Answer:
A
Step-by-step explanation:If you subtract a negative number you always add remember that.
Step-by-step explanation:
Equation of a straight line
y = mx + c, m is the slope, and c the intercept
points (3,7) x = 3, y = 7, c = 1
7 = m × 3 + 1
7 = 3m + 1
3m = 7 - 1
3m = 6
m = 6/3
m = 2
Twenty-five hundreths times a number plus six tenths times a number.
Answer:3 hours
Step-by-step explanation:
Juno jogs at rate of 6 miles and bikes at rate of 14 miles covering total of 48 miles.
Akima jogs at rate of 8 miles and bikes at rate of 12 miles covering total of 44 miles.
Let jogging be represented by j
Let biking be represented by b
For Juno, 6j + 14b = 48 ......... i
For Akima, 8j + 12b = 44.......... ii
Multiply equation I by 8
Multiply equation ii by 6
48j + 112b = 384 ........... iii
48j + 72b = 264 ............. iv
Subtract equation iv from iii
48j + 112b = 384
- 48j + 72b = 264
40b = 120
b = 120/40
b = 3
Number of hours spent biking is 3 hours.
So, with rational equations, we have three different cases. If the numerator has degree m and the denominator degree n, if m>n, the rational equation has an oblique(slant) asymptote. If m=n, the asymptote is the quotient of the leading coefficient of the numerator divided by the leading coefficient of the denominator. If m<n, the rational equation has an asymptote at 0. Since m>n in this problem, we must perform polynomial division.
Since the remainder tends to 0 as it approaches infinity, we have a slant asymptote at y=3x.
