Answer:
∠abc=34°
∠dbc= 44°
Step-by-step explanation:
(5x+4)+(5x-6)=78
10x-2=78
10x=78+2
10x=80
x=8
put x in each equation
∠abc= 5x8-6
40-6
34°
78-34= ∠dbc
∠dbc= 44°
Area of rectangles = width * length.
So x*12 = 12x = area of first rectangle
So 16*(x-2) = 16x -32 = area of second rectangle
The question states to make them equal, so:
first rectangle = second rectangle
12x = 16x -32
Solve for x
-4x = -32
4x = 32
x = 8
<h3><u>The y-intercept is -14.</u></h3><h3><u>The x-intercept is -1.56</u></h3>
y = - 9x - 14
We already know the y-intercept of the line is going to be -14. We can tell this because the equation is written in slope-intercept form.
To find the x-intercept, we need to set the value of y equal to 0.
0 = -9x - 14
Add 14 to both sides.
14 = -9x
Divide both sides by -9.
x = 14/-9 = -1.56
