Answer:
C 350d>1400
Step-by-step explanation:
You don't add the days to 350 to get the total miles and you don't add the time to 1400 miles. By having 350d the answer would be what times 350=1400 which is why that one is correct. (D= 4)
Answer:
(g · f)(4) = 45
Step-by-step explanation:
f(x)=4x+1
g(x)=x² - 4x- 5
(g · f)(x) = 4(x² - 5) + 1
(g · f)(4) = 4(4² - 5) + 1
Following pemdas
(g · f)(4) = 4(16 - 5) + 1
(g · f)(4) = 4(11) + 1
(g · f)(4) = 44 + 1
(g · f)(4) = 45
Answer:
A. x = 6.08, x = -0.58
Step-by-step explanation:
1. Factor the denominator.
2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.
3. Simplify.
4. Combine like terms.
5. Multiply the right side of the equation by (x-4)/(x-4).
6. Simplify.
7. "Cancel" out the denominators because they are equivalent.
8. Set the equation equal to 0.
Quadratic formula:
9. Factor using the quadratic formula.
10. Multiply and simplify.
11. Plug this into your calculator and solve for x.
The correct answer is A. x = 6.08, x = -0.58.
Answer:
(-5, -8)
Step-by-step explanation:
-3x+3y=-9
-3x+y=7
----------------
simplify -3x+3y=-9 into x-y=3
----------------------------------------
y=x-3
-3x+y=7
------------
-3x+(x-3)=7
-3x+x-3=7
-2x-3=7
-2x=7+3
-2x=10
x=10/-2=-5
y=-5-3=-8
x=-5, y=-8
12.7 rounded to the nearest whole number is 13. =)
