What is an equation of a line that passes through the points (3, -5) and (-6,-8)?
Answer:
y=1/3 x -6, y equals one third x minus 6
Step-by-step explanation:
The equation will look like -5/3 - -8/-6 since we're finding the slope. That equals 3/9 or 1/3, the slope is 1/3. But since we also need to find the y-intercept, we need to solve another equation, y-y1=m(x-x1). Now we just need to put in the values. y-(-5)=1/3(x-3) this becomes y+5=1/3 x - 1, subtract 5 to isolate y, y=1/3 x -6.
Write an equation of the line that is perpendicular to line y =(1/2) x – 7 and passes the point (0, – 3).
Answer:
y = -2x -3
Step-by-step explanation:
If a line is perpendicular to another line, it means that the gradient of the new line (one that is perpendicular) is going to be the negative reciprocal of the old one.
Reciprocal means that it is flipped. So 1/2 would be 2 and 5 would be 1/5
A bin contains 26 markers. Four students each choose the same number of markers. If they choose as many markers as possible, how many markers are left in the bin?
Your're Answer:
there would be 13 markers for each student and 26 divided by 13 would be 2 so there is two markers left in the bin.

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.
According to a study, for every 50C increase in rental price, the average business can expect to lose 4 rentals a day.
Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50 price increases.
b(x)= x + x+ [
Answer:
b(x) = (3+0.5x) (38-4x)
Step-by-step explanation:
Let the generated revenue per day be b(x)
Let x be the number for every 50cents($0.5) price increase
Formula to be used to generate the revenue generated is expressed using the formula:
b(x) = Price × Quantity
Next is to derive the price and quantity function in terms of x.
For the price:
If he currently charges $3 per book
Let derive the price function for the model and x number of price increase for every 50 cents, then
Price = ($0.5 of x)+$3
Price = $3+$0.5x
Price = $(3+0.5x)
For the quantity:
Number of books rent out per day = 38
If for every 50cents increase in rental price x, the average business can expect to lose 4 rentals a day, then the total lost per quantity = 4x
Quantity per time = Number of books rent out daily - loss on each book
Quantity = $(38-4x)
Next is to substitute the price and quantity function into the revenue formula above:
Revenue = Price × Quantity
Revenue = (3+0.5x)(38-4x)
Hence the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50 price increases is b(x) = (3+0.5x)(38-4x)
Calculate the distance travelled by a bus in 2 hours which moves with the velocity of 22 meter per second
Answer:
158,400 m. or 158.4 km.Step-by-step explanation:
distance = velocity x time
where: time = 2 hrs. x 3600 sec / 1 hr
= 7200 secs
velocity = 22 m/s
plugin values into the formula:
distance = 22 m/s x 7200 sec.
= 158,400 m. or 158.4 km

How many real roots are there for the equation, x^2+4x-1=0 I think the answer is two real roots
Answer:
2 real roots
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the nature of the roots are found using the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then 2 complex roots
x² + 4x - 1 = 0 ← is in standard form
with a = 1, b = 4, c = - 1, then
b² - 4ac = 4² - (4 × 1 × - 1 ) = 16 + 4 = 20
Since b² - 4ac > 0 then the equation has 2 real and distinct roots

Step-by-step explanation:
Kim bought 12 boxes of drinks
He paid $15 for each box.
There were 12 drinks in each box.
Kim sold 3/4 of the drinks for $1.50 each.
He sold all of the other drinks at a reduced price.
He made an overall profit of 15%.
Work out how much Kim sold each reduced price drink for.
Answer:
The amount Kim sold each reduced price drink is $1.25 each
Step-by-step explanation:
The number of boxes of drinks Kim bought = 12 boxes
The amount Kim paid for each box = $15
The number of drinks in each box = 12 drinks
The amount Kim sild 3/4 of the drinks = $1.50 each
The amount Kim sold the remaining drinks = At a reduced rate
The amount of profit Kim made = 15%
Therefore, we have;
The total amount Kim bought the whole drinks = 12 × $15 = $180
The total number of drinks = 12 × 12 = 144 drinks
3/4 of the drinks = 3/4×144 = 108 drinks
The amount Kim sold the 108 drinks = 108 × $1.5 = $162
The amount of profit Kim made = 15%
Therefore;
(((The total amount Kim sold the whole drinks) - (The total amount Kim bought the whole drinks))/(The total amount Kim bought the whole drinks)) × 100 = Percentage profit
(((The total amount Kim sold the whole drinks) - ($180))/($180)) × 100 = 15%
The total amount Kim sold the whole drinks = 0.15×$180 + $180 = $207
The total number of the remainder of the drinks = 144 - 108 = 36 drinks
The amount Kim sold the remainder of the drinks = $207 - $162 = $45
The amount Kim sold each of the remainder of the drinks at reduced price = $45/36 = $1.25
Therefore, the amount Kim sold each reduced price drink = $1.25 each.

C={0,1,3,5,7},D={1,2,4,6,7}} intersection in them??
Answer:
the answer isC n D= {1,7}
Answer:
The intersection in them is {1, 7}
Step-by-step explanation:
Let us revise some definition in the operation of sets of numbers
The intersection of two sets of numbers is the set of all elements belong to both setsThe union of two sets of numbers is the set of all elements belong to one of the two sets (without repetition)→ Ex: set A = {1, 2, 3, 5, 6} and set B = {4, 5}, then
A ∩ B = {5} ⇒ ∩ is the symbole of intersection A ∪ B = {1, 2, 3, 4, 5, 6} ⇒ ∪ is the symbole of unionLet us solve the problem
∵ C = {0, 1, 3, 5, 7} , D = {1, 2, 4, 6, 7}
→ The common elements in the two sets are 1 and 7
∴ C ∩ D = {1, 7}
∴ The intersection in them is {1, 7}
