Answer:

A x =30

Step-by-step explanation:

(y+x) and (y-x) make a straight line so they add to 180 degrees

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

Combine like terms

y+y+x-x=180

2y=180

Divide by 2

2y/2 = 180/2

y= 90

(y+x) and 2x make a straight line so they add to 180 degrees

y+x+2x = 180

Combine like terms

y+3x = 180

Since we know y we can substitute it in

90+3x = 180

Subtract 90 from each side

90-90+3x= 180-90

3x = 90

Divide by 3

3x/3 = 90/3

x= 30

What is the slope ?????

Scilla [17]

Answer:

The slope of the line is m = 3

Step-by-step explanation:

You can easily verify that if x decreases by 2 (e. g., from -4 to -2), y increases by 6. Thus, the slope is m = rise/run = 6/2 = 3

Given the equation,D=m/v if D=6/7 and =m+3 then m=.

mamaluj [8]

Answer:

$m=18$

Step-by-step explanation:

The equation given is $D=\frac{m}{v}$

and also we have that $D=\frac{6}{7}$ , thus:

$\frac{6}{7}=\frac{m}{v}$

------------

I think the question is missing which variable is defined as $=m+3$ , so I will solve for $v=m+3$ since is the only other variable in the equation.

substituting $v=m+3$ into $\frac{6}{7}=\frac{m}{v}$ :

$\frac{6}{7}=\frac{m}{m+3}$

and we solve for m:

$(m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m$

m is equal to 18.

Answer:

3. 4a(a + 1) - 15

step-by-step explanation:

1. (x +y)² + 11 (x + y) + 30

= x + y {(x +y) + 11} + 30

2. (a - b)² - 16(a - b) + 60

= (a - b){(a - b) - 16} + 60

3. 4a² + 4a - 15) - 15

4. 2x² + 5x + 2

= x(2x + 5) + 2
