cluponka [151]

Answer:

Account 1 yields greater return.

Step-by-step explanation:

Lets solve for the first formula:

A=P(1+\frac{r}{n} )^{nt}

First, change 6.5% into a decimal:

6.5% -> \frac{6.5}{100} -> 0.065

Now, plug in the values for Account 1:

A=3,000(1+\frac{0.065}{2})^{2(10)}

A=5,687.51

<u>Now solve for Account 2:</u>

Change 6% into a decimal:

6% -> \frac{6}{100} -> 0.06

Now plug in the values:

A=3,000e^{0.06(10)}

A=5,466.36

Account 1 yields better money after 10 years.

You are making a recipe that calls for cream of mushroom soup. There is a deal at the store, where you can buy 10 cans of soup f
Olenka [21]

Answer:

The cost of 6 cans of soup =   $7.8

Step-by-step explanation:

The cost of 10 cans of soup = $13

The number of cans needed for the soup = 6

Now, Cost of 1 can of soup =\frac{\textrm{Total cost of 10 cans of soup}}{\textrm{10}}

= $13 / 10 =$1.3

⇒The cost of 1 can of soup is $1.3

Now, The cost of 6 cans of soup  =  6 x   Cost of 1 can

⇒ 6 x $1.3 =  $7.8

Hence, the cost of 6 cans of soup =   $7.8

An easy question all wrong or unhelpful or no-work answers will be reported.
boyakko [2]
Substitution:
2x + (6(1/2x - 6)) = 19
2x + 3x - 36 = 19
5x - 36 = 19
+ 36
5x = 55
÷ 5
x = 11

y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5

Elimination:
y = 1/2x - 6
- y
0 = 1/2x - 6 - y
+ 6
1/2x - y = 6

3x - 6y = 36
2x + 6y = 19
(add)
5x = 55
÷ 5
x = 11

y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5

I hope this helps! Let me know if you need me to explain why I did some things :)

I need help on this aswell
Katena32 [7]

Answer:

Graph C

Step-by-step explanation:

Hi there!

The given linear equations are organized in slope-intercept form: y=mx+b where <em>m</em> is the slope of the line and <em>b</em> is the y-intercept, or the value of y when the line crosses the y-axis.

y = 2x + 4

Here, the <em>b</em> value is 4. Therefore, the y-intercept of this line is 4.

y = -3x - 2

Here, the <em>b</em> value is -2. Therefore, the y-intercept of this line is -2.

To identify the graph that models these equations, we just have to look for the graph where the lines cross the y-axis at 4 and -2.

The only graph that does this is graph C.

I hope this helps!
