Answer:

after 52/3 hours

temparature will be at -151/3

Step-by-step explanation:

y = -2.5x - 7

y = -4x + 19

-2.5x - 7 = -4x + 19

4x - 2.5x = 19 + 7

1.5x = 26

3/2x = 26/1

2/3 x 3/2x = 26/1 x 2/3

x = 52/3

y = -4x + 19

y = -4(52/3) + 19

y = -208/3 + 19

y = -208/3 + 19/1

y = -208/3 + 57/3

y = -151/3

A small restaurant was purchased for 316000 with no down payment and a 6.6% loan for 10 year. Find the monthly payment

DiKsa [7]

We will have the following:

First, we calculate the total payment per year:

$p_y=316000\cdot0.066\Rightarrow p_y=20856$

Now, we calculate the monthly payment:

$316000=\frac{p}{0.0055}(1-\frac{1}{(1+0.066)^{120}})\Rightarrow1738=p(0.9995331951\ldots)$ $\Rightarrow p=\frac{1738}{(1-\frac{1}{(1+0.066)^{120}})}\Rightarrow p=1738.811686$

So, the monthly payment will be approximately $1738.811686.

What is the value of y in the solution to the following system of equations?

NNADVOKAT [17]

y= -32

Step-by-step explanation:

step 1: from the first equation you will make X the subject of formula, the equation then becomes;

X= 4-y

step 2: substitute X in the second equation, the equation then becomes 5 * [4-y] + 3y = -6

[ 2]

step 3: find the LCM and then cross multiply; 20-5y+6y = -6

20+y = -12

y= -12-20

y= -32
