Answer:

Infinitely many solutions

Step-by-step explanation:

Given:

y= 2x+5

1/2y = x+5/2

Multiplying 2 with both sides will give:

2( 1/2y) = 2(x+5/2 )

y= 2x+5

As both the equations are similar with same slope m=2 and y-intercept= 5

thus the system of equation will have infinite solution. Graph will show single line.

What's the Error? Explain the error. Find the correct solution.<br>19 + (-31) = 12

Alex

Answer:

The answer is incorrect because 12 should be negative not positive.

Step-by-step explanation:

1. 19 + -31 = - 12

2. Twelve is negative because if you were to start off at -31 and add 19 the answer would remain negative since -31 in a sense is "bigger" than 19. You would need more of a positive number to make -31 positive such as 40.

40+ -31 = 9

Which equation is correctly rewritten to solve for x?

ikadub [295]

Answer:

Option (A)

Step-by-step explanation:

Te given equation is,

-qx + p = r

Toe find the value of x,

By subtracting p from both the sides of the equation.

-qx + p - q = r - q

-qx = r - q

By dividing the whole equation by (-q),

$\frac{-qx}{(-q)}=\frac{r-p}{-q}$

x = $-\frac{r-p}{q}$

x = $\frac{p-r}{q}$

Therefore, Option (A) will be the answer.
