Answer:

  a, c, b

Step-by-step explanation:

Collect terms, subtract the constant, divide by the y-coefficient.

(a) 4y + (y - 1) = 29   ⇒   y = 6

(c) (2y + 3) - 4 = 9​   ⇒   y = 5

(b) 4y - y + 1 = 13   ⇒   y = 4 . . . . . this equation is not what you have written

<em>Additional comment</em>

The second equation suffers from a typo, so your answer may vary.

We can take the two points given and plug them into the slope formula.

\sf~m=\dfrac{y_2-y_1}{x_2-x_1}

(-3, 3), (1, -5)
x1  y1  x2 y2

\sf~m=\dfrac{-5-3}{1-(-3)}

Subtract:

\sf~m=\dfrac{-8}{4}

Divide:

Answer:

The value of <em>x</em> is 0.624.

Property used: Symmetric property of equality

Step-by-step explanation:

The expression to be solved is:

f (x) = 2.5\cdot (6.25x+0.5)-11

Compute the solution as follows:

f (x) = 2.5\cdot (6.25x+0.5)-11

       =(2.5\times 6.25\ x)+(2.5\times 0.5)-11

∵ Distributive property (a (b + c) = ab + ac)

       =15.625x+1.25-11\\=15.625x-9.75

Substitute equation equal to 0 to compute the value of <em>x</em> as follows:

0=15.625x-9.75\\\\15.625x=9.75\\\\

∵ Symmetric property of equality if a = b then b = a

x=\frac{9.75}{15.625}\\\\x=0.624

Thus, the value of <em>x</em> is 0.624.
