Answer:
17. D
18. B.
Step-by-step explanation:
m= (y2-y1)/(x2-x1)
m= (5--2)/(-3--2)
m = -7
sub x=-2 ; y = -2
y= mx+c
y= -7x+c
-2=-7x+ c
c= -16
y= -7x-16

Question HelpQuestion 28: Video1
Answer:
88%
Step-by-step explanation:
(73+75+84+x)/4=80
x4 to both sides
73+75+84+x=80x4
73+75+84+x=320
232+x=320
x=320-232
x=88
Answer:
88
Step-by-step explanation:
80*4 = 320 320- (73 + 75 +84 ) = 88 we can cross out 320/80 = 32/8 and 232/320 = 232 /4 (320/4) and divide each side by 4 = 58 / 80 then 29/40 = 40-29 = 11 then decimalise /10 = 1.1 then multiply 80 * 1.1 = 88
problem referred below
Step-by-step explanation:

What is 9 times two thirds
Answer:
6
Step-by-step explanation:
9*2/3=3*2=6 (Cross Cancelling)
Answer: 6
Step-by-step explanation:
So basically, you can figure this out by turning 9 into a fraction, which is [tex]\frac{9}{1}[/tex]. So,
[tex]\frac{9}{1}[/tex] x [tex]\frac{2}{3}[/tex] and multiply it across. So 9 x 2 is 18, and 1 x 3 is 3, so that gets us to [tex]\frac{18}{3}[/tex]. And since this is an improper fraction, we divide 18 by 3 to get 6! Hope this helps! :)
Find the unknown value.
Hello gonzaleznoah570!
[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]
[tex] \large \tt\frac{48}{16} = \frac{ \boxed{}}{8} \\ [/tex]
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Let's take the value inside the box as 'x'. So, now our equation becomes...
[tex] \tt \: \frac{48}{16} = \frac{x}{8} \\ [/tex]
Now, using cross multiplication, solve it.
[tex] \tt \: \frac{48}{16} = \frac{x}{8} \\ \tt \: 48 \times 8 = 16 \times x \\ \tt \: 384 = 16x \\ \tt \frac{384}{16} = x \\ \boxed{\boxed{ \bf \: 24 = x}}[/tex]
The value of the [tex]\boxed{}\\[/tex] is 24.__________________

Hello There!
Question:-
Find the unknown value
Equation Given:-
[tex]\sf \dfrac{48}{16} = \dfrac{\boxed{}}{8} [/tex]
Solution:-
Let's us assume that the value of the unknown number be b.
The Equation would be :-
[tex]\sf \longmapsto \: \dfrac{48}{16} = \dfrac{b}{8} [/tex]
Firstly, Cross multiply :-
[tex]\sf \longmapsto \: (48)*(8)=b*(16)[/tex]
On Simplification of this equation :-
[tex]\sf \longmapsto384 = b*(16)[/tex]
[tex]\sf \longmapsto384 = 16b[/tex]
Overturn The equation given :-
[tex]\sf \longmapsto16b = 384[/tex]
Divide both sides by 16 :-
[tex]\sf \longmapsto \: \dfrac{16b}{16} = \dfrac{384}{16} [/tex]
On Simplification of this equation :-
Cancel 16 and 16, Result is 1b, which equals to b.
[tex]\sf \longmapsto \dfrac{ \cancel{16}b}{ \cancel16} = \dfrac{384}{16} [/tex]
Then cancel 384/16, which results to 24.
[tex]\sf \longmapsto \: b = \cancel\dfrac{384}{16} [/tex]
[tex]\sf \longmapsto \: b = 24[/tex]
Put the value of b (24) on 48/16 = b/8 :-
[tex]\sf \longmapsto \: \dfrac{48}{16} = \dfrac{24}{8} [/tex]
______________________________________
Henceforth,The unknown value is 24.
[tex]\boxed{ \bf \: \dfrac{48}{16} = \dfrac{24}{8} }[/tex]

