Multiply and verify the result when x=1,y=2
(Xy+xy^2 -1) (2x+3y)

Answers

Answer 1
Sub in the values of X and Y
(1 * 2 + 1 * 2^2 - 1) (2 * 1 + 3 * 2)
PEMDAS. Everything is in parentheses so on to exponents. We have one. 2^2 = 4 so,
(1 * 2 + 1 * 4 - 1) (2 * 1 + 3 * 2)
Next, multiplication and division left to right.
(2 + 4 - 1) (2 + 6)
Addition and subtraction left to right.
(5) (8) or 5 * 8
Start PEMDAS over with the rest now that we’re outside of the original parentheses. No parentheses to navigate, no exponents left, multiplication and division. 5 * 8 = 40

Answer: 40

Find the equation of this line.
y = x + [ ]

Answers

Its y=x + 2 the line doesnt in 1

The Equation of line is y = -x + 3.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Take the points (4, -1) and (0, 3).

so, the slope of line is

m = (3+ 1)/ (0-4)

m = 4/ (-4)

m = -1

So, the equation of line

y= mx+ b

y= -x + b

and, 3 = b

So, the required equation is y = -x + 3.

y - y_1 = m(x - x_1)   when : x_1= 1   y_1= 4

     m is the slope  m=(y_1 - y_2)/( x_1 -  x_2)  and  x_2=6   y_2= -1

m = (4+1)/(1-6)= 5/-5 = -1

While performing a vertical line test on a graph, you notice that the graph intercepts the vertical line twice. Which of the following correctly interprets the result of the test? (1 point) Because the vertical line intercepted the graph exactly twice, the graph is of a function. Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function. Because the vertical line did intercept the graph exactly twice, the graph is a function and a relation. Because the vertical line intercepted the graph more than once, the graph is of a function, but it is not a relation.

Answers

Answer:

The correct option is;

Because the vertical line intercept the the graph more than once, the graph is of a relation but it is not a function

Step-by-step explanation:

A function is a kind of relation that maps a given set of inputs unto a set of outputs such that each of the values of the input can be linked to only one value of the output, such that the input and outputs form a set of ordered pairs

Therefore, a relation which maps a given input to more than one output is not a function, as such, given that the line intercepts the vertical line twice, then for a given value of x, which is the input, there are more than one value of y, which is the output, as such the relation is not a function.

Which equation represents each dimension of the larger triangle, y, based on the corresponding dimension of the smaller triangle, x?

Y= 2/3x
Y= 3x
Y= 1/3x
Y= 3/2x

How can you use the given side lengths of the triangles to check if your equation is correct?

Answers

Answer:

  (b)  y = 3x; check using dimensions from the figure

Step-by-step explanation:

The dimensions in the larger triangle are more than the dimensions in the smaller triangle. That means the smaller dimensions need to be multiplied by a value greater than 1 to get the larger dimension. (This eliminates the 1st and 3rd choices.)

__

Equation

The figures are drawn approximately to scale, so it is easy to see that the larger triangle's dimensions are more than double (2 times) those of the smaller triangle. (This eliminates the 4th choice. 3/2 < 2)

The equation that represents the larger dimensions in terms of the smaller ones is ...

  y = 3x

__

Check

You can check this by choosing a smaller dimension and using that in the equation:

  bottom leg = 3 in

  larger bottom leg = y = 3(3 in) = 9 in . . . . matches the diagram
