Answer:

y = 5 − 2x

4x + 2y = 10

(Infinite solutions)

x = 26 − 3y

2x + 6y = 22

(No solution)

5x + 4y = 6

10x − 2y = 7

(Single solution)

x + 2y = 3

4x + 8y = 15

(No solution)

3x + 4y = 17

-6x = 10y − 39

(Single solution)

x + 5y = 24

5x = 12 − y

(Single solution)

Mark incorrectly solved the inequality -4(5/2+3/2x) > 8. His work is shown. Which step shows an error based on the inequality

aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

$-4(\frac{5}{2}+\frac{3}{2}x)>8$

Now solving this expression step by step.

First -4 distributed over parentheses.

$(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8$

Now solving bracket term, we get:

$-10-6x>8$

Now taking like terms together, we get:

$-6x>8+10$

$-6x>18$

$-x>3$

Now multiplying this expression by (-1), we get:

$x>-3$

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8

Answer:

a = m
b = n

Step-by-step explanation:

The axes of symmetry are shown and labeled m and n. Reflection across either (or both) axis of symmetry will map the figure to itself. Apparently, you want to designate those reflections as ...

Ra . . . where a = m

Rb . . . where b = n
