Answer:

D. The slope of the graph will be zero.

Step-by-step explanation:

Slope of a line is given as $\frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1}$ .

For a horizontal line, the rise is always equal to zero since the line doesn't rise vertically. This means, $y_2 - y_1 = 0$ .

No matter the value of the run, $x_2 - x_1$ , when we divide zero by the value of the run, we would always have 0.

Therefore, the slope of an horizontal line would always be zero.

The ratio of dark chocolate candies to white chocolate candies is 4 to 3.

Elena L [17]

The answer is 18 are white chocolate.

Here is my proof

4 × 6 = 24 and 3 × 6 = 18 and I got 4 and 3 from the ratio of dark chocolate candies to white chocolate candies and I got the 6 from the multiplication chart that they both end up with the same number which is 6. So 18 is the answer

siniylev [52]

Answer:

AA similarity postulate

Explanation:

For triangle XZY, the angles are 90°, 40°, 50°.

For triangle AXB, the angles are 90°, 40°, 50°.

Which states that all the angles are of equal measure in the triangles.

This is stated by AA similarity theorem meaning when two angles are equal in the triangle. Then the triangles are congruent to each other.

Find the explicit formula that produces the given sequence. <br> 3/2, 3/4, 3/8, 3/16,...

lara [203]

$\frac{3}{2};\ \frac{3}{4};\ \frac{3}{8};\ \frac{3}{16};\ ...\\\\a_1=\frac{3}{2}\\\\a_2=\frac{3}{4}=\frac{3}{2}\cdot\frac{1}{2}\\\\a_3=\frac{3}{8}=\frac{3}{4}\cdot\frac{1}{2}=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^2\\\\a_4=\frac{3}{16}=\frac{3}{8}\cdot\frac{1}{2}=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^3\\\vdots$
$a_n=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^{n-1}=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^{-1}\cdot\left(\frac{1}{2}\right)^n=\frac{3}{2}\cdot2\cdot\left(\frac{1}{2}\right)^n=3\cdot\left(\frac{1}{2}\right)^n$
