Rewrite the equation y – 4x = –9 in slope-intercept form. simple explanation and proof

Answers

Answer 1

Answer:

y=4x-9

Step-by-step explanation:

add 4x to both sides to isolate y

Answer 2

Answer:

The slope-intercept form of this equation would be y = 4x - 9.

(For explanation look down below)  

Step-by-step explanation:

Slope-intercept form would be an equation that would look like...

y = mx + b

Where m is the slope and b is the intercept. From this form, we can understand that all we need to do is rearange the formula in a way that positive y would be on its left side. And so we get...

y - 4x = - 9

y - 4x + 4x = - 9 + 4x

y = 4x - 9

Jim buys some tacos and burritos which cost him $15.75. John buys some tacos and burritos which cost him $8.25. Tacos cost $1.50 each and burritos cost $2.25 each, how many of each did Joe and John buy?

Let t = the number of tacos and b= the number of burritos.

1. Which equation represents Joe?

2. Which equation represents John?

3. John bought:

tacos

burritos

4. Joe bought:

tacos

burritos

Answers

For John, the equation would be 1.5t + 2.25b = 8.25. For Jim, the equation would be 1.5t + 2.25b = 15.75. John bought one Burrito and 4 tacos. Jim bought 3 burritos and 6 tacos

THE ANSWER IS: y=3/2x+1

to find a line that is perpendicular, invert the slope and multiply by -1
so the original slope is -2/3,
invert it to get -3/2 then multiply by -1 to get 3/2

put the given point (-2,-2) and the new slope into point intercept form: y+2=3/2(x+2)

rewrite in standard form to get y=3/2x+1

The ratio of 15 days to a week is​

Answers

Answer :

The ratio of 15 days to a week is 15 : 7.

[tex] \\ [/tex]

Explanation :

Ratio of 15 days to a week :

[tex] \sf : \implies 15 \: days : 1 \: week = \dfrac{15 \: days}{1 \: week}[/tex]

[tex] \\ [/tex]

Now, we know that 1 week has 7 days.

[tex] \sf : \implies 15 \: days : 1 \: week = \dfrac{15 \: \cancel{days}}{7 \: \cancel{days}}[/tex]

[tex] \sf : \implies 15 \: days : 1 \: week = \dfrac{15}{7}[/tex]

[tex] \sf : \implies 15 \: days : 1 \: week = 15 : 7[/tex]

[tex] \\ [/tex]

Hence, The ratio of 15 days to a week is 15 : 7.

Half of Ethan string is equal to 2/3 of Kayla stream the total length of the string is 10 feet how much longer is Ethan string Kayla string

Answers

Answer:

10/7 feet

Step-by-step explanation:

Let e = Ethan

k = Kayla

The following equations can de derived from the equation :

1/2 e = 2/3k

multiply both sides of the equation by 2

e = 4/3k --- 1

e + k = 10 --- 2

Substitute for e in equation 2

4/3k + k = 10

7/3k = 10

multiply both sides of the equation by 3/7

k = 30/7

Substitute for k in equation 1

e = (4/3) x 30/7 = 40/7

difference in length = 40/7 - 30/7 = 10/7

y = - 6x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 9) and (x₂, y₂ ) = (0, - 3)

m = [tex]\frac{-3-9}{0+2}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6

The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = - 6x - 3 ← equation of line

You are walking in the woods when you spot a bald eagle high up in a tree. You measure the angle of elevation to the eagle to be 67 degrees. You then walk directly to the tree and determine that you were standing 150 ft from the tree when you saw the bald eagle. How high up in the tree was the bald eagle?

Answers

Answer:

Step-by-step explanation:

infinite

The height of up in the tree was the bald eagle is, 352.5 feet

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

You measure the angle of elevation to the eagle to be 67 degrees.

And, The angle of elevation to the eagle to be 67 degrees.

Now, Let the height of up in the tree was the bald eagle is, x

Hence, We can formulate;

⇒ tan 67° = x / 150

⇒ 2.35 = x / 150

⇒ x = 2.35 × 150

⇒ x = 352.5 feet

Thus, The height of up in the tree was the bald eagle is, 352.5 feet

Answer:

Point A = (0,1)  Point B = (1,2)  Point C = (2,4)

Step-by-step explanation:

To find a point's "ordered pair" (x and y coordinates), consider each line a single digit unless the problem states/shows otherwise (ex. if the lines were evidently counting by 2's). Here, we can see each line represents a single digit. First count how many lines to the left/right of the y axis the point is (this will be your x point - ex. point B in this problem has an x valued at 1 because the point was one line to the right of the bold vertical line in the middle (the y axis). If the point is to the left, it is a negative x value, right would be positive, and if the point is on the y axis line. x is 0. You are essentially counting how far along the x axis the point is. Same applies to the y values, given you do the opposite and count how far from the x axis (horizontal bold line) the point is. Above that line is positive, below is negative, and again, if the point is on the x axis (bold horizontal line), the y value is 0. Then simply fill your values in in their corresponding places in the brackets: (x,y).

Hope this helps :) I know math can be especially hard to grasp so it's always okay to ask for help/explanation.

Salma, joe, and alan sent a total of 106 text messages during the weekend, salma sent 9 fewer messages than alan. Joe sent 3 times as many messages as alan. How many messages did they each send?

Answers

Answer:

Salma, joe, and alan sent 14, 69, and 23 text messages respectively

Step-by-step explanation:

Given that Salma, joe, and alan sent a total of 106 text messages during the weekend, it means that

s + j + a = 106 where s, j, and a are the number of messages sent by Salma, joe, and alan respectively

Given salma sent 9 fewer messages than alan

s = a - 9

Joe sent 3 times as many messages as alan

j = 3a

hence

a - 9 + 3a + a = 106

5a - 9 = 106

5a = 106 + 9

5a = 115

Divide both sides by 5

a = 115/5

= 23

s = 23 - 9

= 14

j = 3* 23

= 69
