Answer:
Step-by-step explanation:
(x + 7)(x + 4) = x(x + 4) + 7(x + 4) = x*x + x*4 + 7*x + 7*4 = x*x + 11*x + 28
2^n - 1 = 1/2(2^n)
2^1 - 1 = 2^1/2
2 - 1 = 2/2
1 = 1
Theefore, the set must have one element
Answer:
1
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -15 - -14) / ( -11 - (-10))
= (-15+14) /(-11 + 10)
= -1 / -1
= 1
Answer:
1 5/32
Step-by-step explanation:
First, find common denominators. What you do to the denominator, you must do to the numerator.
First, multiply 4 to both the numerator and denominator of the second fraction:
(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32
Next, add across:
9/32 + 28/32 = 37/32
Simplify. Turn the improper fraction into a mixed fraction:
37/32 = (32 + 5)/32 = 1 5/32
1 5/32 is your answer.
