Answer:oh tough one! iwould help but i cant see the pic :(
Step-by-step explanation:
Answer:
4 = the top row would be 1,2,3,4,5
the bottom row would be 14,28,42,56,70
the equation is y= 14x
5 = yes it is proportional. y=21x
6 =no it is not proportional.
7 = yes it is proportional because y= 7x
Step-by-step explanation:
Answer:
height = 2.5 units
Step-by-step explanation:
The volume of a rectangular prism is given by the product of its base area and its height. If the area of the base is 28 square units and the volume is 70 cubic units, we can find the height as follows:
Volume = base area * height
70 = 28 * height
height = 70 / 28
height = 2.5 units
The height of the rectangular prism is 2.5 units.
Answer:
The value of x = 5 and y = 2
The correct answer is last option
Step-by-step explanation:
From the figure we can see that, subtraction of two matrices.
The resultant matrix shows the corresponding terms difference.
<u>To find the value of x</u>
1/2(x + 3) - (3*(-1)) = 7
x/2 + 3/2 +3 = 7
x/2 +3/2 = 7 - 3 = 4
x + 3 = 8
x = 8 - 3 = 5
x = 5
<u>To find the value of y</u>
8/2 -3 (y +1) = -5
4 - 3(y +1)/ = -5
3(y +1) = 4 + 5 = 9
y + 1 = 9 / 3 = 3
y = 3 - 1 = 2
Therefore the value of x = 5 and y = 2
The correct answer is last option
