Answers
Answer:
i think maybe 6*9x
Step-by-step explanation:
Step-by-step explanation:
So this is how it works
The bracket represents times. So, you have to times 6 to 3 and also 6x
Next, write down the values after times it. You will get 18+36x
NOTE: This is for expansion only
For factorisationBring the x to your right and bring the numbers to your left. Then calculate the value and that's your answer

The endpoints of MN are located at M (-4, 4) and N (2,-2). What are the coordinates of the point P that divides MN such that MP : PN is equal to 2: 1?
(-3.5, 2.5)
(-2,2)
(-1, 1)
(0,0)
Answers
Answer:
The coordinates of the point P is (0,0)
Step-by-step explanation:
Here, we want to find the coordinates of point P which divides the segment MN in the ratio 2 to 1.
Mathematically, what we shall use here is the internal division formula;
The internal division formula is given as follows;
(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
From the question;
x1 = -4
x2 = 2
y1 = 4
y2 = -2
m = 2
n = 1
By substituting, we have;
(1(-4) + 2)2))/(1 + 2) , (1(4) + 2(-2))/(1+2)
= (-4 + 4)/3 , (4-4)/3
= (0,0)

Step-by-step explanation:
a) Si se suman las probabilidades de venta, es decir:
Probabildad de vender 0 auto ( es decir que no vendió) = 0,19
Probabildad de vender 1 auto = 0,38
Probabildad de vender 2 autos = 0,29
Probabildad de vender 3 autos =0,15
Da por resultado: 1,01
1,01 > 1

The perimeter of a child's rectangular sandbox is 18 feet. Part A:if the length of the sandbox is one foot longer than the width, write an equation that can find the length and width of the sandbox. Part B:using your equation from part a, find the dimensions of the Childs sandbox. Show your work
Answers
Answer:
Length = 5 feet
Width = 4 feet
Step-by-step explanation:
Perimeter of the sandbox = 18 feet
Perimeter of a rectangle = 2(length + width)
the length of the sandbox is one foot longer than the width
Let
Width = x
length = x + 1
Perimeter of a rectangle = 2(length + width)
18 = 2{(x+1) + x}
18 = 2{x + 1 + x)
18 = 2(2x + 1)
18 = 4x + 2
4x = 18 - 2
4x = 16
Divide both sides by 4
x = 16/4
= 4
Width = x = 4 feet
length = x + 1
= 4 + 1
= 5 feet

Rafael can choose plan a or Plan B for his long-distance charges. For each plan, cost (in dollars) depends on minutes used (Per month) as shown below.
Answers
Answer:
a. Plan B; $4
b. 160 mins; Plan B
Step-by-step explanation:
a. Cost of Plan A for 80 minutes:
Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:
f(80) = 8
This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.
Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.
Plan B will cost $12.
Therefore, Plan B cost more.
Plan B cost $4 more than Plan A ($12 - $8 = $4)
b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.
At 160 minutes, they both cost $16
The plan that will cost less if the time spent exceeds 160 minutes is Plan B.

Fraction strips uses (least) common denominators, thus splitting big fraction into sum with like denominators and thus making addition possible.
Fraction strips require three major steps.

2. Find the common denominator which should be least of all.
3. Now calculate the sum on new converted fractions.

1-6. Indicate whether each table or graph represents a proportional

pls answer! nobody answer right and I am sick of failing this is for a mastery
Answers
Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
[tex]\frac{x}{y}=k[/tex] where 'k' is the proportionality constant.
From table (1),
[tex]\frac{1}{5}=\frac{2}{9}\neq \text{Constant}[/tex]
Therefore, relationship is not proportional.
From table (2),
[tex]\frac{1}{6}=\frac{3}{18}=\text{constant}[/tex]
True.
So the relationship will be proportional.
From table (3),
[tex]\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}[/tex]
Which is constant.
Therefore, relationship will be proportional.
From table (4),
[tex]\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103[/tex]
Which is constant for every term.
Therefore, relationship will be proportional.
