What’s the slope of 4x+5y= -20

Mathematics

Morgarella [4.7K]3 years ago

Answer: y = -4/5x-4

Step-by-step explanation:

You start with 4x+5y=-20

Isolate y by moving 4x to the other side, now your problem should look like:

5y=-4x-20

To get y by itself, divide both sides by 5, (don't forget to divide -20 by 5 too)

y=-4/5x-4

Answer:

-4/5

Step-by-step explanation:

Lets put the equation in slope intercept form

4x+5y = -20

Subtract 4x from each side

4x-4x+5y = -4x-20

5y = -4x-20

Divide each side by 5

5y/5 = -4x/5 -20/5

y = -4/5 x -4

The equation is in the form y = mx+b  where m is the slope and b is the y intercept

the slope is -4/5  and the y intercept is -4

Answer:

If the two fractions simplify to fractions with a common denominator, you can then compare numerators. If the denominators are different, you can find a common denominator first and then compare the numerators. Two fractions are equivalent fractions when they represent the same part of a whole.

How many solutions are there for 4x>8
Anni [7]

Answer:

\Huge \boxed{X>2}

Step-by-step explanation:

\large \textnormal{To solve this problem, first you have to isolate it on one side of the equation.}

First, divide by 4 from both sides.

\displaystyle \frac{4x}{4}=\frac{8}{4}

Solve.

\displaystyle 8\div4=\boxed{2}

Therefore, the solutions of 4x>8 is 2.

In conclusion, the correct answer is x=2.

12x + 150 = 0

-150         -150

 12x  =   -150

12x ÷ 12  = -150 ÷ 12

Quadrilateral QRST is a square. If the measure of angle RQT is 3x - 6. Find the value of x.
trapecia [35]

Given that quadrilateral QRST is a square.

Each angle of a square is of 90 degrees.

Angle <RQT is also an angle of 90 degrees.

We also given angle RQT = 3x - 6.

So, we can setup an equation as 3x-6 =90.

Now, we need to solve the equation for x.

6 is being subtracted from left side.

We always apply reverse operation. Reverse operation of subtraction is addition.

So, adding 6 on both sides of the equation, we get

3x-6+6 =90+6.

3x = 96.

3 is being multipied with x, in order to remove that 3, we need to apply reverse operation of multiplication.

So, dividing both sides by 3.

\frac{3x}{3} = \frac{96}{3}

x=32 (final answer).
