Answer:
Range of f(x) = 1/7(9)^x is all real numbers greater than 0.
A. 4y(2y + 5) = 4y(2y) + 4y(5) = 8y² + 20y
B. 7a(3a + 8b) = 7a(3a) + 7a(8b) = 21a² + 56ab
C. 13x³(3y + 2x²) = 13x³(3y) + 13x²(2x²) = 39x³y + 26x⁴ units²
D. 7m²(3m - 5) = 7m²(3m) - 7m²(5) = 21m³ - 35m² units²
Ok done. Thank to me :>
Answer:
6 goldfish = $4.50. You can buy 66 goldfish with $50
Step-by-step explanation:
We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.
To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.
We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.
If this helped, I would appreciate it if you marked me brainliest. Have a nice day!
Answer:
Perpendicular, 1
Step-by-step explanation:
Parallel means the same slope
Perpendicular is the reciprocal and opposite sign
F = (9/5)*c + 32
(9/5)c + 32 = f
(9/5)c = f - 32
9c/5 = (f - 32)
9c = 5*(f - 32)
c = 5*(f - 32) / 9 or c = (5/9)*(f - 32)
I hope this explains it. Cheers.
