Answer:
ylyiky lio
Step-by-step explanation:
if (x) = x+8 and g(x) = -4x-3, find (f+ g)(x).
A. (F+ 9)(x) = 5x +11
B. (f+9)(x) = -3x+5
C. (f+ g)(x) = 3x - 5
D. (f+ 9)(x) = -5x - 11
Answer:
Answer=B
(f+g)(x)=-3x-5
Step-by-step explanation:
f(x)=x+8.
g(x)=-4x-3.
(f+g)(x) means f(x)+g(x),So
(x+8)+(-4x-3)
(add all same terms together)
=(x+(-4x))+(8+(-3))
=-3x+5
so,
(f+g)(x)=-3x+5

Answer:
∆PQR: Equilateral Triangle
∆PRT: Scalene Triangle
∆TQS: Isosceles Triangle
∆QNP: Right Triangle
Step-by-step explanation:
∆PQR is an Equilateral Triangle because all of its angles are equal (60°).
∆PRT is a Scalene Triangle because none of its sides are equal.
The triangle above it is equilateral, and one side length is 14, meaning all of its side lengths are 14.
This makes the top of ∆PRT 14. The hypotenuse is given and it’s 18.
The last side left is clearly shorter than both, meaning none of the sides are equal.
∆TQS is an Isosceles Triangle because 2 angles are equal.
The base angles are both 76°.
∆QNP is a Right Triangle because segment QN and PR are perpendicular, creating two 90° angles on both sides.
For number 10, I suggest using a graphing calculator or desmos to graph the points. (Or you can just add the points but I suggest graphing).
From there, you can count the length of each side.
Segment DE: 9
Segment EF: 8
Segment FD: 10
This makes ∆DEF in number 10 a Scalene Triangle because none of its sides are equal.
For number 11, I also suggest graphing the points and counting the sides.
Segment DE: 7
Segment EF: 9
Segment FD: 7
This makes ∆DEF in number 11 an Isosceles Triangle because 2 of its sides are equal.
Hope this helps! :)
A reflection across the x-axis maps the point (4,-5) to the point
Answer:
(4,5)
Step-by-step explanation:
A reflection is a mirror image of the shape.
A reflection across the x-axis maps point (4,-5) to point (4. 5).
What is reflection?A reflection is a mirror image of the shape.
After the reflection, every point in a figure is equidistant from each corresponding point in the reflected figure.
We have,
A point = (4, -5)
The point is reflected across the x-axis.
The reflection formula is given as:
Reflection across the x-axis:
(x, y) → (x, -y)
Reflection across the y-axis:
(x, y) → (-x, y)
The point (4, -5) reflected across the x-axis is:
(4, -5) → (4, - (-5)) = (4, 5)
Thus,
A reflection across the x-axis maps point (4,-5) to point (4. 5).

A bind is flying north with a mass of 2.5 kg has a momentum of 17.5 kg m/s. At what velocity
is it flying?
(P=m*v) P=momentum, m=mass, and v=Velocity,
Answer:
6 m/s
Step-by-step explanation:
Plug in the mass and momentum into the equation, and solve for v:
p = mv
17.5 = 2.5(v)
7 = v
So, the velocity is 6 m/s

Workout the value of 3x-4y when x=3and y=2
Answer:
gimme your disc ill help
Step-by-step explanation:
Solve.
x^2 + 4 = 0.
Answer:
No real solutions
Step-by-step explanation:
You use the quadratic formula.
x = −b ± √(b^2 − 4ac)/2a where y = ax^2 + bx + c
b is 0, a is 1, and c is 4.
-0 ± √(0^2 − 4 x 1 x 4)/ 2(1)
±√(-16)/2
Split √(-16) into √(16) and √(-1).
Now, i = √-1
So you get ±√(-16) = ±4i.
The original equation was ±√(-16)/2.
±4i / 2 = ±2i
The answer is x = ±2i
(Note: ± means positive or negative)

If an investment account starts with $3900, and grows with 2.1% interest, compounded continuously. How much is the account worth after 10 years? Round your answer to the nearest dollar. Do NOT round until you have calculated the final answer.
Answer:
If they are asking amount it is $4800.893013; $4800 (nearest dollar)
If they are asking the amount for interest is $900.8930129; $900 (nearest dollar)
Step-by-step explanation:
Compound interest Formula:
Amount = principle( 1+ rate/100)^n
Information from the question.
-So how you put it is the principle is $3900; the rate is 2.1%; the n is 10.
How to apply it?
- Just substitute in the values;
Amount=3900(1+2.1/100)^10
=4800.893013
~4800 ( nearest dollar)
》That is for amount.
Interest=4800.893013-3900
=900.893013
~900 ( nearest dollar)
》That is for interest.

El lado de un rectángulo mide el tiple de su ancho, si el perímetro mide 96 cm ¿cuáles son sus dimensiones?
Answer:
Ancho 12 cm, Largo 36 cm
Step-by-step explanation:
lamamos al ancho X y por tanto el largo será 3X
Como el perímetro es la suma de los 4 lados, tenemos la siguiente igualdad:
3X+3X+X+X=96 cm
8X=96 cm
X=96 cm/8
X=12 cm
El ancho mide 12 cm
Si el largo es el triple, entonces 3 x 12 = 36 cm

D. The median is less than the mean, and the distribution has two outliers.
Full question attached
Answer
Option A: the median is greater than the mean and the distribution has only one outlier
Explanation:
From the data median is definitely greater than mean as we can see from the data of siblings, median which is middle number is somewhere greater than the mean 3.5 from the question. Also from the definition of an oulier and given that the median is just one middle number in data, there is just one outlier in the data
