Answer:
3x+20y
Step-by-step explanation:
First write down the expression.
5(x + 5y) - {2x – [3x – 3(x – 2y) + y]}
Now, the first thing you would have to do is the first parenthesis
5(x+5y)
5x+25y
So far, the expression looks like this: 5x+25y - {2x – [3x – 3(x – 2y) + y]}
No we would do the smallest parenthesis in the expression.
Which is: (x – 2y)
But since there is nothing to simplify, we move on
Next one is [3x – 3(x – 2y) + y]
We have to do 3(x-2y) first
This is equal to: 3x-6y
So far, the expression looks like this:5x+25y - {2x – [3x – 3x-6y + y]}
The next step is still in the other parenthesis up top
Which is: [3x – 3x-6y + y]
We have to add up the x's and y's
Which is -5y
Our expression now looks like this:5x+25y - 2x-5y
Since we don't have anymore parenthesis, we look for the same letter and add or subtract them.
We have to do 5x-2x=3x
25y-5y=20y
So that means our final answer is :3x+20y
Hope this answer is correct!

The vertices of the image of GHJK after a translation are given. Choose the vector that describes the translation.
Answer:
Option B
Step-by-step explanation:
Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,
From the graph attached,
Coordinates of G → (-5, 5)
Coordinates of the image point G' after the translation → G'(-5, 5)
Let the point G is translated 'a' units to the right and 'b' units down,
Rule for this translation,
G(x, y) → G'(x + a, y - a)
By this rule,
G(-5, 5) → G'(-5 + a, 5 - a)
-5 + a = -5 ⇒ a = 0
5 - a = 5 ⇒ a = 0
Therefore, vector that defines the translation will be,
<0, 0>
Option B is the the correct option.
The vector that describes the translation of the image is: b. (0, 0).
Recall the rules of translation:
The image attached below shows how an image is translated using a rule.In the image, since we are down to the right, the rule for the translation is given as: [tex](x + x_1, y - y_1)[/tex], where [tex]a[/tex] = units moved to the right, and [tex]b =[/tex] units moved downwards.Thus, from the image given to us showing the image of GHJK, using one of the vertex J' (-3, 3) and the translation rule, [tex](x + a, y - b)[/tex], the vector describing the translation can be determined as follows:
The coordinates of vertex J = (-3, 3)
[tex]x = -3 \\\\ y = 3[/tex]
Substitute[tex]J(-3, 3) = (-3 + a, 3 - b)\\\\-3 = -3 + a\\\\-3 + 3 = a\\\\\mathbf{0 = a} \\\\\\3 = 3 + b\\\\3 - 3 = b\\\\\mathbf{0 = b} \\\\[/tex]
Therefore, the vector that describes the translation of the image is: b. (0, 0).

24 + 8p = – 8(5 + 3p)
Answer:
p= -2
Step-by-step explanation:
24+8p= -40-24p
32p= -64
p= -2
Step-by-step explanation:
24 + 8p = -8(5+ 3p) Original Problem
24 + 8p = -8(5) + -8(3p) Distributive property
24 + 8p = -40 - 24p Simplification
24 + 8p - 24 = -40 - 24p -24 Grouping the constants
8p = -64 - 24p Simplification
8p + 24p = -64 -24p +24p Grouping the variables
32p = -64 Simplification
32p/32 = -64/32 Isolating the variable
p = -2 The Answer!!!!

Over the next 17 months you have to read at least 68 books. You have to read x books per month.
The inequality 17x2 68 represents this situation. Solve the inequality to find the number of books
you have to read per month.
Answer:
You have to read 4 or more books per month.
Step-by-step explanation:
Given that:
Number of months to read the books = 17 months
Number of books to read = 68 at least
Number of books per month = x
The inequality for the situation is;
[tex]17x\geq 68[/tex]
Dividing both sides by 17
[tex]\frac{17x}{17}\geq \frac{68}{17}[/tex]
x ≥ 4
Hence,
You have to read 4 or more books per month.

Complete the missing value in the solution to the equation.
(8,____)
Answer:
The missing value is 5.
Step-by-step explanation:
Since we already have x-value for the equation. What we need to do is to substitute the value of x in the equation.
Substitution
[tex]5x - 2y = 30[/tex]
Then we substitute x = 8 in the equation.
[tex]5(8) - 2y = 30 \\ 40 - 2y = 30 \\ 40 - 30 = 2y \\ 10 = 2y \\ \frac{10}{2} = y \\ 5 = y[/tex]
Answer Check
It is better to check the answer before jumping to the conclusion. We can check if the answer is right by substituting both terms in the equation. If the equation is true then the answer is correct. If the equation is false then one of the term is incorrect.
[tex]5x - 2y = 30[/tex]
Substitute x = 8 and y = 5 in the equation.
[tex]5(8) - 2(5) = 30 \\ 40 - 10 = 30 \\ 30 = 30[/tex]
The equation is true for (8,5)
Therefore, the missing value is 5.

A ball is thrown with an initial speed of 17 mph in a direction that makes an angle of 22 degrees with the positive x-axis. Express the velocity vector v in terms of i and j.
Answer:
The speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Step-by-step explanation:
Given;
velocity of the ball, v = 17 mph
angle of inclination, θ = 22⁰
The horizontal component of the velocity is calculated as;
[tex]V_x = Vcos\theta\\\\V_x = 17cos(22)\\\\V_x = 15.76 \ i[/tex]
The vertical component of the velocity is calculated as;
[tex]V_y = Vsin\theta\\\\V_y = 17sin(22)\\\\V_y = 6.37 \ j[/tex]
Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)

Which sequence of transformations will change figure PQRS to figure P′Q′R′S′?
a. Counterclockwise rotation about the origin by 90 degrees followed by reflection about the x-axis
b. Counterclockwise rotation about the origin by 180 degrees followed by reflection about the x-axis
c. Counterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axis
d. Counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis
Answer:
d. Counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis
Step-by-step explanation:
Solid transformation is a process which changes the orientation, shape and size of a given objects. Types of solid transformation are: rotation, reflection, dilation etc. This process would produce an image of the initial figure which has been transformed appropriately.
From the given question, figure PQRS can be transformed into P′Q′R′S′ by a counterclockwise rotation at [tex]90^{o}[/tex] about the origin. This would be followed by a reflection about the y-axis.
Thus, the correct option is D.
