Answer:

opposite angles are equal, and since, the figure is a rectangle, all its sides measure 90 degrees. Which means, in the side with 47, the angle will be 90 degrees if the other angle is mentioned.( 90-47=43), and we know that opposite angles are equal, and on a line that divides the angles, 43 is equal to 6x+19. so, 6x+19=43,

6x=43-19=24

x=24/6=4

in the same way, the angle 47 mentioned in the figure is equal to the angle beside 6x+19

Answer:

x=4

Step-by-step explanation:

ABCD is a rectangle, so AD and BC are parallel. Thus, The angle complementary to 6x+19 is 47.

6x+19+47=90

6x+66=90

6x=24

x=4

slope intercept:

y=3/4x-7

point slope form:

I used the y intercept (0,-7) as a point to plug into point slope form.

y+7=3/4(x-0)

One of the tables shows a proportional relationship.

beks73 [17]

Answer:

See attached

Step-by-step explanation:

The graph of a proportional linear relationship is a line that passes through the origin (0, 0).

From inspection of the given tables, the linear equations for each table of points is:

Table 1: y = x + 1
Table 2: y = x/2
Table 3: y = x + 2
Table 4: y = 2x + 1

The only equation for which y = 0 when x = 0 is y = x/2 → Table 2.

Given points from Table 2:

(2, 1)
(4, 2)
(6, 3)
(8, 4)

To graph the line, plot the given points and draw a line through them (see attached).

Help Please I Don’t Understand

Nat2105 [25]

Answer: -4x+5>-5=x>2.5

-25>-5(x+2.5)=x<2.5

Step-by-step explanation:

-4x+5>-5 -25>-5(x+2.5)

-5 -5 -25>-5x-12.5

-4x>-10 +12.5 +12.5

/-4 /-4 -12.5>-5x

x>2.5 /-5 /-5

2.5>x

x<2.5
