Answer:
Slope/m=1/2, y-intercept=-4
Step-by-step explanation:
Y=mx+b is slope-intercept form. So in the equation y=1/2x-4, m stands for the slope, and in the equation 1/2 is in the place of m. B stands for the y-intercept, and in its place is -4.

The perimeter of a rectangular lot of land is 448 A. This includes an easement of x feet of uniform width Inside the lot on which no building can be done . If the buildable area is 140 ft by 64 determine the width of the easement.
Answers
Answer:
[tex]5\ \text{ft}[/tex]
Step-by-step explanation:
Perimeter of rectangular lot = [tex]448\ \text{ft}[/tex]
The width of the easement is [tex]x\ \text{ft}[/tex]
Buildable area 140 ft by 64 ft
[tex]2(140+2x)+2(64+2x)=448\\\Rightarrow 140+2x+64+2x=\dfrac{448}{2}\\\Rightarrow 204+4x=224\\\Rightarrow x=\dfrac{224-204}{4}\\\Rightarrow x=5\ \text{ft}[/tex]
The width of the easement is [tex]5\ \text{ft}[/tex].

What is the value of x in the equation 25x2 = 16. A. 5/4. B. 4. C. 4/5. D. 16/25
Answers
Answer:
x = ⅘
Step-by-step explanation:
For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.
25x² = 16
divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5

The difference of two numbers is 3, and the sum of three times the larger one and twice the smaller one is 19. Find the two numbers.
Answers
Answer:
small number = 28/5 or 5 3/5
larger number = 13/5 or 2 3/5
Step-by-step explanation:
x = small number
y = large number
set up a system of equations:
x - y = 3
3y + 2x = 19
using substitution method:
let x = 3 + y
3y + 2(3 + y) = 19
3y + 6 + 2y = 19
5y + 6 = 19
5y = 13
y = 13/5
solve for x:
x - 13/5 = 3
x = 15/5 + 13/5
x = 28/5
Use slope to determine if lines PQ and RS are parallel, perpendicular, or neither P(-3,14) q(2,-1) r(4,8) s(-2,-10)
Answers
Answer:
Neither
Step-by-step explanation:
The slope of PQ is -3.
The slope of RS is 3.
Parallel lines have the same slope. The slopes for perpendicular lines are the opposite of the reciprocal. PQ and RS are intersecting lines, but not parallel or perpendicular.
Find the equation of the line passing through (1,4) and (-2,-1).
Answers
Answer:
y=5/3x+7/3
Step-by-step explanation:
Here are the points: (1,4) and (-2, -1)
let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)
label the points:
x1=1
y1=4
x2=-2
y2=-1
now subsitute into the equation
m=(-1-4)/(-2-1)
m=-5/-3
m=5/3
the slope of the line 5/3
Here's the equation so far:
y=5/3x+b (b is a place holder)
we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>
let's use (1,4) as an example
4=5/3(1)+b
4=5/3+b
subtract 5/3 from both sides
7/3=b
Now, put it all together:
y=5/3x+7/3
Hope this helps!
Mike and Andy are each reading the same book mike reads 2\4 of the book on Tuesday and 1\3 of the book on Wednesday Andy reads 1\2 of the book on Tuesday and 1\5 of the book on Wednesday Andy says that all together he reads more of the book on Tuesday and Wensday then mike
Answers
Answer:
Andy's claim is incorrect
Step-by-step explanation:
Given
Mike:
[tex]Tuesday = \frac{2}{4}[/tex]
[tex]Wednesday = \frac{1}{3}[/tex]
Andy:
[tex]Tuesday = \frac{1}{2}[/tex]
[tex]Wednesday = \frac{1}{5}[/tex]
Required
Is Andy correct?
First, we need to calculate the fraction of book read by Mike.
[tex]Mike = \frac{2}{4} + \frac{1}{3}[/tex]
Take LCM
[tex]Mike = \frac{6+4}{12}[/tex]
[tex]Mike = \frac{10}{12}[/tex]
Convert to decimal
[tex]Mike = 0.833\\[/tex]
Next, we perform the same calcuation for Andy
[tex]Andy = \frac{1}{2} + \frac{1}{5}[/tex]
Take LCM
[tex]Andy = \frac{5+2}{10}[/tex]
[tex]Andy = \frac{7}{10}[/tex]
Convert to decimal
[tex]Andy = 0.70[/tex]
Andy's claim that he read more of the book is incorrect because 0.833 (for Mike) is greater than 0.70 (for Andy)
Marla bought 1250 pounds of pecans at $1.29 per pound and another 1500 pounds of pecans at $1.59 per pound. She sold all the pecans for \$6.75 per kilogram. After paying her suppliers, how much money did she make?
Answers
Answer:
After paying her suppliers, she made $4,575.
Step-by-step explanation:
First, you have to multiply the number of pounds purchased for the price:
$1.29*1250=$1,612.5
$1.50*1500=$2,250
Now, you can add both amounts to find the total cost:
$1,612.5+$2,250=$3,862.5
Now, you have to find the total amount of lb purchased and determine the kg they represent given that 1 kg is equal to 2.20 lb:
1250+1500=2750
2.20 lb → 1 kg
2750 lb → x
x=(2750*1)/2.20= 1250 kg
Now, you can find the total amount sold by multiplying the price per kilogram for the amount of kg:
$6.75*1250=$8,437.5
Finally, you have to subtract the total cost from the total amount sold:
$8,437.5-$3,862.5=$4,575
According to this, the answer is that after paying her suppliers, she made $4,575.
Sally has a budget for school stationery of $37, but has already spent $22.72 on books and folders. Let p represent the amount that Sally can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for p.
Answers
Answer:
[tex]p\le 14.28[/tex]
Step-by-step explanation:
Total budget for school stationery = $37
She has already spent $22.72 on books and folders.
Left amount = $37 - $22.72
= $14.28
Let p represent the amount that Sally can spend on other stationery. It implies that "p" must be less than or equal to $14.28 .
Hence, the required inequality is :
[tex]p\le 14.28[/tex]
