Find the Equation of a Line Given That You Know Its Slope and Y-Intercept. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know the slope (m) any y-intercept (b) of a line, this page will show you how to find the equation of the line.

Step-by-step explanation:

9514 1404 393

Answer:

  y = -x +7

Step-by-step explanation:

The slope-intercept form of the equation for a line is ...

  y = mx +b

where m is the slope and b is the y-intercept.

Put the given values in the corresponding places:

  y = (-1)x +7

  y = -x +7

Answer:

3

Step-by-step explanation:

The equation [ y = 3x - 4 ] is written in slope-intercept form [ y = mx + b ].

m = slope

b = y-intercept

The variable "m" in the given equation is 3, thus makes it the slope.

Answer:

0.0375 gram of Vitamin C

Step-by-step explanation:

Hi there !

1  1/2 tablets = (1*2 + 1)/2 = 3/2 tablets every day

How many grams of vitamin C do do you take every day?

1/40 × 3/2 = 3/80 = 0.0375 gram of Vitamin C

Good luck !

Answer:

31.5 days

Step-by-step explanation:

We.solve using z score formula

z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

The 5th percentile z score = -1.645

Mean = 66

Standard deviation = 21

Hence:

-1.645 = x - 66/21

-1.645 × 21 = x - 66

-34.545 = x - 66

-34.545 + 66 = x

x = 31.455 days

Approximately to the nearest round integer

= 31.5 days

Therefore, driver use a commuter rail line 31.5 days annually to be in the top 5% of rail users

Answer:

It took 13 days and a half to escape

Step-by-step explanation:

This is a classic problem where the first answer that comes to one's mind is not the correct answer.

The ant climbs up 8 cm per day and slips down 4 cm every night. It means the real distance the ant goes up is 8 - 4 = 4 cm per day. Since the total distance is 60 cm, it could lead us to think the time needed to escape from the bottle is 60/4=15 days. This is wrong, as we'll prove below.

Assume the last day, the ant climbs up the final 8 cm and escapes. We don't know yet when, but we can assure that day the ant was at a height of 60 - 8 = 52 cm.

That 52 cm was the result of the 4 cm per day the ant effectively went up, thus it needed 52/4=13 days to reach that height.

At 13 days, the ant was at 52 cm, the day 14 it climbed up the final 8 cm and escaped.

Answer: It took 13 days and a half to escape

Answer:

3/10 ÷ 7/9=3/10 x 9/7 is the true one

Step-by-step explanation:

4/5 x 4/5 = 16/25 not 1 so this statement is wrong.

3/10 ÷ 7/9=3/10 x 9/7, this is the true statement and it equals 27/70

9/12 x 12/9= 1 not 0

1/2 ÷1/2= 1 not 1/4

Answer:

b = 3 in

Step-by-step explanation:

The area (A) of a rectangle is

A = lb ( l is the length and b the breadth )

Here A = 24, l = 4 and breadth = b + 3 , thus

4(b + 3) = 24 ( divide both sides by 4 )

b + 3 = 6 ( subtract 3 from both sides )

b = 3

Thus the width of the message is 3 in

Answer:

x=7.5

Total area = 27+15 = 42

Step-by-step explanation:

For question 13, we still need to find the bottom side of the T-shape that's not labeled. That's just 9-3.5-3.5=9-7=2.

Now that we know all the side lengths, we can set up an equation where all the side lengths add up to 39, and solve for x:

9+3+3+3.5+3.5+x+x+2=39

24+2x=39

2x=15

x=7.5

For question 14, we can divide the shape into 2 rectangles, which is shown in the picture attaches. Then, we just solve for each rectangle's area separately, and then add them up.

Rectangle A = 9*3=27

Rectangle B = 7.5*2=15

Total area = 27+15 = 42

Answer:

A

Step-by-step explanation:

They both have 2 areas shaded, have the same amount of parts and are the same size

Answer:

60+9h=375

Step-by-step explanation:

60+9h=375 just use math

The equation which represents the statement "Sixty more than 9 times a number is 375" is 9h + 60 = 375.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression.

The given statement is "Sixty more than 9 times a number is 375".

Since the number is h, the statement written in mathematical form is:
9h + 60 = 375

Hence, the equation which represents the statement "Sixty more than 9 times a number is 375" is 9h + 60 = 375.

Answer:

its D

Step-by-step explanation:

got it correct on a test :)

The correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.

The linear equation is an equation where the highest degree of the variables used in the equation is 1.

For example 9x+5=23

Given the equation is -1.3 +4.6x= 0.3+ 4x

In order to the linear equation first, try to keep the constant and the variable part to one side by adding or subtracting the constant term.

Then divide the coefficient of the variable (if the coefficient is not equal to 1) on both sides.

Here the given equation is -1.3 +4.6x= 0.3+ 4x

Step-1: Adding 1.3 to both sides of the equation

⇒-1.3 +4.6x +1.3 = 0.3+ 4x +1.3

⇒4.6x = 4x+1.6

Step-2: subtracting 4x from both sides of the equation

⇒4.6x -4x = 4x+1.6-4x

⇒ 0.6x=1.6

Step-3:  dividing both sides by the coefficient of x i.e. 0.6.

⇒0.6x/0.6 = 1.6/0.6

⇒x= 2.67

Therefore the correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.

Answer:

11.5 years

Step-by-step explanation:

The formula for the monthly payment of a loan is:

[tex] A = P\dfrac{r(1 + r)^n}{(1 + r)^n - 1} [/tex]

where

A = monthly payment

r = interest rate per period

n = number of periods

Assuming a monthly payment, we have

P = 17500

r = 0.065/12

The total amount of payments is the monthly payment times the number of payments, so

An = 24893.75

We can try 10 years. n = 10 * 12 = 120

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{120}}{(1 + \frac{0.065}{12})^{120} - 1} = 198.71 [/tex]

An = 198.71 * 120 = 23845.08

The total amount of payments is too low.

Let's try 11 years.

n = 11 * 12 = 132

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{132}}{(1 + \frac{0.065}{12})^{132} - 1} = 185.92 [/tex]

An = 185.92 * 132 = 24540.90

The total amount of payments is still too low.

Let's try 12 years.

n = 12 * 12 = 144

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{144}}{(1 + \frac{0.065}{12})^{144} - 1} = 175.34 [/tex]

An = 185.92 * 144 = 25248.41

The total amount of payments is too high.

11 years is too little, and 12 years is too much.

Let's try 11.5 years.

n = 11.5 * 12 = 138

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{138}}{(1 + \frac{0.065}{12})^{138} - 1} = 180.39 [/tex]

An = 180.39 * 138 = 24893.20

11.5 gives a total of payments of $24,893.20 which is very close to $23.893.75.

Answer: 11.5 years

The total amount of payments is too high.

Answer:

Step-by-step explanation:

Because if you change it from (43 + 60) + 40 to (60 + 40) + 43 = 143

You automatically know it is 143 because 60 + 40 is 100 + 43 = 143

And it wouldn't be D because that is already in a easy way the solve. The others looked to complicated to even attempt so it has to be A.
