The slope of an horizontal line is always zero.

This comes from the fact that the slope is given by:

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

and if two points lie on a horizontal line this means that their y components are equals and then the numerator is zero.

Therefore the slope is zero.

When you multiply a function by -1, what is the effect on its graph?

Dafna1 [17]

Answer:

B. The graph flips over the x-axis

Step-by-step explanation:

When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.

The graph flips over the x-axis.

Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.

New York City is approximately 205 miles from Washington, D.C. How far apart will these cities appear on a map with the scale 1

gavmur [86]

Answer: 4.1 inches

Step-by-step explanation:

From the question, we are informed that New York City is approximately 205 miles from Washington, D.C.

The distance that these cities will appear on a map with the scale 1 in: 50 miles will be represented by x.

Therefore, x:205 = 1:50

Cross multiply

x/205 = 1/50

50x = 205

x = 205/50

x = 4.1 inches

The answer is 4.1 inches

insens350 [35]

Answer: $13,475

Step-by-step explanation:

1st hour: 350 people bought tickets --> 350 × $17.50 = $6,125

2nd hour: 350(1.2) people bought tickets --> 350(1.2) × 17.50 = $7350

Total amount = 1st hour + 2nd hour

= $6,125 + $7,350

= $13,475

Help !! I can't understand it

siniylev [52]

a.) The color of Aqueous solution turns light green from blue, due to formation of iron sulphate .

b.) The color of the Aqueous solution turns colorless from blue due to formation of zinc sulphate.

2. Bells used in temples aren't made up of wood because wood isn't sonorous and hence can't produce ringing sound, and hence metals are used in making bells.

3. phosphorous is kept in water because it is highly reactive and reacts vigorously with air if left free in atmosphere .

a.) CuSO4 + Mg =》MgSO4 + Cu

this is a single displacement reaction, where Magnesium being more reactive than Copper, displaces copper from its compound (copper sulphate) to form magnesium sulphate.

b. H2SO4 + Zn =》ZnSO4 + H2

this is a single displacement reaction,

where Zinc being more reactive than

hydrogen, displaces hydrogen from its

compound (sulphuric acid) to form Zinc sulphate.
