<span>8 – (5v + 3) = 5v – 5
8 - 5v - 3 = 5v - 5
5v + 5v = 8 - 3 + 5
10v = 10
v = 1            [has a solution]

3m – 6 = 5m + 7 – m
3m - 6 = 4m + 7
4m - 3m = -6 - 7
m = -13            [has a solution]

3w + 4 – w = 5w – 2(w – 2)
2w + 4 = 5w - 2w + 4 = 3w + 4
3w - 2w = 4 - 4
w = 0                  [has a solution]

7y + 9 = 7y – 6
7y - 7y = -6 - 9
0 = -15                [has no solution]

julsineya [31]

We can express Benjamin's age with x, we can express Luca's age as y.

x-6=2y

So, if x=12

2y=6

y=3

Therfore, Lucas is 3 years old

What are the similarities and differences between the standard form and vertex form of a quadratic equation?
guajiro [1.7K]

Answer and Step-by-step explanation: <u>Standard</u> <u>form</u> of a quadratic equation is expressed as: y=ax²+bx+c, while <u>vertex</u> <u>form</u> is written as:

y=a(x-h)²+k.

The similarities between standard and vertex forms is that they show if the graph of the equation has a <u>minimum</u> (when a>0) or <u>maximum</u> (a<0) and it's easier to determine the y-intercept: for standard, the value of c is the intercept; for vertex, the value k is the intercept.

The advantage of standard form is that you can determine the product and sum of the equation's roots, which is a method to determine them.

The advantages of vertex form are: easier to find the vertex of the graph, which is the pair (h,k) and the axis of symmetry, which is the value of h.

What is the solution to -4|-2x+6| = -24
Arte-miy333 [17]
X = 0.  Since the absolute value of -2x+6 is 2x+6, the absolute value sign acts as () so it would be -4(2x+6) = -24.  That would come out to be           -8x -24 = -24.  Using proper algebra, the answer would come out to be 0

bogdanovich [222]

see explanation below

(1) \frac{1}{5} × \frac{2}{2} = \frac{2}{10} = 0.2

(2) \frac{6}{25} × \frac{4}{4} = \frac{24}{100} = 0.24

(3) 2 \frac{3}{4} = 2 +\frac{75}{100} = 2.75

(4) 3 \frac{9}{10} = 3 + 0.9 = 3.9

(5) 1.25 = 1 \frac{1}{4} = \frac{5}{4}

(6) 3.29 = 3 \frac{29}{100} = \frac{329}{100}

(7) 0.65 = \frac{65}{100} = \frac{13}{20} in simplest form

(8) 5.6 = 5 \frac{6}{10} = 5 \frac{3}{5} = \frac{28}{5}

(9) he is incorrect

\frac{3}{5} × \frac{20}{20} = \frac{60}{100} = 0.6 ≠ 3.5
