.
Carlos’s Work




14(49)


Step 1

14(40 + 9)


Step 2

14(40) + 9


Step 3

560 + 9


Step 4

569



What was the first error that Carlos made?


Step 1 should have been 14(7 + 7).

Step 2 should have been 14(40) + 14(9).

Step 3 should have been 23(40).

Step 4 should have been 5,040.

Bob ate 10 carrots and 7 hershey's kisses and the total calories were 263. fred ate 4 carrots and 8 hershey's kisses and the tot
Zarrin [17]
Two equations 

let c the calories in carrot
let h the  <span>calories in </span><span>hershey's kisses
</span><span>

4c + 8h = 230                eq 1</span>
10 c + 7 h = 263             eq 2  


to solve the solution  we multiply eq  1 by 10 
we multiply <span>eq  2 by 4
</span>
40 c + 80 h =  2300
40c + 28 h = 1052 

we subtract the two equations we get
 52  h = 1248 

h= 24 

and so in replacing h = 24 in the equation we get c = 9.5

What does g(n) equal
NikAS [45]
We are given the function: 
g(n) = 3 (\frac{7}{5} )^n

We need to find what g(-3) equals. 

What the question is asking is what is the resulting value after you plug in -3 as n to the function. Meaning you replace the n that is in the function with -3. 

g(-3) = 3( \frac{7}{5})^{-3}

Remember back to the order of operations. 

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

For this problem we can keep the fraction as it is (unless you are permitted to use a calculator... if that is the case then just plug all that into a calculator) and keep going to the exponent. 

Negative exponents make fractions FLIP. So our fraction will look like this: (\frac{7}{5})^{-3} =  (\frac{5}{7})^{3}

Now that we have it without the negative exponent we need to distribute the cubed power to each number in the fraction (which is essentially the same as saying this: \frac{5}{7}* \frac{5}{7}* \frac{5}{7})

\frac{5^{3}}{7^{3}} =  \frac{125}{343}

We ARE NOT done! We still have this left: 
g(-3) = 3 \frac{125}{343}
Multiplying by 3 you get the following: 

\frac{375}{343}

So what does g(-3) equal? This right here: 

\frac{375}{343}

39. State the equation for the line described below.
devlian [24]

Answer:

Step-by-step explanation:

39). y = -\frac{7}{8} x + 3

40). m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m( x - x_{1} )

(- 7, 5)

( - 12, 4)

m = ( 4 - 5 ) / ( - 12 + 7) = 1/5

y - 5 = (1/5)(x + 7) ⇒ y = \frac{1}{5} x + 6.4
