Hi there I think the answer is c hope this helps
Answer:
y = x + 8
Step-by-step explanation:
y - y1/x - x1 = y2- y1/x2 - x1
y - 8/x-0 = 9 - 8/1 - 0
y- 8/x = 1
y-8 = x
y = x + 8
Answer: No
==================================================
Work Shown:
(5 altos)/(4 sopranos) = (15 altos)/(13 sopranos)
5/4 = 15/13
13*5 = 4*15 .... cross multiply
65 = 60
The last equation is false, so the first equation is false
---------------
Alternative ratio
(5 altos)/(15 altos) = (4 sopranos)/(13 sopranos)
5/15 = 4/13
5*13 = 15*4
65 = 60
We end up with the same false equation
The given values are not in the same proportion.
The ratios are not equivalent.
------------------
Yet another way to look at it
Note the jump from 5 altos to 15 altos is "times 3"
So if we started with 4 sopranos, then we must have 4*3 = 12 sopranos as our next count.
If the second line changed "13 sopranos" to "12 sopranos", then we would have equivalent ratios.
Answer:
A) 5 in. long and 5 in. wide
Step-by-step explanation:
Given:
Volume of a rectangular prism = 75 cubic inches
Height of prism = 3 inches
Volume of a rectangular prism is given by =
where representslength of base, represents width of base and represents height of the prism.
We will check the choices given by finding the volume for the given dimensions of length and width while height remains the same and see if it matches with the given volume of the prism.
A)
Volume of prism =
B)
Volume of prism =
C)
Volume of prism =
D)
Volume of prism =
So, we see that the dimensions given in option A would give the volume of prism = 75 cubic inches.
