Answer 1

Answer:

Answer:

$\large\boxed{y-3=-(x+4)}\nor\n\boxed{y+4=-(x-3)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

The formula of a slope:

$m=(y_2-y_1)/(x_2-x_1)$

We have two points (-4, 3) and (3, -4).

Substitute:

$m=(-4-3)/(3-(-4))=(-7)/(7)=-1$

Put the value of a slope and the coordiantes of the point (-4, 3) or (3, -4) to the equation of a line:

for (-4, 3)

$y-3=-1(x-(-4))\n\ny-3=-(x+4)$

for (3, -4)

$y-(-4)=-1(x-3)\n\ny+4=-(x-3)$

Nora started a business making bracelets. She spent $75.00 on advertising and $35.00 on supplies. She sells each bracelet for $1.50. What is the least number of bracelets Nora needs to sell to make money than she spent? Show your work.

Answers

$75 ads + $35 supplies = $110.

110 / 1.50 = 74.

Why did I divide? we take the money she spent and divide by the cost of a bracelet to figure out how many she needs to sell to get $110.

74 bracelets need to be sold.

Factor 6x2 - 33x + 15

Answers

Answer:

Step-by-step explanation:

6x² -33x + 15 =6x² -30x - 3x + (-3)*(-5)

=6x(x - 5) - 3(x - 5 )

=(x-5) (6x-3)

Answer:

3(2x - 1)(x - 5).

Step-by-step explanation:

6x2 - 33x + 15

= 3(2x^2 - 11x + 5)

= 3(2x - 1)(x - 5).

Ella conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 1 hour. What does this range say about the data? A. All the students surveyed spend exactly 1 hour surfing the Internet.
B. All the students surveyed spend an average of 1 hour surfing the Internet.
C. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
D. The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.

Answers

The answer is C.

Because we do not have any tables graphs etc., we can only use the fact that the range is 1

The definition of range is the difference between the largest amount and the smallest amount. In equation form, it should look like this: $Largest-Smallest$

Now lets move to the answer choices:

Answer A. is wrong
If everyone surfed for exactly an hour, the largest amount of time would be 1 hour and the smallest amount of time would also be 1 hour. Put this into the equation and the range would be 0 which is contradicted from the data present

Answer B. is wrong because the range is not the average, the mean is the average. We are looking for the range, not the mean so Answer B. is incorrect.

Answer C. is correct. The range is the difference between the largest and the smallest. In this answer, it tells us that the range is the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour. This follows the term of "Range" and therefore, Answer C. is correct.

Answer D. is incorrect because the range does not have anything to do with quotients.(By the way, a quotient is the result of dividing a dividend with a divisor.) The range is only obtainable with subtraction, not division, so answer D. is incorrect.
