18 × [ 7+(-3) ] = [ 18 x 7] + [ 18 × (-3) ]​

Mathematics

Step-by-step explanation:

subtract 3 from 7 to get 4

18 x 4 = 18 x 7 + 18 (-3)

multiply 18 and 4 to get 72

72= 18 x 7 + 18 (-3)

multiply 18 and 7 to get 126

multiply 18 and -3 to get -54

72 = 126 - 54

subtract 54 from 126 to get 72

72 = 72

Find the slope intercept form of the equation of the line that’s has the given properties (1 , 3) m=1/4
Helga [31]

Answer:

y = 1/4x + 11/4

Step-by-step explanation:

Given the slope, m = 1/4, and the point, (1, 3):

We can substitute these values into the slope-intercept form, y = mx + b, in order to solve for the y-intercept.  

The y-coordinate (b) of the point, (0, <em>b </em>) is the <u>y-intercept </u>of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.

y = mx + b

3 = 1/4(1) + b

3 = 1/4 + b

Subtract 1/4 from both sides:

3 - 1/4 = 1/4 - 1/4 + b

11/4 = b

The y-coordinate, b, of the y-intercept is 11/4.

Therefore, the slope-intercept form is: y = 1/4x + 11/4

Answer:

I don't know if I understood the question correctly, but this is what I have...

Step-by-step explanation:

If the "x" is a variable:

(2x-3)-(1-1)=

2x-3

If th "x" is a multiplication sign:

(2x-3)-(1-1)=

-6-0=

-6

i hope this helps

Question:
Genrish500 [490]

Answer:

x=56 and the exterior angle is 116

Step-by-step explanation:

We will call the unknown angle in the triangle y.  Angle y and the angle (2x +4) form a straight line so they make 180 degrees.

y + 2x+4 =180

Solve for y by subtracting 2x+4 from each side.

y + 2x+4 - (2x+4) =180 - (2x+4)

y = 180-2x-4

y = 176-2x


The three angles of a triangle add to 180 degrees

x+ y+ 60 = 180

x+ (176-2x)+60 = 180

Combine like terms

-x +236=180

Subtract 236 from each side

-x+236-236 = 180-236

-x = -56

Multiply each side by -1

-1*-x = -56*-1

x=56

The exterior angle is 2x+4.  Substitute x=56 into the equation.

2(56)+4

112+4

116
