Answer:
13.25 ft
Step-by-step explanation:
Let w represent the width of the window. Then w-5 represents the length, and the perimeter is ...
P = 2(L+W)
43 = 2((w-5) +w) = 4w -10
53/4 = w = 13.25 . . . feet
The width of the window is 13.25 ft.
Answer:
∠1 and∠3 = Supplementary Angles
∠4and∠5 = Complementary Angles
∠5and∠1 = Adjacent Angles
∠2and∠3 = Supplementary Angles
Slope intercept form is: y=mx+b
For the other line to be parallel they must have the same slope so:
y=5x+b, using the point (4,5) we can solve for the y-intercept, or "b"
5=5(4)+b
5=20+b
b=-15 so the line is:
y=5x-15
Answer:
the answer is 5ft wide
Step-by-step explanation:
Hope this helps!
4x - 2y ≤ 6 <em>subtract 4x from both sides</em>
-2y ≤ -4x + 6 <em>change the signs</em>
2y ≥ 4x - 6 <em>divide both sides by 2</em>
<h3>y ≥ 2x - 3</h3>
y = 2x - 3 - it's a linear function. We need only two points to plot the graph.
Choose any two values of x and calculate the values of y:
for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)
for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)
