of a football team's season touchdowns, about 43% came by passing. If the team scored 28 touchdowns, how many were by other means?
43% were from passing so 100% - 43% = 57% came by other means.
28 x 57% = 28 x 0.57 = 16
16 came from different means.

Given the equation find the y-intercept. Write it as a coordinate ( 0 , y ).
y=-4x+3
Answer:
(0, 3)
Step-by-step explanation:
The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).
Answer:
y=3
Step-by-step explanation:
Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.

What is a formula for the nth term of the given sequence?
36, -48, 64...
Answer:
A formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Step-by-step explanation:
Given the sequence
36, -48, 64...
We know that a geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Compute the ratios of all the adjacent terms
[tex]\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-\frac{4}{3}[/tex]
Therefore, the given sequence is a geometric sequence.
As the first element of the sequence is
[tex]a_1=36[/tex]
so substituting [tex]a_1=36[/tex] and [tex]r=-\frac{4}{3}[/tex] in the nth term
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Therefore, a formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Boden's account has a principal of $300 and a simple interest rate of 3.8%. Complete the number line. How much money will be in the account after 4 years, assuming Boden does not add or take out any money?
Answer:$66.00
Step-by-step explanation:
first we need multiply :D I will use the formula I =prt
principal= $500
rate=3.3%
time= 4 years
but we need to convert the percent, 3.3%, to a decimal
3.3%=0.033 or .033
then we multiply
500 × 0.033 × 4 = 66 = $66.00

The terms in the sequence decrease by the same amount each time:
9, 6 ,3 ,0, -3, -6
Work out ,in term of n, the nth term of the sequence
Answer:the nth term of the sequence, Tn= -3n +12
Step-by-step explanation:
The nth term of an arithmetic progression is given as
Tn= a+ (n-1) d
where a= first term
and d = common difference
In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that the number is decreasing by 3
The first term, a= 9
and common difference, d = -3
using our formulae
Tn= a+ (n-1) d
Tn= 9 + ( n-1) -3
Tn=9- 3n+ 3
Tn= -3n +12
1. E = -20,000p + 90,000
R = -2,170p2 + 87,000p
The equations of E and R are illustrations of cost and revenue functions
The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
How to determine the break even pointThe cost and the revenue functions are given as:
E = -20,000p + 90,000
R = -2,170p^2 + 87,000p
At the break even point, we have:
E = R
Substitute known values
-20,000p + 90,000 = -2,170p^2 + 87,000p
Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

3. Given the statement "x - 4 is a factor of f(x)= 5x* – 22x - 2x2 – 25x +4". explain how to verify the
statement is accurate.
Step-by-step explanation:
x - 4 = 0
=> x = 4
f(x)= 5x – 22x - 2x² – 25x +4
By remainder theorem,
f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4
= 20 - 88 - 32 - 100 + 4 ≠ 0
Since the remainder is not 0, x - 4 is not a factor.

Every three years the population of one part of Brooklyn is recorded.
In 2014 there was a population of 10,500 people.
From 2014 to 2017 the population increased by 22%.
From 2017 to 2020 the population decreased by 10%.
What was the population of this area in 2020?
Answer:
11,529
Step-by-step explanation:
10500x22%=2310
10500+2310=12810
12810x10%=1281
12810-1281=11529
Answer:
Hello there!
Your question asks to find what was the size of the population in 2017
Answer: 6,721
In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.
Key information:
In 2010, population was 6500
In 2014, population increased by 10% from 2010
In 2017, population decreased by 6% from 2014.
With the information above, we can solve the problem.
We're going to start with 6500 as our starting population.
We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

Karla is selling tickets for a high school play. Child tickets cost $7 and adult tickets cost $13 she sells 180 tickets and collects $1830 Setup a system of equations using C for number of child tickets and A for number of adult tickets to find the number of each ticket sold
Answer: The number of child tickets is 85 and the number of adult tickets is 95.
Step-by-step explanation:
Let C = Number of child tickets
A = Number of adult tickets.
As per given, we have
C+A=180 (i)
7C+13A=1830 (ii)
Multiply 7 to both sides of equation (ii), we get
7C+7A=1260 (iii)
Eliminate (iii) from (ii) , we get
[tex]6A=570\\\\\Rightarrow\ A=95[/tex]
Put value of y in (i), we get
C= 85
Hence, the number of child tickets is 85 and the number of adult tickets is 95.
