You plug in x = 1 and y = -4 into the system of equations and see if they fit:-

y = -4x

- 4 = -4 * 1 = -4         This fits

y = 2x - 2

-4 = 2*1 - 2 = 0   Does NOT fit.

So (1, -4) is not a solution.

A rectangular prism has a length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm. A similar prism has a length of 14.7 cm,
solong [7]
They are each multiplied by a factor of 3.5
You can calculate this by taking the length of the similar prism and divide it with the first prism 14.7/4.2 = 3.5
Do this with the width and height to be sure
20.3/5.8 = 3.5
33.6/9.6 = 3.5

Pension = 12% of salary
nadya68 [22]

Answer:

Salary = $43,313.40

Step-by-step explanation:

Let his salary be x.

Now we're told that;

Pension = 12% of his salary = 0.12x

Health Insurance = 0.3% of salary = 0.003x

Disability Insurance = 0.4% of salary = 0.004x

Since his total contract with benefits is worth $48,814.20

This means that;

x + 0.12x + 0.003x + 0.004x = 48814.2

1.127x = 48814.2

x = 48814.2/1.127

x = $43,313.40

What is the domain of y = cos ^-1x?
Bas_tet [7]

Answer:

Step-by-step explanation:

Correct option is

D

[1,(1+π)  

2

]

f(x)=(1+sec  

−1

(x))(1+cos  

−1

(x))

Here the limiting component is cos  

−1

(x), since the domain of cos  

−1

(x) is [−1,1].

Therefore,

f(1)=(1+0)(1+0)

=1

f(−1)=(1+π)(1+π)

=(1+π)  

2

 

Hence range of f(x)=[1,(1+π)
