Answer:
positive (+)
Step-by-step explanation:
- × - = +
+ × - = -
+ × + = +
Answer:
there are 8 numbers, all are negetive and they are multiplied with each-other
we know, (-negative)(-nagative) = positive number
so even quantity of negative numbers multiplied with each-other makes a positive number.
so the sign of the product is +

Solve the equation below for y in terms of x.
(Slope Intercept Form, y = mx + b)
2y - 3x = 7
Point A is (2, -3) Use each transformation rule to find the coordinates of A’. Final answer in ( )
(x,y) ---->(x +3, y-1) A’=_________________________
(x,y) ----> (x, y-4) A’ = ________________________
By transformation rules, the points A₁(x, y) = (5, - 4) and A₂(x, y) = (2, - 7) are images of point A(x, y) = (2, - 3)
How to obtain the image of a point by a vector
In this problem we must determine two images associated to a given point and that are result of an transformation rule known as a translation. This transformation rule is described below:
A'(x, y) = A(x, y) + T(x, y)
Where:
A(x, y) - Original point.A'(x, y) - Image of the point.T(x, y) - Translation vector.First, write the coordinates of the original point:
A(x, y) = (2, - 3)
Second, find the images of the original point by transformation rule:
A₁(x, y) = (2, - 3) + (3, - 1)
A₁(x, y) = (5, - 4)
A₂(x, y) = (2, - 3) + (0, - 4)
A₂(x, y) = (2, - 7)

What is the solution to the inequality 13 x + 3 < 42 ?
Answer:
x < -15
Step-by-step explanation:
Here is the solution:
-3x-42 > 3
Add the numbers
-3x > 45
Divide both sides of the inequation by -3 and flip the inequality sign.
x < -15

When solving an equation using desmos, how many solutions do you have when a single vertical line crosses the x-axis?
Only 1 solution because you pass through the x-axis only once. Here is an example image below.
what the slope of a line
Answer:
The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.

reflect triangle abc over the line x= -1 and then translate (x+2,y-5) determine the coordinates of B'
Answer:
below
Step-by-step explanation:
You didn't show the triangle, but we suppose the coordinate of B is (x,y)
when it reflect over the line x=-1, (x , y) - > (- (x - (-1)) , y) ==> (- (x+1) , y)
then translate (x+2,y-5) : (-(x+1) , y) -> - (-(x+1)+2 , y-5) ==> (-x+1 , y-5)
such as (5,3) -> (-6,3) -> (-4 , -2)
Solve for x given the point (x,9) is a point on the line y = 3x + 7.
Answer:
0.67 = x
Step-by-step explanation:
to solve the value of x we need to : (x,9)
y = 3x + 7
9 = 3x + 7
9 - 7 = 3x
2 = 3x
2/3 = x
0.67 = x
From the given point (x , 9) let's plug the value of its y - coordinate of into Equation - y = 3x + 7 and solve for x :
[tex]9 = 3x + 7[/tex][tex]2 = 3x[/tex][tex]x = \dfrac{2}{3} [/tex]hence, value of x = 2/3
Carmen wants to buy a pair of shoes that regularly costs $78. Today, the shoes are on sale for 60% of the original price. How much will Carmen have to pay for the shoes?
Answer:
31.2
Step-by-step explanation:
Change 60% into 0.6 by moving the decimal 2 points to the left
Multiply 0.6 by 78 to get 46.8

15
The fraction 15 is the same as 15 divided by ___
Answer:
If its just 15 then its 1
Step-by-step explanation:
Because 15 divided by 1 is 15 which is the fraction.
Answer:
Below,...!
Step-by-step explanation:
15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:
[tex]\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}[/tex]
15/1 is your fraction so 15/1 divided into 15 equals 1
[tex]\frac{15}{1} / 15 = 1/1 = 1[/tex]

What is thissss someone help
Answer:
1. Neither
2. Odd
3. Odd
4. Even
Step-by-step explanation:
Graphically, an equation is even if it is symmetrical across the y-axis. An equation is odd if it is symmetrical after folded over y and x. An equation is neither if it fulfills neither requirement.
Algebraically, an equation is even is f(x) = f(-x), and an equation is odd if f(-x) = -f(x).
Hope it helps :) and let me know if you want me to elaborate.

solve the following eqation: -8.2 + t/-2 = 1.7
Answer:
t = -19.8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-8.2 + \frac{t}{-2} = 1.7[/tex] [tex]-8.2 - \frac{1}{2}t = 1.7[/tex] [tex]-\frac{1}{2}t - 8.2 = 1.7[/tex]Step 2: Add 8.2 to both sides.
[tex]-\frac{1}{2}t - 8.2 + 8.2 = 1.7 + 8.2[/tex] [tex]-\frac{1}{2}t = 9.9[/tex]Step 3: Multiply both sides by -2.
[tex]-\frac{1}{2}t * (-2)= 9.9 * (-2)[/tex] [tex]t = -19.8[/tex]Х у
