She orders 5 pair in 5 different sizes:
5 x 5 = 25 pair
She orders 3 pair in 3 different sizes:
3 x 3 = 9 pair
Total pairs = 25 + 9 = 34 pair.
Answer:
i might be wrong but i think its 10
Step-by-step explanation:
x2+8x=9
collet terms
10x=9
divide both side by 10
x = 9/10
alternative form
x = 0.9
Answer:
D is wrong its C
Step-by-step explanation:
I just took the test and c was wrong its D and if its neither let me know.
#2: This function is not defined if the denominator = 0. So, steal the denom. and set it = to 0, and then solve the resulting eqn: 3x-1=0, 3x = 1, x = 1/3.
The domain is the set of all real numbers except for x = 1/3. The range is the set of all real numbers except for y = 0.
#4: this function will not be defined if 16-x^4 is less than 0.
so you must solve the inequality x^4 ≤ 16. Take the 4th root of both sides. The domain is (-2, 2). By all means, check. Suppose x = 1.5. is x^4≤16?
The smallest value y can have is zero, which occurs when x = plus or minus 2.
F(10)=300+35(10)
f(10)=300+350
650(10)=300+350
6500
