You recently saw some pretty paintings in an art museum in New York City. The artist's name is Claude Monet. Since your teacher

Lyrx [107]

Typing "Claude Monet" in the subject field makes the most sense, an author is someone who holds a big part in writing a story for literature, depending on what that work is, and your not looking for new york or an art museum in the library, so answer C is the best one

Im doing decimals greatest to least and i need help with number 12 and 13

erma4kov [3.2K]

(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)

1. Just because a number looks big, doesn't mean it is big

Example: 1.00000000000001 < 1.1

just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"

2. Negative numbers are... opposite. and they are less than positive numbers

-3.4 > -4.1

Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers

I hope these tips helped!! :D

The graphs of which of these pairs of linear equations intersect at the point (-3, 2)? Select all that apply.

Cloud [144]

Answer:

Options B and E.

Step-by-step explanation:

We want to see for which systems the point (-3, 2) is a solution (a solution of a system means that both equations intersect in that point).

The point (-3, 2) is a solution of the system only if this point belongs to both linear equations in the system.

Then for each system, we need to replace x by -3 and y by 2 in both equations and see if the equality is true or not.

A)

6x - y = 15

-3x + 4y = -18

In the first equation we have:

6*(-3) - (2) = 15

-18 - 2 = 15

-20 = 15

This is false, so we can discard option A.

B)

2x + y = -4

3x + 2y = -5

In the first equation we have:

2*(-3) + 2 = -4

-6 + 2 = -4

-4 = - 4

This is true, now let's look at the other equation.

3*(-3) + 2*(2) = -5

-9 + 4 = -5

-5 = - 5

This is also true, then the point (-3, 2) is a solution for both equations, then the point (-3, 2) is a solution for the system.

C)

x + 8y = 19

4x - 5y = 2

In the first equation we have:

(-3) + 8*(2) = 19

-3 + 16 = 19

13 = 19

This is false, then we can discard option C.

D)

8x + y = 22

-2x - 5y=4

In the first option we have:

8*(-3) + 2 = 22

-24 + 2 = 22

-22 = 22

This is false, so we can discard option D.

E)

5x - y = -17

x + 4y = 5

In the first option we have:

5*(-3) - (2) = -17

-15 - 2 = -17

-17 = -17

This is true, now let's look at the other equation:

(-3) + 4*(2) = 5

-3 + 8 = 5

5 = 5

This is also true, then the point (-3, 2) is a solution for both equations in the system, which means that the point (-3, 2) is a solution for the system.

Then the correct options are B and E.

What is the equation of a line passing through (-3, 7) and having a slope of -1/5?

andrey2020 [161]

Thank you for coming to Brainly with your questions!

I believe the answer is:

$y = - \frac{1}{5} x + 6 \frac{1}{5}$ . The equation to find this is:
y - y1 = m(x - x1). So you plug in the slope for "m", the x coordinate for "x1" and the y coordinate for "y1". After you do that, it should look like this:

$y - 7 = - \frac{1}{5} - 1 \frac{1}{5}$ .

Then you just add 7 to both sides to get y by itself, so that is how I got the answer.

I hope this helps you! Please mark Brainliest! Lemme know if I can help you with any further questions!
