QUESTION POSTED AT 19/08/2019 - 05:51 PM

Rearrange the equation to the form:

y = mx + b

where b is the y-intercept.

-3x - 9y = 18

-9y = 3x + 18

y = -(x/3) - 2.

The answer is b. -2.

y = mx + b

where b is the y-intercept.

-3x - 9y = 18

-9y = 3x + 18

y = -(x/3) - 2.

The answer is b. -2.

Y = kx

We have to find k value, so lets say x is euros and y is American dollars

so we have

9 = k(8)

k = 1.125

so the equation will be y = 1.125x

to prove it use another value given

y = 1.125x

y = 1.125 (24)

y = 27

Thus 24 euros is 27 dollars.

Hence the equation y =1.125x is correct.

You can find slope by using slope formula which is

m = (y2-y1)/(x2-x1)

To find y intercept form, use given point and slope and put it in this form,

y = mx+c

m = (y2-y1)/(x2-x1)

To find y intercept form, use given point and slope and put it in this form,

y = mx+c

There will always be a point symmetrical to the given point on the other side of the parabola.

To find that other point, know that the perpendicular distance to the line of symmetry is the same for both points.

The perpendicular (shortest) distance from (-5,6) to the line x = -2 will be to the point (-2,6) on that line.

The perpendicular (shortest) distance from (-5,6) to the line (-2,6) is the change in x coordinates, or absolute value difference in x coordinates. |-5--2| = 3.

Then go 3 units to the right of (-2,6) to find the other point because the other symmetrical point also is the same distance to the middle point (-2,6). The answer is (1,6)

A polynomial function is a relation between one variable to another variable with some restrictions to limit its behavior. In simpler terms, a polynomial function is simply a subset of functions altogether. Polynomial functions are special in that they contain zero discontinuities in their behavior, have distinct features have end behaviors that approach infinity. These functions are excellent for demonstrating real life situations, such as banking trends.

**Answer:**

3 x + 10 y = 50

This is the equation which can be used to find the number of each type of weight Bob has.

**Step-by-step explanation:**

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs.

Let x represents the number of 3 lb weights and y represents the number of 10 lb weights

Total weight = 50 lb

Number of 3 lb weights = x

Number of 10 lb weights = y

Equating

3 x + 10 y = 50

This is the equation which can be used to find the number of each type of weight Bob has.
