[x + 3y = -4] [2x + 6y = 5]

stealth61 [152]

Step-by-step explanation:

x+3y=-4(eqn1)

x=-4-3y

from (eqn 2)

2(-4-3y)+6y=5

-8-6y+6y=5

y=5+8=13.

y=13

from eqn 1

x+3(13)=-4

x+39=-4

x=-4-39

x=-43.

The slope of the line whose equation is 3y + 2x = 1 is: A.)-2/3 B.)-3/2 C.)1/3

mojhsa [17]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3y + 2x = 1 into this form

Subtract 2x from both sides

3y = - 2x + 1 ( divide all terms by 3 )

y = - $\frac{2}{3}$ x + $\frac{1}{3}$ ← in slope- intercept form

with slope m = - $\frac{2}{3}$ → A

ss7ja [257]

Answer:

$4x + 3 < 7 \\ 4x + 3 - 3 < 7 - 3 \\ 4x < 4 \ \\ 4x \div 4 < 4 \div 4 \\ x < 1$

$3x - 8 > 7 \\ 3x - 8 + 8 > 7 + 8 \\ 3x > 15 \\ 3x \div 3 > 15 \div 3 \\ x > 5$

3*1=34 --> split this into two parts. 3*1 is 3 and 3+1 is 4 so put them together and you get 34.
