2x+4(2x+7)=3(2x+4)
2x+8x+28=6x+12
10x+28=6x+12
4x+28=12
4x=-16
x=-4
Answer:
4x²+20x+16=0
Step-by-step explanation:
First we can expand the right side:
[tex](2x+4)(2x+7) = 4x^{2} +8x+14x+28[/tex]
Simplify:
[tex]4x^{2} +26x+28[/tex]
Now we can expand the left side:
[tex]3(2x+4) = 6x+12[/tex]
Now we equate both of them to each other:
[tex]4x^{2} +26x+28= 6x+12[/tex]
To make this into a quadratic form we can subtract 6x+12 from both sides:
[tex]4x^{2} +26x+28 - (6x+12) = 6x+12- (6x+12)[/tex]
Simplify
[tex]4x^{2} +20x+16 = 0[/tex]
This is the equation in most simplified version.

you invest 5,000 in a bank for 2 years at a 3% interest rate.
Answer:
If simple interest: $5,300
If compounding interest: $5,304.50
Step-by-step explanation:
**As you haven't specified if the interest is simple or compounding, I have provided both**
Simple interest[tex]\sf Formula:A = P(1 + rt)[/tex]
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:
P = 5000r = 3% = 0.03t = 2Substituting the given values into the formula and solving for A:
[tex]\implies \sf A = 5000(1 + 0.03 \cdot 2)[/tex]
[tex]\implies \sf A = 5000(1.06)[/tex]
[tex]\implies \sf A = 5300[/tex]
Compound interest[tex]\sf Formula:A=P(1+\frac{r}{n})^{nt}[/tex]
where:
A = final amountP = principalr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = 5000r = 3% = 0.03n = 1t = 2Substituting the given values into the formula and solving for A:
[tex]\implies \sf A=5000(1+\frac{0.03}{1})^2[/tex]
[tex]\implies \sf A=5000(1.03)^2[/tex]
[tex]\implies \sf A=5304.5[/tex]
Mya and Ashley are buying tickets to the art show. Adult
tickets cost $3 more than the student tickets. Mya buys 7
tickets and 6 adult tickets. Ashley buys 15 student tickets and
1 adult ticket. They both spend the same amount of money
on their tickets. What is the price of one adult ticket?
Answer:
$8
Step-by-step explanation:
a: adult tickets
s: student tickets
Mya: 7s + 6(3+s)
Ashley: 15s + 1(3+s)
Mya: 7s + 6(3+s) –> 7s + 18 +6s –> 13s +18
Ashley: 15s + 1(3+s) –> 15s + 3 + s –> 16s +3
13s + 18 = 16s +3
15 = 3s, divide 3 from both sides so s = 5
so students tickets cost $5
since adult tickets cost $3 more than student tickets:
($3 + $5) = $8 for an adult ticket.

the answer is $8

with these numbers i need to round to the nearest dollar (SHOW WORK PLS) estimate total cost.
Answer:
$10
Step-by-step explanation:
1.24+6.43+2.13= 9.8
9.8 rounded to the nearest dollar is $10.
You can do it a different way, rounding the numbers before adding.
this would be:
1.3+6.4+2.1= 9.8
Either way, you get the same number. 9.8
And 9.8 rounded to the nearest dollar is $10
All the best, -Crispin
Answer:
$1.00
$6.00
$2.00
The estimated cost is $9.00
Step-by-step explanation:
1.24 = The 2 in 1.24 is smaller than 5 so you round down
6.43 = The 4 in 6.43 is smaller than 5 so you round down
2.13 = The 1 in 2.13 is smaller than 5 so you round down

Check the picture below, so the hyperbola looks more or less like so, hmmm so is a vertical one, so is opening towards the y-axis, meaning the fraction that is positive is the one with the y-variable, its traverse axis length is 4 units, from +2 to -2, meaning that a = 2, and the distance either focus to the center is √5, so
[tex]\textit{hyperbolas, vertical traverse axis } \\\\ \cfrac{(y- k)^2}{ a^2}-\cfrac{(x- h)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h, k\pm a)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{ a ^2 + b ^2} \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} h=0\\ k=0\\ a=2\\ c=\sqrt{5} \end{cases}\qquad \cfrac{(y- 0)^2}{ 2^2}-\cfrac{(x- 0)^2}{ b^2}=1[/tex]
[tex]\sqrt{5}=\sqrt{2^2+b^2}\implies 5=4+b^2\implies 1=b^2\implies \sqrt{1}=b\implies 1=b \\\\[-0.35em] ~\dotfill\\\\ \cfrac{(y- 0)^2}{ 2^2}-\cfrac{(x- 0)^2}{ 1^2}=1\implies \cfrac{y^2}{4}~~ - ~~x^2~~ = ~~1[/tex]
Let Tn, be the number of dots in figure.
How many dots are there in figure 30?
Look at the picture (don't mind of the highlighted ones).
Answer:
4294967293 dots
Step-by-step explanation:
Figure 1 has 5 dots.
Figure 2 has 13 dots.
Figure 3 has 29 dots.
Subtract and find different of each term:
13-5 = 829-13 = 16Let [tex]\displaystyle \large{b_n}[/tex] be sequence of difference (and the sequence appears to be geometric.)
So for [tex]\displaystyle \large{b_n}[/tex], find the common ratio which is 2.
Hence, [tex]\displaystyle \large{b_n = 8(2)^{n-1}}[/tex] - recall geometric sequence formula below:
[tex]\displaystyle \large{a_n = a_1r^{n-1}}[/tex]
The sequence of difference [tex]\displaystyle \large{b_n=8(2)^{n-1}}[/tex] can be simplified to:
[tex]\displaystyle \large{b_n=2^3(2)^{n-1}}\\\displaystyle \large{b_n=2^{n+2}}[/tex]
Now to find the original sequence:
[tex]\displaystyle \large{a_n = a_1 + \sum_{k=1}^{n-1}b_k}[/tex]
Hence:
[tex]\displaystyle \large{T_n=5+\sum_{k=1}^{n-1}8(2)^{k-1}}[/tex]
Recall:
[tex]\displaystyle \large{\sum_{k=1}^{n-1} a_1r^{n-1} =a_1\left( \dfrac{1-r^{n-1}}{1-r}\right)}[/tex]
Therefore:
[tex]\displaystyle \large{T_n=5+\sum_{k=1}^{n-1}8(2)^{k-1}}\\\displaystyle \large{T_n=5+8\left(\dfrac{1-2^{n-1}}{1-2}\right)}\\\displaystyle \large{T_n=5+8\left(\dfrac{1-2^{n-1}}{-1}\right)}\\\\\displaystyle \large{T_n=5+8(-1+2^{n-1})}\\\displaystyle \large{T_n=5-8+8(2)^{n-1}}\\\displaystyle \large{T_n=2^{n+2}-3}[/tex]
Therefore, the sequence for 5,13,29 is [tex]\displaystyle \large{2^{n+2}-3}[/tex].
Therefore, in figure 30:
[tex]\displaystyle \large{T_{30}=2^{30+2}-3}\\\displaystyle \large{T_{30}=2^{32}-3}\\\displaystyle \large{T_{30}=4294967293}[/tex]
Therefore, there are 4294967293 dots in figure 30
