You could create a equation such below:

y= 50x+20

Next, put 12 in both y=50x+20 and y=15x+80

Then, y=50x+20=50 · 12+ 20=600+20= 620

           y=15x+80=15 · 12+ 80=180+80= 260

 

Compare these two, it's clearly that the second one is cheaper


Answer: The camera in the second store is cheaper.

Workout the value for 3x^2-5y
ale4655 [162]
Remember to do PEMDAS so your answer is not correct, since you multiplied before doing the parentheses/exponents.

Explanation:
3(3)^2- 5(4)
= 3(9) - 5(4)
= 27 - 20 = 7

Please help me out please
Ksivusya [100]

By comparing the perimeters, we can deduce the scaling factor:

k = \dfrac{34}{20} = 1.7

The areas scale with the square of the scaling factor, so the new area is

19.6 \cdot 1.7^2 = 56.644

I really need help with 15 and 16 please
Mandarinka [93]

Answer:

  15. 50 kg

  16a. 5 kg

  16b. 3.75 kg

Step-by-step explanation:

The formula relating force, mass, and acceleration can be solved for mass. This formula will apply to both problems. We'll use m for both "mass" and "meters". We presume you can avoid getting mixed up by understanding that meters is used in the context of acceleration: m/s².

  F = ma

  m = F/a . . . . . divide by a

__

15. m = (250 N)/(5 m/s²) = 50 kg

__

16a. m = (15 N)/(3 m/s²) = 5 kg

16b. m = (15 N)/(4 m/s²) = 3.75 kg

_____

<em>Comment on units</em>

Especially for physics problems, I like to keep the units with the numbers. It is helpful to remember that Newtons are equivalent to kg·m/s². So, dividing Newtons by acceleration in m/s² will give mass in kg. Since you're familiar with F=ma, it's not too hard to remember that the units of force (N) are the product of the units of mass (kg) and acceleration (m/s²).
