Answer:

its b.

Step-by-step explanation: 5n − 19 + n + 7 = 144 − 6n

6n − 12 = 144 − 6n

12n = 156

n = 13

m∠z = (144−6n)°

m∠z = (144−6×13)°

m∠z = 66°

Answer:

$y=10x-170$

Step-by-step explanation:

This problem can be modeled by a linear function, where we have two points (37°C, 200) and (32°C, 150).

Notice that the temperature is the independent variable, because the heartbeat of the cat won't change the temperature, it works in the opposite way.

First, let's find the constant ratio of change.

$m=\frac{150-200}{32-37}=\frac{-50}{-5}=10$

This means the hearbeat of the car changes 10 pulses per minute each 1 celsius degree.

Now, we use the point slope formula to find the equation

$y-y_{1} =m(x-x_{1} )\\y-150=10(x-32)\\y=10x-320+150\\y=10x-170$

Theerefore, the function that represents this situation is

$y=10x-170$

Where $x$ represents temperature and $y$ represents hearbeats.

This is hard for me I need help or my mom is going to be

Harrizon [31]

the answer should be letter A

the difference of 3.4 and 1.25 = 2.15

Now you know that there will be 2 whole blocks and .15 of a block

.15 is equal to 3/20 which is equal to 15/100.

So you will have 2 whole blocks and 15/100 of a blocks. So the answer is A

You have $25,000 to invest. You can find an account (Acount A) that guarantees $925 per year. You also found a simple interest a

Sveta_85 [38]

Account A
A=p+i
A=25,000+(925×5)
A=29,625

Account B
A=p(1+rt)
A=25,000×(1+0.065×5)
A=33,125

How much more did the account B earn
33,125−29,625
=3,500
