Doing an Algebra assignment that is due today, I have multiple problems I need help with, I'm posting 5 questions at a time since I can't post them all.

Answer:
1) 8x^2-10x-7
2) 30[tex]x^{9\\}[/tex]- 60[tex]x^{5}[/tex]
3) -10y^6 - 45y^5 + 25y^4
4) 30x^9 - 60x^5
5) 30x^9 - 60x^5
Step-by-step explanation:
1) (2x+1)(4x-7), we will multiply each term from the first parenthesis against every term in the second.
2x*4x = 8[tex]x^{2}[/tex], 2x*-7 = -14x
1(4x-7) = 4x-7.
8x^2-14x+4x-7 = 8x^2-10x-7
2) 10[tex]x^{5}[/tex](3x^4-6)
10x^5(3x^4) = 30x^9
10x^5(-6) = -60x^5
30[tex]x^{9\\}[/tex]-60[tex]x^{5}[/tex]
3) -5y^4(2y^2+9y-5)
-5y^4(2y^2) = -10y^6
-5y^4(9y) = -45y^5
-5y^4(-5) = 25y^4
-10y^6 - 45y^5 + 25y^4
4) 10x^5(3x^4 - 6)
10x^5(3x^4) = 30x^9
10x^5(-6) = -60x^5
30x^9 - 60x^5
5) (3y - 5z)(8y - 3z) =
3y*8y = 24y^2
3y*(-3z) = -9yz
-5z(8y) = -40yz
-5z(-3z) = 15z^2
24y^2 + 15z^2 - 49yz

What is the image of A(1,-3)?
use the following transformations with each question:
Reflection across the x-axis
Reflection across the y-axis
Reflection across the y = x
Reflection across the y = -x
Answers
Step-by-step explanation:
Given A(1 , -3)
Reflection across the x -axis
= A'( 1 , 3)
Reflection across the y-axis
= A'( -1 , - 3)
Reflection across the y = x
= A' ( -3 , 1)
Reflection across the y = - x
=A'( 3 , - 1)

The answer to the question provided is:
[tex] \frac{7}{4} [/tex]
Step-by-step explanation:
❃This what the slope formula looks like:
[tex]slope = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
❃All we have to do is plug in:
[tex]slope = \frac{4 - ( - 3)}{6 - 2} = \frac{7}{4} [/tex]
❃Therefore, the slope is:

(6 - 1) + (3m)i = -12 + 27i
Answers
Answer:
We want to solve the equation:
(6 - 1) + (3m)i = -12 + 27i
Where m is a complex number.
first, we can rewrite this as:
5 + 3*m*i = -12 + 27*i
3*m*i = -12 - 5 + 27*i
3*m*i = -17 + 27*i
And we can write m as:
m = a + b*i
Replacing that in the above equation we get:
3*(a + b*i)*i = -17 + 27*i
3*a*i + 3*b*i^2 = -17 + 27*i
and we know that i^2 = -1
3*a*i - 3*b = -17 + 27*i
The real part in the left (-3*b) must be equal to the real part in the right (-17)
then:
-3*b = -17
b = -17/-3 = 17/3
And the imaginary part in the left (3*a) must be equal to the imaginary part in the right (27)
then:
3*a = 27
a = 27/3.
Then the value of m is:
m = a + b*i = (27/3) + (17/3)*i

5x=18*5-12
x=(18*5-12)/5

Which of the following is the slope intercept form of the equation
3x - 8y = 16
A- y = 3/8x + 2
B- y = 3/8x - 2
C- y = -3/8x + 2
D- y = -3/8x - 2
Answers
Answer:
y = 3/8 x - 2
Step-by-step explanation:
Put 8y on the other side to get
8y + 16 = 3x
8y = 3x - 16 and thus
y = 3/8 x - 2

what is 3x2 + 5x - x2 - 2x + 3 simplifyed completely
Answers
Answer:
2x^2+3x+3
Step-by-step explanation:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
STEP 1
The Equation at the end of step 1
(3x2 + 5x) - x2) - 2x) + 3
STEP 2
Trying to factor by splitting the middle term
2.1 Factoring 2x2+3x+3
The first term is, 2x2 its coefficient is 2.
The middle term is, +3x its coefficient is 3.
The last term, "the constant", is +3
Step-1: Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2: Find two factors of 6 whose sum equals the coefficient of the middle term, which is 3.
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7
2 + 3 = 5
3 + 2 = 5
6 + 1 = 7
Observation: No two such factors can be found !!
Conclusion: Trinomial can not be factored
Final result :
2x^2 + 3x + 3

Answers
Answer:
y= -7
Step-by-step explanation:
So first distribute the 8
4=8y+32-4y
now combine like terms (the -4y+8y)
4=32+4y
Subtract 32 on both sides to isolate 4y
-28=4y
now divide 4 on both sides to isolate Y
-7=y
so y= -7

The ordered pair that corresponds to point P is: (4, 2)
Step-by-step explanation:
It is clear from the graph that the point P is located at the location (4, 2).
In other words,
at x = 4, y = 2
It means:
The x-coordinate of the point P is: x = 4
The y-coordinate of the point P is: y = 2
Thus, the location of the point P → P(x, y) = P(4, 2)
Please check the attached graph.
Therefore, we conclude that:
The ordered pair that corresponds to point P is: (4, 2)
