What is the solution to 15 - 4y = -21 - y

Maurinko [17]

Answer:

y = 12

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15 - 4y = - 21 - y

15 + - 4y = - 21 + - y

- 4y + 15 = - y - 21

Step 2: Add y to both sides.

- 4y + 15 + y = - y - 21 + y

- 3y + 15 = - 21

Step 3: Subtract 15 from both sides.

- 3y + 15 - 15 = - 21 - 15

- 3y = - 36

Step 4: Divide both sides by - 3.

- 3y/- 3 = -36/- 3

y = 12

I am so sorry if it is long and confusing, but, I hope this still helps!

What is the equation for the line with a slope of - 2/3 that passes through (0, -2)

viktelen [127]

Answer:

y= -2/3x-2

Step-by-step explanation:

Since we have a point and a slope, we can use the point slope formula

$y-y_{1} =m(x-x_{1})$

m is the slope. In this case, m is -2/3

y1 is the y coordinate of the point. In this case, it is -2

x1 is the x coordinate. In this case it is 0.

We can substitute these values into the formula

y- -2= -2/3(x-0)

Distribute -2/3

y+2 = -2/3*x + -2/3*0

y+2= -2/3x+0

Subtract 2 from both sides. We want to get y by itself. This is because we want our line to be in y=mx+b form.

y+2-2= -2/3x+0-2

y= -2/3x -2

Let

x-----> the number of oranges

y-----> the number of apples

we know that

The inequality that represent this situation is

$0.45x+0.25y\leq 2$

The solution is the shaded area below the solid line between the positive whole numbers values of x and y

Diana is a piano teacher who charges $45 per hour plus an additional flat fee of $20 for travel. The equation that represents th

nikklg [1K]

To shift vertically the graph of the function $f(x)$ , you have to add a constant to its expression:

$f(x) \to f(x)+k$

If k is positive, you shift the function k units above, if k in negative, you shift the function k units below.

So, if you want to shift the graph of $f(x)=45x+20$ two units down, you have to subtract 2 (i.e., add -2):

$f(x) = 45x+20 \to 45x+20-2 = 45x+18$
