Answer:
1.5
- 3/4
Step-by-step explanation:
To find the opposite of a number, you just have to either add or remove a negative sign.
- 1.5 is negative, so the opposite of negative 1.5 is positive 1.5 or 1.5
3/4 is positive, so the opposite of positive 3/4 is negative 3/4 or - 3/4
I Hope That This Helps! :)

*x=1,y=2
*x=2,y=1
*x=-2,y=-1
Answer:
Solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
Step-by-step explanation:
We are given equations:
[tex]y=x-1---eq(1)\\2x-y=0---eq(2)[/tex]
We need to solve by Elimination method.
Elimination method: Add or subtract the equations to get an equation in one variable.
Rearranging the equation 1 we get
[tex]-x+y=-1---eq(1)\\2x-y=0---eq(2)[/tex]
Add eq(1) and eq(2)
[tex]-x+y=-1\\2x-y=0\\------\\x=-1[/tex]
So, after eliminating y we get x=-1
Now finding y by putting x in eq(1)
[tex]y=x-1\\y=-1-1\\y=-2[/tex]
We get y=-2
So, solving this system of linear equations by elimination we get x=-1 and y=-2

7d – 4d – 3d – 5 = 6d
Answer:
[tex]d = -\frac{5}{6}[/tex]
Step-by-step explanation:
7d – 4d – 3d – 5 = 6d
(7d - 4d = 3d)
3d - 3d -5 = 6d
(3d - 3d = 0)
0 - 5 = 6d

original price of CD: $13.00
Discount: 40%
Answer:
$7.80
Step-by-step explanation:
Multiply 0.4 (that is 40%) by 13
It would be 5.2
So subtract 5.2 from $13.00
7.8
So the CD price would be $7.80 with a 40% discount
Hope this helps you :)
Answer:
$5.20
Step-by-step explanation:
First you needed to multiply 0.40 and 13 so that would give you 5.2 so because you are dealing with money you need to add a two after the 2 in 5.2 to make it $5.20. I hope this helped!

Trevor is looking at purchasing a new cellular phone plan. Company A charges $35.25 a month, plus $.11/min for local calls. Company B charges $14.25 a month, plus $.32/min for local calls. Trevor stated that if he used x amount of minutes, the cost of the phone companies would be the same. For what amount of minutes, x, would Trevor's argument be true? Trevor is planning to use at least a 100 minutes for local a month. Which company would be cheaper for Trevor to use?
Answer: Trevor's argument will be true if he used 100 minutes.
Let x represent the amount of minutes that Trevor would use for the cost of the phone companies to be the same.
Company A charges $35.25 a month, plus $.11/min for local calls. This means that the total cost of making x minutes of call with Company A's plan is
32.25 + 0.11x
Company B charges $14.25 a month, plus $.32/min for local calls. This means that the total cost of making x minutes of call with Company B's plan is
14.25 + 0.32x
For both costs to be the same, the number of minutes would be
35.25 + 0.11x = 14.25 + 0.32x
0.32x - 0.11x = 35.25 - 14.25
0.21x = 21
x = 21/0.21 = 100

Select the true statement about triangle ABC.
A. sin C = tan A
B. sin C = cos B
C. sin C = cos A
D. sin C = sin A
Answer:
C
Step-by-step explanation:
sin C=12/13
cos A=12/13
so sin C=cos A
The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is C.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
Let's solve the given statement as shown below.
A.)
sin C = tan A
sin C = 12/13
tan A = 5/12
Therefore, the given equation is not true.
B. sin C = cos B
sin C = 12/13
cos B = 5/13
Therefore, the given equation is not true.
C. sin C = cos A
sin C = 12/13
cos A = 12/13
Therefore, the given equation is true.
D. sin C = sin A
sin C = 12/13
Sin A = 5/13
Therefore, the given equation is not true.

Pam is having a yard sale. For each item, she is asking for two-fifths of the price for which she bought the item. Write an equation for the situation, where y is the price she is asking and x is the original price of the item.
Answer:
The equation is 2x = 5y
Step-by-step explanation:
From the question, we are told that what is asked is 2/5 of the price for which each of the items are bought
y is the asking price, x is the original
Mathematically,
that would be;
y = 2/5 * x
y = 2x/5
Thus;
2x = 5y

Step-by-step explanation:
f(n) = -n^3 – 4
g(n) = -n +4
f(n)+ g(n) = (-n^3 – 4n)+(-n +4)
= (-n^3 – 4n -n +4)

y= -3x-1
Step-by-step explanation:
hope this helps :)
Answer:
y = - 3x - 1
Step-by-step explanation:
The equation in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (2, - 7) ← 2 ordered pairs from the table
m = [tex]\frac{-7+4}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute any ordered pair into the partial equation
Using (1, - 4 ), then
- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1
y = - 3x - 1 ← equation of linear function

What is 7x=5y x 6. Plllllssss heeelllp meh. Im stupid and don't know what this is.
Answer:
x=0
Step-by-step explanation:
"x6" was replaced by "x^6".
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :7x-(5y*x^6)=0
7x - 5x6y = 0
7x - 5x6y = -x • (5x5y - 7)
-x • (5x5y - 7) = 0 Hope this helps and you are not stupid everybody has at least something that they dont understand :)))
