What are the coordinates of point A?​

Mathematics
1 answer:
Ratling [72]2 years ago
4 0

Answer:

  (d)  (7, -5)

Step-by-step explanation:

The x-coordinate is listed first in an ordered pair. It is found on the horizontal scale. The point is on the grid line halfway between 6 and 8, so is presumed to have an x-coordinate of 7.

The y-coordinate is listed second in an ordered pair. It is found on the vertical scale. The point is on the grid line halfway between -4 and -6, so is presumed to have a y-coordinate of -5.

The coordinates of point A are (x, y) = (7, -5).

__

<em>Additional comment</em>

As in the case here, you will often run across graphs that don't have markings on every grid line You are expected to be able to figure out the value of a grid line based on the spacing of the marked lines.

It is a good idea to get familiar with reading coordinates of a point on a graph, as you will be doing it a lot.

Elanso [62]

Answer:

(-3, 0)

Step-by-step explanation:

\:  \:  \: 2x + 3y =  - 6 \\ -2x + 3y =  \:  \:  \: 6   \\   \frac{ +  \:  \:  \:  \:  \:  \:  -   \:  \:  \:  \:  \:  \: =  - }{ }{}  \\  \:  \:  \:   4x \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  - 12 \\ \\  x =  \frac{ - 12}{4}  \\  \\ x =  - 3

now,

-2( - 3) + 3y = 6 \\  6 + 3y = 6 \\ 3y = 6 - 6 \\ 3y = 0 \\ y =  \frac{0}{ 3}  \\ y = 0

thus, (-3, 0)

5. Simplify: 56 = 7 - 3 [4 + {8 - 4 ( 4 + 5 - 3 )}]​
shutvik [7]

Answer:

36

Step-by-step explanation:

56=7-3[4+{8-4(4+5-3)}]

56=7-3[4+{4(4+5-3)}]

56=7-3[4+{16+20-12)}]

56=7-3[4+24]

56=4[28]

56=92

56-56=92-56

Answer:

Step-by-step explanation:

1.

Equation one:

x = -5, x = -1 (Both are real)

Equation two:

No real solutions

Equation three:

x = -3 (Real)

Equation four:

No real solutions

2.

The easiest way to figure out if an equation has real solutions is to factor it. If it is factorable, then it has real solutions. If it isn't, then it doesn't have real solutions.
