anyone know how I can solve this ? x = -2y - 1 ​

Answer:

Yes

Step-by-step explanation:

You would first need to make the fraction a decimal which would be 0.5

Answer:

63 I think

you can find a common denominator by multiplying the denominators together. however keep in mind that what you do to the bottom you must do to the top

1/7 would become 9/63 and 2/9 would become 14/63

Answer:

- 978.6 gallons per hour

Step-by-step explanation:

Given that :

Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal

Time during which change occurred : 2:00 pm to 4:00 pm

Average change per hour : [Change in gallon of gasoline / time interval (hour)]

Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons

Time interval = 4:00 pm - 2:00 pm = 2 hours

Hence, Average change per hour :

-1957.2 / 2

= - 978.6 gallons per hour

Answer:

x = [tex]21^{o}[/tex]

Step-by-step explanation:

The opposite sides of the parallelograms are equal and parallel to each other. Thus, from the alternate angle principle (alternate angles are said to be equal), then;

2x = 42  (alternate angle principle)

x = [tex]\frac{42}{2}[/tex]

 = [tex]21^{o}[/tex]

x = [tex]21^{o}[/tex]

Therefore the value of x in the question is [tex]21^{o}[/tex].

Answer:

36

Step-by-step explanation:

3/4y=6-1/3c

3/4y+1/3c=6

multiplied 6 into equation to get 2c

9/2y+2c=36

so 2c+9/2y=36

The value of 2c + (9/2)y is 36.

Given,

(3/4)y = 6 - (1/3)c

We need to find the value of 2c + (9/2)y.

It depends on the type of expression.

We need to see what is required to find in the expression.

If we need to find 2x in an equation of x + 7 = 3 + y

x + 7 = 3 + y

We will multiply 2 in the equation.

2( x + 7 ) = 2 ( 3 + y )

2x + 14 = 6 + 2y

2x = 6 + 2y - 14 is our answer.

Find 2c + (9/2)y

We have,

(3/4)y = 6 - (1/3)c

We need to write it as:

(3/4)y + (1/3)c = 6 _______(1)

We need to make (1/3)c into 2c and (3/4)y into (9/2)y.

Multiply 6 on both sides on (1).

6 x [ (3/4)y + (1/3)c ] = 6 x 6

6 x (3/4)y + 6 x (1/3)c = 36

[ (3 x 3) / 2] y + (6/3) c = 36

(9/2)y + 2c = 36

2c + (9/2)y = 36

Thus the value of 2c + (9/2)y is 36.

Step-by-step explanation:

Take the common factor 4 out.

[tex]4([/tex]

Then divide the numbers inside the expression with the common factor

[tex]4( \frac{ - 4x}{4} + \frac{12}{4})[/tex]

[tex]4( - x + 3)[/tex]

You can rewrite it as:

Answer: 4(-x+3)

Step-by-step explanation:

Hii, do you need to factor the expression -4x+12? No problem! (:

Note that both -4x and 12 have something in common. This "something" is known as the greatest common factor, or g.c.f.

The g.c.f. of -4x+12 is 4.

To factor it out, we first need to divide -4x+12 by 4.

-x+3 is what we obtain

Next, we put parentheses around -x+3

(-x+3) is what we obtain

Finally, we put 4 outside the parentheses

4(-x+3)

Answer:

The first one

Step-by-step explanation:

The function f(x) = {x + 3,  x < 0,    3      x ≥ 0} represents the graph.

In mathematics, the set of ordered pairings where f(x)=y exists is the graph of a function f. These pairs are Cartesian coordinates of points in two-dimensional space and so form a subset of this plane in the typical situation when x and f(x) are real integers.

here, we have,

given that,

As show in the graph we can see that the function has a graph of x + 3 on left side of the y - axis for x < 0.

And the function has the constant graph y = 3 for x ≥ 0.

Therefore, the given graph is the graph of the function,

f(x) = {x + 3,  x < 0,    3      x ≥ 0}.
