Which graph represents the linear function y= -5x + 2

Semmy [17]

Look at all the options... the correct one should have a negative slope (so it would be a line decreasing), and it should also intersect on the Y axis at 2.

Solve the system by elimination find the ordered pair that is the solution

Amanda [17]

Answer:

x = 1

y = -24

Step-by-step explanation:

8x + y = -16

-3x + y = -5

Subtract equation one from equation two

8x - -3x + y - y = -16 - - 5

8x + 3x = -16 + 5

11x = 11

Divide both sides by 11

11x/11 = 11/11

x = 1

Now substitute 1 for x in either of the equations to get y.

Using equation one, we have

8x + y = -16

8 x 1 + y = -16

8 + y = -16

Subtract 8 from both sides

8 - 8 + y = -16 - 8

y = -24

x = 1

y = -24

Which method would be the simplest way to solve the system?

Lunna [17]

It would be elimination (C) because 7x and -7x can be eliminated into 0.

  7x + 5y = 19
  -7x - 2y = -16
  3y = 3
3 3
  y = 1
  7x + 5y = 19
7(1) + 5y = 19
7 + 5y = 19
- 7 - 7
5y = 12
5 5
y = 2.4
  (x, y) = (1, 2.4)

What is the value of m

zhuklara [117]

Answer:

$x=16\frac{2}{3}$

Step-by-step explanation:

Since the rectangles are similar, that means that corresponding sides are proportional. Therefore, the ratio of similitude is 5/3 (GH and CD are corresponding sides and the ratio between their lengths is 5/3). If the ratio of similitude is 5/3 and two corresponding sides are m and 10, then we can make an equation:

$\frac{m}{10}=\frac{5}{3}$
