We have the equation [tex]\sf -11=t-5}[/tex]. And what we need to do is solve for the variable, t.
↪
To solve for the variable, we should ensure that the variable we need to solve for is all by itself on one side of the equation.
T is not all by itself, [tex]\because[/tex] 5 is subtracted from it.
So what do we do to "remove" that 5 from there? Wouldn't it be great if there was a zero instead of the -5?
We can make that happen by adding 5 to both sides.
We add 5.
[tex]\sf -11=t-5+5}\\-11=t+0}\\-11=t[/tex]
[tex]\bullet[/tex] However, we also need to add 5 to the other side.
[tex]\sf -11+5=t}[/tex]
Simplify!
[tex]\sf -6=t}[/tex]
NOW the variable, t, is all by itself.
↪
Tip: Why not check your work and make sure there are no mistakes?
We can proof-read, but we can also do this:
Plug in the solution (t=-6) into the original equation.[tex]\sf -11=-6-5}[/tex]. Upon simplification, we obtain
[tex]\sf -11=-11[/tex]
Since both sides (the left hand side, l.h.s. and the right hand side, r.h.s. are the same, our solution, t=-6, is correct. Great job!

Given the following data points, calculate the curve of best fit. Show all steps.
The equation of curve of best fit is y = -30.17x + 14.49. To find the curve of best fit, we would require two equations which are explained in details below.
Equation of Straight LineData;
∑x = 16∑y = 50.9∑x^2 = 35∑xy = 24.6The equation of straight line is y = ax + b
If we modify it to fit into this problem,
[tex]\sum y = na + b \sum X ... equ(i)\\\sum xy = a \sum x + b \sum x^2 ...equ(ii)[/tex]
Let's substitute the values into the equations and solve
[tex]\sum y = na + b \sum X ... equ(i)\\\sum xy = a \sum x + b \sum x^2 ...equ(ii)\\50.9 = 6*a + b*16 ...equ(i)\\24.6 = a*16 + b*35 ...equ(ii)\\50.9 = 6a + 16b ...equ(i)\\24.6 = 16a + 35b ...equ(ii)[/tex]
Let's solve both equation (i) and equation (ii)
[tex]50.9 = 6a + 16b...equ(i)\\24.6 = 16a + 35b ...equ(ii)\\a = -30.17, b = 14.49[/tex]
We can substitute the values of a and b into the equation
[tex]y = ax + b\\y = -30.17x + 14.49[/tex]
The equation of curve of best fit is y = -30.17x + 14.49

Circle A has center of (2, 3) and a radius of 5, and circle B has a center of (1, 4) and a radius of 10. What steps will help show that circle A is similar to circle B?
Dilate circle A by a scale factor of 2.
Translate circle A using the rule (x + 1, y − 1).
Rotate circle A 180° about the center.
Reflect circle A over the y-axis.
Answer:
A
Step-by-step explanation:
To show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have two circles:
Circle A has a center of (2, 3) and a radius of 5
Circle B has a center of (1, 4) and a radius of 10
The standard circle's equation can be written as:
(x - h)² + (y - k)² = r²
The equation for circle A:
(x - 2)² + (y - 3)² = 5²
The equation for circle B:
(x - 1)² + (y - 4)² = 10²
To show that circle A is similar to circle B:
It is required to perform the geometric transformation:
Dilate circle A by a scale factor of 2.
The radius of circle A is 5 units and after dilation by a scale factor of 2, the radius of the circle becomes 10 which is the radius of circle B.
Thus, to show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

Mr. blue's first year salary is $30,000 and it doubles each year. what is the explicit rule for the sequence in simplified form?
Answer: Explicit Rule: a_n=30,000 • 2^n-1
Recursive Rule: a_n = 2a_n-1; a_1 = 30,000
Step-by-step explanation: the explicit rule for a geometric sequence is a_n = a_1 • r^n-1 and the recursive rule is a_n= r • a_n -1.
a_1 is the first term of the sequence, which is this case is 30,000. R is the common ration, which is 2 since it doubles each time. Substitute those numbers into the formulas and that’s what you’ll get. Hope this helps. God bless you!!!

