Answer:
-3 -2
-2 0
-1 6
3 10
4 12
Step-by-step explanation:
f(x)=2x+4
Let x = -3 f(-3) = 2*-3 +4 = -6+4 = -2
Let x = -2 f(-2) = 2*-2 +4 = -4+4 = 0
Let x = -1 f(1) = 2*1 +4 = 1+4 = 6
Let x = 3 f(3) = 2*3 +4 = 6+4 = 10
Let x = 4 f(4) = 2*4 +4 = 8+4 = 12
Answer:
- 116
Step-by-step explanation:
Given
28 - ( 
)²
= 28 - (12)²
= 28 - 144
= - 116
Answer:
x = 1/4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = 10
Explanation:
A square is a quadrilateral in which all sides are equal.
We are given that:
ABCD is a square
AB = 5x - 10
BC = 2x + 20
Since we're talking about a square, therefore:
AB = BC
5x - 10 = 2x + 20
5x - 2x = 20 + 10
3x = 30
x = 30/3
x = 10
Now, we can check our solution:
AB = 5(10) - 10 = 40 units
BC = 2(10) + 20 = 40 units
We can see that both sides are equal
Hope this helps :)