Question 2
The down payment makes the monthly loan payment fit into Isabel's budget. Besides this benefit, do you
think saving for a down payment on the car was worth it for Isabel? Useeach monthly payment with and
without a down payment) to find the difference of the total amount paid for the car in each scenario to
justify your answer.
Answer:
students should use the monthly payment provided if no down payment is made to find the total amount she'll pay over the course of her loan.
Step-by-step explanation:
Edmentum Financial Math Unit3 Activity on yt 20:58
Answer: Yes, it is worth putting the down payment down as it ends up saving her roughly $865.60.
Step-by-step explanation:
Yes, I think it was worth saving up to put a down payment down. I think this because over time it lowered her interest rate causing her to safe roughly just under a thousand dollars. Without the down payment she would have payed a little under 25 thousand dollars, but with the down payment she is now instead paying a total of just under 24 thousand dollars. I found this out from multiplying the amount she was paying per month based off of if it was with or without a down payment ($412.22 per month without the down payment, and 314.46 per month with the down payment of 5000 dollars) then I would multiply those numbers by 12 and then 5. 12 representing the amount of months per year she is paying and the 5 representing the total amount of years it will take to have it payed off. If it has to be exact though, then the exact dollar amount that the with down payment and without the down payment would be $865.60. That number represents the total she saved when making the down payment after the five years.
If each exterior angle of a regular polygon is 24,how many side does the polygon have?
Answer:
15 sides
Step-by-step explanation:
all exterior angles of any polygon add to 360 degrees
so if you divide 360 by 24, then you will find the number of sides
360/24 = 15
Simplest way to multi-step equations...
Answer: calculator boi
Step-by-step explanation:
Adam leases a car with an upfront payment of $3,069 and monthly payments of $205.
Assuming there are no additional charges, what will be the total cost of a two-year
lease?
Answer:
Total cost of the lease = $7,989
Step-by-step explanation:
12 months = 1 year. So 2 year = 24 months.
Total cost of the lease = (Monthly cost × number of months) + Upfront pay
Total cost of the lease = ( $205 × 24) + $3,069
Total cost of the lease = $4,920 + $3,069
Total cost of the lease = $7,989
Consider the line y = - 5/4 x+7
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
-5/4
4/5
Step-by-step explanation:
Given expression ,
=> y = -5/4x + 7
Comparing to the slope intercept form,
m = -5/4As we know that the slope of two parallel lines is same . So the slope of the line parallel to given line will be -5/4 .
Again we know that the product of slope of two perpendicular lines is-1 . Hence ,
=> m' * -5/4 = -1
=> m = 4/5
Answer:
parallel: -5/4; perpendicular: 4/5
Step-by-step explanation:
parallel lines have the same slope
perpendicular lines have the slope that is the negative reciprocal of the original slope (basically the upside down negative slope)

9514 1404 393
Answer:
B, D
Step-by-step explanation:

What is the slope of a line that passes through points (2,5) and (-6,-3) please help no links either please
Answer:
1
Step-by-step explanation:
if we graph the two points, we can see that the slope rises 8 and runs 8 as well (graph is attached in the picture). this can be written as 8/8, which is equivalent to 1. the y-intercept is 3, so we can write an equation in slope-intercept form. this would be y=1x+3. we can make a table to check this. to find the values in the table, plug the x values (the standard is -2, -1, 0, 1, 2) into the equation. for -2, we would make the equation y=1(-2)+3, which would make y equal to 1. do this for all the other x values.
x - -2, -1, 0, 1, 2
y - 1, 2, 3, 4, 5
to check if this is correct, check if the points are on the graph. they are, so we know that 1 is the slope.

I think its C. It should be.
Answer:
C
Step-by-step explanation:
If you graph y=4x-8, you'll see that
1. The y-intercept is at -8 (where the line intersects the y-axis)
2. The rate of change (or slope) is 4 (for every 1 unit you move to the right, the line goes up 4 units)
The graph shown has a y-intercept at -6, and the slope is 10.
So the function shown on the graph has a greater rate of change (10 vs 8) and a higher y-intercept (-6 vs -8)
In an ice chest there are
10 waters,
6 fruit drinks and 7
sodas. Assume each container is the same size.
If a drink is chosen randomly, then what is the probability that a fruit drink is NOT chosen?
Answer:
17/23
Step-by-step explanation:
total number of drinks = 10+6+7=23
forgetting the 6 fruit drinks
p(no fruit drink is chosen)=(10+7)/23 =17/23

Answer:
2 + 2 + 3 + 3 + (4 x 4 x 5 x 6 x 7 x 8 x 9 x 0) = 10
Step-by-step explanation:
To solve this problem, you would have to multiply zero, which would make your equation 2 + 2 + 3 + 3, therfore 2 + 2 + 3 + 3 = 10.
2 + 2 + 3 + 3 + (4 x 4 x 5 x 6 x 7 x 8 x 9 x 0) ➜ 2 + 2 + 3 + 3 = 10
