If his speed is 43 mph, then it takes him 40/43 of an hour to go 40 miles.
An hour = 60 minutes.
40/43 of 60 minutes = 55.8 minutes. He gets home 55.8 minutes after 6:24 PM.
Answer:
Y=MX+B
Step-by-step explanation:
put -1 on the y axis then go up 4 (3) after that go over 1 to the right since it's positive
Answer:
The zeroes are 2, -2, -6, 5.
Step-by-step explanation:
If 2 of the zeroes are 2 and -2 then (x - 2)(x + 2) is factor of the polynomial.
We can now do long division.
Note (x - 2)(x + 2) = x^2 - 4, so we have:
x^2 - 4 ( x^4 + x^3 - 34x^2 - 4x + 120 ( x^2 + x - 30 <--- Quotient
x^4 - 4x^4
x^3 - 30x^2 - 4x
x^3 -4x
-30x^2 + 120
-30x^2 + 120
x^2 + x - 30 = 0
(x + 6)(x - 5) = 0
x = -6, 5.
Answer:
a = -3 and b = 1
Step-by-step explanation:
x² - 6x + 10
→ Half the second term and place it in the bracket
( x - 3 )²
→ Square -3
- ( 3 )² = -9
→ Place this outside the brackets along with plus 10
( x - 3 ) ² - 9 + 10
→ Simplify
( x - 3 ) ² + 1
