question 1A.) 4, 8, 12B.)6, 10, 26C.) 2, 6, 22D.) 1, 2, 6
Answer
Option C is correct.
a₁, a₂ and a₃ = 2, 6 and 22 respectively.
Explanation
We have been told that
a₀ = 1
And any term after that is given as
[tex]a_{i+1}=4a_i-2[/tex]So,
a₁ = 4a₀ - 2
a₁ = 4 (1) - 2
a₁ = 4 - 2
a₁ = 2
a₂ = 4a₁ - 2
a₂ = 4 (2) - 2
a₂ = 8 - 2
a₂ = 6
a₃ = 4a₂ - 2
a₃ = 4 (6) - 2
a₃ = 24 - 2
a₃ = 22

Which of the following equations is equivalent to 4x + 2y = 12? A. 2y = -4x + 12 B. y=-2x + 6 C. y = 2X - 6 D. y = 8x + 24
Let's find the equivalent equation to:
4x + 2y = 12
2y = 12 - 4x
Dividng by 2 at both sides:
2y/2 = 12/2 - 4x/2
y = 6 - 2x
We can see that choices B and C are not correct because the signs.
If we multiply by 2 at both sides, we have:
2y = 12 - 4x
We can see that if we change the order at the right side of the equation, we have:
2y = -4x + 12

200,000 divided by 2,800
wich equation is proportional?y=2x-6y=-1/4x
What is the equation for the line in slope-intercept form?
Answer:
y = -2x - 4
Step-by-step explanation:
Slope intercept form : y = mx + b
Where
m = slopeb = y intercept Finding Y - InterceptThe y intercept is the point where the line crosses the y axis.
Here, just by looking at the graph we can say that the y intercept is at (0,-4) because that is where the line passes the y intercept.
This means that b = - 4
Finding the slopeWe can find the slope using the following formula
Slope = (y2-y1)/(x2-x1)
Where, (x1,y1) and (x2,y2) are any given points on the line
The points used can vary however I have chosen (0,-4) and (-2,0)
Defining our variables we get (x1,y1) = (0,-4) and (x2,y2) = (-2,0)
So we have x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0
We now plug this in to the formula
Slope = (y2-y1)/(x2-x1)
==> plug in x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0
Slope = (0-(-4))/(-2-0)
==> remove parenthesis
Slope = (0+4)/(-2-0)
==> simplify addition and subtraction
Slope = 4/-2
==> simplify fraction
Slope = -2
So the slope or "m" is -2
Plugging the y intercept and slope into y intercept formAgain we have y = mx + b
m = slope so m = -2 and b = y intercept so b = -4
Plugging this in, we acquire y = -2x - 4
Last year the book fair sold 200 bookmarks compared to the 180 sold this year. What is the percent of change in the number of bookmarks sold?
Answer:
Step-by-step explanation:
1. Subtract 200 from 180
200 - 180 = 20
2. Divide the difference of the number of bookmarks by last years
20 / 200 = 0.1
3. Multiply 0.1 by 100 to get the percentage
0.1 x 100 = 10 %
4. Since this is a reduction in number of bookmarks sold, then it would be a -10% change in the number of bookmarks sold.
If a loan is taken out for $278 at 10% and costs the borrower $174.12 in simple interest, how many years was the loan for? ROUND YOUR ANSWER TO THE NEAREST WHOLE YEAR
Data:
Loan=$278 at 10%
A simple interest is calculated for payments on the initial capital.
If the total interest was $174.12.
If the interest is on a year. You calculated the interes of one year. The 10% of $278:
[tex]278\cdot\frac{10}{100}=27.8[/tex]In a year the interest is $27.8.
Then, $174.12 divided into $27.8 is the number of years of the loan:
[tex]\frac{174.12}{27.8}=6.26\approx6[/tex]Then, the loan was for 6 years-7t-8=10+2t solve for t
Answer:
t= -2
Step-by-step explanation:
Hope this helps!!
Answer:
t = -2
Step-by-step explanation:
-7t - 8 = 10 + 2t
Subtract 10 from both sides
-7t - 18 = 2t
Add 7t to both sides
-18 = 9t
Divide both sides by 9

