what is the slope of the line that passes through (4,-9) and
(1,3)?
Answer:
slope = - 4
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 9 ) and (x₂, y₂ ) = 1, 3 )
m = [tex]\frac{3-(-9)}{1-4}[/tex] = [tex]\frac{3+9}{-3}[/tex] = [tex]\frac{12}{-3}[/tex] = - 4
Answer:
[tex]m=-4[/tex]; the slope is -4
Step-by-step explanation:
[tex]slope=\frac{rise}{run} =\frac{y^2-y^1}{x^2-x^1}[/tex]
coordinates: (4,-9) (1,3)
[tex]\frac{3-(-9)}{1-4}=\frac{-12}{-3} =-4[/tex]
= -4 is your answer

Which figures can be circumscribed by a circle? Select all that apply.
Answer:
A, B, C, D
Step-by-step explanation:
They All add up to 360
Answer:
B and D
Step-by-step explanation:
figures which can be circumscribed by a circle are called cyclic quadrilaterals.
the opposite angles of a cyclic quadrilateral sum to 180°
A
∠ B + ∠ D = 82° + 56° = 138° ≠ 180° ← not cyclic
B
∠ B + ∠ D = 103° + 77° = 180° and ∠ A + ∠ C = 90° + 90° = 180° ← cyclic
C
∠ B + ∠ D = 112° + 90° = 202° ≠ 180° ← not cyclic
D
∠ B + ∠ D = 90° + 90° = 180° and ∠ A + ∠ C = 90° + 90° = 180°← cyclic
Then B and D can be circumscribed by a circle

How many solutions does this linear system have?
O one solution: (0, 0)
O one solution: (1,-4)
Ono solution
O infinite number of solutions
Answer:
infinite number of solutions
Step-by-step explanation:
Given equations:
y = -6x+2-12x - 2y = -4Rearrange the second equation to make y the subject:
⇒ -12x - 2y = -4
⇒ -12x - 2y + 2y = -4 + 2y
⇒ -12x = -4 + 2y
⇒ -12x + 4 = -4 + 2y + 4
⇒ -12x + 4 = 2y
⇒ (-12x + 4) ÷ 2 = 2y ÷ 2
⇒ y = -6x + 2
Comparing the rearranged equation with the first equation, we can see that both equations are the same.
Therefore, as there is only one line, there are an infinite number of solutions.

Mike paid $\$1.25$ for a stamp three years ago. He was just offered double that amount for the stamp. Assuming the stamp's offer price doubles every three years, how many dollars will he be offered in 12 more years
Answer: $40
Step-by-step explanation:
If the worth of the stamp is double that of its original price 3 years ago ($1.25), the current price of the stamp should be $2.50. If that doubles every 3 years the answer should look something like this:
3 years: $5 (2.50X2=5)
6 years: $10 (5X2=10)
9 years: $20 (10X2=20)
12 years $40 (20X2=40)
In 12 years the stamp will be worth $40.

answer:
25/68
Step-by-step explanation:
total number-750
males-440
females-750-440=310
those with Cell -345
females with cell -205
males-345-205=140
male with cell -140/345
=25/68
Answer:
25/68
Step-by-step explanation:
total number=750
Male=440
Female=750-440
=310
People with cell phone= 345

the lengths of the side of a triangle are 8,10,12 is the triangle acute, right, or obtuse?
Answer:
acute triangle
Step-by-step explanation:
because (12)^2 = 144 while [tex]8^{2}[/tex] + [tex]10^{2}[/tex] = 164 which means the sum of it's smaller angles are greater than it's greatest angle so it's an acute triangle
Answer:
take the two smaller sides, call them a and b. call the longest side c.
if a^2 + b2 = c^2 you have a right triangle
if < c^2 it's acute
if > c^2 it's obtuse
in addition, if you can find a,b,c such that
a=b=c it's equilateral
a=b≠c it's isosceles
a≠b≠c it's scalene
plug in your numbers and make your choice.

Which equation could be solved using this application of the quadratic formula? a. -2x2 − 8 = 10x − 3 b. 3x2 − 8x − 10 = 4 c. 3x2 8x − 10 = -8 d. -2x2 8x − 3 = 4
The equation that can be solved when the given quadratic formula is used is c. 3x² + 8x − 10 = -8.
How can we use quadratic equations?The given quadratic equation is:
x = (-8 ± √(8² - 4(3)(-2))) / 2 (3)
Rewriting the quadratic equation in option C gives:
3x² + 8x − 2 = 0
Seeing as a quadratic equation takes the form:
x = (-b ± √(b² - 4(a)(c))) / 2 (a)
The formula becomes:
x = (-8 ± √(8² - 4(3)(-2))) / 2 (3) which is the given quadratic formula.
In conclusion, option C is correct.

prove that √5 + 7 is irational
Explanation:
What are irrational numbers?
Irrational numbers include numbers like: π, 12π, ∛2, √11, √12, 4√2
Note: √4 = ± 2, √16 = ± 4 and others which completely square root are still rational numbers as they can be written as whole number integers.
Here given number: √5 + 7
It is an irrational number as it cannot be simplified further to a whole number. In decimals: 9.236067977... and keeps repeating. It is an example of non-recurring decimals. Hence, it is an irrational number.
