Answer:
23.6
Step-by-step explanation:
<u><em>Finding AC:</em></u>
Cos 61 = 
0.48 × 10 = Adjacent
AC = 4.8
<u><em>Now, CB:</em></u>
Cos 29 =
0.87 × 10 = CB
CB = 8.8
<u><em>The perimeter:</em></u>
=> 10+4.8+8.8
=> 23.6
Answer: -6 = x
Step-by-step explanation: Start by distributing through the parentheses
on each side of the equation to get 5x - 40 = 7x - 28.
Now move your x's to the right and
numbers to the right and you get -12 = 2x.
Divide both sides by 2 and -6 = x
Answer:
g=8
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Not a function of x
Step-by-step explanation:
A vertical line intersects the graph twice, which immediately tells us that y is not a function of x here. If y were a function, the vertical line would intersect the graph in only one place.
Step-by-step explanation:
Point B(2, 8) reflect to x-axis
It means the x value won't change, the only thing that will change is the y value.
According to it, we can know that B' is (2, -8)
(2, -8) → (-8, 2+4) = (-8, 6) = B''
