How do you convert 14x + 19y = 20 into slope intercept form?

Answers

Subtract 14x from both sides. Then divide both sides by 19

[tex]14x + 19y = 20\\\\19y = 20-14x\\\\19y = -14x+20\\\\y = \frac{-14x+20}{19}\\\\y = \frac{-14x}{19}+\frac{20}{19}\\\\y = -\frac{14}{19}x+\frac{20}{19}\\\\[/tex]

The equation is now in slope intercept form y = mx+b

m = -14/19 is the slope

b = 20/19 is the y intercept

-1/3(24+3)-1
i need help please
it is 24 points

Answers

Um -1/3(24+3)-1 = -10

So -10 is the answer
I saw someone answered but didn’t explain first you have to do the equation inside the parentheses so 24+3 so the equation is then -1/3(21)-1 and then you do the multiplication which is -1/3*21 which is -7 so then it’s -7-1 which is -8

I also need to show my work so if somebody could help explain how i do that i’d appreciate it.

Answers

Answer:

<A = 68° <B = 44°

Step by step:

(the picture)

To find the value of x you u have to add all angles

68 + x + (x - 24) = 180

Remove parenthesis

68 + x + x - 24 = 180

Combine like terms

44 + 2x = 180

Get x on one side of the equation

44 + 2x = 180
-44 -44


2x = 136


Divide each side by 2 to isolate x


2x/2 = 136/2

x = 68


now that you have x you can put it into the equations

A = 68°

B = (x - 24)
B = (68 - 24)

B = 44°

Solve For X: 2.37 = 0.58 + X

Answers

A scale model of a boat is 6 inches long. The actual boat is 42 feet long. Which statement(s) are true??

Answers

Answer:

B. 1 in = 7 ft

Step-by-step explanation:

Since on the scale the boat was 6 inches and the actual boat was 42 feet, we need to divide to see how many feet correlate to the number on inches on the scale. So we do 42 / 6, which equals 7. This means that for every inch on the scale, it will be 7 feet in real life.

the answer is B. hope this helps

pls help I'm stuck, I would like an explanation if possible!

Answers

Answer:

60

Step-by-step explanation:

So they are showing you a chart in which the column y is determined by the column x, so you divide y/x in any of the rows so that you get the relation.

100/4=25 (which is the same for every row)

It works pretty much the same for the graph, but the relation is different.

Now instead of a chart you have to figure out the values of x and y by looking at the points that make up the line. For example we have a point that is in the coordinate (2, 60), and that represents that the x value is 2 and its correspondent y is 60. And to find the relation we do it as in the first step but now with 2 and 60.

60/2=30 (which is the same for every point)

Finally we just calculate the value of y both in the graph and the chart when x=12

So for the chart: 12*25= 300

And for the graph: 12*30= 360

The difference between those two is 60.

The following graph represents and linear equation. (Will give brainlest :))

Answers

Answer:

C

Step-by-step explanation:

The y intercept is positive 2 so that eliminates two options. To find the slope you have to find a two points on a graph. And found the boxes

The answer is D
Substitute x= 0 and y=2 into the equation,
Left hand side= 2
Right hand side= 3(0)+2= 2

Because LHS= RHS, (0,2) is the solution of the equation y=3x +2

Therefore, the equation y=3x+2 represents the graph.

How do you convert 20x + 9y = 9 into slope intercept form?

Answers

Answer:

[tex] y = - \frac{20}{9} x + 1 [/tex]

Step-by-step explanation:

[tex]20x + 9y = 9 \\ \\ 9y = - 20x + 9 \\ \\ y = - \frac{20}{9} x + \frac{9}{9} \\ \\\purple {y = - \frac{20}{9} x + 1} \\ this \: is \: the \: required \: \\slope \: - intercept \: form \\ \ \\ where \: \\ slope \: = - \frac{20}{9} \\ \\ y - intercept = 1[/tex]

20x+9y=9

First, the formula for slope intercept is y=mx+b
So, in order to get it in the slope form we have to subtract 20x from both sides.
We end up with, 9y=-20x+9
We have to get rid of the 9 so we divide.
9y=-20x+9
/9 /9. /9

The inequality can be read as x is greater than 0

-3, -0.01, and -1/5 are all values that are less than 0

So if these are the values of x, then the inequality would be false.
