Answer:
0
Step-by-step explanation:
So we have the expression:
And we want to evaluate it for x=-4 and y=8.
So, substitute:
Multiply:
Add:
Evaluate:
So, our answer is 0.
And we're done!
Answer:
Step-by-step explanation:
Solve for y to put the equation in slope-intercept form.
3x = 4y -4 . . . . . eliminate parentheses, collect terms
3x +4 = 4y . . . . . add 4
y = 3/4x +1 . . . . . divide by 4
The slope is the x-coefficient: 3/4.
The y-intercept is the constant: 1.
Answer:
Let x = the hours needed for Wanda to catch up to Hector.
Hector has already completed 18 miles. Hector travels at 12 miles per hour.
After x more hours, Hector will travel
18 + 12x miles
Wanda travels at 16 miles per hour. In x hours, she travels
16x miles
If Wanda catches up to Hector, then
16x = 18 + 12x
4x = 18
x = 4.5 hours
Answer: 4 hours, 30 minutes (or 4.5 hours)
Step-by-step explanation:
5/2 is the answer.
Have a nive day!
1/2 and 1/3 are similar because 3/6 and 2/6 are similar. They are so close but not the same.
