∠1 and ∠3 are complementary,
∠1 = ∠2,
so
∠2 and ∠3 are complementary.
Hello! First I would just look at the numbers without the zeros. So 28/7. This equals 4. Next cross out the same number of zeros on each side of the equation. In this instance, the 7 has one zero and the 28 has three so you can cross out one zero on each side. This leaves you with two zeros left over to add to the end of the 4. So you end up with 400.
I hope this helps!
Answer:
x = - 2
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis.
Thus a perpendicular line will be vertical and parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 1) with x- coordinate - 2, thus
x = - 2 ← equation of perpendicular line
first equation equivalent to
4x+8y=28
substract with second equation
-2x=22
divide with -2
x=-11
substitute to first equation
8y=28-4(-11)
8y=72
divide with 8
y=9
so the solution is (-11,9)
The function tule for the table is
y = 2x
If you line the table vertically, you can see the x value is +1 because how does 0 go to 1, you add one to it.
With the y variable, you can view its being multiplied by 2 since 5x2 = 10 , 10x2 = 20 and so on.
Therefore the function rule is y=2x
