Answer:
The Acceleration, In Centimeters Per Second Per Second, Of A Projectile Is Modeled By A (T) = 21" - 156 + 36, Where T Is Measured in seconds
Answer:
Very similar to solving an equation.
Step-by-step explanation:
You have to use the properties of equality to "undo" each number and isolate the letter to one side.
How ever, if you are multiplying or dividing by a negative number, then the inequality must be reversed.

Answer:
Step-by-step explanation:
the sum of angles of triangle=180 degrees
one angle=90 degrees
180-90=90 degrees is the measure of the other two angles
since the two angles are congruent or equal
90/2=45 degrees
the measure of the 2 angles =45 degrees each
6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
