see what should to do buddy :
step 1-
first we have to find the gradient of the line like this:
a ( 1 , 1 )
b ( 3 , 4 )
.
step 2-
now just need one of the a or b point to put in this equation :
.
step 3-
to find the standard form of the line we have to take the y alone.
so we add the sides of the equation plus 1.
And we're done.
good luck buddy ♥️♥️♥️♥️♥️
Answer:
Step-by-step explanation:
This is good! The length of the metal is 20 inches longer than the width. But we fold up 4-inch flaps on each side, so the height of the box is 4 inches, and the length and width will each decrease by 8 inches (4 inches on each side). Since the length and width decrease by the same amount, the length will still be 20 inches longer than the width. So the equations would be:
l = w + 20
vol = l x w x h = 1716 in3
1716 = (w + 20)(w)(4)
1716 = 4w2 + 80w
4w2 + 80w - 1716 = 0
4(w2 + 20w - 429) = 0
4(w + 33)(w - 13) = 0
w + 33 = 0, so w = -33
w - 13 = 0, so w = 13
Since the width can't be negative, the width of the box is 13 and the length is 33 (13 + 20).
But remember, the length and width of the piece of metal are each 8 inches longer than the box, so it was 41 inches by 21 inches.
The domain of a relation is all the x values of the coordinates for that relation
D. 16
Cross multiply, to cancel the denominator; so if you multiple by 6 on one side, to cancel the division of 6 - you must also multiply the other side by 6 & vice versa.
You get:
8(x-4) = 6x
Expand bracket to get:
8x - 32
Now solve for x :
8x - 32 = 6x
- 8x
- 32. = - 2x
÷ - 2
16 = x
Or
8x - 32 = 6x
+ 32
8x. = 6x + 32
- 6x
2x. = 32
÷2
x =16
Check:
16 - 4 = 12, then ÷ 6 is 2
16/8 = 2
Hope this helps!
Answer:
1/12.
Step-by-step explanation:
The sum can be 2 or 3.
Possible ways to get this are (1, 1), (1, 2) and (2,1).
That is 3 ways out of a total of 36 possible outcomes.
So The answer is 3/36 = 1/12.
