Answer:
13 degrees, I think.
Step-by-step explanation:
On a number line -5 is to the left, so you'd count over to the right until you got to 7 which would result into your answer being 13. (not 100% sure)

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.

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)

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}

Brian is solving an equation where both sides are quadratic expressions. He sets the expressions equal to y. Then he graphs the system finding that the two graphs share a common vertex, but one graph opens upward and the other opens downward. How should Brian interpret this outcome?Then he graphs the system finding that the two graphs share a common vertex, but one graph opens upward and the other opens downward.

Brian interprets this outcome because There is exactly one intersection point.
What is a Quadratic equation?ax2+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Given, Both sides of the problem Brian is solving have quadratic expressions. He sets y as the value for the expressions. The system is then graphed, and he discovers that the two graphs have a similar vertex but that they have opposite opening directions.
The parabola expands upward if the leading coefficient is larger than zero and downward if the leading coefficient is less than zero.
A route that starts and finishes at the same vertex is called a circuit. A cycle is a circuit that doesn't repeat its vertices. If a path connects any two of a graph's vertices, the graph is said to be linked.
Therefore, Brian interprets this outcome because There is exactly one intersection point.

Joe's climbing rate is not constant
3 × 2 = 6
8 × 1.5 = 12
12 × 1.1666666667 = 14
Time when climber reaches 30ft is unknown because climbing rate is not constant
Zas's climbing rate is 2.5
2 × 2.5 = 5
4 × 2.5 = 10
12 × 2.5 = 30
At 12 seconds, Zas reaches 30 feet.
Stephen's climbing rate is 4
2 × 4 = 8
4 × 4 = 16
6 × 4 = 24
30 ÷ 4 = 7.5
7.5 × 4 = 30
At 7.5 seconds, Stephen reaches 30 feet.
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.
