Answer:
Step-by-step explanation:
First, plug in both answers into the slope formula. You should get 1/2. Then you have to find the y-intercept. This is -1. The formula is y=1/2x -1
Answer:
y=7
Step-by-step explanation:
Slope: 7-7/4-0=0
Point: (0,7)
pt/slope form:
y-7=(0)(x-0)
y=7
The long, straightforward, brute-force way to slog through the problem:
The prism is 12cm x 6cm x 9cm.
Volume of the prism = (12 x 6 x 9) = 648 cm³
Volume of each little cube = (1.5 x 1.5 x 1.5) = 3/375 cm³
Number of little cubes that fit into the prism = (648 cm³) / (3.375 cm³) = <em>
192 of them</em>
=============================================
The elegant but almost equally long way to master the problem:
The prism is 12cm x 6cm x 9cm.
If each dimension of your measuring cubie is 1.5cm,
then the prism measures
(8 cubie lengths) x (4 cubie widths) x (6 cubie heights) .
Its volume is (8 x 4 x 6) = <em>192 measuring cubies</em>.
Difference between x and y is 25
lets say x is bigger
x-y=25
smaller is 1/6 of larger
y=x/6
sub x/6 for y in other equation
x-(x/6)=25
times both sides by 6
6x-x=150
5x=150
divide both sides by 5
x=30
y=x/6
y=30/6
y=5
the smaller number is 5
The answer would be $42.4. $50 minus $10 is $40. Multiply that by 106% because of tax, and you get $42.4.
Hope this helped! :)
