Answer:
r=8
Step-by-step explanation:
45=6r-3
48=6r
r=8
The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression.
a²b(7 + 10b +14b²)
None of the above..........
Answer:
3. 63°
4. x = 13
Step-by-step explanation:
3. The exterior angle is equal to the sum of the opposite interior angles.
118° = (4x +7)° + (6x -9)°
120 = 10x . . . . . . . . . divide by °, add 2
12 = x
m∠K = (6x -9)° = (6·12 -9)°
m∠K = 63°
__
4. Corresponding angles are congruent, and the sum of angles in a triangle is 180°.
74° + (5x)° + (3x+2)° = 180°
8x = 104 . . . . . . . . . . . . . . . divide by °, subtract 76
x = 13 . . . . . . . . . . . . . . . . . .divide by 8
Answer:
f(2) = -5
Step-by-step explanation:
f(2) means that x = 2.
We are trying to find the y-value when x = 2.
When x = 2, we see from the graph that our y-values is equal to -5.
Therefore, f(2) = -5
