Answer:
x = - 18
Step-by-step explanation:
Given
- 7 + 
= - 13 ( add 7 to both sides )
= - 6 ( multiply both sides by 3 to clear the fraction )
x = - 18
Answer:
Step-by-step explanation:
divide y by x
in a table and coordinate pair, which is something like (0,4), x always comes first. So, in this table x is the time in seconds and y is the distance in meters. 120/4=30 meters per second. For the second part of the table, since we know what the slope is, or the constant rate of change, 30, we can multiply 30 by 25 which is 750. You can also use the equation y=mx, m is the slope, and x is a point on the coordinate pair. For example, in the second table, y=30(25). For the last part of the table, you can use the same equation. 270=30x. We try to get x alone so we do, 270 divided by 30 which is 9. So a cheetah runs at 270 meters per 9 seconds.
The inequality becomes :
350B+525F≤4500
Explanation:
Let the number of basil plants be represented by = B
Let the number of fennel plants be represented by = F
As each basil plant needs 350 ml of water, so B basil plants will need 350*B = 350B ml of water
Similarly, each fennel plant needs 525 ml of water so F fennel plants will need 525*F = 525F ml of water.
And both the plants need to be watered with a maximum of 4500 ml of water.
So inequality becomes: 350B+525F≤4500
It should be k= 4 or -1/3
The formula for area of a circle is (pi)*radius^2
Radius is half of diameter so the radius is 2.
2 squared is 4, then multiply by pi to get an answer of 4(pi) or 12.56.
