Answer:

C. x = 40

Step-by-step explanation:

1. Get the supplementary angle of ∠9: 180 - m∠9 = 180 - (4x-10)

2. The inside angles of that triangle add up to 180: 30 + 3x + 180 - (4x-10) = 180

3. Solve for x:

30 + 3x + 180 - (4x-10) = 180

30 + 3x + 180 - 4x + 10 = 180 Distribute negative to parenthesis

220 - x = 180 Combine like terms

-x = -40 Subtract 220 on both sides

x = 40 Divide both sides by -1

The first number of three consecutive even integers equals the sum of the second and third. Find the three numbers.
Arlecino [84]

The first integer (x) is equal to the consecutive even integers, x+2, x+4.

x = (x+2) + (x+4)

x = 2x + 6

x - 6 = 2x

x = -6 (First integer)


+2

-4 (Second integer)


+4

-2 (Third integer)


Integers: -6, -4, -2

Equation: x = (x+2) + (x+4)

Find the coordinates of the endpoint of the image?
ra1l [238]

Given:

The graph of a line segment.

The line segment AB translated by the following rule:

(x,y)\to (x+4,y-3)

To find:

The coordinates of the end points of the line segment A'B'.

Solution:

From the given figure, it is clear that the end points of the line segment AB are A(-2,-3) and B(4,-1).

We have,

(x,y)\to (x+4,y-3)

Using this rule, we get

A(-2,-3)\to A'(-2+4,-3-3)

A(-2,-3)\to A'(2,-6)

Similarly,

B(4,-1)\to B'(4+4,-1-3)

B(4,-1)\to B'(8,-4)

Therefore, the endpoint of the line segment A'B' are A'(2,-6) and B'(8,-4).

Find the equation of the line that is parallel to y=x-3 and contains the points (3,-2)
Degger [83]
Answer:

y = [1]x + [-5 ]

Step-by-step explanation:

the equation is : y = ax+b

the slope is a : a =1 ( same slope parrallal to the line : y= x-3 )

the line that passes through (3, -2) : -2 = (3)+b
b = -5

the equation is : y = x-5
