Step-by-step explanation:
y - 7 = 3(x - 4)
y - 7 = 3x - 12
y = 3x - 5
The equation of the line in slope intercept form having slope 3 and passing through the point (4, 7) is y = 3x - 5.
What is Slope?Slope of a line is the rise over the run of the given line. It is usually denoted by m.
In other words, Slope of a line can be calculated by finding the difference of the y coordinates divided by the difference of the x coordinates where x coordinate and y coordinate of two points are given.
Equation of a line in slope intercept form is given by
y = mx + c
where, m is the slope and c is the y- intercept.
Now y-intercept is the y-coordinate of the point where x = 0 or when the line touches the Y axis.
Here, m = 3
We have a point (x, y) = (4, 7)
Substituting these values in the equation,
7 = (3 × 4) + c
7 = 12 + c
c = 7 - 12
c = -5
Substituting m = 3 and c = -5,
y = 3x - 5
Hence, the equation of the line passing through the point (4, 7) and with a slope of 3 is y = 3x - 5.

Answer:
$14.00 per pound for A and $12.50 per pound for B and B is offering the better one since it has a lower cost per pound
Step-by-step explanation:
Answer:
Brand A is $14
Brand B is $12.5
Brand B is offering the better value. I know this because when you get the unit rate for Brand A it is $14. When you get the unit rate for Brand B you get $12.5. So You pay less money for Brand B then Brand A.
Step-by-step explanation:
For brand A you need to first divide 70 by 5 which equals to 14
Then you divide 105 by 12 which equals 12.5

if I have 24 coins and 7 pouches how many coins can go in each pouch
Answer:
If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.
Step-by-step explanation:
To solve this you want to divide the 24 coins into 7 pouches.
x = coins
y = pouches
z = how many coins can go in each pouch:
[tex]x/y = z[/tex]
Substitute:
24/7 = z
3.42857142857 = z
round to the nearest hundredth:
3.43 = z
If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.
To figure out how many coins go into each pouch, divide the number of coins by the number of pouches.
Coins per pouch = 24/7 = approx. 3.43

I hope this is good enough:
Answer:
70
Step-by-step explanation:
Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180

What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
To find slop from the given equation,
Slope (m) =
[tex] \frac{ - \: cofficients \: of \: x }{cofficient \: of \: y} [/tex]
So, slope of this equation is - 2
For perpendicular case,
M1 . M2 = - 1
Thus, m2 = 2 ( for this equation)
Similarly,
For parallel case,
M1 = m2
Thus, m2 = - 2 ( for this equation)

Which number produces an irrational number when added to 0.4?
O A. 0.444...
B. 9
C. 3pi
D. 2/7
Answer: C) 3pi
pi is irrational, and so is 3pi
The expression 3pi+0.4 is overall irrational as well.
If x is irrational and y is rational, then x+y is irrational
This is why choice C is the answer.
The other answer choices are rational values which would make the sum rational, so that's why we can rule them out.

The sales tax rate in New Mexico is 8% You buy an Anime coloring book that is $18. What is the final price of the Anime coloring book? Justify how you determined the final price.
Answer: $ 19.44
Step-by-step explanation:
Give : Original price of coloring book = $18
Sales tax = 8% =0.08 [we divide number by 100 to remove %]
Now , the final price of the Anime coloring book = Original price + (Original price) x (Sales tax)
=$ ( 18+18 x 0.08)
= $ (18)(1+0.08)
= $ (18)(1.08)
= $ 19.44
Hence, the final price of the Anime coloring book = $ 19.44
Daniel is looking at two different credit card offers. Credit Card A will give him an APR of 22.45%. Credit Card B will offer will be 1.25% each month. Which the better deal?
Answer:
Credit card B is a better deal
Step-by-step explanation:
in order to compare both credit cards, we must either convert the APR into a monthly rate or the monthly rate to APR.
convert credit card A's APR to monthly rate:
= 22.45% / 12 ≈ 1.87%, which is higher than 1.25%, so credit card B is better
OR
convert credit card B's monthly rate to APR:
= 1.25% x 12 = 15%, which is lower than 22.45%, so credit card B is better
Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.
Answer:
$434.16346
Step-by-step explanation:
Given that :
Gross earning= $14500
Federal, state and local taxes = 11%
0.11 * $14500 = $1595
FICA tax rate = 7.65%
0.0765 * 14500 = $1109.25
Personal deduction :
3.5% * 14500
0.035 * 14500 = $507.50
Total deduction :
$(1595 + 1109.25 + 507.50)
= $3211.75
Net earning : $(14500 - 3211.75) = 11288.25
Since she is paid bi weekly:
Number of biweeks in a year = 52 /2 = 26
Number of payments per annum = 26
Hence,
Net pay per period :
11288.25 / 26
= $434.16346

Sandy sold 22 tickets, which was at least 6 more than twice the number of tickets that Teresa sold. This can be represented by this inequality, where t represents the number of tickets Teresa sold.
Which could be a number of tickets that Teresa sold?
17
11
7
14
Answer:
7
Step-by-step explanation:
Let 'x' represent the number of tickets that Teresa sold, and x is integer and x>=0 (you can not sell negative number of tickets)
6 + 2x < 22
x < 8
The range of possible number of tickets that Teresa sold is {0, 1, 2, 3, 4, 5, 6, 7}.

Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
Answer: Around 1000 students would buy a school lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a school lunch.
what is the parallel slope of 9x - 5y = 4
Answer:
-9x+5y=-4
Step-by-step explanation:
Answer:
m= 9/5
Step-by-step explanation:
Parallel lines have the same slope.
So if you can find the slope of the given line, you have the slope you want.
Change the line into the form
y=mx + c
The value of m
will be the slope of the line.
9x −4 = 5y ← to make the y term positive
y=9/5x − 4/5
m=9/5
