What is the slope of a line perpendicular to a line that's passes through (3,8) and (1,-4)?
A. -1/6
B. -1/2
C. 2
D. 6
Answer:
-1/6
Step-by-step explanation:
First find the slope of the line through the points
m = (y2-y1)/(x2-x1)
= (-4-8)/(1-3)
= -12/-2
=6
Now we need to find the slope of the line that is perpendicular
Perpendicular lines multiply to -1
6 * mp = -1
mp = -1/6

Answer:
x≤-3 2 ≤x<7
Step-by-step explanation:
(x^2+x-6) /(x-7) ≤0
Factor the numerator
(x+3)(x-2) / (x-7)≤0
Critical points are
X =-3 X =2 X=7
We need to check the values when
x≤3 -3 ≤ x≤2 2 ≤x<7 x>7
(x cannot be 7 because then the denominator is zero)
and see when it is less than 0
Substitute a value in and see if factor is positive or negative
x≤-3
(negative)(negative) / (negative) = negative
-3 ≤x≤2
(positive)(negative) / (negative) = positive this range does not work
2 ≤x<7
(positive)(positive) / (negative) = negative

Find the other endpoint of the line segment with the given endpoint and midpoint.
Find the distance between the two x values: -10 to -7 is 3 units, so add to the midpoint: -7 + 3 = -4
The x value is -4
Now do the same for y:
7 to -3 is 10 units
Because the midpoint is less than the end point subtract:
Y = -3 -10 = -13
Y = -13
The endpoint would be (-4, -13)

Points P and Q belong to AB. If AB = a and AP = 2PQ = 2QB, find the distance between: the midpoints of AP and QB.
NO explanation needed. I need this fast
Answer:
The distance between midpoint of AP and QB is [tex]\frac{5a}{8}[/tex].
Step-by-step explanation:
Given that: AB = a
AP = 2PQ = 2QB
Thus,
PQ = QB = [tex]\frac{a}{4}[/tex]
PQ + QB = [tex]\frac{a}{4}[/tex]+ [tex]\frac{a}{4}[/tex]
= [tex]\frac{a}{2}[/tex]
AP = [tex]\frac{1}{2}[/tex] a = [tex]\frac{a}{2}[/tex]
The distance between midpoint of AP and QB can be determined as;
[tex]\frac{AP}{2}[/tex] + PQ + [tex]\frac{QB}{2}[/tex]
= [tex]\frac{a}{4}[/tex] + [tex]\frac{a}{4}[/tex] + [tex]\frac{a}{8}[/tex]
= [tex]\frac{2a+2a+a}{8}[/tex]
= [tex]\frac{5a}{8}[/tex]
Therefore, the distance between midpoint of AP and QB is [tex]\frac{5a}{8}[/tex].

The table shows to linear functions in the function values for different values of X. Which expression represents H(x)?
Answer:
(g + f)(x)
Step-by-step explanation:
the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).
The expression of function H (x) is (g + f) (x).
Option 2 is true.
Here,
The function f (x) = -x - 4 and g(x) = x + 3
The value of H (x) is in the table is -1.
We have to find the expression to represents H(x).
What is Linear function?
A linear function is a simple function usually composed of constants and simple variables without exponents.
Now,
The function f (x) = -x - 4 and g(x) = x + 3
⇒( f + g ) (x) = f (x) + g(x)
= -x - 4 + x + 3
= -1
Which is same as the value of H (x) is in the table.
Hence, The expression of function H (x) is (g + f) (x).
Option 2 is true.

A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?
____gallons
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
Answer:
4 gallons
Step-by-step explanation:
The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the values of x be set A = { 2 , 3 , 4 }
Let the values of y be set B = { 4 1/2 , 6 3/4 , 9 }
So , the unit rate of change can be calculated by slope and linear equation of line
So , Slope m is
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( 6 3/4 - 4 1/2 ) / ( 3 - 2 )
m = 2.25
So , the equation will be y = mx
y = 2.25x
Therefore , the unit rate of change is y = 2.25x
Hence ,

Seth has just decided to replace his computer. His old computer cost him $1,433 when he bought it exactly seven years ago. Seth paid for it with his credit card, which has an APR of 11.70%, compounded monthly. He made no other purchases with the card and paid off his balance after two and a half years of making identical monthly payments. The computer consumed about $0.79 of electricity every day. In total, what percentage of the lifetime cost of the computer did the electricity make up? (Assume that two out of the seven years were leap years, and round all dollar values to the nearest cent.)
a.
82.157%
b.
58.500%
c.
21.718%
d.
54.898%
Please select the best answer from the choices provided.
A
B
C
D
Answer:
The answer is D
Step-by-step explanation:
The solution would be like this for this specific problem:
Cost of the computer:
i = 0.117 / 12
i = 0.00975
= monthly payment
= (i * P * (1 + i)^n) / ((1 + i)^n - 1)
= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1)
= $55.32
Electricity cost:
= $0.79 * 365.25 * 7
= $2019.83
Electricity Percentage:
= $2019.83 / ($2019.83 + $1659.60)
= 54.89%
Electricity:
= ($0.79 * 365 * 5) + ($0.79 * 366 * 2)
= $2020.03
Electricity Percentage:
= $2020.03 / ($2020.03 + $1659.60)
= 54.898%
In total, the electricity made up 54.898% of the lifetime cost of the computer.

600 feet of fence surround a rectangular playground that is 100 feet wide. How long is the playground? A.400 b.500 c.300 d.200
Answer:
A.400
Step-by-step explanation:
Well perimeter for a rectangle is l+l+w+w
100+100+l+l=600
200+2l=600
Subtract 200 from both sides
2l=400
Divide both sides by 2
l = 400 feet
The length of the rectangle is 400 feet long.
