Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
13x - 6y = 22
x = y + 6
Step 2: Solve for y
Substitution
Substitute in x: 13(y + 6) - 6y = 22Distribute 13: 13y + 78 - 6y = 22Combine like terms: 7y + 78 = 22Isolate y term: 7y = -56Isolate y: y = -8Step 3: Solve for x
Define original equation: x = y + 6Substitute in y: x = -8 + 6Add: x = -2Larissa takes a dose of 4 drops of medicine every day, three times a day. One milliliter (mL) of the medicine contains about 20 drops. If the medicine comes in a 12 mL bottle, approximately how many days will the bottle last?
Answer:
The bottle will last for 20 days.
Step-by-step explanation:
Given that:
Number of drops in a dose = 4 drops
Dose is taken three times a day, therefore,
Number of drops taken in a day = 4*3 = 12 drops
One milliliter = 20 drops
12 mL = 20*12 = 240 drops
Number of days the bottle will last can be find out by calculating total number of drops by the number of drops consumed in a day.
Number of days bottle will last = [tex]\frac{240}{12}=20[/tex]
Hence,
The bottle will last for 20 days.
Anna has more money than Betty. If Anna gave Betty $200, then they would have the same amount of money. While if Betty gave Anna $220, Anna would then have twice as much as Betty. Calculate the amount of money each girl has using the substitution method
Answer:
Anna has $1460
Betty has $1060
Step-by-step explanation:
let Anna's money be x
and Betty's money be y
If Anna gave Betty $200, then they would have the same amount of money
Anna's money will reduce by 200
x=x-200
Betty's money will increase by 200
y= y+200
if they have the same amount of money, the difference will be zero
x-200=y+200
x-200-y-200=0
x-y-400=0
x-y=400--------------1
this means that Anna has $400 more than Betty
if Betty gave Anna $220, Anna would then have twice as much as Betty.
Betty's money will reduce by 220
y=y-220
Anna's money will increase by 220
x=x+220
Anna's money will double that of Betty's
x+220=2(y-220)
x+220= 2y-440
x=2y-440-220
x=2y-660--------------------2
put x= 2y-660 in eqn 1
(2y-660)-y=400-------------------------1
2y-y=400+660
y= 1060
so Betty has $1060
put y= 1060 in eqn 1
x-y=400
x-1060=400
x=400+1060
x=1460
so Anna has $1460

P(2-r)-17=109 what is the answer
Answer:
126
P = -------------
2 - r
Step-by-step explanation:
Solve for P: P(2-r)-17=109
Combining the constant terms:
P(2 - r) = 126
Dividing both sides by (2 - r) isolates P:
126
P = -------------
2 - r

YALL HELP PLEASE THANK U
Answer:
I am not getting this question
Step-by-step explanation:
Given Vertex (5,4) and focus (8,4)
It can be easily noticed that focus and vertex lie on the same horizontal line y = 4
Obviously, the axis of symmetry is a horizontal line ( a line perpendicular to y-axis). Also, the focus lies to the right of the vertex so the parabola will open up rightward.
(y−k)^2=4a(x−h)
a=8-5=3 as y coordinates are the same.
Since the focus lies to the left of vertex, a = 3
(y−4)^2=4⋅3⋅(x−5)
(y−4)^2=12(x−5)
is the equation of the parabola.

Step-by-step explanation:
Three friends pay 1025 to rent a vacation home. Beth contributed $80 more than danny. Katie contributed $20 less than Beth. How much did Danny contribute?
Answer:
Danny contributed $295
Step-by-step explanation:
Assume that Danny contributed $x
∵ Danny contributed x
∵ Beth contributed $80 more than Danny
→ Add The amount of Danny by $80 to get the amount od Beth
∴ Beth contributed x + 80
∵ Katie contributed $20 less than Beth
→ Subtract the amount of Beth by 20 to get the amount of Katie
∴ Katie contributed x + 80 - 20
∴ Katie contributed x + 60
∵ The three friends pay $1025
→ Add their amounts and equate the sum by 1025
∴ x + x + 80 + x + 60 = 1025
→ Add the like terms in the left side
∵ (x + x + x) + (80 + 60) = 1025
∴ 3x + 140 = 1025
→ Subtract 140 from both sides
∴ 3x + 140 - 140 = 1025 - 140
∴ 3x = 885
→ Divide both sides by 3
∴ x = 295
∵ x represents the amount of Danny contributed
∴ Danny contributed $295

Write an equation, please help
Answer:
y = -6/5x + 2
Answer:
5\6x-2
Step-by-step explanation:
Y=(10-6x)\5
Y= 2-6\5x
Slope of line 1 = -6\5
Slope of line 2*(slope of line 1 )= -1
Slope of line 2 *-6\5=-1
Slopes of line 2 = 5\6
(X-x0)m = y-y0
(X-6)*5\6=y-3
5\6x -5 = y-3
Y= 5\6x -2
