Answer: y = 1/2x + 6

Step-by-step explanation:

b = y1 - m • x1

Plug everything in:

b = 5 - (1/2) • -2

= 6

Written in y = mx + b is:

y = 1/2x + 6

Use the elimination method to solve the system of equations. Choose the

Anarel [89]

Answer:

D. (6,6)

Step-by-step explanation:

Given the system of two equations

$\left\{\begin{array}{l}3x+5y=48\\ \\-3x+5y=12\end{array}\right.$

1. Add these two equations:

$3x+5y-3x+5y=48+12\\ \\10y=60\\ \\y=6$

2. Subtract these two equations:

$(3x+5y)-(-3x-5y)=48-12\\ \\3x+5y+3x-5y=36\\ \\6x=36\\ \\x=6$

Hence, the solution to the system is (6,6)

Plz help asap and plz show me how to do this..thxs I really need help with this

G is the answer because if you set x as the value of B, then x+(x+10)+(x+30)=180 so x=46.67. then you add 10 to that because the value of A is 10 more than B

Solving for each equation:

A: True.

$\frac{n}{2} +3 *4 = \frac{n}{2}+12\\\\\frac{n}{2} + 12 = \frac{n}{2} + 12$

B: False.

$\frac{1}{3}z+\frac{2}{3}z * 9 = 9z\\\\\frac{1}{3} z+6z = 9z$

C: True, given that y = 1

$-8y +4.3y + 3.7 = 0\\\\-3.7y = -3.7$

D: True, given that b = 6.66667

$12-1.8b+1.8b=1.8b\\12 = 1.8b$

E: True.

$\frac{m}{8} + 7(\frac{m}{8} ) =m\\\\\frac{m}{8} + (\frac{7m}{8} )= m\\\\\\\frac{8m}{8} = m\\$
