19/36 - ⅜ =???????????????????????????

Answers

Answer:

1936−3/8=11/72

Step-by-step explanation:

19/36−38=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(19/36, 3/8) = 72

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(19/36×22)−(38×99)=?

Complete the multiplication and the equation becomes

38/72−27/72=?

The two fractions now have like denominators so you can subtract the numerators.

Then:

38−27/72=117/2

This fraction cannot be reduced.

Therefore:

1936−38=11/72

Solve for f
-f + 2+ 4f = 8 - 3f

Answers

Answer:

f = 1

Step-by-step explanation:

-f + 2 + 4f = 8 - 3f

First, I'll add like terms.

2 + 3f = 8 - 3f

Then, I'll add 3f on both sides.

2 + 6f = 8

Next, I'll subtract 2 on both sides.

6f = 6

Finally, I'll divide 6 on both sides.

f = 1

Therefore, f = 1.

Standard to slope intercept form.

Answers

First bring the 2x to the other side:

2y = -2x + 16

Then divide by 2 to get y by itself, which the answer is

y = -x + 8


The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation 2x + 2y = 16 in slope-intercept form is

y = -x + 8.

Where slope = -1 and y-intercept is 8

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

We have the equation as,

2x + 2y = 16

We need to convert in the form of y = mx + c.

Subtract 2x on both sides.

2y = -2x + 16

Divide both sides by 2.

y = (-2x + 16) / 2

y = -x + 8

This is in the form of slope-intercept form.

Where slope = -1 and y-intercept is 8

Thus,

The equation 2x + 2y = 16 in slope-intercept form is

y = -x + 8.

Where slope = -1 and y-intercept is 8

Write an equation for a line that is parallel to y = -3x – 5 that goes through the point (-1, 8)

Answers

Answer:

y = -3x +5

Step-by-step explanation:

Parallel means that both slopes are the same.

This gives us y = -3x + C so far.

To find the y-intercept, we need to get x to 0.

Since we know the point (-1, 8), we can plug the number in into our equation

y = -3x + C.

8 = -3(-1) + C

8 = 3 + C

8 - 3 = C

5 = C or C = 5.

Now plug in C into our unsolved equation to get y = -3x +5.
