The domain is -1, 0, 1, 2, 3, 4. Hope this helps.
Answer:
Z=8 is the answer
Step-by-step explanation:
first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8
2x-y=0 Y=x-1 2x-x-1=0 x-1=0
A. 38
Let X = seventh graders
6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.
2X + X = 57
3X = 57
X = 57 / 3
X = 19
IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.
Add both numbers to check: 19 + 38 = 57.
Answer:
100-25pi m
Step-by-step explanation:
Let us subtract the circles area from the square
<em>First, let us find the area of the square:</em>
Base x height =
10m x 10m = 100m
<em>Now, the circle:</em>
pi x radius ^2 =
pi x (10/2)^2 =
pi x 5^2=
25 pi
Therefore, the shaded area is 100-25pi m. You can also simplify it further by plugging in the 3.14... value into pi.
