Step-by-step explanation:
6n-10=50
6n=60
n=10
rlu=6n-10
=6×10-10
=60-10
50
The area is 3/8 yd².
Area = length x width
Given:
length = 3/4 yard
width = 1/2 yard
Area = 3/4 yd * 1/2 yd
Area = 3*1/4*2
Area = 3/8 yd²
In multiplying fractions, multiply the numerators, then, multiply the denominators. lastly, simplify the fraction. 3/8 yd² is already in its simplest form.
-5x - 6y = -21
5x - y =. 84
-7y = 63
y= -9
-5x = -21 - 54
-5x = -75
x = 15
Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2) and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)
Answer:
1.Yes
2.Yes
3.No
4.No
5.Yes
Step-by-step explanation:
Just plug in the values of x and y for each set of coordinates.
Example from the first one
4x=y
4(5)=20
20=20 True
make sure all are valid by plugging in the next set of coordinates
4(6)=24
24=24 True
4(7)=28
28=28 True
and so forth with each equation plug in the coordinates
