Answer:

In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis.

Marina correctly simplified the expression (-4a^-2 b^4)/(8a^-6b^-3) assuming that a does not equal 0 and b does not equal 0. Her
Elza [17]
For this case we have the following expression:
 (-4a ^ -2 b ^ 4) / (8a ^ -6b ^ -3)
 We can rewrite the expression using properties of exponents.
 We have then:
 (-4/8) * ((a ^ (- 2 - (- 6))) (b ^ (4 - (- 3))))
 Rewriting we have:
 (-2/4) * ((a ^ (- 2 + 6)) (b ^ (4 + 3)))
 (-1/2) * ((a ^ 4) (b ^ 7))
 -1 / 2a ^ 4b ^ 7
 Answer:
 
The exponent of the variable b in Marina's solution should be 7

A remote control car races straight down the street at 26 miles per hour. Two
Pachacha [2.7K]

Answer:

It will take 4 hours for the second car to catch up with the first car.

Step-by-step explanation:

The first step to solving this problem is determining the difference in speed between the first and second car - you can see that the second car (at 52mph) is twice as fast as the first (26mph) therefore it will take half the time to cover the same distance.

As Car 1 has a 2 hour head start, it will be 52 miles ahead after 2 hours.

In the next 2 hours, Car 1 will travel 52 miles - so 104 in total after 4 hours, and car 2 will travel 104 miles, meaning that it will have caught up after 4 hours.

A)

To calculate distance per minute, divide the miles per hour by 60 (as there's 60 minutes in an hour), so:

Car 1 = 26/60 = 0.43 miles per minute

Car 2 = 52/60 = 0.867 miles per minute

To check your calculation, Car 2 should be exactly twice as far

B) The street, as far as we know, is at least 104 miles

C) See calculation at the top - the first car is 52miles from the start line when the second car starts

D) 2 cars are competing in this race

I don't really understand this stuff ;w; giving 100 points for the brainliest answer!
Nana76 [90]

Answer:

I don't really understand this stuff ;w; giving 100 points for the brainliest answer!

Q1.

Write a number sentence with at least 4 integers explaining their final score of 300. Be sure to use negative and positive integers. For example, The Super Brains answered a 250-point question correctly, a 50-point question incorrectly, a 100-point question correctly, a 200 point question incorrectly, and a 200 point question correctly. 250 + (-50) + 100 + (-200) + 200 = 300. You CANNOT copy the example as an answer.

Q2.

Write a number sentence with at least 4 integers explaining their final score of -200. Be sure to use negative and positive integers. See the first question for an example.

Q3.

Write a number sentence with at least 4 integers explaining their final score of -250. Be sure to use negative and positive integers. See the first question for an example.

Q4.

Write a number sentence with at least 4 integers explaining their final score of 0. Be sure to use negative and positive integers. See the first question for an example.

CAN SB HELP ME !! Use the image and your knowledge of the isosceles triangle to find the value of x
Anna [14]

Answer:

x = 41 degrees

Step-by-step explanation:

Since two of the sides are shown as being congruent, the base angles are the same. We are given the top angle, which is 98 degrees. All the angles of a triangle add up to 180. We can subtract 98 from 180, giving us 82, and divide that by two (since the base angles are congruent), giving us a measure of 41 degrees for each of the bottom angles of the isosceles triangle.
