-25/8 minus 5/2
(You just turn them into improper fractions)
Volgvan3 years ago
4 0

Answer:

-5 5/8

Step-by-step explanation:

A negative minus a positive is essentially a negative plus a negative! The two values will add on top of each other to create a larger negative number.

I'd recommend turning the mixed numbers into improper fractions: 25/8 and 5/2. Then, make sure their denominators are equal by multiplying 5/2 by a "big one" or 4/4. This should get you 20/8.

Now, solve for -25/8 - 20/8 to get -45/8. Turn that number into a mixed number, and you have your answer!

Write the equation for a circle that satisfies the given conditions.
Alisiya [41]

The standard form of a circle is:

(x-a)^2+(y-b)^2=r^2

Your center is (-10,  -6) and your radius is 9

Plug them into the equation and you get

(x-(-10))+(y-(-6)) = 9^2

(x+10)^2 + (y+6)^2=81

The correct answer is D.

Please help me <br>find f(x+h)​
Kay [80]

Answer:

f(x) = -2x+5

f(x+h) = -2x -2h +5

g(x) = -4x-2

g(x+h) = -4x -4h -2

h(x) = 4x^2+1

h(x+h) = 4(x+h)^2 +1 = 4x^2 +8xh + 4h^2 +1

Q(x) = -3x^2 +4

Q(x+h) = -3(x+h)^2 +4 = -3x^2 -3h^2 -6xh + 4
