write an equation in point slope form for the line through the given point with the given slope (-4, -3); m=8
Answer:
An equation in point-slope form for the line will be:
[tex]y - (-3) = 8 (x - (-4))[/tex]
Please check the attached line graph also.
Step-by-step explanation:
Given
The point (-4, -3)
The slope m = 8
To determine
Write an equation in point slope form for the line.
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case,
(x₁, y₁) = (-4, -3)The slope m = 8substituting the values m = 8 and the point (-4, -3)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-3) = 8 (x - (-4))[/tex]
Therefore, an equation in point-slope form for the line will be:
[tex]y - (-3) = 8 (x - (-4))[/tex]
Please check the attached line graph also.

a piggy bank has $6.95 and contains only nickles and dimes. If there are a total of 91 coins, how many nickles are there
Answer:
There are 43 nickels in the piggy bank.
Step-by-step explanation:
Given that:
Number of coins = 91
Worth of coins = $6.95 = 6.95*100 = 695 cents
Let,
x be the number of nickles
y be the number of dimes
According to given statement;
x+y=91 Eqn 1
5x+10y=695 Eqn 2
Multiplying Eqn 1 by 5
5x+5y = 455 Eqn 3
Subtracting Eqn 3 from Eqn 2
(5x+10y)-(5x+5y)=695-455
5x+10y-5x-5y=240
5y = 240
[tex]\frac{5y}{5}=\frac{240}{5}[/tex]
y = 48
Putting y=48 in Eqn 1
x+48=91
x=91-48
x= 43
Hence,
There are 43 nickels in the piggy bank.

and 3,240 books total.
How many books does
each shelf hold?
Answer:
60
Step-by-step explanation:
Assuming that all 54 shelves hold the same number of books its just a matter of dividing them (or sharing them equally) on each shelf.
3240 / 54 = 60
Each shelf holds 60 books.

Step-by-step explanation:
We essentially have x = 180 and a+b+c = x.
So we are just substituting x for a+b+c
A mix of 32 quarters and dimes totals $6.35. Find the system of equations that would help you answer the question and then find how many quarters (x) and dimes (y) you would have?
Answer:
21 quarters and 11 dimes = 32 coins
Step-by-step explanation:
x + y = 32
0.25x + 0.10y = 6.35 [take the first equation and make it equal to x]
x = 32 - y [now take this equation and plug it in the above]
0.25 (32-y) + 0.10y = 6.35
8 - 0.25y + 0.10y = 6.35
8 - 0.15y = 6.35 [subtract 8 from both sides]
-0.15y = -1.65 [divide by -0.15 to isolate y]
y = 11 so there are 11 dimes
plug it into the first equation: x + 11 = 32; x = 21 so there are 21 quarters

One day, her son asked her how fast Buzz could fly. Jean, knowing that Buzz is really an airplane, told him about 500 miles per hour. How many feet per second can Buzz travel? Show your work, friends.
Answer:
The Buzz can travel 733.33 feet per second.
Step-by-step explanation:
An hour has 60 minutes, each of which has 60 seconds. So one hour has 60*60 = 3600 seconds.
The airplane can fly 500 miles per hour. Each mile has 5280 feet. So the plane can fly 500*5280 = 2640000 feet in one hour.
Per second, we have:
[tex]\frac{2640000}{3600} = 733.33[/tex]
The Buzz can travel 733.33 feet per second.

Associative Property of Addition
Commutative Property of Addition
Commutative Property of Multiplication
Identity Property of Multiplication
Multiplicative Property of Zero
Associative Property of Multiplication
Distributive Property
Answer:
Step-by-step explanation:
This is a help site, so I'll explain each property and see if you can match them yourself.
Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.
Commutative Property of Addition - same as the associative property but with 2 numbers.
Identity Property of Multiplication - Any number multiplied by one is itself
Multiplicative Property of Zero: x * 0 = 0
Associative Property of Multiplication - Same as that of addition, yet with multiplication.
Distributive Property: Factoring Out.

rate
Which account would you suggest for Natalie? Continuously
9514 1404 393
Answer:
3.65% monthly
Step-by-step explanation:
The same amount is invested for the same period in all accounts, so we only need to determine the effective annual rate in order to compare the accounts.
For compounding annual rate r n times per year, the effective annual rate is ...
(1 +r/n)^n -1
For the same rate r, larger values of n cause effective rate to be higher. As a consequence, we know that 3.65% compounded quarterly will not have as great a yield as 3.65% compounded monthly. The effective rate for the monthly compounding is ...
(1 +0.0365/12)^12 -1 = 3.712%
The effective rate for continuous compounding is ...
e^r -1
For a continuously compounded rate of 3.6%, the effective annual rate is ...
e^0.036 -1 = 3.666%
This tells us the best yield is in the account bearing 3.65% compounded monthly.
_____
If i is the effective annual rate of interest as computed by the methods above, then the 10-year account balance will be ...

Are the equations y – 5 = 2(x – 1)and y - 3 = 2(x + 3) the same equation? Explain
Answer:
No.

y - 5 = 2(x - 1)
y = 2x + 3
y - 3 = 2(x + 3)
y = 2x + 9

The scholastic assessment test is standardized to be normally distributed with a mean μ=500 and a standard deviation σ=100. What percentage of SAT scores falls
a. between 500 and 600
b. between 400 and 600
c. between 500 and 700
d. between 300 and 700
e. above 600
f. below 300
Answer:
68.27%.
Step-by-step explanation:
Here we have [tex]\mu=500,\sigma=100[/tex]
Let X shows the SAT score. z-score for X=400 is
[tex]z=\frac{X-\mu}{\sigma}=\frac{400-500}{100}= -1[/tex]
z-score for X=600 is
[tex]z=\frac{X-\mu}{\sigma}=\frac{600-500}{100}=1[/tex]
So the proportion of SAT scores falls between 400 and 600 is
[tex]P(400<X<600)=P(-1<z<1)=0.6827[/tex]
hence, required percentage is 68.27%.
one can use the same method to find the% for all other cases as
well.
