Which of the following is the correct expansion of (x + 3)(x + 4)?
Answer:
(x + 3)(x + 4)
x(x+4)+3(x+4)
[tex] {x}^{2} + 4x + 3x + 12[/tex]
[tex] {x}^{2} + 7x + 12[/tex]
Answer:
It's x2 + 7x + 12 by added the two X at the start then added 3 + 4 to get 7 then 3×4 to get 12
A research team conducted a study showing that approximately 20% of all businessmen who wear ties wear them so tightly that they actually reduce blood flow to the brain, diminishing cerebral functions. At a board meeting of 15 businessmen, all of whom wear ties, what are the following probabilities?
(a) at least one tie is too tight
(b) more than two ties are too tight
(c) no tie is too tight
(d) at least 13 ties are not too tight
Answer:
b) more than two ties are too tight
Step-by-step explanation:
20% of 15
15 = 100%
x = 20%
100x = 15 * 20
x = 300/100
x = 3
ps: I always wear my tie loose at any circumstance, guess I'll never be a good businessman with reduced blood flow to the brain =/

Answer:
She can make 18 bows.
Step-by-step explanation:
0.4 x 18 = 7.2, and you cannot go over since she only has a supply of 7.5.

Find values of x and y.
(x +12)/yº
114
9514 1404 393
Answer:
x = 54
y = 114
Step-by-step explanation:
The angle marked y° corresponds to the one marked 114°. Corresponding angles in this geometry are congruent, so ...
y = 114
__
The angle marked (x+12)° and the one marked y° form a linear pair, so are supplementary:
(x +12)° +114° = 180°
x +126 = 180 . . . . . . . . divide by °, collect terms
x = 54 . . . . . . . . . . . . subtract 126
Write the equation of the line, given the y and x-intercepts. a x-intercept = –68, y-intercept = –34
Answer:
In slope-intercept form, y = -17/34 - 34
Step-by-step explanation:
For the two points, you have (-68, 0) and (0, -34). To get the slope, you take (y-y) / (x-x). Stay consistent on the order you do those. After I did (-34 - 0) / (0 - 68), simplified it, and got a slope of -17 / 34. You are already given the y-intercept, so you just write the equation from there (y = -17/34 - 34)
plzzzzzz help meeeee
Answer:
Step-by-step explanation:
For A, 7x=21, it is asking, 7 multiplied by what number is 21? We can try to figure it out. Let's start with 0.
7(0)≠21
Then 1.
7(1)≠21
7(2)≠21
7(3)=21
Therefore, for question a, the answer is 3.
For question b, it's asking 6 minus what is 2.
With this one, we can say it is 4, since 6-4=2.
Now moving on to B.
a) 2x+4=16
We need to isolate x in order to find it's value.
So we can begin with subtracting 4 from both sides, getting us:
2x=12
Then, if we divide both terms by 2, we get x.
x=12/2
x=6.
b)
3 x (z/4)=9
Again, we need to isolate z.
So, we multiply both sides by 4, getting us
3z=36
then we divide by 3
z=36/3
z=12
c) 16-x=2
Here we simply subtract 16 from each side, then flip the signs to get positive x.
So, 16-x=2
-x=-14
x=14
d) 4k=20
This is essentially asking, 4 times what number is 20?
So we can divide both sides by 4 and get
k=20/4
k=5
Please help i will give 100 points
First:
X = 15
Step-by-step explanation:
So the two angles are congruent, or they are the same angle. So you write the equation as 5x + 9 = 84.
5x + 9 = 84
-9 -9
5x = 75
(divide) 5 from both sides
x = 15
Second:
X = 27
Step-by-step explanation:
For this one I believe the answer is X = 27 because both equations should equal 180 degrees.
So you write the final equation:
(x + 72) + (3x) = 180
-72 -72
(combine X's):
4x = 108
Divide both sides by 4
X = 27
Third:
X = 40
Step-by-step explanation:
For this one, the angles match again, so you write it s:
4x - 50 = 2x + 30
+50 +50
4x = 2x +80
-2x -2x
2x = 80
Divide both sides by 2
X = 40
End

Step-by-step explanation:
Use the y- and x- intercepts to write the equation of the line. y-intercept (0, -6), x-intercept (-2, 0)
Hi there! :)
We are given 2 points. It means we can use the following formula to find the slope:
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
m=[tex]\frac{0-(-6)}{-2-0\\} \\\frac{0+6}{-2}\\\frac{6}{-2} \\-3[/tex]
So the slope is -3
First, let's write the equation of the line in point-slope form.
y-y1=m(x-x1)
y-(-6)=-3(x-0)
y+6=-3(x+0)
y+6=-3x+0
y=-3x+0-6
y=-3x-6

Step-by-step explanation:
by calculator..
or you can do these steps
1/4(4t-9)=1/8(t+9) "divided l.h.s and r.h.s by ⅛"
2(4t-9)=t+9.

Answer:
The amount is $18548.38 and the interest is $2548.38
Steps for solution:
First you want to use the formula A=P(1+[tex]\frac{r}{n}[/tex])^n*t. A= total amount, P= principle or amount of money deposited, r= annual interest rate, n= number of times compounded per year. and t= time in years. In the problem we have P= $16000, r= 3%, n= 1 and t= 5 years. The first picture is the formula used to find the total amount. After we use the formula A=P+I, since A=18548.38 and P=16000. The second picture represents the interest after 5 years.

The admission fee at an amusement park is $6.50 for children and $15.00 for adults. On a certain day, 337 people entered the park, and the admission fees collected totaled $3,423.00. How many children and how many adults were admitted?
Answer:
192 children and 145 adults were admitted.
Step-by-step explanation:
Let c represent the amount of children and let a represent the amount of adults.
Total fees for children = (Fee for one child) x (Amount of children) = 6.5c
Total fees for adults = (Fee for one adult) x (Amount of adults) = 15a
Total fees = Total fees for children + Total fees for adults
3423 = 6.5c +15a
We know that the amount of people who entered the park was 337. Therefore a+c=337, which means a=337-c.
Sub this in to the equation above to get:
3423 = 6.5c +15 (337-c)
3423 = 6.5c + 5055 - 15c
-1632 = -8.5c
c = 192
So there were 192 children.
Since a=337-c and c=192, a=337-192=145. So there were 145 adults.

solve the following inequality for n -5n+6≥-7(5n-6)-6n
Answer: The inequality is: n ≥ 36/37
Step-by-step explanation:
Let's solve your inequality step-by-step.
n − 5n + 6 ≥ −7(5n−6)−6
----------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the inequality.
−4n + 6 ≥ −41n + 42
----------------------------------------------------------------------------------------------------------------
Step 2: Add 41n to both sides.
−4n + 6 + 41n ≥ − 41n+ 42 + 41n
37n + 6 ≥ 42
----------------------------------------------------------------------------------------------------------------
Step 3: Subtract 6 from both sides.
37n + 6 − 6 ≥ 42 − 6
37n ≥ 36
----------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by 37.
37n/37 ≥ 36/37
n ≥ 36/37
----------------------------------------------------------------------------------------------------------------
Answer:
n ≥ 36/37