X = 7.8
Step-by-step explanation:
First I will mark all the Information given to us:
Angle 1: 52 Degrees
Angle 2: 90 (Marked by the box) Degrees
Angle 3: 180-(90+52) Triangle Angle Sum Therom
Simplified Angle 3: 38 Degrees
Height: 10
Base: X
Hypo: ? (we will call this y)
In order to solve this problem we must use basic trig functions such as sin, cos and tan.
I will be applying sin for the degree measure of 52 as it is applicable there.
(Sin for refrence sin(angle measure)= side opposite to angle/hypo)
So this would be in our case:
Sin(52)=10/y
Simplify
y sin(52) = 10
y = 10/sin(52) (use a calculator make sure sin is in degrees not radians)
y=10/0.78801
y=12.69018 (We have our hypo value)
We can now apply a²+b²=c²
a²+10²=12.69018²
a²+100=161.040668432 (Calculator)
a²=61.040668432
a=√61.040668432 (calculator)
a=7.81285277168

How to determine the equation of the line?To determine the equation of the line, we need to determine the slope and the y-intercept. Then, we will substitute the slope and the y-intercept in the slope intercept form equation to obtain the equation in slope intercept form.
Slope of line:Two points that lie on line: (0, 3) and (-5, 0)
[tex]\implies \text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

From 2017 to 2018, owner’s equity for commercial banks changed by $_ billion (round your answer to two decimal places)
Answer:
Borrowings = $0.10 Billion
Owner's Equity = $0.40 Billion
Step-by-step explanation:
Total liabilities = deposits + borrowings
Borrowings = total liabilities - deposits
Borrowings in 2017 = $14.60 - 11.90 = $2.70 billion
Borrowings in 2018 = $14.80 - $12.20 = $2.60 billion
Borrowings from 2017-2018= 2.60 - 2.70 = $0.10 billion
Owner's Equity= total assets - total liabilities
Owner’s equity in 2017 = $16.2 - $14.6 = $1.6 billion
Owner’s equity in 2018 = $16.8 - $14.8 = $2 billion
Owner's Equity from 2017-2018= 2 - 1.6 = $0.4 billion
Hope this helps!
The Owner's Equity for commercial banks in 2017-2018 is $0.4 billion.
The given is,
Borrowings = $0.10 Billion
Owner's Equity = $0.40 Billion
What is the formula for the total liabilities?Total liabilities = deposits + borrowings
So we have Borrowings = total liabilities - deposits
Borrowings in 2017
= $14.60 - 11.90
= $2.70 billion
Borrowings in 2018
= $14.80 - $12.20
= $2.60 billion
Borrowings from 2017-2018
= 2.60 - 2.70
= $0.10 billion
Owner's Equity= total assets - total liabilities
Owner’s equity in 2017
= $16.2 - $14.6
= $1.6 billion
Owner’s equity in 2018
= $16.8 - $14.8
= $2 billion
Owner's Equity from 2017-2018
= 2 - 1.6
= $0.4 billion

3x + 3y = 18
5x + 3y = 28
Answer:
(5, 1 )
Step-by-step explanation:
3x + 3y = 18 → (1)
5x + 3y = 28 → (2)
subtract (1) from (2) term by term to eliminate y
(5x - 3x) + (3y - 3y) = 28 - 18
2x + 0 = 10
2x = 10 ( divide both sides by 2 )
x = 5
substitute x = 5 into either of the 2 equations and solve for y
substituting into (1)
3(5) + 3y = 18
15 + 3y = 18 ( subtract 15 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1

[tex]3 \frac { 1 } { 4 } + 1 \frac { 2 } { 5 }\\= \frac{13}{4}+\frac{7}{5}\\ \\\mathrm{LCM = 20}\\\\= \frac{65}{20}+\frac{28}{20} \\=\boxed{\bf\: \frac{93}{20}=4.65}[/tex]
