i need some help im confused.....

Answer:

x=20

Step-by-step explanation:

the sum of the angles of a triangle is always 180, so we can set up an equation using these angles.

31+90+3x-1=180

collect like terms: 120+3x=180

subtract 120 from both sides

3x=60

divide both sides by 3

x=20

Answer:

y=2x+4   I HOPE THIS HELPS YA

Step-by-step explanation:

m=2

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope 2

and a given point (−1,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=y2−y1x2−x1

.

y−(2)=2⋅(x−(−1))

Simplify the equation and keep it in point-slope form.

y−2=2⋅(x+1)

Solve for y

y=2x+4.

Answer:

4x + 3y = 1

Step-by-step explanation:

(1, -1)

3x - 4y = 20 ---> 4y = 3x - 20 ---> y = 3/4 x  - 5

so slope is 3/4

and perpendicular slope is m * 3/4 = -1

m = -4/3

line equation is y - y1 = m (x - x1)

y - (-1) = -4/3 ( x  - 1)

y + 1 = -4/3 (x - 1)

3y + 3 = -4x + 4

4x + 3y = 1

Step-by-step explanation:

The y intercept is the rate of change or the value of zero

The reason that this rivalry has formed is that a common goal has been set for a greater number of groups than the one that could obtain a positive result, generating a competition between these that implies a constant desire to overcome the other groups.

Thus, the existence of these common objectives makes competition take place, and generates tensions between the groups.

Answer:

a. 3 and 8

b. 17

c. 3x^2, 8x, and 17

Step-by-step explanation:

a. The coefficients of an equation are the numbers that come before the variables, in this case x. We can see there is a 3 multiplying x^2 and an 8 multiplying x, therefore the coefficients would be 3 and 8.

b. The constants are the numerical terms(ones without x). This would be 17.

c. Terms are the products of numbers and/or variables separated by addition or subtraction. These would be 3x^2, 8x, and 17.

Answer:

x = -10

Step-by-step explanation:

Essentially, the function notation, "g(x)" is the same as y.  

Given g(x) = 2(x - 5), we could determine x for g(x) = - 30 by substituting -30 as the value of g(x) into the function:

g(x) = 2(x - 5)

-30 = 2(x - 5)

Distribute 2 into the parenthesis on the right-hand side of the equation:

-30 = 2x - 10

Next, add 10 to both sides of the equation:

-30 + 10 = 2x - 10 + 10

-20 = 2x

Finally, divide both sides by 2 to solve for x:

[tex]\LARGE\mathsf{\frac{-20}{\:2}\:=\:\frac{2x}{2}}[/tex]

Verify whether we have the correct value for x by substituting x = -10 into the given function:

g(x) = 2(x - 5)

-30 = 2(-10 - 5)

-30 = -20 - 10

-30 = -30 (True statement).

Therefore, the value of x = -10.

Answer:

y = -2x + 3

Step-by-step explanation:

Parallel lines are lines with the same slope (m), but a different y - intercept (b).

The basic equation of a line is y = mx + b, where m represents slope, and b represents the y - intercept

First solve for the parallel slope of -2

Parallel slope to -2 = -2

Next, input the x and y values given to you by the point to the equation

y = -2x + b

We will input the -1 and 5 for x and y in the equation y = -2x + b

5 = -2(-1) + b

5 = 2 + b

b = 3

The line is y = -2x + 3

-Chetan K

Answer:

b) 1 / 4

c) -3

Step-by-step explanation:

b) line passing through points (0,-1) (4,0)

slope = (y2 - y1) / (x2 - x1)

= (0 - (-1) ) / (4 - 0)

= 1 / 4

c) line passing through points (-1,2) (0, -1)

slope = (y2 - y1) / (x2 - x1)

= (-1 - 2) / (0 - (-1) )

= -3 / 1

= -3

Answer:

the difference between -4 and 1 is 3. distance is always positive.

8 less than 2, is -6. (I'm pretty sure)

13 more than -1 should be 12.

to get 2 add 8. -6+8 is 2.

to get -3 subtract 10 from 7.
