hello!! how do you find y intercept

Answers

Answer:

you find the point where the line intersects

It’s the point on the line where it goes through the y axis

Solve the system by substitution

x=y

6x-3y=30

Answers

Answer: (x, y) = (10, 10)

Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

whats the percent increase from 45 to 56

Answers

24.44% hope that helps :)

Answer:

24.44%

Step-by-step explanation:

1) Find the difference between 45 and 56 as a number.

2) Divide the result from Step 1 by the starting number 45.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 45 to 56, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 45, and Y is the ending number 56 that it changed to. When we enter these numbers into the formula, we get:

((56-45)/45)*100 = 24.44%

Thus, the answer to the question "What is the Percent Change from 45 to 56?" is:

473 heartbeats in 5 1/2 minutes

Answers

Answer:

86 heartbeats per minute

Step-by-step explanation:

i assume that's your question?

the number of heartbeats per minute is 86.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 473 heartbeats in [tex]5\frac{1}{2}[/tex] = 11/2minutes

Number of heart beats per minute = Total number of heart beats ÷ Number of minutes

= 473÷ 11/2

= 473×2/11

= 43×2

= 86 beats per minute

Therefore, the number of heartbeats per minute is 86.

What is the slope of the line in the graph?

Answers

Answer: 1

Step-by-step explanation:

Slope=rise/run

Here we rise 2 and run 2

2/2=1

Answer:

Step-by-step explanation:

The first thing you would want to do is know that the slope is the change in y over the change in x. for this line, it goes up one, over one. so your slope is just one. if you were to write the slope-intercept form equation, it would be y=x+1

Two vertical angles have measures of (4x + 8) and (7x -22). What is the measure of the two angles?

Answers

Answer:

Step-by-step explanation:

Vertical angles are congruent

7x - 22 = 4x + 8 {Add 22 to both sides}

7x = 4x + 8 + 22

7x = 4x + 30 { subtract 4x from both sides}

7x - 4x = 30

3x = 30

x = 30/3

x = 10

4x + 8 = 4*10 + 8

= 40 + 8

= 48

7x - 22 = 7*10 - 22

= 70 - 22

= 48

5x + 3 = 2(x + 3) + 3x – 6

Answers

9514 1404 393

Answer:

no solution

Step-by-step explanation:

We can eliminate parentheses and collect terms.

5x +3 = 2x +6 +3x -6

5x +3 = 5x

3 = 0 . . . . . . . . subtract 5x from both sides

There is no value of x that will make this true. There is no solution.

Answer:

No solution

Step-by-step explanation:Does that make sense to u, You distribute 2 with x and 3 which gets you 2x+6. Combine like terms and you will get 5x on the right side, since the 6's cancel out. 5x+3=5x.

X cancels out and u are left with 3=nothing which makes it no solution

The sum of the numbers X, Y, and Z is 40. The ratio of X to Y is 1:2 and the ratio of Y to X is 2:5. What is the value of Y?

Answers

Step-by-step explanation:

Since X : Y = 1 : 2, X = 0.5Y.

Since Y : Z = 2 : 5, Z = 2.5Y.

We have X + Y + Z = 4Y = 40. Hence Y = 10.

[tex]y=10[/tex]

Ratio:A ratio in mathematics shows how many times one number is contained in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio of 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8 (or 3:4) (or 4:7).A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.Solution -

Given -

[tex]x+y+z=40\\x:y=1:2\\y:x=2:5[/tex]

To find - [tex]y[/tex]

Since,

[tex]x:y=1:2,x=0.5y\\y:x=2:5,z=2.5y\\x+y+z=4y+40\\y=10[/tex]

Therefore, [tex]y=10[/tex].
