Answer:

1: slope: 2 points: (2,1)

2: plot the points with the slope equation: y=mx+b. 3: 1=2(2)+b 4: 1=4+b. 5:1-4=b ————- -3=b Equation: y= 2x-3

Answer:

y=2x-3

Step-by-step explanation:

show work

1=(2*2)+b

1=4+b

1-4=-3

-3=b

check work

y=2x-3

y=(2*2)-3

y=4-3

y=1

What is the slope of the line y = 3?
CaHeK987 [17]
The slope would be 0. Because the line would be flat if all of the y values equal 3, that means the slope = 0. If now x=9 or anything like that, that would be undefined,

I hope this helped! If it does then please thank, rate, and give brainliest answer!

Please simplify the expression.
IRINA_888 [86]

Answer:

1) 15a - 15c + 3

2) -7n + 31 + 13m + 7p  or  13m - 7n + 7p + 31

3) 44x + 6y + 3

4) 9m - 6n + 23

Step-by-step explanation:

1. Add like terms. 6a + 9a=15a. -8c - 7c=-15c

2. Add like terms. You can rearrange them in descending order based off of exponents and variables.

3. Multiply what's in parentheses first (distribute the 6). It should end up being (6y + 42x). Then you add like terms and put in descending order.

4. Distribute the (-3) to what in the parentheses. It should end up being (-6n + 15 - 3m). Then you add like terms and put the expression in descending order.

Please Help!!
expeople1 [14]

A = P(1 + rt)

Where:

<span>·         </span>A = Total Accrued Amount (principal + interest)

<span>·         </span>P = Principal Amount

<span>·         </span>I = Interest Amount

<span>·         </span>r = Rate of Interest per year in decimal; r = R/100

<span>·         </span>R = Rate of Interest per year as a percent; R = r * 100

<span>·         </span>t = Time Period involved in months or years

A = 15,000(1+ 0.07(5))

A = 20,250 they acquired in total for 5 years

The yearly amount the get is 15,000 xx 0.07 = $ 1050 per year

So in the next 25 years addition of 1050x25 = $26250 they will get

Jessica wants to plan where she will place furniture in her room, so she has drawn a scale model of her room in order to begin p
Setler79 [48]
To solve this problem you must apply the proccedure shown below:
 1. You have that:
<span> - The scale model is 11 inches long and 8.5 inches wide.
 - The door to her room takes up 1.75 inches.
 - The longest wall in Jessica’s actual room is 15 feet long.
 2. Therefore, the actual size of the door is:
 15 feet=180 inches
 1.75 inches(180 inches/11 inches)=28.63 inches
 3. If the door in completely open, you must apply the formula for calculate the area of a semicircle:
 A=</span>πr²/2
 r=28.63 inches
 A=π(28.63 inches)²/2
 A=1288.11 inches²
 The answer is: 1288.11 inches²
