Answer:
(0, -26)
Step-by-step explanation:
We can use the 2-point form of the equation for a line to write its equation:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1 -(-8))/(36 -24)(x -24) -8
y = 9/12(x -24) -8
y = 3/4x -26
Comparing this to slope-intercept form:
y = mx + b
we see that the y-intercept, b, is -26.
The y-intercept of the line is (0, -26).
Answer: yes they are equivalent
Step-by-step explanation:
No matter how the number is placed in the equation if it is the same numbers they are equivalent
The answer is B. 2.25 degrees Fahrenheit because if you subtract 3/4 from 3, you shall get 2.25.
Answer:
See below.
Step-by-step explanation:
When Brian passes Alex they both have travelled the same distance.
Call this distance d.
Let the speed that Brian passes = x miles/hour.
Distance = speed * time so:
For Alex:
d = (x - 5) * 1.5 ( Alex cycles for 1 + 30 minutes = 1.5 hours)
For Brian:
d = x * 1
So substituting d = x in Alex's equation:
x = 1.5(x - 5)
x = 1.5x - 7.5
7.5 = 0.5x
7/5 / 0.5 = x
15 = x.
ANSWER:
Brian's speed is 15 miles/hour.
Alex's speed is 15 - 5 = 10 miles/hour.
Collect like terms
15 + 3 + 9x + 7x = y
18 + 16x = y
Recall
b + mx = y
m = 16
b = 18
