What is the slope ( in simplest form) of the line through the points (-4,2) and (-16,-6)?
Answer:
2/3
Step-by-step explanation:
Slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
(-4,2) = (x1,y1)
(-16,-6) = (x2,y2)
Slope = [tex]\frac{-6-2}{-16+4}[/tex]
= [tex]\frac{-8}{-12}[/tex]
= [tex]\frac{2}{3}[/tex]

f(x) = 2x2 + 12x + 16
Answer:
[tex]x=-2;x=-4[/tex]
Step-by-step explanation:
The solution of the quadratic equation f(x) = 2x² + 12x + 16 will be negative 2 and negative 4.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The function is given below.
f(x) = 2x² + 12x + 16
The root of the equation will be given as,
f(x) = 0
2x² + 12x + 16 = 0
x² + 6x + 8 = 0
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) = 0
(x + 4)(x + 2) = 0
x = -2, -4
The solution of the quadratic equation f(x) = 2x² + 12x + 16 will be negative 2 and negative 4.

Find the m Angle J if m Angle K = 29° and they are complementary angles.
Answer:
∠J = 61º
Complimentary angles are angles that add up to 90º
∠J = 90º - ∠Kº
= 90º - 29º
=61º

How much of a radioactive kind of niobium will be left after 105 days if you start with 3,920 grams and the half-life is 35 days?
Answer:
"490 grams" would be the correct solution.
Step-by-step explanation:
The given values are:
Half time,
T = 35 days
Total time,
t = 105 days
As we know,
⇒ [tex]A=A_o(\frac{1}{2} )^{\frac{t}{T} }[/tex]
On substituting the values, we get
⇒ [tex]=3920\times (\frac{1}{2})^{\frac{105}{35} }[/tex]
⇒ [tex]=3920\times (0.5)^3[/tex]
⇒ [tex]=3920\times 0.125[/tex]

Answer:
Step-by-step explanation:
A square has a diagonal with the length of 8V7 inches. What is the length of the
sides?
Answer:
approximately 13.9 inches
Step-by-step explanation:
That's 8√6, not 8V7.
The four sides are of the same length (x). According to the Pythagorean Theorem, x² + x² = (diagonal length)² = (8√6)², or
2x² = 64(6) = 384
Dividing both sides by 2, we get:
x² = 192, or x² = 4(48). Then the side length is x = √16√12, or
x = 4√4√3 = 8√3. This is approximately 13.9 inches.

Step-by-step explanation:
Find the point-slope equation for
the line that passes through the
points (1, -9) and (-10, 101). Use
the first point in your equation.
Answer:
y - (-9) = -10 (x - 1)
Step-by-step explanation:
y = mx + b
m (slope) = (y'-y) / (x'-x) = (101 - (-9)) / (-10) - 1) = 110/(-11) = -10
pass (1 , -9)
m = (y - (-9)) / (x - 1) = -10
y - (-9) = -10 (x - 1)

i need help finding DE. I do not know what do to. Please help any tips will be appreciated:))
Given:
In triangle ABC, [tex]AB=11x-25,DE=4x+1[/tex].
To find:
The measure of DE.
Solution:
From the given figure, it is clear that D is the midpoint of AC and E is the midpoint of BC. So, the line segment DE is the mid-segment of the triangle ABC.
According to the triangle mid-segment theorem, mid-segment of a triangle is equal to half of its base.
Using triangle mid-segment theorem, we get
[tex]DE=\dfrac{1}{2}AB[/tex]
[tex](4x+1)=\dfrac{1}{2}(11x-25)[/tex]
[tex]2(4x+1)=11x-25[/tex]
[tex]8x+2=11x-25[/tex]
Isolate the variable terms.
[tex]8x-11x=-2-25[/tex]
[tex]-3x=-27[/tex]
[tex]x=\dfrac{-27}{-3}[/tex]
[tex]x=9[/tex]
The value of x is 9. So,
[tex]DE=4x+1[/tex]
[tex]DE=4(9)+1[/tex]
[tex]DE=36+1[/tex]
[tex]DE=36+1[/tex]
[tex]DE=37[/tex]
Therefore, the length of DE is 37 units.

Which of the following is the correct input-output table for the function? Y=6x+5
Answer:
The answer is table b.
Step-by-step explanation:
To solve this question, you can mentally calculate each value of each table, until you come to a wrong one. When you do, move on. To give an example:
Table a:
x input value: 1
y output value: 12
y true output value: 11
I did this by substituting the value of x in the equation given, so:
y = 6(1) + 5 = 11
Simply do this in your mind for each value, and you'll get your answer if every value in the table is correct!
find the total surface area of the shape
Answer:
510 ft²
Step-by-step explanation:
in the triangle
base (b) = 5 ft
height of the triangle (h1) = 12 ft
height of the prism = 15 ft
Now
Lateral surface area (LSA)
= perimeter of triangular base * height
= ( 13 + 5 + 12) * 15
= 450 ft²
Total surface area
= LSA + 2 * area of triangular base
= 450 + 2 * 1 / 2 * b * h1
= 450 + 5 * 12
= 450 + 60
= 510 ft²
Hope it will help :)❤

3(7x) – 2(4 - x)
Answer:
23x - 8
Step-by-step explanation:
The simplified form of the expression 3(7x) – 2(4 - x) is: 23x-8.
Here, we have,
given that,
the expression is:
3(7x) – 2(4 - x)
now we have to simplify this expression.
so, we have,
3(7x) – 2(4 - x)
= 21x - 8 + 2x
adding the like terms we get,
=> 23x - 8
Hence, The simplified form of the expression 3(7x) – 2(4 - x) is: 23x-8.

Jack paid $4:00 for 6 pounds of apples. What is the ratio of the price of apples to the pounds of apples?
Answer:
you get 1.5 pounds of apples per dollar (1 pound and 8 ounces)
Step-by-step explanation:
6 and 4 will not work so we need to use decimals
since we have a gap of two, we need to be able to use it four times
2=0.5
1.5 x 4 = 6
or we could just divide it... never mind forget it
your answer is 1.5 pounds of apples per dollar
