1.75, 1.5, 1.25, 1, 0.75, 0.5, 0.25, 0
(Idk if 0 would be considered to be positive but the rest are for sure.)
To find these just subtract 0.25 each time until you hit a negative number.
one angle of an isosceles triangle measure 140 degrees. which other angles could be in that isosceles triangle?
Answer:
20!
Step-by-step explanation:
Isosceles triangles have 2 angles are the same. Since we can't do 140, because interior angles of a triangle equal 180, then we need to subtract 140 from 180. 180-140=40. 40/2 because of 2 angles=20. 20 is the angle.
Answer:
20

What is the equation of the line that passes through (4, -1) and (-2, 3)?
Answer:
y= - 4/6x+1.66
Step-by-step explanation:
To get the slope you subtract y2-y1 / x2-x1. This gives the slope. Then you need to get the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Read the problem to choose the correct method, then solve. A farmer buys a tractor for $50,000. If the tractor depreciates 10% per year, use an exponential function to find the value of the tractor in 7 years. AD CO Exponential Growth, $97,435.86 Exponential Decay, $23,914.85 Exponential Growth, $315,000 Exponential Decay, 21,523.36
Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:
[tex]y=a\cdot (1-r\%)^{t}[/tex]
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
[tex]y=a\cdot (1-r\%)^{t}[/tex]
[tex]=50000\times (1-0.10)^{7}\\\\=50000\times 0.4782969\\\\=23914.845\\\\\approx 23914.85[/tex]
Thus, the correct option is, Exponential Decay, $23,914.85.

what is the slope of (19,14) & (21,19)
Step-by-step explanation:
Hey there!
Given; The points are; (19,14) and (21,19).
Note: Use slope formula.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{19 - 14}{21 - 19} [/tex]
Simplify it.
[tex]m = \frac{5}{2} [/tex]
Therefore, slope(m)= 5/2.
Hope it helps...
Answer:
slope = 5/2
Step-by-step explanation:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]\frac{19-(14)}{21-(19)}[/tex]
m=[tex]\frac{5}{2}[/tex]

General Formulas and Concepts:
A box at an angle signifies a 90° angle.
The 2 angles that add up to 90° are called Complementary AnglesStep-by-step explanation:
Step 1: Set up equation
The 2 angles are Complementary Angles. They must add up to 90°.
(6y + 5) + (8y + 1) = 90
Step 2: Solve for y
Combine like terms: 14y + 6 = 90Subtract 6 on both sides: 14y = 84Divide both sides by 14: y = 6Answer:
y = 6
Step-by-step explanation:
So, the two angles sum up to 90 degrees.
Based on that, form an equation;
6y + 5 + 8y + 1 = 90
simplify,
6y + 5 + 8y + 1 = 90
14y + 6 = 90
inverse operations,
14y + 6 = 90
-6 -6
14y = 84
/14 /14
y = 6

1.Factor: 4x^2+28x-36
2.Factor: 125x^6-27y^15
3.Multiply: (4x-7)(5x-8)
Answer:
1. 4(x² + 7x - 9)2. (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. 20x² - 67x + 56Step-by-step explanation:
1. factor 4x^2+28x-36
= 4x² + 28x - 36
re-write 36=4*9, and 28=4*7
= 4x² + 4 * 7x - 4 * 9
factor out common term:
= 4(x² + 7x - 9)2. factor 125x^6-27y^15
= 125x⁶ - 27y¹⁵
=(5x²)³ - (3y⁵)₃
apply difference of cubes: x³-y³ = (x-y)(x²+xy+y²)
= (5x² - 36y⁵)(5²x⁴ + 5 * 3x²y⁵ + 3²y¹⁰)
refine:
= (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. multiply (4x-7)(5x-8)
apply the FOIL method
= 4x * 5x + 4x (-8) + (-7) * 5x + (-7) (-8)
= 20x² - 67x + 56-2(4x - 2) < - 8x + 4
Answer:
Both sides are equal.
So less than symbol can't be use in this case.

Car Y travels 105 miles on 3 gallons of petrol. Car Z travels 80 miles on 9 litres of petrol.
Which car has better petrol consumption ( more miles per gallon)?
You may use the fact that 1 gallon =4.5 litres
Options are
A. None
B. Y
C. Z
Answer:
Car Z has better petrol consumption. Choice C. Z
Step-by-step explanation:
Petrol Consumption
Car Y travels 105 miles on 3 gallons of petrol. The average consumption is 105 / 3 = 35 miles/gallon
Car Z travels 80 miles on 9 litres of petrol. Since 1 gallon=4.5 litres, the consumption of car Z is 9/4.5= 2 gallons. The average consumption is 80/2 = 40 miles/gallon.
This means that car Z has better petrol consumption. Choice C. Z
Two times the difference of 13
and a number is -4. Write an
equation representing this
situation and solve for the
number.
Answer:
Step-by-step explanation:
let number be x
CASE 1) when x>13
2(x-13) = 4
2x - 26 = 4
2x = 30
x = 15
CASE 2) when x<13
2(13 - x) = 4
26 - 2x = 4
26 - 4 = 2x
22 = 2x
11 = x
