F(x) = x - 7
x = -2
f(-2) = -2 - 7
f(-2) = -9
Answer:
3/2
Step-by-step explanation:
you basically just simplify the exponents first, and then simplify from there.
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(2.7,5.1)...x1 = 2.7 and y1 = 5.1
(3,4.7)...x2 = 3, and y2 = 4.7
now we sub
d = sqrt (3 - 27/10)^2 + (47/10 - 51/10)^2
d = sqrt (3/10^2) + (-2/5^2)
d = sqrt (9/100 + 4/25)
d = sqrt 1/4
d = 1/2 or 0.5 <==
Use proportions:
66.4/360 = x/15.8π
The degree of the arc over the total degrees of the circle is equal to the length of the arc(x) over the circumference of the circle
x = 9.2
Assuming none of the factors is zero, if an odd number of the factors of a multiplication problem have negative signs, then the product will be negative. Otherwise, the product is positive.
Assuming the dividend of a division problem is non-zero, the quotient wil be negative if the signs of the dividend and divisor are differnt. Otherwise the quotient is positive.
In short, if a multiplication or division problem involves an odd number of minus signs, the result will be negative. Otherwise, the result is positive.
