The larger of two numbers is equal to three times the smaller.if twice the larger is added to three times the smaller, the sum is 27.Find the anwser
Pls help thank you
Answer:
These numbers are 3 and 9Step-by-step explanation:
x - smaller number
3x - three times the smaller number = the larger number
2×3x - twice the targer number
2×3x+3x - twice the larger is added to three times the smaller
2×3x + 3x = 27
6x + 3x = 27
9x = 27
÷9 ÷9
x = 3
3x = 3×3 = 9
Through (1,-4) Slope = -8
A. Rewrite the equation of the line in slope intercept form
B. Identify the slope and y intercept
(Show steps )
Answer:
Rewriting the equation in slope intercept form is: Y= -8x+4
Step-by-step explanation:
Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.
First of all, we know that our slope is -8... so we have y= -8x so far
From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.
To wrap things up, the slope is -8 and the y intercept is 4.
We then get Y= -8x+4
Hope this helps! :)

Answer:
f(4) = -28
Step-by-step explanation:
f(x) = -[tex]x^{2}[/tex] - 6x + 12
f(4) = -[tex]4^{2}[/tex] - 6(4) + 12
f(4) = -16 - 24 + 12
f(4) = -40 + 12
f(4) = -28

A taxi service charges you $1.50 plus $0.60 per minute for a trip to the airport. The distance to the airport is 10 miles, and the total charge is $13.50
How many minutes did the ride to the airport take?
Answer:
20 minutes
Step-by-step explanation:
The question can be shown like so, 1.5+0.6x
Since the total charge was 13.5, you can write an equation
13.5=1.5+0.6x
Simplify using property of subtraction
13.5 - 1.5= 1.5 - 1.5 + 0.6x
12 = 0.6x
Simplify using property of division
12/0.6= 0.6x/0.6
x=20

this fall 126 students participated in the soccer program, while 54 played volleyball. what was the ratio of soccer players to volleyball player?
Answer:
126:54, or
63:27,or
7:3
Step-by-step explanation:
we can see that 126 can be divided by 2, and so can 54, so we reduce to #2,
we can see #2 can be divided by 9, so we get to #3

(a) Find the slope-intercept form of the equation of the line.
Answer:
y=28/3x+6
Step-by-step explanation:
If you use the slope formula, y2-y1
_____\
x2-x1
You would get that the slope is 23/3 and you can see the y-intercept is 6 so you would get y=28/3x+6.
find the line of the equation that passes through (3, -4) and is parallel to 3x + y + 2 = 0
leave your answer in the form of y = mx + c
hi
3x+y +2 = 0 so y = -3x-2
parrallel line has the same slope , so is -3x
then : -3 (3) +c = -4
-9 +c = -4
c = -4 +9
c = 5
so parallel is : y= -3x +5

Answer:
maria : 1/3 =0.3 line on top of three
franco:1/4=0.25
Step-by-step explanation:
tried my best hope its right :)
Answer:
Maria: 1/3 cups for each gallon
Step-by-step explanation:
Maria: 2/3 for every 2 gallons. 2/3:2
Franco: 1 1/4 for every 5 gallons. 1 1/4/:5
Okay, so I'm actually going to do it my way.
Maria : [tex]\frac{2}{3} = 4/6\\\frac{4}{6} /2 =2/6[/tex]
So, I simply turn it into a bigger fraction and cut it in half!
So, Maria uses 1/3 of a cup for each gallon
Hope this will help you figure out Franco's!!!

Mr.Afzal bought an article for Rs4400 for 3years at 8 percent what was the interest charge?
pls solve this question iwill mark as brainlist.
[tex]\large\underline{\underline{\red{\rm\blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]
Here , the given data is :
Principal = Rs 4400 . ( P )Time = 3 years . ( T ) Rate of Internet = 8% . ( R )We can calculate Simple Interest using ,
[tex]\boxed{\purple{\bf Simple\: Interest=\dfrac{P\times\:R\:\times\:T}{100}}}[/tex]
On substituting the respective values ,
⇒ SI = P × R × T / 100.
⇒ SI = Rs 4400 × 8 × 3 / 100 .
⇒ SI = Rs 44 × 8 × 3 .
⇒ SI = Rs 1,056 .
Hence the required Interest is Rs 1,056.
What is the percent of change from 5,000 to 8,000?
Step-by-step explanation:
% change = (new - original)/original × 100
= (8,000 - 5,000)/5,000 × 100
= 3,000/5000 × 100
= 60%
