What is the equation of this line?
y= 2x - 3
y= 3x - 2
y= 1/3x - 2
y= 1/2x - 3

Answers

Answer:

y= 3x - 2

Step-by-step explanation:

The line passes through (0, -2). '-2' is the y-intercept.

The line passes through the points (2,4) and (1,1).

[tex]m=\frac{rise}{run}=\frac{1-4}{1-2}=\frac{-3}{-1}=3[/tex]

The equation should be y= 3x - 2.

Hope this helps.

y = 3x - 2 is the answer.

In 1968 it cost $54 000 for a 30-second commercial during the super bowl. In 1973, the cost for a 30-second commercial was $88,000. What is the percent increase, rounded to the nearest whole number, in the cost for a 30-second commercial from 1968 to 1973?

Answers

Answer:

63 %

Step-by-step explanation:

Percentage change in value value for any number is given by

percentage change = (new value - old value) /old value * 100

we can also write it as

percentage change = (change in value ) /old value * 100

________________________________________

cost of commercial in 1968 = $54000

cost of commercial in 1973 = $88000

change in cost of commercial = cost of commercial in 1973 - cost of commercial in 1973  = $(88000-54000) = $34000

thus,

percentage change in cost of commercial

         = change in cost of commercial/cost of commercial in 1968 * 100

         = 34000/54000*100 = 62.96 %

Thus, percentage change in cost of commercial is 62.96 %

we have to round it to nearest whole number

rounded value of 62.96 is 63

in that case

percentage change in cost of commercial is 63 %

Luca ma kilka 10-centówek oraz kilka 5-centówek. Razem ma 40 monet, o wartości
3.15 Euro. Ile monet każdego rodzaju ma Luca?

Answers

d = liczba monet 10-centowych

p = liczba monet 5-centowych

Razem, Luca ma 40 monet:

d + p = 40

Jedna 10-centowa moneta ma wartość 10 centów, i jedna 5-centowa ma wartość 5 centów, więc

10d + 5p = 315

bo 3,15 euro = 315 centów.

Znajdź d i p :

(10d + 5p) - 5(d + p) = 315 - 5•40

5d = 115

d = 23

d + p = 40

23 + p = 40

p = 17

How do I find x and what’s the relation ?

Answers

Answer:

X=17

Step-by-step explanation:

Im sorry if this sounds a bit confusing. Im better at doing the math then explaining it. All the angles in that are 90-degree angles and because of that, you can assume that the angle that you trying to find is also 90 degrees. So to find that equation you can do this.

4x+22=90 -22 from both sides.

-22=-22  

you are left with

4x=68 then divide 4 from both sides.

/4=/4

you then get x=17 which is your answer.

Check your answer by plugging 17 into x.

4*17+22=90

The answer is 90 so you are correct.

The graph of linear function g passes through the points (3, 7) and (9, 3).
Which statement must be true?
A. The graph of g passes through the point (6,-2)
B. The zero of g is -6
C. The slope of the graph is -2/3
D. The x-intercept of the graph of g is 6

Answers

Answer:

c

Step-by-step explanation:

The slope of the graph is -2/3 is true.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁.

The graph of linear function g passes through the points (3, 7) and (9, 3).

We need to find which statement is true from options.

Slope=3-7/9-3

=-4/6

=-2/3

The slope intercept form 7=-2/3(3)+b

7=-6/3+b

7=-2+b

b=9

Hence, the slope of the graph is -2/3 is true.

What is the solution to the equation –5w + 3 = 4w – 6?

Answers

Answer:

-2=2

Step-by-step explanation:

Answer:

w = 3

Step-by-step explanation:

-5w + 3 = 4w - 6

were going to get the variable and the numbers on different sides

-5w + 3 - 3 = -5w

4w - 6 - 4w = -6

-5w + 4w = -1w or -w

-6 + 3 = -3

-w = -3

and since there're both negatives you can just take that away and you get

w = 3

150+25x=55x what is the answer?

Answers

Answer:

x = 5

Step-by-step explanation:

150+25x= 55x

      -25x  -25x

150= 30x

150/30 = 30x/30

x = 5

Hope this helps!

Answer: x =5

Steps: 150 + 25x = 55x

Subtract 150 from both sides: 150 + 25x - 150 = 55x - 150

Simplify: 25x = 55x - 150

Subtract 55x from both sides: 25x - 55x = 55x - 150 - 55x

Simplify: -30x = -150

Divide both sides by -30:  -30x ÷ -30 = -150 ÷ -30

Simplify: x = 5

Answers

Answer:

B) n=-2

Step-by-step explanation:

First, distribute.

7(1+4n)-5=-38+8n

7+28n-5=-38+8n

Combine like terms.

2+28n=-38+8n

To make solving the equation easier, subtract 8n first, so there isn't a negative variable.

2+28n=-38+8n

  -8n           -8n

2+20n=-38

Subtract 2 on both sides.

2+20n=-38

-2          -2

20n=-40

Divide by 20 on both sides.

20n=-40

/20   /20

n=-2
