Answer:
39
Step-by-step explanation:
so the input is x and the out put is y
using this we know that x=10
let plug that into the function
y=4(10)-1
y=40-1
y=39
since y is the output, the output is 39.

x<-1 and x > 1. What does x equal.
Answer:
does not exist
Step-by-step explanation:
because no number is greater than 1 who is smaller than -1
Step-by-step explanation:
For x<-1, it is saying that all values for x are less than -1
and for x>1 it is saying that all values are greater than 1
So, Answer: there are no values for x that satisfy the equation

what is the state of degrees of 5m^5?
Answer:
degree=5 is your answer of your question
AB
Round your answer to the nearest hundredth.
С
4
A
25°
?
B
Answer:
AB ≈ 4.41
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos25° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{4}{AB}[/tex] ( multiply both sides by AB )
AB × cos25° = 4 ( divide both sides by cos25° )
AB = [tex]\frac{4}{cos25}[/tex] ≈ 4.41 ( to the nearest hundredth )

Which of these are characteristics of reptiles? Check all that apply. They undergo internal fertilization. Their urine is concentrated. They use their skin for gas exchange. They have two-chambered hearts. They are covered in scales.
Answer:
Answers Below. Have a wonderful day!
Step-by-step explanation:
They undergo internal fertilization: True Most reptiles undergo internal fertilization sexually when the sperm of a male reptile enters the cloaca of female reptiles, fertilizing the egg.
Their urine is concentrated: False Reptiles do not have the ability to produce liquid urine that is more concentrated than their own body fluid because they lack a structure in their nephron called the Loop of Henle.
They use their skin for gas exchange: False They cannot use their skin as an organ of gas exchange. Reptiles depend entirely on their lungs for this.
They have two-chambered hearts: False They have three-chambered hearts.
They are covered in scales: True All reptiles are covered in scales (snakes, lizards, turtles, etc.)

What is the measure of the missing angle?
Answer:
79 degrees
Step-by-step explanation:
You add the two angles and get 79. Then you subtract it from 180 because it is a straight angle. 180-101=79
Answer:
79
Step-by-step explanation:
28+73+x=180
a straight line is 180. That's how I got what it is equal to.
28+73= 101
101+x=180
subtract
180-101= 79
hope this helps!!
Can someone find the surface area
Answer:
front triangle: (6x4)/2 = 12
back triangle: (6x4)/2 = 12
side: 12x5 = 60
other side: 12x5 = 60
bottom: 12x6 = 72
12 + 12 + 60 + 60 + 72 = 216
216 cm squared

Lines m and n are parallel, solve for the following values of x. Tell which theorem you used(name the angle pair)
Answer:
x = 90 (Alternate exterior angles)
Step-by-step explanation:
Given that,
Lines m and n are parallel.
We need to find the value of x.
Here, (180-x) will be equal to x as the alternate exterior angles are equal. So,
(180-x) = x
180 = 2x
x = 90
So, the value of x is equal to 90°.

You have learned three ways for solving systems of equations: graphing, substitution and elimination.
Which method do you like best and why?
Answer:
Elimination
Step-by-step explanation:
Graphing takes too long, substitution can sometimes complicate things quickly, therefore I would use elimination as my prime method of solving systems of equations.

The area of Mark's laptop computer
screen is 12x2 + 3x in?. If the length is
3x, write an expression that represents
the width?
Your answer
Answer:
4x+1
Step-by-step explanation:
The area is 12x2 + 3x in
The length is 3x
Formula is A=L*B
12x2 + 3x=3x*B
Divide both side by 3x
12x2+3x divide by 3x=B
4x+1=B
The express for the width is 4x+1

Complete question :
Of all the registered automobiles in a city, 11% fail the emissions test. Twelve automobiles are selected at random to undergo an emissions test. Round the answers to four decimal places.
1.)Probability that exactly 3 fail
2.) Fewer Than 3 fail
Answer:
0.1026 ;
0.8623
Step-by-step explanation:
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
p = 0.11
1 - p = 1 - 0.11 = 0.89
n = 12
P(x = 3) = 12C3 * 0.11^3 * 0.89^0
P(x = 3) = 0.1026
Fewer Than 3
P(x < 3) = p(x = 0) + p(x = 1) + p(x = 2)
Using a binomial probability calculator :
P(x = 0) = 0.2470
P(x = 1) = 0.3663
P(x = 2) = 0.2490
(0.2470 + 0.3663 + 0.2490) = 0.8623

Answer:
Step-by-step explain to solve for the maximum area, the first derivative should be solved and equate it to zero, then solve for x.
A = 37x - x^2
dA / dx = 37 - 2x
equate dA / dx = 0
0 = 37 - 2x
2x = 37
x = 37 / 2
x = 18.5 ft
so the maximum area is
A = 37x - x^2
A = 37( 18.5) - 18.5^2
A = 342.25 sq ft
so the answer is letter B

The lengths of the sides of triangle XYZ are written in terms of the variable m, where m ≥ 6. Triangle X Y Z is shown. The length of side X Y is m + 8, the length of side Y Z is 2 m + 3, the length of side Z X is m minus 3. Which is correct regarding the angles of the triangle? mAngleX < mAngleZ < mAngleY mAngleY < mAngleZ < mAngleX mAngleY < mAngleX < mAngleZ mAngleZ < mAngleY < mAngleX
Answer:
mAngleY < mAngleZ < mAngleX
Step-by-step explanation:
Since m ≥ 6
Let's assume m = 7
XY = m + 8 = 7 + 8 = 15
YZ = 2 m + 3 = 2(7) + 3 = 17
ZX = m - 3 = 7 - 3 = 4
When solved, the angles of the triangle are given below;
∠X = 113.58
∠Y = 12.45
∠Z = 53.97
Arranging in order;
∠Y < ∠Z < ∠X
The correct option is;
mAngleY < mAngleZ < mAngleX