What is the measure of angle X to the nearest degree?
Using a trigonometric relation we will see that the correct option is B, 24°.
What is the measure of angle X?On the image we can see a right triangle, where the length of the hypotenuse and of one leg (the opposite cathetus to angle X) are known.
We can use the trigonometric relation:
sin(a) = (opposite cathetus)/(hypotenuse)
Then we can write:
sin(X) = 9/22
If we apply the inverse sine function in both sides, we will get:
X = Asin(9/22) = 24.15°

The answer, the measure of the smallest angle is 39° in the triangle.
What is are of triangle?
The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.
The sum of all angle of triangle = 180
Let x be the smalletst angle
2nd angle will be x+24
and 3rd angle will be 2x
So sum of all angles x+2x+x+24=180

x=156/4
x=39

If she uses the pass 10 times this year then the unit rate in cost per visit is $11 unit per visit.
In the given question,
Annie purchased a season pass for the new aquarium at a cost of $110.
If she uses the pass 10 times this year then we have to find the unit rate in cost per visit.
We have to find the unit rate.
Unit rate means finding the value of one object, that means we have to find the cost of one visit.
The cost of season pass is $110.
She visit aquarium 10 times.
We find the unit rate cost per visit by dividing the total cost of season pass for the new aquarium by total times she visits in the new aquarium.
10 times = $110 cost
Divide by 10 on both side
10/10 times = $110/10 cost
1 times = $11 cost
Hence, if she uses the pass 10 times this year then the unit rate in cost per visit is $11 unit per visit.

Find the domain and range and intercepts.g of x = 3 / x-4
a) Domain; all real numbers except 4
b) Range; all real numbers except y = 0
c) Y-intercept = -0.75
d) x-intercept does not exist
Here, we want to find the domain, range and intercepts
The domain refers to the possible x-values
From the question, the function will hold for all values of x, except x = 4, where we will have an undefined expression
Thus, the domain is all real numbers, except x= 4
For the range, we are referring to the possible y-values
From the given equation the possible y values are all real numbers except y = 0
To find the intercepts, let us write g(x) as y
The equation is thus;
[tex]\begin{gathered} y\text{ = }\frac{3}{x-4} \\ \end{gathered}[/tex]To get x-intercept, substitute y = 0
By doing this, we have no x-intercept
To get the y-intercept, we simply substitute x = 0
That means;
[tex]\begin{gathered} y\text{ = }\frac{3}{0-4} \\ y\text{ = }\frac{3}{-4} \\ y\text{ = -0.75} \end{gathered}[/tex]8373+01274+93738939x937x058+938484

A rectangle has a length of 17 inches less than 7 times its width. If the area of the rectangle is 2204square inches, find the length of the rectangle.
SOLUTION
We are told that the length of the rectangle is 17 inches less than 7 times its width.
Now, let the letter L represent the length and the letter w represent the width of the rectangle.
This statement can be represented algebraically as
[tex]L=7w-17[/tex]So, Area =
[tex]\text{Area = L x w}[/tex]We are also told the Area A of the rectangle = 2204. Now
[tex]\begin{gathered} 2204=L\times w \\ \\ 2204=(7w-17)\times w \end{gathered}[/tex]We have to find the width, then we find the length L
[tex]\begin{gathered} 2204=(7w-17)\times w \\ 2204=7w^2-17w \\ 7w^2-17w-2204=0 \\ \\ \text{Solving the quadratic equation } \\ \\ w=19\text{ or w = -16.57} \end{gathered}[/tex]Since the width cannot be negative, w = 19 inches
The length becomes
[tex]\begin{gathered} L=7w-17 \\ L=7\times19-17 \\ L=133-17 \\ L=116\text{ inches } \end{gathered}[/tex]
