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))

What is the value of x?
Answer:
x = 16
Step-by-step explanation:
(x+2) + (7x+2) + (3x) = 180
Add like terms
7x + x + 3x = 11x
2 + 2 = 4
11x + 4 = 180
Subtract 4
11x + 4 = 180
11x = 176
Divide by 11
11x = 176
x = 16
Zelda rode her bike at a steady rate of 12 miles per hour for 3
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

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.

Is this problem a combination or permutation?
Suppose a group of 10 must pick an assistant, a representative, a treasurer, and a recorder. How many ways can this be done?
Answer: Permutation Problem
There are 5040 permutations possible
==================================================
Explanation:
Order matters because the positions are different.
(A,B,C,D) is different from (B,A,C,D) because the first means person A is the assistant while the second means person B is the assistant.
We have 10 choices for the first slot, 9 for the second, 8 for the third, and 7 for the fourth. We count down the values because a person cannot be reselected to serve multiple positions simultaneously.
Multiply out those values to get 10*9*8*7 = 5040
There are 5040 permutations possible.
---------------
As an alternative, you can use the nPr permutation formula with n = 10 and r = 4 like so
[tex]_n P_r = \frac{n!}{(n-r)!}\\\\_{10} P_{4} = \frac{10!}{(10-4)!}\\\\_{10} P_{4} = \frac{10!}{6!}\\\\_{10} P_{4} = \frac{10*9*8*7*6!}{6!}\\\\_{10} P_{4} = 10*9*8*7 \ \ \text{ ... note how this shows up again}\\\\_{10} P_{4} = 5040\\\\[/tex]
We get the same answer as before.
Answer:
Combination
Step-by-step explanation:
This is the answer because:
1) The difference between combinations and permutations is the ordering of each term.
Combinations - the order doesn't matter
Permutations - the order matters.
An example of this is, if you enter the number combination 5324 into your locker/cabinet, it won't open up because it is a different ordering and needs a specific combination which means it's permutation.
2) In this situation, the order doesn't not matter since they just want different ways to select an assistant, a representative, a treasurer, and a recorder.
Hope this helps! :D
A recipe calls for 3 cups of water for every 4 cups of flour.
What is the unit rate of water to flour, written as a decimal?
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
