Answer:

Angle B is 41 degrees

Step-by-step explanation:

1) find the supplement of the 113 degree angle; it is 180-113, or 67, degrees.

2) recognizing that the sum of the interior angles of a triangle is 180 degrees, add up 67 and 72 degrees, obtaining 139 degrees, and subtract this sum from 180 degrees:

180 degrees - 139 degrees = 41 degrees (answer)

The steps are outlined above; the end result is that <B is 41 degrees.

F(x) = x + 6 , find the ordered pair when x = -2.

ss7ja [257]

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

Answer: $\textsf{Option A, (-2, 4)}$

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

Given: $\textsf{f(x) = x + 6}$

Find: $\textsf{f(-2)}$

Solution: We need to plug in the value -2 into every variable x that we have in the expression and simplify to get the solution.

Plug in the values

$\textsf{f(x) = x + 6}$

$\textsf{f(-2) = -2 + 6}$

Simplify

$\textsf{f(-2) = -2 + 6}$

$\textsf{f(-2) = 4}$

Therefore, the ordered pair that would match would have a x-coordinate of -2 and a y-coordinate of 4 producing (-2, 4) which matches option A.

Graph the line with the slope -3/4 passing through the point (4,-1)

-Dominant- [34]

Answer:

Step-by-step explanation:

Plot the point (4, -1) in the 4th Quadrant.

The slope (-3/4) tells us what to do next:

With your pencil point initially on (4, -1), move it 4 units to the right, to (8, -1).

With your point initially on (8, -10, move it down 3 units, to (8, -4). Plot (darken) (8, -4).

Draw a line through (4, -1) AND (8, -4)

1. 4x = 7(x - 3) 1.Given

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

2. 4x = 7x - 21 2.Distributive property

4x - 7x = 7x - 7x - 21

3. -3x = -21 3.Subtraction property of equality

-3x : (-3) = -21 : (-3)

4. x = 7 4.Division property of equality
