Answer:
8 * 7
Explanation:
When you count the squares along the area, you will find that the base is 8 units, and the height is 7 units. The area of a square is equal to base * height, so the correct answer is 8 * 7.
Answer:
B
Step-by-step explanation:
Use the properties of logs.
Answer:
x=-5, y=5 or (-5,5)
Step-by-step explanation:
We can do elimination with this
this means we should first multiply -5x-4y=5 by 2
this would make it -10x-8y=10
we can now subtract this from the original equation
-8x-8y=0 - (-10x-8y=10)
the ys would cancel out
so this would equal
2x=-10
x=-5
now we can plug this back into the equation to find y
-8(-5)-8y=0
40-8y=0
-8y=-40
y=5
Answer:
Solution (1, 4)
Step-by-step explanation:
x = y - 3
x + 3y = 13
Substitute x = y - 3 into x + 3y = 13
y - 3 + 3y = 13
4y - 3 = 3
4y =16
y = 4
Substitute y = 4 into x = y - 3
x = 4 - 3
x = 1
Solution (1, 4)
