What we know: Hannah buys 2/3 LB

Uses 1/4 LB

Well, the word "left" tells you that you would have to subtract 1/4 from 2/3. This is when you will have to find out the Least Common Denominator for both fractions.

Now, just subtract:
2/3-1/4

And you will end up with an answer of 5/12.

Take LCD of 3 and 4 = 12
(2 *4)/12 - (1*3)/12
8/12 - 3/12
= 5/12 pound of roast beef is left.

A line is graphed below. Write an equation in the form y = mx + b that represents this line

galben [10]

<h3>Explanation</h3>

Slope-Intercept form

$y = mx + b \\ m = slope \\ b = y - intercept$

Calculate the slope with two given coordinate by using rise over run.

$\begin{cases}(x_1,y_1) = ( - 4,0) \\ (x_2,y_2) = ( 0,2) \end{cases}$

These two coordinate points are part of the graph and can be used to find the slope.

$m = \frac{y_2 -y_1 }{x_2 - x_1}$

Substitute the coordinate points in the formula.

$m = \frac{2 - 0}{0 - ( - 4)} \\ m = \frac{2}{ 4} \\ m = \frac{1}{2}$

Therefore, the slope is 2.

Rewrite the equation in slope-intercept.

$y = \frac{1}{2} x + b$

Calculate the y-intercept by substituting any given points in new rewritten equation.

$(x,y) = ( 0,2)$

I will be substituting these coordinate points in the equation.

$y = \frac{1}{2} x + b$

Substitute x = 0 and y = 5 in the equation.

$2 = \frac{1}{2} (0) + b \\ 2 = 0 + b \\ 2 = b$

Therefore the y-intercept is (0,2).

Rewrite the equation.

$y = \frac{1}{2} x + 2$

<h3>Answer</h3>

 $\large \boxed{y = \frac{1}{2} x + 2}$

In ΔDEF, m∠D = 103° and m∠E = 14°. Which statement about the sides of ΔDEF must be true?

UkoKoshka [18]

The statement that we can make that must be true about the sides of ΔDEF is: EF > DE > DF.

<h3>Triangle Sides and angles Relationship</h3>

The length of the three sides of a triangle is relative to the measure of the size of the angle opposite to each of he sides.
That is, the longest side will be directly opposite the largest angle and vice versa.

Thus, the statements about the sides of ΔDEF are missing, however, we can make the following deductions:

m∠D = 103° is opposite to the longest side EF.
m∠F = 63° (180 - 103 - 14) is opposite to the medium side DE
m∠E = 14° is opposite to the shortest side DF.

Therefore, the statement that we can make that must be true about the sides of ΔDEF is: EF > DE > DF.
