Answer:
(- 1, 6 )
Step-by-step explanation:
Equate the right sides of both equations, that is
x² - 2x + 3 = - 6x ← add 6x to both sides
x² + 4x + 3 = 0 ← in standard form
(x + 3)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 1 = 0 ⇒ x = - 1
Substitute these values into f(x) = - 6x
f(- 3) = - 6(- 3) = 18 ⇒ (- 3, 18 )
f(- 1) = - 6(- 1) = 6 ⇒ (- 1, 6 )
Answer:
$12
Step-by-step explanation:
30% is 0.3
So 0.3 × 40 = 12
Answer:
x=65/14
Step-by-step explanation:
(x-10)/(x-4)=50/-6
-50/6=-25/3
(x-10)/(x-4)=-25/3
x-10=-25/3(x-4)
x-10=-25/3x+100/3
x-(-25/3x)=100/3+10
x+25/3x=130/3
28/3x=130/3
x=(130/3)/(28/3)
x=(130/3)(3/28)
x=130/28
x=65/14
Answer:
Option 1
Step-by-step explanation:
-4x+6y-5z=60
for x-int, solve for x when y=0, z=0
-4x+6(0)-5(0)=60
x=-15 (-15, 0,0)
for y-int, solve for y when x=0, z=0
y=10 (0, 10,0)
for z-int, solve for z when x=0, y=0
z=-12 (0, 0,-12)
