enot [183]

Answer: $0.20

Step-by-step explanation: $8.4 divided by the 24 or 2 dozen dougnuts she sells means she sell each donut for $0.35 and if we know that Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut then $0.35 - $0.15 = $0.20 to make each donut

Answer:

y = -5

Step-by-step explanation:

The coordinate point is in the format (x, y)

Therefore, the y-value of (4, -5) is -5

So the equation of the horizontal line is therefore y = -5

Line m includes the points (-3, 3) and (-4,-6). Line n has the same slope as line m and

Sveta_85 [38]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

The slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

We have that the line m passes through the following points:

$(x_ {1}, y_ {1}): (-3,3)\\(x_ {2}, y_ {2}): (-4, -6)$

So, the slope of the line m is:

$m = \frac {-6-3} {- 4 - (- 3)} = \frac {-9} {- 4 + 3} = \frac {-9} {- 1} = 9$

Line n has the same slope so the equation is of the form:

$y = 9x + b$

We have as data that the y-intercept is $-\frac{2} {3}$ . Thus, we have that the equation of line n is:

$y = 9x- \frac {2} {3}$

ANswer:

$y = 9x-\frac {2} {3}$

In the picture shown below, what proportion would NOT give the correct value of x?

Temka [501]

Answer: (c)

Step-by-step explanation:

In the given figure, two triangles are similar namely $\triangle ABC$ and $\triangle ADB$

For similar triangles, the ratio of the corresponding sides are equal.

For option (a), Hypotenuse to Perpendicular ratio is given, that is correct

Similarly for option (b), Perpendicular to hypotenuse ratio is given

Both option (a) and (b) gives the same value of $x$ that is,

$\Rightarrow x=\sqrt{81\times 45}\\\Rightarrow x=60.37$

Option (c) does not give the correct value of $x$
