Which statement about the graph of y= 3x+5 is correct?
a. The line passes through the ordered pair (3, 0) and has a slope of 5.
b. The line passes through the ordered pair (0,5) and has a slope of 3.
c. The line passes through the ordered pair (5,20) and has a slope of 5/3
d. The line passes through the ordered pair (3, 14) and has a slope of 3/5
Answer:
b. The line passes through the ordered pair (0,5) and has a slope of 3.
Step-by-step explanation:
The equation given is in slope-intercept form.
[tex]y= mx+b[/tex]
m = slope
b = y-intercept
The slope is 3 in the equation. 3 is in m's spot.
[tex]y=\boxed{m}x+b\\\\y=\boxed{3}x+b[/tex]
The y-intercept is 5. This means that the line will pass through (0,5).
[tex]y=mx+\boxed{b}\\\\y=3x+\boxed{5}[/tex]
The correct option should be B.
Hope this helps.

Two buses leave towns 304 miles apart at the same time and travel toward each other. One bus travels 14 mih slower than the other. If they meet in 2 hours, what is the rate of each bus?
Answer:
The faster bus moves at 83mi/h and the slower one moves at 69mi/h.
Step-by-step explanation:
Let's define:
R₁ = rate of bus 1, this is the faster one.
R₂ = rate of bus 2, this is the slower one.
We know that one bus travels 14mi/h slower, then:
R₂ = R₁ - 14mi/h.
Now we know that:
Distance = Speed*Time.
If we add the distances that both busses travel in 2 hours, it should be equal to the initial distance between the buses, then:
R₁*2h + R₂*2h = 304 mi
Then we have the two equations:
R₂ = R₁ - 14mi/h
R₁*2h + R₂*2h = 304 mi
The first step is to replace the first equation in the second one, to get:
R₁*2h + (R₁ - 14mi/h)*2h = 304 mi
And now we can solve this for R₁.
R₁*2h + R₁*2h - 14mi/h*2h = 304 mi
R₁*4h - 28mi = 304mi
R₁*4h = 304mi + 28mi = 332mi
R₁ = 332mi/4h = 83mi/h
The faster bus moves at 83mi/h
And we know that the slower one moves at 14mi/h slower than this, then:
R₂ = R₁ - 14mi/h = 83mi/h - 14mi/h = 69 mi/h

A plot of land is an irregular triangle with a base of 112 feet and a height of 47 feet. What is the area of the plot?
The area of irregular triangle is 2632 sq. ft.
What is Triangle?A triangle is a closed shape with 3 angles, 3 sides, and 3 vertices. A triangle with three vertices P, Q, and R is represented as △PQR.
Here, given dimension of irregular triangle;
base = 112 feet.
height = 47 feet.
we know that,
Area of triangle = 1/2 X Base X Height
= 1/2 X 112 X 47
= 56 X 47
= 2632 ft²
Thus, the area of irregular triangle is 2632 sq. ft.

Miya is selling grapefruit and nuts for a fundraiser. The grapefruits cost 5 dollars each and a bag of nuts cost 15 dollars each. She sells 30 items and made 250 dollars. How many grapefruits did she sell?
Answer:
A) 5G + 15N = 250
B) G + N = 30 We'll multiply B) by -5
B) -5G -5N = -150 then we add A)
A) 5G + 15N = 250
10N = 100
N = 10 bags of nuts ($150.00)
We put N=10 into A)
A) 5G + 150 = 250
A) 5G = 100
G = 20 Grapefruits ($100.00)

The surface areas of two similar containers are 1500 cm² and 375 cm². The
volume of the smaller container is 450 cm squared. What is the volume of the larger
container, to the nearest whole number?*
Answer:
1800cm^3
Step-by-step explanation:
Since you know that the containers are simular your gonna want to know the difference. so you would do 1500/375 (The two Surface areas) to get 4 which is the differnce.
The Volume now looks like x/450 - So to find x or the volume of the larger container you would multiply 450x4 which equals 1800

Which of the following fractions compares BC to BD?

Answer:
2/3
Step-by-step explanation:

The fraction that compares BC to BD is 2/3.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
The distance between B and C is 2-0 = 2 units horizontally and 1-1 = 0 units vertically, so BC is a horizontal segment of length 2 units.
The distance between B and D is 3-0 = 3 units horizontally and 1-1 = 0 units vertically, so BD is also a horizontal segment of length 3 units.
Therefore, BC/BD = 2/3.
So the fraction that compares BC to BD is 2/3.

Answer:
[tex]\frac{cosec\alpha(1-cosx^{2} \alpha ) }{sin\alpha cos\alpha } = sec\alpha[/tex]
Step-by-step explanation:
Step(i):-
Given that the trigonometric function
[tex]\frac{cosec\alpha(1-cosx^{2} \alpha ) }{sin\alpha cos\alpha }[/tex]
we know that sin²∝ + cos²∝ = 1
⇒ sin²∝ = 1- cos²∝
Now we have to simplify the given trigonometric function
= [tex]\frac{cosec\alpha(sin^{2} \alpha ) }{sin\alpha cos\alpha }[/tex]
= [tex]\frac{cosec\alpha(sin \alpha ) }{ cos\alpha }[/tex]
Step(ii)
we know that cosec∝ = 1/ sin∝
= [tex]\frac{\frac{1}{sin\alpha } (sin \alpha ) }{ cos\alpha }[/tex]
After cancellation sine function, we get
= [tex]\frac{1 }{ cos\alpha } = sec\alpha[/tex]
Final answer:-
[tex]\frac{cosec\alpha(1-cosx^{2} \alpha ) }{sin\alpha cos\alpha } = sec\alpha[/tex]

Jada has a vegetable garden. Two-thirds of the garden is made up of tomato plants. Four-fifths of the tomato plants are beefsteak tomatoes. What portion of the garden is made up of beefsteak tomatoes?
Answer:
8/15
Step-by-step explanation:
The problem states that Jada has a vegetable garden made up of 2/3 tomato plants, of which 4/5 are beefsteak tomatoes. Therefore, to determine the portion of the garden that is made up of beefsteak tomatoes, both fractions must be unified in the same common divisor.
Thus, since the common least multiple of 3 and 5 is 15 (3 x 5), the fraction 2/3 can be calculated as 10/15. In turn, of those 10, 4/5 are beefsteak tomatoes, which can be calculated as 8/10, since the common lower multiple of 5 and 10 is exactly 10.
Therefore, 8/15 of Jada's vegetable garden are beefsteak tomatoes.
Answer:
8/15
