F(x) = 29x +38. F(x) is a fancy way of saying y= and you must know the basic formula y=mx+b
Answer:
- Annie- 17 hours, Brian- 3 hours
Step-by-step explanation:
Let the number of hours Annie travelled be a, and same of Brian be b
<u>Then we have</u>
<u>Substituting a in the first equation</u>
- 5b + 2 + b = 20
- 6b = 20 - 2
- 6b = 18
- b = 3
<u>Then finding a</u>
<u>So the answer is:</u>
- Annie- 17 hours, Brian- 3 hours

Thank youuuuuu
Step-by-step explanation:
Answer:
y = (2/7)x -12
Step-by-step explanation:
y = mx + b is the standard form of an equation of a straight line in which m is the slope and b is the y-intercept (the value of y when x is zero)..
<u>m</u>=(2/7) and <u>b</u> = -12
y = <u>m</u>x + <u>b</u>
y = (<u>2/7</u>)x <u>-12</u>
Answer:
Use the Pythagorean theorem for right triangles to solve this
a^2 + b^2 = c^2 where 'a' and 'b' are the legs of the triangle and 'c' is the hypotenuse
so:
8^2 + b^2 = 17^2 solve for the second leg, b
64 + b^2 = 289
b^2 = 289 - 64= 225
b = 15
