3.) Solve:
5x + 3- 3x = 2(x + 3) - 5
Answer:
0 = -2
Step-by-step explanation:
Answer:
no answer.
Step-by-step explanation:
5x + 3 - 3x = 2(x + 3) - 5 Simplify the left.
2x + 3 = 2(x + 3) - 5 Remove the brackets
2x + 3 = 2x + 6 - 5 Simply the right
2x + 3 = 2x + 1
It doesn't matter what you do, this is going to give you an impossible answer. The 2x's will cancel out and you will get 3 = 1 which is impossible.

What is the next term of the arithmetic sequence?
-2, 3, 8, 13, 18,
Answer:
[tex]\boxed{\boxed{\sf~a_6=23}}[/tex]
Solution Steps:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding 5 to the previous term in the sequence gives the next term. In other words, [tex]a_n=a_1+d(n-1)[/tex].
Arithmetic Sequence: [tex]d=5[/tex]
Find the next term using the Arithmetic Sequence.
Arithmetic Sequence: [tex]a_6=a_5+5[/tex]
[tex]a_6=18+5=23[/tex]

If f(x) = 4x ^ 2 - 6 and g(x) = x ^ 2 - 4x - 8 , find (f - g)(x)
A. (f - g)(x) = 3x ^ 2 - 4x - 2
B. (f - g)(x) = 3x ^ 2 + 4x + 2
C. (f - g)(x) = 5x ^ 2 - 4x - 14
D. (f - g)(x) = - x ^ 2 - 14
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= (4x² - 6) - (x² - 4x - 8)
= 4x² - 6 - x² + 4x + 8
= 3x² + 4x + 2. (B)

Answer:
x = 47°
Step-by-step explanation:
In a kite the main diagonal AC bisects the opposite angles, then
∠ BAE = ∠ DAE = 43° , then ∠ A = 86°
Since AB and AD are congruent then Δ ABD is isosceles and the base angles are congruent, thus
x = [tex]\frac{180-86}{2}[/tex] = [tex]\frac{94}{2}[/tex] = 47°

A historian took a count of the number of people in a Gold Rush town for six years in the 1870's find a quadratic function that models the data as a function of x the number of years since 1870. Use the model to estimate the number of people in the town in 1878
Solution :
The model is :
Year 1870 1871 1872 1873 1874 1875 1876
Population 365 384 393 392 381 360 329
It is given that a historian counted the number of people in the Gold Rush town for a 6 years staring from 1870.
Therefore the quadratic function which models a data as a function of the number of years from 1870 i.e. x is given by
[tex]$P(x) = -5x^2+24x+365$[/tex]
And the number of people present the town of Gold Rush in the year 1878 can be found by using the model is 237.

System of Equations
Solve the following system of equations:
11x + 22y = 88
x = 10 - 3y [2]
By the substitution method.
We can divide the first equation by 11:
x + 2y = 8 [1]
Substitute x from [2] into [1]:
10 - 3y + 2y = 8
Simplifying:
10 - y = 8
Subtracting 10:
-y = -2
Multiplying by -1:
y = 2
From [2]:
x = 10 - 3y
x = 10 - 3*2 = 4
Solution: (4,2)

PLATO Course Math 8, Unit Activity Transformations: Preston says the sequence of transformations that maps triangle ABC onto triangle DEF is: rotate it 180 degrees about the origin, and then translate it up 7 units.
Chanel says the sequence of transformations that maps triangle ABC onto triangle DEF is: reflect it across the x-axis, then reflect it across the y-axis, and then translate it up 6 units and left 1 unit.
Complete a table to find the rule for the rotation, the coordinates of triangle ABC, and the coordinates of the rotated image, triangle A′B′C′. Please put the letter before the coordinates.
Transformation involves changing the position of a shape.
The transformation rule is: [tex]\mathbf{(x,y) \to (-x - 1,-y + 6)}[/tex]
From the graph, we have the following points
[tex]\mathbf{A = (-4,5)}[/tex]
[tex]\mathbf{B = (-3,1)}[/tex]
[tex]\mathbf{C = (-5,2)}[/tex]
First, triangle ABC is reflected across the x and y axes.
So, we have:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
Next, the points are shifted up by 6 units, and left by 1 unit.
So, we have:
[tex]\mathbf{(x,y) \to (-x - 1,-y + 6)}[/tex]
Apply the above transformation rule on ABC, we have:
[tex]\mathbf{C = (4 - 1,-5 + 6) = (3,1)}[/tex]
[tex]\mathbf{D = (3 - 1,-1 + 6) = (2,5)}[/tex]
[tex]\mathbf{E = (5 - 1,-2 + 6) = (4,4)}[/tex]
Hence, the transformation rule is: [tex]\mathbf{(x,y) \to (-x - 1,-y + 6)}[/tex]
And the image of the transformation are:
[tex]\mathbf{D = (3,1)}[/tex] [tex]\mathbf{E = (2,5)}[/tex] [tex]\mathbf{F = (4,4)}[/tex]

Solve 13+b>34. Graph the solution.
I give lots of points
Question:
13 + b > 34
Step 1: Keep variable on one side, and subtract 13 on both sides.
b > 21
Step 2: Now that you have the value of b, create a number line that includes the number "21"
Step 3: Since it is not "or equal too" we will use an open dot, since we do not contain that point. Put dot over 21.
Step 4: The sign is ( > ) meaning greater than. Therefore all points greater than 21 is true. See graph.

Sally's pet grooming business charges $5 per cat and $10 per dog for a pet bath. She earned $550 for pet baths last month. If 20 of those were cats, how many were dogs?
Answer:
45 dogs
Step-by-step explanation:
so she has $550 and she did 20 cats and it costs $5 per cat and 5 x 20 is $100 and $550 - $100 = 450 and 450 divided by 10 ( because it's $10 per dog) is 45.

What polyominal should be subtracted from 3x^2+4x-1 to get the difference equal to x^2
Step-by-step explanation:
(3x² + 4x - 1) - ? = x²
Therefore ? = (3x² + 4x - 1) - x² = 2x² + 4x - 1.
The polynomial that should be subtracted is 2x² + 4x - 1.

Three-fifths of the sum K and 6 plus the product of 8 and x
Answer
3/5=k6+8x
Step-by-step explanation:
Simplifying
2(k + -5) + 3k = k + 6
Reorder the terms:
2(-5 + k) + 3k = k + 6
(-5 * 2 + k * 2) + 3k = k + 6
(-10 + 2k) + 3k = k + 6
Combine like terms: 2k + 3k = 5k
-10 + 5k = k + 6
Reorder the terms:
-10 + 5k = 6 + k
Solving
-10 + 5k = 6 + k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-1k' to each side of the equation.
-10 + 5k + -1k = 6 + k + -1k
Combine like terms: 5k + -1k = 4k
-10 + 4k = 6 + k + -1k
Combine like terms: k + -1k = 0
-10 + 4k = 6 + 0
-10 + 4k = 6
Add '10' to each side of the equation.
-10 + 10 + 4k = 6 + 10
Combine like terms: -10 + 10 = 0
0 + 4k = 6 + 10
4k = 6 + 10
Combine like terms: 6 + 10 = 16
4k = 16
Divide each side by '4'.
k = 4
Simplifying
k = 4
