m = \frac{y_{2} - y_{1}}{c_{2} - x_{1}} = \frac{-5 - 1}{7 - (-1)} = \frac{-6}{7 + 1} = \frac{-6}{8} = \frac{-3}{4} = -\frac{3}{4}

y - y₁ = m(x - x₁)
 y - 1 = ⁻³/₄[x - (-1)]
 y - 1 = ⁻³/₄(x + 1)
 y - 1 = ⁻³/₄(x) - ³/₄(1)
 y - 1 = ⁻³/₄x - ³/₄
    +1          + 1
      y = ⁻³/₄x + ¹/₄

Solve the equation.<br> -5=x+3<br> Ox=3<br> Ox=-3<br> Ox=8<br> Ox=-8
weqwewe [10]
Answer:
x= -8

Explain:
You first have to make the variable by itself so you subtract 3 on both sides. The x is by itself and you finish by subtracting -5 to 3 and you get the answer x = -8

Hope this helps

a(x+b)=4x+10 in the equation above a and b are constants. if the equation has infinitely many solutions for X, what is the value
xeze [42]

Answer:

b= \frac{5}{2}

Step-by-step explanation:

Given

a(x+b)=4x+10\\ax+b= 4x+10\\

Now we know that system has infinite solution for x

\frac{a_1}{a_2}=\frac{b_1}{b_2}

in above equation.

a_1=a, a_2=4, b_1=ab,b_2=10\\

∴\frac{a}{4}=\frac{ab}{10}\\\therefore b=\frac{10\times a}{4\times a}=\frac{5}{2}

What is the answer to -7=-12 (-2)+B please help!
insens350 [35]
I would solve it for B, but that's just what I think. So you would do -12 time -2 which is 24, then subtract 24 from both sides so that you would get B=-31
