Step-by-step explanation:
f(x) = -x-2
in finding x we need to implies that we already know f(x) = 12
therefore:
f(x) = -12 - 2
we need to know this laws that - × - is = +
this give us to the final answer:
12 + 2 = 14
Answer:
14
Step-by-step explanation:
y = 12
12 = x - 2
14 =x
Your mother bought several full packets of eggs. She opened all the packs and kept all the eggs in the fridge. You later counted all the eggs and found there are 46 eggs. One single packet looks as shown below. Do you think shopkeeper cheated your mother? Justify.
Answer:
Even when the answer is not complete, most likely yes, she was cheated.
Step-by-step explanation:
The question does not include how a packet looks, however since the total egg count is 46 units, this number is only divisible by 2 and 23.
So unless each egg packet contains 2 or 23 eggs, any other size would mean a packet had less eggs than expected.
Usually eggs come in packs of 6 or 12 units, so to sum 46 eggs or more you would need:
If 6 eggs per packet:
46/6 = 7,66 packets -> she must have bought 8 packets and should have 48 eggs, meaning there are 2 eggs missing.
If 12 eggs per packet:
46/12 = 3,83 packets -> she must have bought 4 packets and should have 48 eggs, meaning there are 2 eggs missing.
That's why it is safe to assume some packets had less eggs than expected.
Which line is perpendicular to y = 4x + 5?
A. y = -4x + 3
B. y = -1/4x + 6
C. y = x - 4
D. y = 1/4x - 3
The sum of the first and last of four consecutive integers is 33
If x is the first integer, then the fourth integer is x + 3. The sum of these is 33, so
x + (x + 3) = 33
2x + 3 = 33
2x = 30
x = 15

there are 300 students in 7th grade. Paul takes a random sample to find out which fall sport students in 7th grade prefer. which group of students represents the most valid sample?
Answer:
A random sample of at least 150 students.
Step-by-step explanation:
If you pick athlets they might pick sports they are biased towards, so the best would be random people so that you don't get a biased answer.
Answer: C = 10 students from each 7th grade homeroom
Step-by-step explanation:
The more students from each homeroom represents a larger population that creates less of a chance for having a bias sample.

Someone pls help and write the equation pls and the answer
Answer:[tex](-7-2)=-3(-3-0)[/tex]
Step-by-step explanation:
First use slope intercept form to find the value of b (the y intercept). The slope intercept formula is
[tex]y=mx+b[/tex]
Since we are given the point (-3,2), we can say that y=2 and x=-3. m=-3. Then we get
[tex]2=-3(-3)+b[/tex]
[tex]2=9+b[/tex]
[tex]b=-7[/tex]
Since we now have the y intercept, we can convert it to a point: (0,-7). Plug this into the point slope equation:
[tex](y_{1}-y_{2})=m(x_{1}-x_{2})[/tex]
Our first point is (-3,2). Our second point is (0,-7). Therefore:
[tex]x_{1}=-3\\y_{1}=2\\x_{2}=0\\y_{2}=-7\\m=-3[/tex]
Plugging into the equation, we get
[tex](-7-2)=-3(-3-0)[/tex]

Answer:
112
Step-by-step explanation:
Supplementary angles means that angle A and angle B added together equal 180˚. This mean we can re-write the angle measures into an algebra problem
A(3x+16) + B(2x + 4 ) = 180
Or
5x + 20 = 180
5x + 20 - 20 = 180 - 20
5x = 160
5x/5 = 160/5
x = 32
Now that we know that X = 32, we can plug 32 into the measure of angle A.
A(3x+16)
A(3(32)+16)
A(96+16)
A(112)
Angle A equals 112˚ and Angle B equals 68˚.
Factor x^2+x-12 = 0 and x^2-6x+9 = 0.
Answer: x^2+x-12 = 0 ⇒ x = -4 or x = 3 and x^2-6x+9 = 0 ⇒ x= 3
x^2+x-12 = 0 (Find two numbers that add to 1 and multiply to -12)
x^2-3x+4x-12 = 0 (Factor out like terms)
x(x-3)+4(x-3) = 0 (Group common terms)
(x-3)(x+4) = 0 (Set each term to equal 0 and solve for x)
∴ x = -4 or x = 3
x^2-6x+9 = 0 (It's a perfect square trinomial)
(x-3)^2 = 0
∴ x = 3
Answer: x = -4 and x = 3 for the first one. x- 3 for the second one.

2x+ 1 = 19
This is supposed to be two step equations.
Answer:
x=0.1
Step-by-step explanation:
2x+1+=19
19-1=18
2x=18
2/18=0.1
x=0.1
Answer:
x= 9
Step-by-step explanation:
First I would subtract the 1 from 19 which leaves me with 18 then divide both sides by 2 so 2x/2 = 18/2 which gives me 9 now to check. 2 multiplied by 9 =18 plus 1 =1 9. and thats how I get the answ.r

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mo walked 12 miles in 3 hours.
In 1 hour Mo walked= 12/3
= 4 miles
and, in 5 hours Mo walked
= 5 x 4
= 20 miles.
Hence, Mo walked 20 miles in 5 hours.

the easiest way to do this problem is take away the c's in the expression and add them to your answer at the end which you would just be multiplying 5 x3 which = 15 then you would put the c next to the 15 so the answer would be 15c
The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box? 11 ounces per box 12 ounces per box 15 ounces per box 16 ounces per box
Answer:
15 ounces per box
Step-by-step explanation:
What is the weight, in ounces, of one box?
165ounces/ 11 boxes
This means
165ounces per 11 boxes
Hence:
11 boxes = 165ounces
1 boxes = x ounces
Cross Multiply
11x = 165 × 1
x = 165/11
x = 15 ounces
Therefore, the weight, in ounces, of one box is 15 ounces per box.
Answer:
15 ounces per box
