my and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 8 to the number and multiplied the sum by 3, it would equal 9. Which equation could Stephanie use to find the number, x?
A.
3 + (x + 8) = 9
B.
8(x + 3) = 9
C.
3(x + 8) = 9
D.
3(x) + 8 = 9
Answers
3(x+8)=9
Always make sure u do PEMDAS so since the number that Amy picked is unknown we will label it X. Next step was x added to 8 which will look like this x+8 but wants the sum multiplied by 3 so since we don't know the answer we will close it in parenthesis and multiply it by 3 which will look like 3(x+8) and lastly add the equal sign and the number 9.

perpendicular to the line 4x - 6y + 7 = 0 , passing through (3, 4) .
Answers
Answer:
The equation of line perpendicular to given line passing through (3,4) is:
[tex]y = -\frac{3}{2}x+\frac{17}{2}[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]4x - 6y + 7 = 0[/tex]
Given equation is in standard form. It has to be converted into slope-intercept form to extract slope from the equation.
So,
[tex]4x+7 = 6y\\6y=4x+7\\\frac{6y}{6} = \frac{4x+7}{6}\\y = \frac{4}{6}x+\frac{7}{6}\\y=\frac{2}{3}x+\frac{7}{6}[/tex]
The standard form of slope-intercept form of equation is:
[tex]y=mx+b[/tex]
Here, the co-efficient of x is the slope of the line.
So the slope of given line is: 2/3
m = 2/3
The product of slopes of two perpendicular lines is -1
Let m1 be the slope of line perpendicular to given line
Then
[tex]m.m_1 = -1\\\frac{2}{3} . m_1 = -1\\m_1 = -1*\frac{3}{2}\\m_1 = -\frac{3}{2}[/tex]
The equation of perpendicular will be:
[tex]y = m_1x+b[/tex]
Putting the value of slope
[tex]y = -\frac{3}{2}x+b[/tex]
To find the value of b, putting (3,4) in the equation
[tex]4 = -\frac{3}{2}(3)+b\\4 = -\frac{9}{2}+b\\b = 4+\frac{9}{2}\\b= \frac{8+9}{2}\\b=\frac{17}{2}[/tex]
So the equation of line perpendicular to given line passing through (3,4) is:
[tex]y = -\frac{3}{2}x+\frac{17}{2}[/tex]

Answers
Answer:
The answer to the expression in simplest form is:
[tex]\frac{\frac{1}{3}}{\frac{1}{4}}=\frac{4}{3}[/tex]
Step-by-step explanation:
Given the function
[tex]\frac{\frac{1}{3}}{\frac{1}{4}}[/tex]
solving to get the simplest form
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
[tex]\frac{\frac{1}{3}}{\frac{1}{4}}=\frac{1\cdot \:4}{3\cdot \:1}[/tex]
[tex]\mathrm{Apply\:rule}\:a\cdot 1=a[/tex]
[tex]=\frac{4}{3}[/tex]
Thus, the answer to the expression in simplest form is:
[tex]\frac{\frac{1}{3}}{\frac{1}{4}}=\frac{4}{3}[/tex]

Answers
The expressions which are equivalent to the complex number 45 + 2i is E. (9 + 4i) + (36 - 2i)
D. (2 + 8i) + (30 - 6i)
To determine which expressions are equivalent to the complex number 45 + 2i, we can simplify each expression and check if it matches the given number.
Let's evaluate each option:
A. (2 + 8i) + 2(9 + 6i)(1 - i) = 2 + 8i + 2(9 + 6i - 9i - 6i^2) = 2 + 8i + 2(9 + 6i - 9i + 6) = 2 + 8i + 2(15 - 3i) = 2 + 8i + 30 - 6i = 32 + 2i
B. (9 + 4i) + 2(4 + 7i)(1 - 2i) = 9 + 4i + 2(4 + 7i - 8i - 14i^2) = 9 + 4i + 2(4 + 7i - 8i + 14) = 9 + 4i + 2(23 - i) = 9 + 4i + 46 - 2i = 55 + 2i
C. (13 + 4i) + 2(7 + 2i)(2 - i) = 13 + 4i + 2(7 + 2i - 14i - 4i^2) = 13 + 4i + 2(7 + 2i - 14i + 4) = 13 + 4i + 2(24 - 12i) = 13 + 4i + 48 - 24i = 61 - 20i
D. (2 + 8i) + (30 - 6i) = 2 + 8i + 30 - 6i = 32 + 2i
E. (9 + 4i) + (36 - 2i) = 9 + 4i + 36 - 2i = 45 + 2i
F. (13 + 4i) + (32 - 6i) = 13 + 4i + 32 - 6i = 45 - 2i
From the evaluations above, we can see that options E and D are equivalent to the given complex number 45 + 2i.
The correct options are:
E. (9 + 4i) + (36 - 2i)
D. (2 + 8i) + (30 - 6i)

The expressions that are equivalent to the given complex number 45 + 2i are: (9 + 4i) + (36 - 2i) and (2 + 8i) + (30 - 6i).
Thus, option (D) and (E) are correct.
Given complex number 45 + 2i.
A. (2 + 8i) + 2(9 + 6i)(1 - i)
Simplifying: (2 + 8i) + 2(9 + 6i - 9i - 6)
= (2 + 8i) + 2(3 + 3i)
= 2 + 8i + 6 + 6i
= 8 + 14i
B. (9 + 4i) + 2(4 + 7i)(1 - 2i)
Simplifying: (9 + 4i) + 2(4 + 7i - 8i - 14)
= (9 + 4i) + 2(-10 - i)
= 9 + 4i - 20 - 2i
= -11 + 2i
C. (13 + 4i) + 2(7 + 2i)(2 - i)
Simplifying: (13 + 4i) + 2(14 + 4i - 7i - 2)
= (13 + 4i) + 2(12 - 3i)
= 13 + 4i + 24 - 6i
= 37 - 2i
D. (2 + 8i) + (30 - 6i)
Simplifying: 2 + 8i + 30 - 6i
= 32 + 2i
E. (9 + 4i) + (36 - 2i)
Simplifying: 9 + 4i + 36 - 2i
= 45 + 2i
F. (13 + 4i) + (32 - 6i)
Simplifying: 13 + 4i + 32 - 6i
= 45 - 2i
Thus, option (D) and (E) are correct.

Find the equation of the line that is perpendicular to Y= -2/3x and contains the point (4,-8)
Answers
Answer:
Y=-3/5x
Step-by-step explanation:
Answer:
y = 3/2x -14
Step-by-step explanation:
y = -2/3 x
has a slope of -2/3
We want a line perpendicular
Take the negative reciprocal to find the slope
- (1 / -2/3)
3/2
The slope of a line perpendicular is 3/2
Using the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = 3/2x +b
Substitute a point into the equation
-8 = 3/2(4) +b
-8= 6+b
Subtract 6 from each side
-8-6 = b
y = 3/2x -14

A backpack is on sale for 30% off. If the sale price is $15.75, what is the original price to the nearest cent?
Answers
Answer:
$22.50
Step-by-step explanation:
As it is 30% off, $15.75 is 70% of the full price. You can then divide 15.75 by 70 [= 0.225] to get 1% of the full price. Multiply 0.225 by 100 to get the full price. 0.225 x 100 = 22.5
We can check that this answer is correct by multiplying 22.50 by 0.7. If you get 15.75 you know the answer is correct as 15.75 is 70% of the full price.

as you can see, you move 2 more units up on the y-axis with k =3/2. Therefore, it is steeper.
