Answer:
[tex]y = - \frac{1}{3} x + 2[/tex]
Step-by-step explanation:
Slope-intercept form
y= mx +c, where m is the slope and c is the y-intercept.
y= 3x +4
Since the given equation is already in the slope-intercept form, we can easily identify the slope of this line by looking at the coefficient of x.
slope= 3
The product of the slopes of perpendicular lines is -1. Let the slope of the perpendicular line be m.
m(3)= -1
Divide both sides by 3:
m= -⅓
y= -⅓x +c
Since the question does not specify the points the perpendicular line passes through, c can be any integer.
Thus, the equation of the perpendicular line could be y= -⅓x +2.

Mei Mei finds some dimes and quarters in her change purse. How much money (in dollars) does she have if she has 7 dimes and 12 quarters? How much money (in dollars) does she have if she has xx dimes and yy quarters?
Answer:
$3.70
Step-by-step explanation:
4 quaters= 1$
4=1
8=2
12=3
7 dimes =70
so there for
$3.70
Answer:
$3. 70
Step-by-step explanation:
Each dime equals 10 cents. There are 7 dimes. 10+10+10+10=10+10+10= 70
Each quarter equals 25 cents. add 25, 12 times, 25,25,25,25,25,25,25,25,25,25,25,25=300. Just add a decimal.

which is the better but?A dozen eggs for $2.50 or one egg at a time on sale for $0.20 each
pls help
Answer:
single egg
Step-by-step explanation:
0.20 x 12 = 2.40
regular = 2.50
Answer:
one egg a time
Step-by-step explanation:
We know a dozen eggs consists of 6eggs and in total it costs $2.50
Now 1 egg is $0.20 when you buy 5 more eggs separately it gives you a total amount of $1.25 so you save more money when you buy one egg at a time

My question is in the picture, I WILL GIVE BRAINLIEST AND YOUR GETTING REWARDED 50 POINTS.
Answer:
The form for a point-slope equation is y-y1=m(x-x1), where ”m” is the slope and (x1,y1) is a point on the graph. Substituting in the slope and point, the equation is y+7=-4(x-2).

School rules permit no fewer than 2 teachers per 25 students. There are at least 245 students enrolled in the school. If x represent teachers and y represents students, which system of linear inequalities can be used to determine the possible number of teachers and students at the school?
2y ≥ 25x and y ≥ 245
2y ≤ 25x and y ≥ 245
25y ≤ 2x and y ≥ 245
25y ≥ 2x and y ≥ 245
Answer:
(b) 2y ≤ 25x and y ≥ 245
Step-by-step explanation:
You want the teacher/student ratio to be at least 2/25, so ...
x/y ≥ 2/25
25x ≥ 2y . . . . . multiply by 25y
2y ≤ 25x . . . . . swap sides to get the form used in answer choice B
The other inequality says the number of students is at least 245:
y ≥ 245
Answer:
B- 2y ≤ 25x and y ≥ 245

(-2,2) reflected in the line y=-1
Answer:
(-2,-4)
Step-by-step explanation:
Graph it and you would find that (-2,2) is 3 units higher than the line y=-1. So you would reflect it across by starting at (-2,-1) and count downwards, 3 to get (-2,-4).

