elimination method
x-5=-y
3x-10=2y​

Answers

Answer 1

Answer:

(4,1)

Step-by-step explanation:

Multiply the first equation by -3

(x-5=-y)*-3 = -3x+15=3y

Then combine like terms with the new equation and the second equation

(-3x+15=3y) + (3x-10=2y) = 5=5y

Divide 5 by both sides

1=y

Plug in 1 for y in an equation. Doesn’t matter which one and solve

x-5=-(1)

Distribute the negative sign to the 1

x-5=-1

Add 5 to both sides

x=4

Answer 2

X-5= -y
-X+5=y
-4+5=y
1=y

3X-10=2(-2+5)
3X-10= -2X+10
3X+2X=10+10
5x=20
X=4

Step-by-step explanation:

Under a translation < 5, - 9 >

5 is added to the original x- coordinate and 9 is subtracted from the original y- coordinate, that is

A(1, 4 ) → A'(1 + 5, 4 - 9 ) → A'(6, - 5 )

B(2, - 2 ) → B'(2 + 5, - 2 - 9 ) → B'(7, - 11 )

C(- 3, 2 ) → C'(- 3 + 5, 2 - 9 ) → C'(2, - 7 )

1. Look at the following correlation scatter plot. What type of a correlation is it?
a. Negative correlation
b. Positive correlation
c. Zero correlation
d. All of the above

Answers

Scatter plot is missing, so i have attached it.

Answer:

C : zero correlation

Step-by-step explanation:

A correlation is said to be negative between two variables when they are related in such a manner that when one variable increases, the other variable decreases and vice versa.

However, a correlation is said to be Positive when one variable increases as the other increases as well and vice versa which means they both move in the same direction.

However, in the image of the scatter plot attached, we see that it is neither positive or negative correlation as there is no clear visible relationship between the variables on the x and y axis.

Thus, we can say there is zero correlation.

what is 18 rounded to the nearst 1/4

Answers

Answer:

18

Step-by-step explanation:

1/4 is close to 0 so 18 rounded to the nearest ones place is just 18

Answer:

20

Step-by-step explanation:

When we round to the nearest ten, we will round up to a number that has a zero in the ones place but we have to look at the number in the ones place before we round to determine the number in the tens place. The rule is if the number in the place before the place we need to round (in this case the ones place would be what we look at to determine the rounded tens place) 1-4 is going to round down, keeping the tens place the same and the ones place goes to zero, and if the ones number place is 5-9 then we round up, bringing the ones to zero and the tens up by one tens place.

use what you know about translations of functions to analyze the graph of the function f(x) = (0.5)^x-5+8 you may wish to grab it and its parent function y=0.5^x on the same axes
The parent function y=0.5^x is _____ across its domain because its base b is such that

Answers

First box is: decreasing

Second box: 0< b< 1

Third box: Up

Fourth box: Right

The parent function y=0.5^x is decreasing across its domain because its base b is such that (0<b<1) and function shifts it 8 units up and 5 units right.

What is translation of a function?

Translation of a function is shifting the function from its original place in the graph.

Types of translation -

Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)+c shifts the graph c units down and by replacing parent function with f(x)-c shifts the graph b units up.

The functions of the graph given in the problem as,

[tex]f(x) = (0.5)^{x-5}+8[/tex]

The parent function of the graph is,

[tex]y=0.5^x[/tex]

In the parent function, the 5 units subtracted, and 8 units added outside the function. Thus, the function shifts the parent function 8 units up and 5 units right.

Thus, the parent function y=0.5^x is decreasing across its domain because its base b is such that (0<b<1) and function shifts it 8 units up and 5 units right.

Ann and Bill share an amount of money in the ratio 7:n
Ann gets 28% of the money.
Work out the value of n​

Answers

Answer:

48

Step-by-step explanation:

The value of n will be;

⇒ n = 18

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

Given that;

Ann and Bill share an amount of money in the ratio = 7 : n

And, Ann gets 28% of the money.

Now,

Since, Ann and Bill share an amount of money in the ratio = 7 : n

And, Ann gets 28% of the money.

Thus, Bill gets the money = 100 - 28%

                                        = 72%

So, The unit ratio for the Ann = 28 / 7

                                              = 4

Hence, Bill ratio will be = 72/4

                                    = 18

Thus, The ratio of an amount of money = 7 : 18

Hence, The value of n = 18.
