3x - 12 = -15
Add 12 on both sides.
-12 + 12 = 0
-15 + 12 = -3
The equation is now 3x = -3.
Divide both sides by 3 to isolate the variable.
3x / 3 = x
-3 / 3 = -1
So, x = -1.
Answer:
110 in²
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h . . . . . . where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.
In your problem, b1 and b2 are 13 in and 9 in, and h is 10 in. Putting these values into the formula, we find the area to be ...
A = (1/2)(13 in + 9 in)(10 in) = 110 in²
The area of the trapezoid is 110 square inches.
_____
First, we identify the appropriate formula to use for the geometry shown in the diagram.
Next, we determine from the diagram the values to use in the formula.
Last, we evaluate the formula and make a summary statement of results.
There is only 1 ace of spades because theres only 4 aces 1 hearts 1 clubs 1 diamonds and 1 spades.
I hope this helps :)
Answer: -16
Explanation: Since you are subtracting a negative number from -17, you are actually just adding that number to it, and -17 + 1 is -16
Answer:
Not a function
Step-by-step explanation:
There are two points in the set that have the same x-value or "input": (6,4) and (6,-4). This fails the vertical line test which means that one input will give two potential outputs. This cannot make a function.
