12x-18y=9. Solve for y

It's the same as #1 you just have to simplify x and y for w.

x + 2 = 0 | -2

x = -2

y + 3 = 0 | -3

y = -3

All realvalues of x where 1 < x < 4.

What is the Graph function?

The graph of a function f is the set of all points inside the aircraft of the shape (x, f(x)). We can also define the graph of f to be the graph of the equation y = f(x). So, the graph of a character is a unique case of the graph of an equation.

How does Graph function?

For graphing functions, we need to plot its asymptotes, its x and y-intercepts, holes, and some factors on it by means of building a desk of values. Then simply join the factor by not touching the asymptotes and maintaining a observation of the area and range of the characteristic.

Answer:

C

Step-by-step explanation:

all real values of x where 1 < x < 4

If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.

4 hours at 60 miles per hour = 4*60 = 240 miles

6 hours at 65 miles per hour = 6*65 = 390 miles

This is a total of 630 miles.  There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

Hi there!

To solve your answer, since we know a = 7, we can easily solve your equation.

But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.

When you have a number, and a variable attached to it, it means to multiply.

Now, to make this equation look a little easier, lets rewrite it.

9 × 7 - 5 × 7 = ___

According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.

9 × 7 = 63.

5 × 7 = 35.

Now, since we've multiplied the two numbers, its time to subtract them.

63 - 35 = 28. Sooooo........

9 × 7 - 5 × 7 = 28

Hope this helps!

Message me if you need anything else, I'd be happy to help you out! :D
