Answer:
A. the slope is -2
the y-intercept is (0,1)
Step-by-step explanation:
If y=mx+b, m is the slope and b is the y-intercept.
If we replace the variables with y=-2x+1, we can see -2 is the slope and the y-intercept is (0,1).
Roberto is 3 years older than Carolyn. In 7 years the sum of their ages will be 81. How old is Roberto now?
Answer: 35
the age of Roberto is x (x > 3)(x ∈ N)
because Roberto is 3 years older than Carolyn => the age of Carolyn is x - 3
in 7 years, the age of Roberto is x + 7; the age of Carolyn is x - 3 + 7 = x + 4
because In 7 years the sum of their ages will be 81 =>
x + 7 + x + 4 = 81
⇔ 2x + 11 = 81
⇔ 2x = 70
⇔ x = 70/2 = 35
=> the age of Roberto is 35

Mr. Roberts had $9,512 in savings. He saved another $488. He then used all his money to buy 500 books. He sold the books for $35 each. How much did Mr. Roberts earn from selling each book? a. Mr. Roberts earned $ from selling each book. b. Travis got $20 as the answer or the amount Mr. Roberts earned from selling each book. Is his answer correct? yes no c. Tell why Travis is or is not correct.
Answer:
a. Profit from each book = $15
b. No, Travis was wrong.
c. Travis isn't correct because Mr. Roberts made $15 from the sales of each book.
Step-by-step explanation:
Given the following data;
Number of books bought = 500
Selling price = $35
Robert savings (cost price) = $9,512 + $488
Robert savings (cost price) = $10,000
Purchasing price = $10,000/500 = $20
Revenues from book sold = 500 * 35 = $17,500
Total profit = Revenues - Cost price
Total profit = $17,500 - $10,000
Total profit = $7,500
To find the amount earned from each book;
[tex] Profit \; from \; each \; book = \frac {Total \;profit}{Numbers \; of \; book} [/tex]
Substituting into the equation, we have;
[tex] Profit \; from \; each \; book = \frac {7500}{500} [/tex]
Profit from each book = $15
Therefore, Mr. Roberts earned $15 from selling each book.
Check:
Selling price = purchasing price + profit = $20 + $15 = $35

Answer:
1. sin(x) = a/c; cos(x) = b/c; tan(x) = a/b
2, 3 see below
Step-by-step explanation:
1. The mnemonic SOH CAH TOA reminds you of the relationships between trig functions and sides of a right triangle:
Sin = Opposite/Hypotenuse ⇒ sin(x) = a/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = b/c
Tan = Opposite/Adjacent ⇒ tan(x) = a/b
__
2. The attachment shows the two special right triangles. The 30-60-90 right triangle has sides in the ratio 1 : √3 : 2. The 45-45-90 isosceles right triangle has sides in the ratio 1 : 1 : √2.
These ratios can be used to write proportions that help you find the length of a missing side.
Example:
Suppose the triangle in problem 1 has x = 30°, and a = 10. Then we could find the length of missing side 'c' using a proportion involving the short side and the long side (hypotenuse).
2/1 = c/10 ⇒ c = 20
__
3. In a right triangle, the acute angles are complementary. The side adjacent to one acute angle is the side opposite the other. So the sine of one of the angles is the cosine of the other, and vice versa. This means the sine of an angle is the cosine of its complement, and vice versa.
__
Comment on question 3
The wording of this question is a little strange. Sine and cosine are not complementary. Rather, the angles for which those functions have the same value are complementary.
Which point represents 3.9?
Answer:
What do you mean there is not a graph...do you have a picture?
Step-by-step explanation:
Answer: B
Step-by-step explanation:
A = 3.8
B = 3.9
C = 4.0
D = 4.2
You take 4.5 - 3,6 = 0.9, so each big line should be .3.

Answer:
2876 books
Step-by-step explanation:
If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...
y1 = 12841 +24.25x
y2 = 48072 +12x
These costs will be equal when ...
y1 = y2
12841 +24.25x = 48072 +12x
12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x
x = 2876 . . . . . . . . . . divide by 12.25
The costs will be the same for production of 2876 books.

Ross wants to know what interest rate he needs to make his $800 grow to
$1000 in 4 years.
Answer:
Why?:
The interest formula is A = P(1+r/m)^mt
A is the Amount, P is principal (initial investment), R is rate, M is times per year (not used) and T is time.
So if we want 1000 = 800(1+r)^4, we need to find R. In this case, R is about 5 percent. (I'm not super confident, so see if you have other answers)

Find the equation of the linear function represented by the table below in slope intercept form.
Answer:
Y=1x-7
Step-by-step explanation:
First use two points to find the slope. I used the first 2. The formula is (y1-y2)/(x1-x2). So (6-8)/(1-3)= -2/-2 = 1. Then you plug in a point and the slope for the equation y1-y2=m(x1-x2). I am using the first point and m is the slope which is 1. Y-6 = 1(x-1)
y-6 = 1x -1 then get y by itself
y=1x-7

The domain is -5
The range is y < 5
The range is -5y<1
Answer:

Since y is always less than 5, y cannot be equal to it since the highest value of y was about 4.
In each problem, angle C is a right angle. Solve each triangle rounding answers to the nearest
tenth.
a= 7.7 ft, b= 16 ft
9514 1404 393
Answer:
c = 17.8, A = 25.7°, B = 64.3°
Step-by-step explanation:
Side c can be found from the Pythagorean theorem:
c = √(a² +b²)
c = √(7.7² +16²) = √315.29
c ≈ 17.8 . . . feet
__
The tangent relation is ...
Tan = Opposite/Adjacent
tan(A) = a/b = 7.7/16
A = arctan(7.7/16)
A ≈ 25.7°
B = 90° -25.7°
B = 64.3°
