Answer:
x = 20
Step-by-step explanation:
2x + 20 = 3x
2x - 2x + 20 = 3x - 2x
20 = x
2x + 20 = ?
2(20) + 20 = ?
40 + 20 = ?
60 = ?
3x = ?
3(20) = ?
60 = ?

A person invests 9000 dollars in a bank. The bank pays 4.75% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 12600 dollars?
A=P(1+nr)nt
Answer:
The time required to get a total amount of $ 12,600.00 from compound interest on a principal of $9000 at an interest rate of 4.75% per year and compounded 4 times per year is 7.1 years.
Step-by-step explanation:
Given
Principle P = 9000 dollars
Rate r = 4.75% = 0.0475
Total Amount A = 12600 dollars
compounded quarterly n = 4
To determine:
Time t = ?
Using the equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
solving the equation for 't'
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(12,600.00/9,000.00) / ( 4 × [ln(1 + 0.011875/4)] )
t = 7.1 years
Therefore, the time required to get a total amount of $ 12,600.00 from compound interest on a principal of $9000 at an interest rate of 4.75% per year and compounded 4 times per year is 7.1 years.

At a basketball game, 65% were supporting the home team, while 35% were supporting the visiting team. If 882 attending the game supported the visiting team, what was the total number of people at the game
Answer: 2520
Step-by-step explanation:
Given: Number of people supported the visiting team = 882
Let x = Total number of people at the game.
As per given,
35% of x = 882 [35% were supporting the visiting team]
[tex]\Rightarrow\ 0.35x=882\\\\\Rightarrow\ x=\dfrac{882}{0.35}\\\\\Rightarrow\ x= 2520[/tex]
Hence, the total number of people at the game = 2520 .

For 2), we have;
325 Towers/(6.25 thousands customers) = 52 Towers/(Thousand customer)
For 3), we have;
377 Towers/(7.25 thousands customers) = 52 Towers/(Thousand customer)
For 4), we have;
481 Towers/(9.25 thousands customers) = 52 Towers/(Thousand customer)
Therefore, the ratios of towers to customers (thousands) all have the same equivalent unit rate of 52 Towers/(thousand customers).

A parabola can be drawn given a focus of (4, -3) and a directrix of y=5 Write the equation of the parabola in any form.
Answer:
The equation of the parabola is (x - 4)² = -16(y - 1)
Step-by-step explanation:
The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where
The vertex of the parabola is (h, k)The focus is (h, k + p)The directrix is at y = k - p∵ The focus of the parabola is (4, -3)
∵ The focus is (h, k + p)
∴ h = 4
∴ k + p = -3 ⇒ (1)
∵ It has a directrix of y = 5
∵ The directrix of the parabola is y = k - p
∴ k - p = 5 ⇒ (2)
→ Add equations (1) and (2) to find k and p
∵ (k + k) + (p - p) = (-3 + 5)
∴ 2k + 0 = 2
∴ 2k = 2
→ Divide both sides by 2
∴ k = 1
→ Substitute the value of k in equation (1)
∵ 1 + p = -3
→ Subtract 1 from both sides
∴ 1 - 1 + p = -3 - 1
∴ p = -4
∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)
→ Substitute the values of h, k, p in it
∴ (x - 4)² = 4(-4)(y - 1)
∴ (x - 4)² = -16(y - 1)
∴ The equation of the parabola is (x - 4)² = -16(y - 1)

Find the coordinates on f the point where y-4x=1 crosses the axis
Answer:
The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]
Step-by-step explanation:
Intercepts of a Function
Given a function y=f(x), the intercepts with the x-axis, if any, can be found by solving the equation:
y = f(x) = 0
The intercepts with the y-axis can be found by calculating
f(0)
We are given the function
y - 4x = 1
To find the x-intercepts, set y=0:
0 - 4x = 1
Solving:
[tex]x = -\frac{1}{4}[/tex]
For x=0:
y - 4*0 = 1
y = 1
The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]
