y=1/2x-2
Solution:First, we need to determine the slope of the line.We can pick any two points on the graph and plug them into the slope formula.I chose (0, -2) and (4, 0)Plug them into the formula:[tex]\displaystyle\frac{y2-y1}{x2-x1}[/tex][tex]\displaystyle\frac{0-(-2)}{4-0} =\frac{0+2}{4} =\frac{2}{4} =1/2[/tex]Now, the y-intercept is (0, -2) or -2.Therefore, the equation of the line isy=1/2x-2Hope it helps.
Do comment if you have any query.
[tex]\sf y = \dfrac{1}{2} x -2[/tex]
Explanation:
Take two points: (4, 0), (0, -2)Find slope:
[tex]\sf \dfrac{y2-y1}{x2-x1}[/tex]
========
[tex]\rightarrow \sf \dfrac{-2-0}{0-4}[/tex]
[tex]\rightarrow \sf \dfrac{-2}{-4}[/tex]
[tex]\rightarrow \sf \dfrac{1}{2}[/tex]
Equation:
[tex]\sf y = mx + b[/tex]
==========
[tex]\sf y = \dfrac{1}{2} x -2[/tex]

Can anyone solve this?
Answers
Answer:
324 inches squared
Step-by-step explanation:
The question is most likely asking for the surface area of the rectangular prism.
The Formula for this is:
2(wl+hl+hw)
h = 6in
w = 5in
l = 12in
Plug in the varibles:
2( 5*12 + 6*12 + 6*5)
Simplify:
2( 60 + 72 + 30) =
2(162) =
324
So the answer is 324 inches squared!
Hope this helps! :)
Answer:
The surface area of the rectangular prism is: 324
The volume of the rectangular prism is: 360
Step-by-step explanation:
Surface area is calculated with the formula:
2(wl + hl + hw)
w*l = 6*12 = 72
h*l = 5*12 = 60
h*w = 5*6 = 30
Now add up 72, 60, and 30.
72+60+30 = 162.
This leaves us with the equation:
2(162)
So, we multiply 2 and 162 to get the surface area.
2*162 = 324.
For the volume, we multiply the length, width, and height altogther.
l*w*h
So, we plug in the values, and multiply:
12*6*5 = 360
The volume is 360 in^3

HELP! 6th-grade math PLEASE HELP!
Answers
this will result in 45/4, or 11.25
now, you have to figure out how many small cubes will fit inside prism ll
we know that the side lengths of the small cubes are 1/4, and since cubes have equal side lengths, you can multiply 1/4, 1/4, and 1/4 to find the area
this will result in 1/64
divide the area of prism ll, 11.25, by the area of the small cubes, 1/64, to get 720
then, do the same thing for prism l
multiply 7/4, 3/2, and 5/4 to get 105/32
divide this by the previous 1/64 to get 210
lastly, to determine how many more small cubes can fit into prism ll, subtract 210 from 720
720-210=510
final answer: 510 cubes

Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240
1.) Complete the table above for all values of m.
2.) Which is the independent variable?
3.) Which is the dependent variable?
4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.
5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)
6.) How much money will be collected if 100 boxes of chocolate
bars are sold?
7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?
Answers
Answer:
O P=20($1.50)
They will make $3,000 if they sell 100 boxes of chocolates
Step-by-step explanation:
It is multiplication because it is $1.50 per each chocolate bar, and since there is 20 per box, we need to find the profit for the entire box
using that info, we find that each box of chocolates is 30 dollars
multiplied by 100 boxes is $3000.
