Answer:

hf(-3) = -7

Step-by-step explanation:

f(x) = x²

h(x) = 2 - x

To find hf(x), we will substitute f(x) function as x into the h(x) function.

h(x) = 2 - x

hf(x) = 2 - (x)²

hf(x) = 2 - x²

How that we have the hf(x) function, to find hf(-3), we substitute x = -3 into the new function.

hf(x) = 2 - x²

hf(-3) = 2 - (-3)² = 2 - 9 = -7

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for
Phoenix [80]
Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.

Stefan purchases materials to make dog collars. Stefan purchases 10 buckles in a pack and 12 straps in a pack. Stefan doesn't wa
CaHeK987 [17]

Answer:

No

Step-by-step explanation:

Assuming it take 1 buckle and 1 strap per collar, that means we just need to find the lowest common multiple of these 10-pack buckles and 12-pack straps.

For 10: 0, 10, 20, 30, 40, 50, "60", 70, 80, 90, 100...

For 12: 0, 12, 24, 36, 48, "60", 72, 84, 96, 108, 120...

From this, it is obvious that 60 is the lowest common multiple of these two numbers. Therefore, we know that Stefan can make dog collars without having leftover supplies by using 6 10-pack buckles and 5 12-pack straps.

From this, we know that Stefan does not need to buy 120 of either the buckles or the straps.
