Select all equations that can result from adding these
two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
(Select all that apply)

Answers

Answer:

Step-by-step explanation:

x + y = 12 ---------------(1)

3x - 5y = 4 --------------(2)

(1)*5 + (2) * 1 then,

5x + 3x = 60 + 4

8x = 64

x = 64/8

x = 8

from (1), 8 + y = 12

y = 4

apply(x,y)=(8,4) to these function.

-2x-4y = -32 no

-2x+6y=8 yes

like this

The required expression after the addition of the equations is  4x  - 4y = 16, and the expression after the subtracting of the equations is -2x +6y =  8.

Given that,
To select all equations that can result from adding these two equations or subtracting one from the other.

equation 1: x + y = 12
equation 2: 3x - 5y = 4

What is the equation?

The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.

Here,
Addition
  x  +   y  = 12
+ 3x - 5y =  4
--------------------
 4x  - 4y  = 16

Subtraction,
  x  +  y  = 12
- (3x - 5y =  4)
--------------------
  x  +  y  = 12
- 3x + 5y = -4
---------------------
-2x + 6y = 8

Thus, the required expression after the addition of the equations is  4x  - 4y = 16, and the expression after the subtracting of the equations is -2x +6y =  8.

Answers

Answer:

The very last set

{(0, 2), (1, 4), (2, 6), (3, 6)}.

The reason why is because of the vertical line test. If there are two y-coordinates on a x-coordinate then it is not a function. A function is that each x-coordinate has a y-coordinate with the x-coordinates being different.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is the exponential function as -

f(x) = (0.5)ˣ + 4

An exponential function is of the form → f(x) = eˣ.

The given function is -

I will write the steps to find the slope and y-intercept from a graph.

Answers

Y-INTERCEPT: It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

SLOPE:The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

The Y intercept is where the line crosses the Y axis on a graph. On an equation in the form Y=Mx+B it would be the +B. On an equation the slope is always the Mx
