3x + 5y + 10
5x - 3y = -6
Answers
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

Step-by-step explanation:
The rate of the block of glasses is, $18.
What is Division method?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.

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!
Answers
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.
