Answer:
x=1 x = -1
Step-by-step explanation:
2|5x|= 10
Divide each side by 2
2/2|5x|= 10/2
|5x|= 5
Absolute values have 2 solutions, one positive and one negative
5x = 5 5x = -5
Divide each side by 5
5x/5 = 5/5 5x/5 = -5/5
x = 1 x = -1
Answer:
V= 100°
X=50°
Y=40°
Z=40°
Step-by-step explanation:
All angles in a triangle add up to 180°, and you know that the corners are 90° because it is a rectangle.
Answer:
y= -2x
Step-by-step explanation:
To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.
5x-10y=-12
-10y=-5x-12
y=1/2 x + 1.2
The slope is 1/2 and the slope of the new line will be -2 because the negative reciprocal create a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-8)=-2(x--4)
y-8=-2(x+4)
y-8=-2x -8
y= -2x +0
Answer:
m = 1, y = 1x + 10
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)
m =
=
=
= 1
Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1x + 10.
The lengths of th pieces are 10 foot and 4 foot.
