Mathematics
1 answer:
Alexxx [7]3 years ago
8 0

Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

A line includes the points (0,0) and (1,5). What is its equation in slope-intercept form
Kipish [7]

9514 1404 393

Answer:

  y = 5x

Step-by-step explanation:

The point (0, 0) tells you the line goes through the origin, so represents a proportional relationship. The slope is simply the ratio of y to x, or 5/1 = 5.

The equation of the line is ...

  y = mx + b . . . . . . line with slope m and y-intercept b

  y = 5x . . . . . . . . . . line with slope 5 and y-intercept of 0 (the origin)

Put the equation in standard form with a positive x coefficient y - 1 = 5/6 (x-4) ​
Anon25 [30]

Answer:

5x - 6y = 14

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

given

y - 1 = \frac{5}{6}(x - 4)

Multiply through by 6 to eliminate the fraction

6y - 6 = 5(x - 4) ← distribute

6y - 6 = 5x - 20 ( add 20 to both sides )

6y + 14 = 5x ( subtract 6y from both sides )

14 = 5x - 6y , thus

5x - 6y = 14 ← in standard form

Solve tor r.<br> *a(5 – x) = bz - 8
Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Assuming the given equation is

a(5 - r) = bz - 8

To solve for r, we first divide both sides by a.

5 - r = \frac{ bz - 8}{a}

We now subtract 5 from both sides:

- r = \frac{ bz - 8}{a}  - 5

We now divide through by - 1 to get:

r = 5 - \frac{ bz - 8}{a}

Or

r = \frac{5a -  bz + 8}{a}  \:  \: where \: a \ne0

11/2=21/2/5/2(9/2)+b<br> Solve for b
____ [38]
We can times 5/2 and 9/2. And then divide that number with 21/2.
Then we can get 15/14.
We can subtract 15/14 from 11/2.
b=31/7
