Line 1 passes through the points -2,7 and 3,3. Line 2 passes through the points 5,1 and 9,1. Find the slope of each line. Which

RSB [31]

Answer:

The slope of the given line 1 is -4/5.

The slope of the given line 2 is 0.

The line 2 has a greater slope then line 1.

Step-by-step explanation:

The slope of a line with points (x1,y1) and (x2,y2) is given as:

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

Now, Here the, points of the line 1 are A (-2,7) and B (3,3)

So, here, the slope of line AB is $m = \frac{3 -7}{3-(-2)} = \frac{-4}{3 +2} = \frac{-4}{5}$

Hence, the slope of the given line 1 is -4/5.

Now, Here the, points of the line 2 are P (5,1) and Q (9,1)

So, here, the slope of line PQ is $m = \frac{1-1}{9-5} = \frac{0}{4} = 0$

Hence, the slope of the given line 2 is 0.

Now, as we can see 0 > ( -4 / 5)

So, the line 2 has a greater slope then line 1.

together, steve and tom sold 7777 raffle tickets for their school. steve sold 1414 more than twicetwice as many raffle tickets

storchak [24]

Steve = S , Tom = T
1) S+T = 7777
2) S= 1414 + 2T

put 2) in 1)

1414+2T + T = 7777
1414 +3T = 7777
3T = 6363
so T = 2121
then Steve sold 1414+2(2121) = 1414+4242=5656 tickets
while Tom sold 2121 tickets

The formula for electrical power (P, in watts) is where V is the voltage in volts and R is the resistance in ohms. For a particu

bazaltina [42]

Answer: 4 V

Step-by-step explanation:

The formula for electrical power $P$ is:

$P=\frac{V^{2}}{R}$

Where:

$P=0.5 W$ is the water heater electrical power

$V$ is he water heater voltage

$R=32 \Omega$ is the electrical resistance

Isolating $V$ :

$V=\sqrt{PR}$

$V=\sqrt{(0.5 W)(32 \Omega)}$

Hence:

$V=4 V$

Jude types 1,170 characters in 6 minutes. What is her typing rate in characters per minute? A. 200 characters per minute B. 197

Kisachek [45]

Answer:

Option C) 195 characters per minute

Step-by-step explanation:

We are given the following in the question:

Jude types 1,170 characters in 6 minutes..

We have to find the typing rate in characters per minute.

Thus can be done in the following manner:

Typing rate =

$=\dfrac{1170\text{ characters}}{6\text{ minutes}}\\\\=195\text{ characters per minute}$

Thus, Jude speed in characters per minute is

Option C) 195 characters per minute
