Veronica has been saving dimes and quarters. She has 94 coins in all and the total value is $19.30. How many dimes and how many
Stolb23 [73]

Answer:

Step-by-step explanation:

d + q = 94.....d = 94 - q

0.10d + 0.25q = 19.30

0.10(94 - q) + 0.25q = 19.30

9.4 - 0.10q + 0.25q = 19.30

-0.10q + 0.25q = 19.30 - 9.40

0.15q = 9.90

q = 9.90/0.15

q = 66 <===== there are 66 quarters

d + q = 94

d + 66 = 94

d = 94 - 66

d = 28 <==== there are 28 dimes

Nina has some nickels and 9 pennies in her pocket. Her friend, Maurice has twice as many nickels as Nina. Together these coins a
algol13

So Maurice would have 2N nickels  

Total number of coins is N + 2N + 9 = 3N + 9  

Each nickel is 5 pennies  

3N of nickels = 15N pennies  

-----------  

Their worth is 84 cents  

15N + 9 = 84  

15N = 75  

N = 75/15 = 5  

N = 5  


This means Nina has 5 nickels.

Which equation represents the line that passes through (-6, 7) and (-3, 6)?
Degger [83]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

(x_ {1}, y_ {1}): (- 6,7)\\(x_ {2}, y_ {2}): (- 3,6)

We find the slope of the line:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {6-7} {- 3 - (- 6)} = \frac {-1} {-3 + 6} = \frac {-1} {3} = -\frac {1} {3}

Thus, the equation of the line is of the form:

y = - \frac {1} {3} x + b

We substitute one of the points and find b:

6 = - \frac {1} {3} (- 3) + b\\6 = 1 + b\\b = 5

Finally, the equation is:

y = - \frac {1} {3} x + 5

Answer:

y = - \frac {1} {3} x + 5

The function f(x)=5^(x-1) is shown on the coordinate plane. Select from the drop down menus to correctly describe the end behavi
skelet666 [1.2K]

Answer: The end behavior of the given function is,

f(x)\rightarrow 0 as x\rightarrow -\infty

And, f(x)\rightarrow \infty as x\rightarrow \infty

Step-by-step explanation:

Since, by the property of the graph of the exponential function,

If an exponential function is, f(x) = ab^x

If b >1 ( increasing function ) then its end behavior is,

f(x)\rightarrow 0 as x\rightarrow -\infty

And, f(x)\rightarrow \infty as x\rightarrow \infty

While b < 1 ( decreasing function, then its end behavior is,

f(x)\rightarrow \infty as x\rightarrow -\infty

And, f(x)\rightarrow 0 as x\rightarrow \infty

Here, given function is,  f(x)=5^{x-1}

Since 5 > 1

Therefore, the end behavior of the given function is,

f(x)\rightarrow 0 as x\rightarrow -\infty

And, f(x)\rightarrow \infty as x\rightarrow \infty

Which is equivalent to |20|?
Annette [7]

Hey there!

Usually when people are trying to find absolute value we are trying to REMOVE your NEGATIVE in FRONT of your given number and make them almost positive (e.g. 0)

|20| = (positive) 20 because it’s the absolute value of itself ; if your equation was |-20| you would have to say your absolute value would be 20

Answer: |20| = 20 ☑️

Good luck on your assignment and enjoy your day!
