Answer:
The first answer one is true
Answer:
7. y
=
−
1
/2
x + 4
8. y= (0,4)
Step-by-step explanation:
7. the slope is -1/2 and the y intercept is 4
8. so basically, the y intercept is when y is zero, which makes this one (0,4)
HOPE THIS HELPS HAVE A GREAT DAY!!! IM procrastinating chem doing this lolz
If you don’t know what a number is, you should substitute it for x and make an equation with the information you have been given. This gives:
(x + 8) x 2 = x - 11
Then, solve:
2x + 16 = x - 11
2x = x -27
x = -27
This can then be checked by using the number in the original text.
-27 + 8 = -19
-19 x 2 = -38
-38 is 11 less than -27.
Hope this helps :)
Answer:
46,000,000 (46 million)
Step-by-step explanation:
If the number to the right (in this case the hundred thousands place) is 5 or greater then you round up.
If it was lower than 5 you would round down.
As the number in the hundred thousands place is 6, this means we can round up.
Answer:
RC = 40
Step-by-step explanation:
Note that the circumcentre is equally distant from the triangle's 3 vertices.
That is : PC = RC = QC
Equate any pair and solve for x
Using RC = PC, then
5x - 15 = 3x + 7 ( subtract 3x from both sides )
2x - 15 = 7 ( add 15 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Hence
RC = (5 × 11) - 15 = 55 - 15 = 40 units
