Match each system of equations with its number of solutions

Answers

Answer 1

Answer:

Answer:

1st: 0 solutions

2nd: infinitely many solutions

3rd: 1 solution

Step-by-step explanation:

1st: add both equations and the result is 0 = 4 ⇒ inconsistent, no solution

2nd: add both equations and the result is 0 = 0 ⇒ it's true, for all x and y values

3rd: add both equations and obtain: 16x = 32 ⇒ x = 2,

then if you want to obtain y, replace x in any of both equations.

Conclusion is that only 1 solution (x = 2 and a unnique value for y) is obtained.

hree different stocks were ordered. The purchase prices were 8 ⅜ dollars, 12 ⅛ dollars and 15 ⅜ dollars.how much was paid for all three stocks?

Answers

when you add all of the totals together your total amount will be $35.875

8 3/8 + 12 1/8 + 15 3/8

8 + 12 + 15 = 35
3/8 + 1/8 + 3/8 = 7/8

total = 35 7/8

Answer:

$(6x*x^(3))/(y^(2))\n\n$

Step-by-step explanation:

$a^(-m)=(1)/(a^(m))\n\n(1)/(a^(-m))=a^(m)\n\na^(m)*a^(n)=a^(m+n)\n\n\n(6xy^(-2))/(x^(-3))=(6*x*x^(3))/(y^(2))\n\n=(6x^((1+3)))/(y^(2))\n\n=(6x^(4))/(y^(2))$

I think it’s y^2.

A fishery is an area with the specific purpose of controlling fish populationsfor commercial or recreational fishing. Population dynamics describe how a
fish population changs over time. The population is changed by birth, death,
and migration of fish. While the supply of fish (population growth) can be
modeled with a linear equation, so can the demand of fish (the amount caught).
In one commercial venture, fishermen recorded their daily catch in an ocean
fishery. Using their data, the demand model for the total number y of fish caught
for x days is y = 349x + 50. What is the meaning of the slope?

Answers

Using linear function concepts, it is found that the slope of 349 means that each day, the number of fish caught increases by 349.

A linear function is modeled by:

$y = mx + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0.

In this problem, the equation for the number of fish caught after x days is given by:

$y = 349x + 50$

The slope is of 349, which means that each day, the number of fish caught increases by 349.

Bertha and Vernon are competing in a diving competition. Bertha's dive ended -24 m from the starting platform. Vernon's dive ended -4 m from the starting platform. How many times farther was the end of Bertha's dive than the end of Vernon's dive?A.

-6

B.

6

C.

20

D.

-20

help help help

Answers

Answer:

B. Bertha's dive ended 6 times farther than Vernon's dive.

Step-by-step explanation:

We have that,

Bertha's dive ended -24 m from that starting point.

Vernon's dive ended -4 m from that starting point.

So, we get that,

Bertha's end point = 6 × Vernon's end point

i.e. -24 = 6 × (-4)

So, we see that,

Bertha's dive ended 6 times farther than Vernon's dive.

What is ^3 sqrt(x^3)/^5 sqrt(x^2) in simplest form?x^3/5
x^5/3
x^9/15
x^15/9

Answers

The correct answer is x^3/5

This is how to solve the question:
We have to separate the numerator from the denominator in order to easily simplify the whole expression.

3 sqrt(x^3) = x
5 sqrt(x^2) = x - 2/5

Then form the fraction

= x / (x - 2/5)
= x^3/5

So the correct answer is x^3/5

The correct answer would be a. x^3/5
