7x-5y=15
solve for y, please help
Answer:
7x-15/5
Step-by-step explanation:
Given :-
A linear equation in two variable is given to us . That is 7x - 5y = 15.And , we need to solve for y in terms of x . So taking the given equation ,
[tex]:\implies[/tex] 7x - 5y = 15
[tex]:\implies[/tex] -5y = 15 - 7x
[tex]:\implies[/tex] 5y = 7x - 15
[tex]:\implies[/tex] y = ( 7x - 15)/5
Hence the required answer is 7x-15/5.Don’t give me a website pls

Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range? a. No: we would have no information about the domain. c. Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≤ n. b. No: we would need to know if the vertex is a minimum or a maximum. d. Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≥ n.

Jane will rent a car for the weekend she can choose one of the two plans the first plan has an initial fee of $42 in cost of additional $.12 per mile driven the second plan has an initial fee of $55 in cost additional seven cents per mile driven
Answer:
260m
$73.2
Step-by-step explanation:
For what amount of driving do the plans cost the same?
What the cost when the two plans cost the same?
first plan = 42 + 0.12m
second plan = 55 + 0.07m
42 + 0.12m = 55 + 0.07m
collect like terms
55 - 42 = 0.12 - 0.07m
13 = 0.05m
m = 260
42 + 0.12(260) = 73.2

Dana rasied the score on a video game from 300 points to 390 points. By what percentage did Dana raise the score?
Answer: 30%
Step-by-step explanation:
First find the difference between the old score and the new:
= 390 - 300
= 90 points
To find the percentage increase, divide the difference by the original score:
= 90 / 300
= 30%
A rectangular prisim has a base with an area of 200cm squared. The volume of the prism is 3,000cm cubed. What is the height of the prism?
Answer:
[tex]Height = 15cm[/tex]
Step-by-step explanation:
Given
[tex]Base\ Area = 200cm^2[/tex]
[tex]Volume = 3000cm^3[/tex]
Required
The height
Volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
Make Height the subject
[tex]Height = \frac{Volume}{Base\ Area}[/tex]
This gives
[tex]Height = \frac{3000cm^3}{200cm^2}[/tex]
[tex]Height = \frac{3000}{200}cm[/tex]
[tex]Height = 15cm[/tex]

Answer:
Hello! answer: 12
Step-by-step explanation:
Assuming this is the Pythagorean theorem we would usually solve for c but c is already found so we have to work backwards so... 15 × 15 = 225
9 × 9 = 81 225 - 81 = 144 √144 = 12 therefore 12 is the answer Hope that helps!
If tan0 = 3/4, find sin0
Answer:
b
Step-by-step explanation:
Answer:
[tex]\text{b. }\sin \theta =\frac{3}{5}[/tex]
Step-by-step explanation:
In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\tan \theta =\frac{3}{4}[/tex] as given in the problem, then the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].
The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse. Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h).

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every
morning. His goal is to run at least 6 miles by the end of the week.
Which inequality represents the least number of days after Monday that Joseph needs to run
to reach his goal? *
Answer:
2 + 1 1/3x ≥ 6
x ≥ 3 days
Step-by-step explanation:
Monday = 2 miles
Other days = 1 1/3 miles
x = least number of days after Monday that Joseph needs to run
to reach his goal
Total miles = 6 miles
The inequality is
2 + 1 1/3x ≥ 6
1 1/3x ≥ 6 - 2
1 1/3x ≥ 4
4/3x ≥ 4
Divide both sides by 4/3
4/3x ÷ 4/3 ≥ 4 ÷ 4/3
x ≥ 4 × 3/4
x ≥ 3 days

The term "number system" refers to a mathematical notation or method used to represent numbers. It provides a structured way to count, measure, perform calculations, and express numerical quantities. Different number systems exist, and they vary based on the symbols used, the base or radix of the system, and the rules for representing numbers.
The most common number system used worldwide is the decimal system, also known as the base-10 system. In the decimal system, numbers are represented using ten digits (0-9), and the value of each digit is determined by its position or place value within the number.

A company produces packets of soap powder labeled "Giant size 32 Ounces." The actual weight of soap powder in a box has a normal distribution with a mean of 33 oz. And a standard deviation of 0.8 oz. The proportion of packets that are underweight (i.E. Weight less than 32 oz.) are
Answer:
0.1057
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = 32 oz
μ is the population mean = 33 oz
σ is the population standard deviation = 0.8oz
For x < 32 oz
z = 32 - 33/0.8
z = -1.25
Probability value from Z-Table:
P(x<32) = 0.10565
Approximately = 0.1057
Therefore, the proportion of packets that are underweight (i.e. Weight less than 32 oz.) are 0.1057.

You are planning to build a walkway that surrounds the area of a rectangular garden. The width of the walkway around the
garden is the same on every side. Which of the following polynomials represents the total area of the garden and
walkway?
Answer:
B. (2x + 10)(2x + 9)
Step-by-step explanation:
Length (L) of the garden and walkway = x + 10 + x = (2x + 10) ft
Width (W) of the garden and walkway = x + 9 + x = (2x + 9)
Area of the garden and walkway = area of rectangle = L*W
= (2x + 10)(2x + 9)
The polynomial representing the total area of the garden and walkway = (2x + 10)(2x + 9)

male female eats oysters 205 113 does not eat oysters 98 322 what is the probability that one of the people chosen from this survey was a female and does not eat oysters could someone explain?
Answer:
322 /738 ; 0.436
Step-by-step explanation:
__________________ M____ F__
Eat oysters ________ 205 __ 113
Does not eat oysters _ 98 __ 322
Probability of choosing a female and does not eat oysters :
Number of (F n Does not eat oyster) = 322 (from table)
Total number of sample : (205+98+113+322) = 738
Hence,
Probability of choosing a female and does not eat oysters ;
Number of (F n Does not eat oyster) = 322 (from table) / total number of samples
= 322 / 738
= 0.436
What is the total area, in square feet, of the house and backyard? A) 200 B) 400 C) 4,000 D) 5,200
Answer:
Area = 5200 ft²
Step-by-step explanation:
First let us find the area of the house.
Area = l × w
Area = 30 ft × 40 ft
Area = 1200 ft²
Now let us find the area of the backyard.
Area = l × w
Area = 80 ft × 50 ft
Area = 4000 ft²
Now that we have found the area of the house and the backyard, it asks us to find the total area of house and the backyard. To find the answer, you will both, the area of house and the area of the backyard.
Area of house + Area of backyard
1200 ft² + 4000 ft²
5200 ft²
