Answer:

3x + 5y + 10= 3

5x - 3y = -6

Step-by-step explanation:

1. m=-3/5

2. Simplifying

5x + -3y = 6

Solving

5x + -3y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

5x + -3y + 3y = 6 + 3y

Combine like terms: -3y + 3y = 0

5x + 0 = 6 + 3y

5x = 6 + 3y

Divide each side by '5'.

x = 1.2 + 0.6y

Simplifying

x = 1.2 + 0.6y

Answer:

It is 0.23 with the 23 repeating. The decimal repeats when he divided into the same number twice.

Step-by-step explanation:

23÷99=0.232323232

Since 0.232323232 is a repeating decimal with the 23 repeating, it can be represented as 0.23 with the line over 23

Note:

Sorry for the extra words it doesn't allow me to write the vinculum (the line that indicates a number is repeating)

Step-by-step explanation:

Answer:

2 7/15

Step-by-step explanation:

2 2/5 + 1/15

Turn them into improper fractions.

12/5+1/15

In order to add fractions, they need the same denominator.

12/5x3/3=36/15

36/15+1/15=37/15

=2 7/15

Step-by-step explanation:

The rate of the block of glasses is, $18.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Kim pays $90 for every block of 5 dance classes.

Here, Kim pays $90 for every block of 5 dance classes.

Hence, The rate of the block of glasses is,

⇒ $90 / 5

⇒ $18

Answer:

Step-by-step explanation:

A parabolic graph with no real zeros never touches or crosses the x-axis.  

If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.

If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.

Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3.  (Note:  this is strictly an example.)  Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,

y = a(x - h)^2 + k.  Here h = -2 and k = -1, and so the particular parabola is

y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.

In general form, this would be y = -a(x^2 + 4x + 4) - 1, or

                                                   y = -ax^2 - 4ax - 4a -1

and the constant terem (-4a -1) must be an odd negative integer

This is only one of an infinite number of possible equations for the parabola described above.
