Answer:
(-2, -1)
Step-by-step explanation:
first you must reorganize the equations so that one of them has x or y equaling to something
x - y = -1 --> x = y - 1
then substitute that in for x
3(y - 1) - 5y = -1
and solve for y
3y - 3 - 5y = -1
-2y = 2
y is -1
then plug it back in to an equation to find x
x + 1 = -1
x is -2
Answer:
Option c is correct
Step-by-step explanation:
Sampling error occurs when you are biased at sample selection when make some individuals less likely to be included in the data thereby miss representing the entire population.
<h3>#a</h3>
∠XBC= 55°
[ By corresponding angles]
- Corresponding angle are the angles which hold sane relative position as another angle but somewhere else on the figure.
<h3>#b</h3>
∵ XB and XC are equal, ∠XBC=∠BCX
<h3>Now, With angle sum property of triangle: </h3>
Answer:
L = w + 5
P = 2(L+w) = 42
L + w = 21
w+5 + w = 21
2w + 5 = 21
2w = 16
w = 8 ft
L = w+5 = 13 ft.
Rectangle is 13 ft by 8 ft
Area = 13(8) = 104 ft2
Check: P = 2(L+w) = 2(13+8) = 2(21) = 42 ft
Answer:
