Answer:
2
Step-by-step explanation:
Substitute a = - 6 into the expression, that is
a² + 7a + 8
= (- 6)² + 7(- 6) + 8 = 36 - 42 + 8 = - 6 + 8 = 2
Heya!
2/0.5=4
You can check your work by multiplying 0.5*4.
Answer:
b = -9.
Step-by-step explanation:
The line passes through (4, 3) and (7, 12). First, we need to find the slope: the rise over the run.
(12 - 3) / (7 - 4) = 9 / 3 = 3.
Now that we have the slope, we can say that m = 3. So, we have an equation of y = 3x + b. To find b, we can use M(4, 3) and say that y = 3 and x = 4.
3 = 3 * 4 + b
b + 12 = 3
b = -9.
Hope this helps!
To do this, you first do 3^3. this is 27.
now because of the minus part, you have to do this under 1 (a reciprocal).
your answer is 1/27
