Answer:

1 $\frac{7}{20}$

Step-by-step explanation:

1. Convert the mixed number to an improper fraction to match the rest of the problem (this just makes it easier for now, the answer will still be a mixed number)

-1 $\frac{4}{5}$ becomes $\frac{9}{5}$

2. Re-write the new equation. When there is a "+" in front of a set of parentheses the expression doesn't change aside from removing the plus signs.

The new equation becomes

$\frac{9}{5} - \frac{1}{4} -\frac{1}{5}$

3. Calculate. Just work out the new expression.

The answer is $\frac{27}{20}$

4. Convert to a simplified mixed decimal.

27 goes into 20 once with seven left over, making the answer 1 $\frac{7}{20}$

33 is 15less than k.

RoseWind [281]

Answer:

k = 48

Step-by-step explanation:

Given expression:

33 is 15 less than k

Convert this into equation and solve for k:

33 = k - 15
k = 33 + 15
k = 48

So the <u>value of k is 48</u>

The table below represents a function. Which of the following equations could be its function rule?

worty [1.4K]

Answer:

$y=2x-2$ is the required equation.

Therefore, the second option is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation of a linear function is given by

$y=mx+b$

where m is the slope and b is the y-intercept

Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)$

$m=\frac{0-\left(-2\right)}{1-0}$

$m=2$

substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.

$y=mx+b$

$-2 = 2(0)+b$

$-2=0+b$

$b=-2$

Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function

$y=mx+b$

$y=2x+(-2)$

$y=2x-2$

Thus, $y=2x-2$ is the required equation.

Therefore, the second option is true.
