -y1)/(x2 -1x)(x -x1) +y1
y = (8 -(-6))/(8 -6)(x -6) +(-6)
y = 14/2(x -6) -6
y = 7x -42 -6
y = 7x -48
You probably want your answer to look like ...
The in equality is greater then of equal to. > with a line under it.
Answer:
The roots are +/- 5 and +/- 4i or 5, -5, 4i, -4i
Step-by-step explanation:
Begin by dividing through by - 3
-3x^4 / - 3 + 27x^2/-3 + 1200/-3 = 0
x^4 - 9x^2 - 400 = 0 This makes it easier to work with. Substitute
z = x^2
z^2 - 9z - 400 = 0 Factor
(z - 25)(z + 16) = 0 Put the x^2 back in
(x^2 - 25)(x^2 + 16)
======================
Factor x^2 - 25 using the difference of squares.
(x^2 - 25) = (x + 5)(x - 5)
x = +5 and x = - 5
======================
Factor x^2 + 16
x^2 + 16 = 0
x^2 = - 16 Take the square root of x^2 and -16
x = sqrt(-16)
x = +4i, x = - 4i
Answer
The roots are +/- 5 and +/- 4i
Answer:
x > -2
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-9x - 18 = -9 • (x + 2)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by -9
Remember to flip the inequality sign:
Solve Basic Inequality :
2.2 Subtract 2 from both sides
x > -2
Inequality Plot :
2.3 Inequality plot for

Answer:
28.8
Step-by-step explanation:
the original is 45=100%
it reduced by 36% meaning;100%-36%=64%
if45=100%
? =64%
45*64=2880/100=28.8
