In a triangle, the three angles ALWAYS add up to 180°

x + (6x + 10) + (x + 2) = 180

8x + 12 = 180

8x = 168

x = 21

To calculate the measure of each angle, substitute x in:

Angle A: 21

Angle B: 6(21)+10

Angle C: 21 + 2

Do the angles add up to 180 degrees? Just add the answer for A B and C and see if the sum is 180. It should be 180, if it isn't something is wrong with the calculation.

Write an equation of the line with the given information. m. 4. A(-1.-5)

11Alexandr11 [23.1K]

Answer:

An equation of the line with the given information with

m = 4 and point A(-1, -5) is:

$y=4x-1$

Step-by-step explanation:

As the equation of a line in point-slope form is given by:

$y-y_1=m\left(y-x_1\right)$

where m is the slope.

Given:

the slope m = 4

the point A(-1, -5)

Substituting the values in the equation of a line in point-slope form

$y-y_1=m\left(x-x_1\right)$

$y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)$

$y+5=4\left(x+1\right)$

subtract 5 from both the sides

$y+5-5=4\left(x+1\right)-5$

$y=4x-1$

Therefore, an equation of the line with the given information

with m = 4 and point A(-1, -5) is:

$y=4x-1$

What does x represent in the equation is -2(bx-5)=16 if b is 3

uranmaximum [27]

Answer:

x = - 1

Step-by-step explanation:

Given

- 2(bx - 5) = 16 ← substitute b = 3

- 2(3x - 5) = 16 ( divide both sides by - 2 )

3x - 5 = - 8 ( add 5 to both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1
