What is the coefficient: 4 - 2y
The coefficient of the variable y for the given equation 4 - 2y is -2.
What is the coefficient?A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.
We have,
An equation 4 - 2y,
So,
In the above-given expression,
We have only one variable and one Constant term,
i.e.
Constant term = 4
And,
Variable term = -2y
So,
In the variable term,
The coefficient of y = -2
So,
The coefficient of y is -2.
Hence, we can say that the coefficient of the variable y in the given equation is -2.

The length of a rectangle is 3 centimeters less than five times its width. Its area is 14 square centimeters. Find the dimensions of the rectangle.
Find the Width and the Length
W=
L=
Answer:
The length of rectangle is 7 cm and width is 2 cm.
Step-by-step explanation:
Given that:
Area of rectangle = 14 square centimeters
The length of a rectangle is 3 centimeters less than five times its width.
Let,
L be the length and W be the width of the rectangle.
L = 5W - 3
Area of rectangle = Length * Width
14 = (5W-3)*W
[tex]14=5W^2-3W\\5W^2-3W-14=0[/tex]
Factorizing the equation;
[tex]5W^2-10W+7W-14=0\\5W(W-2)+7(W-2)=0\\(5W+7)(W-2)=0[/tex]
Either,
5W+7 = 0
5W = -7
W = -7/5
Or,
W-2 = 0
W=2
As width of rectangle cannot be negative, therefore,
Width = 2 centimeters
Length = 5(2) -3 = 10-3 = 7
Hence,
The length of rectangle is 7 cm and width is 2 cm.
Suppose that in a large metropolitan area, 84% of all households have cable tv. Suppose you are interested in selecting a group of six households from this area. Let X be the number of households in a group of six households from this area that have cable tv. For what proportion of groups will at most three of the households have cable tv?
Answer:
0.05606
Step-by-step explanation:
This is a binomial probability distribution problem.
84% of all households have cable TV, thus;
p = 0.84
There are six households from this area, thus; n = 6
Formula for this binomial distribution is;
P(X) = C(n, x) × p^(x) × (1 - p)^(n - x)
We want to find the proportion of groups where at most three of the households have cable TV.
Thus, it's is;
P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
P(X = 0) = C(6, 0) × 0.84^(0) × (1 - 0.84)^(6 - 0) = 0.00001678
P(X = 1) = C(6, 1) × 0.84^(1) × (1 - 0.84)^(6 - 1) = 0.000528
P(X = 2) = C(6, 2) × 0.84^(2) × (1 - 0.84)^(6 - 2) = 0.006963
P(X = 3) = C(6, 3) × 0.84^(3) × (1 - 0.84)^(6 - 3) = 0.04855
Thus;
P(X ≤ 3) = 0.00001678 + 0.000528 + 0.006963 + 0.04855 = 0.05606

Answer:
36miles
Step-by-step explanation:
Given parameters:
Rate = 12mph
Time = 3hr
Unknown:
Distance = ?
Solution:
The given rate amount is the speed. Speed is the distance divided by the time.
It is mathematically expressed as:
Speed = [tex]\frac{distance}{time}[/tex]
Distance = Speed x time
Distance = 12 x 3 = 36miles

Mrs. Miller has only $42.50 to spend at walmart. She buys a shirt that costs $29, including tax. She wants to buy some bracelets for 4.50 each, including tax. Write an equation to determine x, the maximum number of bracelets Mrs. Miller can buy
Answer: 2
Step-by-step explanation: 42.50 is the max she can spend there’s .08 cent per dollar. $29 dollars for the shirt plus tax it’ll be 31.32 now Mrs.Miller is left with 11.18 out of her 42.50. Divide 11.18 by 4.50 because that’s the cost of each bracelet. 4.50 multiplied by 2 equals 9 plus tax it’ll be 9.72. 11.18 she had left minuse the 9.72 she’s left with 1.46

A line intersects the points
(-4, 5) and (-6, 3).
Write an equation in point-slope form
using the point (-4, 5).
y- [?]=l(«-)
Answer:
y -y1 = m(x-x1) (this is point slope form)
find the slope using the equation (y2-y1)/(x2-x1) (plug in the points)
(-4,5) is point 1 and (-6,3) is point 2
(3-5)/(-6-(-4))
-2/ -2
1 (this is the slope)
and then plug in all the things you know
y - 5 = 1 ( x - ( -4))