Q1. For each of the following values of a,b and c, where
(a) a = -20, b = -10, c = 5
(b) a = -40, b = 10, c = -5
Show that:
(i) a÷b ≠ b÷a
(ii) (a÷b)÷c ≠ a÷(b÷c)
(iii) a÷(b+c)≠(a÷b)+(a÷c)
Explanation:-
⟨a⟩Given that
a = -20
b = -10
c = 5
⟨i⟩ LHS = a÷b
⇛ -20÷-10
⇛ -20/-10
⇛ 2
and
RHS = b÷a
⇛ -10÷-20
⇛ -10/-20
⇛ 1/2
LHS ≠ RHS
a÷b ≠ b÷a
⟨ii⟩
LHS = (a÷b)÷c
⇛ (-20÷-10)÷5
⇛ 2÷5
⇛ 2/5
RHS = a÷(b÷c)
⇛ -20÷(-10÷5)
⇛ -20÷-2
⇛ -20/-2
⇛ 10
LHS ≠ RHS
(a÷b)÷c ≠ a÷(b÷c)
⟨iii⟩ LHS = a÷(b+c)
⇛ -20÷(-10+5)
⇛ -20÷(-5)
⇛ -20/-5
⇛ 4
RHS = (a÷b)+(a÷c)
⇛ (-20÷-10)+(-20÷5)
⇛ 2+(-4)
⇛ 2-4
⇛ -2
LHS ≠ RHS
a÷(b+c) ≠ (a÷b)+(a÷c)
⟨b⟩.Given that
a = -40
b = 10
c = -5
⟨i⟩ LHS = a÷b
⇛ -40÷1
⇛ -40/1
⇛-40
and
RHS = b÷a
⇛ 10÷-40
⇛ 10/-40
⇛ -1/4
LHS ≠ RHS
a÷b ≠ b÷a
⟨ii⟩.
LHS = (a÷b)÷c
⇛ (-40÷10)÷-5
⇛ -4÷-5
⇛ 4/5
RHS = a÷(b÷c)
⇛ -40÷(10÷-5)
⇛ -40÷-2
⇛ -40/-2
⇛ 20
LHS ≠ RHS
(a÷b)÷c ≠ a÷(b÷c)
⟨iii⟩ LHS = a÷(b+c)
⇛ -40÷(10-5)
⇛ -40÷(5)
⇛ -40/5
⇛ -8
RHS = (a÷b)+(a÷c)
⇛ (-40÷10)+(-40÷-5)
⇛ (-4)+8
⇛ 8-4
⇛ 4
LHS ≠ RHS
a÷(b+c) ≠ (a÷b)+(a÷c)

12=2(7x + 8)
Step-by-step explanation:
2(7x +8)=12
2(7x +8)/2 =12/2
7x +8 =6
7x=6-8
7x = -2
x= -2/7
Hi there! :)
12=2(7x+8)
Use the Distributive property:
12=14x+16
Move all the numbers to the right side and the variables to the left side:
-14x=16-12
-14x=4
Divide both sides by -14 to isolate x:
x=[tex]-\frac{4}{14} \\-\frac{2}{7}[/tex]
Therefore, x=[tex]-\frac{2}{7}[/tex]Hope this helps you!

The following ratio gives us a unit rate of 2 feet per second.
Fill in the missing number in the ratio.
?/10 foot : 1/4 second
Step-by-step explanation:
2 ft / 1 second
and now
x/10 foot / 1/4 second
we need to multiply the original ratio by 1/4 to get the same denominator :
2/1 × (1/4)/(1/4) = (2/4) / (1/4) = (1/2) / (1/4)
how many 10th foot are 1/2 ?
we need to bring 1/2 to the denominator of 10.
1/2 = x/10
10 = 2x
x = 5
so, 1/2 = 5/10
therefore, or answer is
5/10 foot / 1/4 second
Pierre's unicycle wheel has a diameter of 80 cm.
a) How far does the unicycle move if the
wheel turns once?
Give your answer in metres, correct
to 2 decimal places.
b) Pierre enters a 100 m unicycle race.
How many times must the wheel rotate
completely in order for Pierre to
travel 100 m?
Give your answer to the nearest
whole number.
Answer:
a) 251.33 cm
b) 40 times
Step-by-step explanation:
C = d x r
a) C = 80 cm x 3.14 = 251.33 cm
b) 100 m = 10,000 cm
10,000cm/251.33cm = 40 times

what statement makes the open sentence 12 + 3x = 30 true?MUTIPLE CHOICE QUESTION WILL MARK BRAINLIEST
(x=2), (x=4), (x=5), (x=6)
Answer:
x= 6
Step-by-step explanation:
12+3x=30
3x+12=30
3x+12-12=30-12
3x=30-12
3x=18
3x divided by 3 = 18 divided by 3
x=18 over 3
18 divided by 3 is 6
x=6
Answer:
x = 6
Step-by-step explanation:
12 +3x = 30
Subtract 12 from both sides
3x = 30 - 12
3x = 18
Divide both side by 3
x = 18/3
x = 6

3)-3(v + 25) = 111
Use distributive property
-3v + (-3)*25 = 111
-3v - 75 = 111
Add 75 to both sides
-3v = 111+ 75
-3v = 186
Divide both sides by (-3)
v = 186/(-3)
v = -62
