How many solutions does the system 2y=10x-14 and 5x-y=7 have ?

I find it of tremendous use to convert to the slope intercept form to easily visualize the lines.  The first is:
y = 5x - 7  [Dividing both sides by 2] and the second is:
-y = -5x + 7  [Subtracting 5x from each side]
y = 5x - 7 [Dividing each side by -1]

These two equations represent the same line.  If the lines were parallel, there would be no solution.  If the lines intersected, there would be only one unique solution satisfying both equations (the point of intersection).

In this case, where the two equations represent the same line, the number of solutions is infinite.

The answer is:  <span>∞

Step-by-step explanation:

Perimeter = x + 2x + 2x = 5x

Since 5x <= 46.8cm, x <= 9.36cm.

The largest base is 9.36cm.

jeyben [28]

Answer:

A

Step-by-step explanation:

To evaluate f(2), substitute x = 2 into f(x), that is

f(2) = 2(2)² - 5(2) = 2(4) - 10 = 8 - 10 = - 2 → A

Maria compared the slope of the function f(x)=(-6x-21) to the slope of the linear function that fits the values in the table bel
raketka [301]

Answer:

b. both functions have a negative slope

Step-by-step explanation:

The given function is

f(x)=-6x-21


This function is of the form y=mx+b, where m=-6 is the slope and b=-21 is the y-intercept.


We can also determine the slope of the function in the table using any two points, say (0,7)\:and\:(2,6).


The slope formula is given by,

m=\frac{y_2-y_1}{x_2-x_1}.


If (x_1,y_1)=(0,7)\:and\:(x_2,y_2)=(2,6), then,

m=\frac{6-7}{2-0}


m=-\frac{1}{2}.


We can see that both functions have a negative slope.


The correct answer is B.

Answer:

2 y = 100

10 y = 20

20 y = 10

Step-by-step explanation:

To find the answer divide Y by X since y is 200 in the first and x is 1 divide 200 by the second one and you will find you answer.
