Slope = (y2 - y1)/(x2 - x1)

= (3/4 - 3) / (2 - 1/2)

= (3/4 - 12/4) / (8/4 - 2/4)

= (-9/4) / (6/4)

= (-9/4) × (4/6)

= -9/6

= - 3/2

Answer

A. -3/2

The answer is A.

We have to find the difference between the cooridants.

1/2-2= -1 1/2 = -3/2

3-3/4 = 2 1/4 = 9/4

We then divide 9/4 by -3/2 (9/4 times -2/3) and we get -18/12 if we divide the top and bottom by 6, we get -3/2.

Graph y=x, y=2x, and y=3x on the same coordinate plane. How are the graphs alike? How are they different? Compare the slopes.

Ne4ueva [31]

Answer:

all the three graphs passes through the origin (0,0)

the slope of the lines are different.

for y=x equation , slope =1

for y=2x equation slope = 2

for y=3x equation slope = 3

Step-by-step explanation:

LEts graph all the three equations

y=x , y=2x, y= 3x

Make a table for each equation and find two points

x y=x x y= 2x x y=3x

0 0 0 0 0 0

1 1 1 2 1 3

Graph is attached below

From the graph we can see that , all the three graphs passes through the origin (0,0)

From the graph we can see that the steepness of the line changes for each line. steepness of the line is noting but the slope . So the slope of the lines are different.

Given equation is in the form of y=mx+b

m is the slope

for y=x equation , slope =1

for y=2x equation slope = 2

for y=3x equation slope = 3

Alex buys a palm tree that has a price tag with $65, but he found a coupon that has a discount of 25%. How much will Alex pay af

igor_vitrenko [27]

Answer:

Alex will pay $48.75 after the discount.

Step-by-step explanation:

With the information provided, in order to find the amount Alex will pay after the discount, first, you have to find the amount of the discount by calculating 25% of the price and then, you have to subtract that discount from the price:

$65*25%=$16.25

$65-$16.25=$48.75

According to this, the answer is that Alex will pay $48.75 after the discount.

Solve the equation <br> 14(3x-1)=2x-23

irina1246 [14]

Answer:

$x=\frac{-9}{40} \\$

Step-by-step explanation:

Given Equation:

$14(3x-1)=2x-23$

Solving the bracket on L.H.S

$(14)(3x)-1(14)=2x-23$

$42x-14=2x-23$

Taking the terms of 'x' to one side and the constants to other side

$42x-2x=-23+14\\\\40x=-9\\\\x=\frac{-9}{40} \\$

The value of 'x' after solving the equation is:

$x=\frac{-9}{40} \\$

The current value of a baseball card is 50 times its original value v (in dollars). The baseball card is worth $62. Write and so

ehidna [41]

If the current value of the baseball car is 50 times its original value, its original value will be its current value divided by 50.

Let $v$ represent the current value of the baseball card. We know form our problem that $62 is 50 times the original value, $v$ , of the baseball card, so translating this statement to an equation we get:
$62=50v$
$v= \frac{62}{50}$
$v=1.24$

We can conclude that the original value of the baseball card was $1.24.
