What’s the answer for this one??
Answer:
It is the second one.
Step-by-step explanation:
a and e are equal because they are mirrored. d and b are equal because they are on the same line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.
which of the following includes two constant terms in three variables ?
[tex]a \: \ 4xy + 2 + 3a - 1[/tex]
[tex] \: \: \: b \: 22 - 11b - 4a + 1[/tex]
pls help
Answer:
a is the answer as it has 2 constant terms in 3 variables
Step-by-step explanation:
constant means a no. (it doesnt changes)
ex. 2 , 7 etc
variable means a term (generally a letter) which changes, its value will differ.
in the equation you have given both have only 2 variables
have you posted all the options?
GOOD LUCK FOR THE FUTURE! :)

What is the equation of a line that has slope = -4 and y-intercept is (0, 3)?
Answer: y = -4x + 3
Step-by-step explanation:
y = mx + b
=> y = -4x + b
Find "B":
y = -4x + b
=> 3 = -4(0) + b
=> b = 3
so y = -4x + 3

solve for x...................................................................................
Answer:
x = 36°
Step-by-step explanation:
x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
5x = 200° - 20°
5x = 180°
x = 180° / 5
x = 36°
Hope it will help :)
Consider the line x-2y=-1 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
Answer:
slope of line that is parallel is 1/2
slope of line that is perpendicular is -2
Step-by-step explanation:
parallel lines have the same slope
perpendicular lines have slopes that are opposite and reciprocal
x - 2y = -1
-2y = -x -1
y = 1/2x + 1/2
the coefficient of the 'x' term represents the slope

Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year. What is the annual sales after 7 years?
Answer:
Around $855,355.66
Step-by-step explanation:
In these type of problems, you'd use the following equation
[tex]Initial Value * (percentage)^{x}[/tex]
Since the revenue's increasing by 4% every year, you'd plug 104/100 in the percentage box. X is the ammount of times the percentage is applied, so it would be 7, since we're finding the sales after 7 years. Finally, 650000 goes into the initial value and yeah. After calculating, you'll get around $855,355.66

A store manager purchased hoodies for $24.99 apiece. He sells the hoodies for $32. What is the markup percentage?
Given:
A store manager purchased hoodies for $24.99 apiece.
He sells the hoodies for $32.
To find:
The markup percentage.
Solution:
We have,
Cost price (C.P.) = $24.99
Selling price (S.P.) = $32
We know that,
[tex]\text{Markup percentage}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]
[tex]\text{Markup percentage}=\dfrac{32-24.99}{24.99}\times 100[/tex]
[tex]\text{Markup percentage}=\dfrac{7.01}{24.99}\times 100[/tex]
[tex]\text{Markup percentage}=\dfrac{701}{24.99}[/tex]
[tex]\text{Markup percentage}\approx 28.05[/tex]
Therefore, the markup percentage is 28.05%.

A 34 foot flag pole is casting a shadow that is 17 feet long. How far is the top of the flag pole from the the end of the shadow?
Answer:
17*square root of 5
Step-by-step explanation:
Form a triangle like the one shown below and use the pythagorean theorem:
[tex]17^2+34^2=c^2\\289+1156=c^2\\1445 = c^2\\c = \sqrt{1445} \\c = 17\sqrt{5}[/tex]
Stella is making 25 sundaes with mint, chocolate, and vanilla ice cream. 1 5 of the sundaes are mint ice cream and 1 2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?
Answer:
Vanilla = 10 sundaes
Step-by-step explanation:
Total sundaes = 25
1/5 of the sundaes are mint ice cream
Mint ice cream = 1/5 of 25
= 1/5 * 25
= 25/5
= 5
Sundaes remaining = total sundaes - sundaes for mint ice cream
= 25 - 5
= 20 sundaes
Sundaes remaining = 20 sundaes
1/2 of the remaining sundaes are chocolate
= 1/2 of 20
= 1/2 * 20
= 20/2
= 10
Chocolate ice cream = 10
The rest will be vanilla
Sundaes remaining = 20 - 10
= 10 sundaes
Vanilla = 10 sundaes

A baseball team had 70 players show up for tryouts last year and this year had 85 players show up for tryouts. Find the percent increase in players from last year to this year.
Answer:percent increase in players from last year to this year= 7.14%
Step-by-step explanation:
percent increase = (Increase in number of players /Initial value of players Last year) x 100
value of players for tryouts last year = 70
value of players for tryouts this year = 85
Increase in tryouts = 85-70 =5
percent increase = 5/70 x 100
= 7.14%
Write an explicit formula for the nth term of this sequence:
6, 11, 16, 21, . . .
1. an=5n+11
2. an=5n+1
3. an=21-5n
4. an=6n+1
Answer:
2)an = 5n + 1
Step-by-step explanation:
This is an arithmetic series.
6 , 11 , 16, 21 ,.....
First term = [tex]a_{1}[/tex] = 6
Common difference = d = second term - first term
= 11 - 6 = 5
nth term = [tex]a_{1}+(n-1)*d[/tex]
= 6 + (n - 1) * 5
= 6 + n * 5 - 1*5
= 6 +5n - 5
= 6 - 5 + 5n
= 1 + 5n
