Answer:
ABC is isosceles
Step-by-step explanation:
This is a simple equation:)
We have to isolate "n" to be alone.
-21 = n - 8
First add 8 to both sides.
-21 = n - 8
+8 = + 8 it cancels out on the right side of the equal side and you solve on the left side
soooo
-21 + 8 = -13
-13 = n
Finally our answer is
-13 = n
When in doubt, eat a pineapple:)
Answer:
x=1
Explain:
y=2x^2−4x+1
dy/dx=4x-4
The line of symmetry will be where the curve turns (due to the nature of the
x^2 graph.
This is also when the gradient of the curve is 0.
Therefore, let
dy/dx=0
This forms an equation such that:
4x−4=0
solve for x,
x=1
and line of symmetry falls on the line
x=1
Answer:
Step-by-step explanation:
Answer:
The sum of 5x and 2xis at least 14 as an inequality is: 5x +2x < 14
The product of x and y is less than 4 as an inequality is: x * y < 4
