Y=3x plus or minus any number that is not 10.

The slope of your function has to stay 3x to be parallel with the function given. Just change the y-intercept (also known as the B value) to a number other than -10.

Answer:

The equation of line parallel to the given equation of line : y = 3x + 4

Step-by-step explanation:

The equation of the line is given to be :

y = 3x - 10

Now, on comparing the given equation of line with the standard equation of line in slope intercept form : y = mx + c

where m is the slope of the line

So, Slope of the given equation of line = 3

Now, Since parallel lines never intersect each other

⇒ The slope of parallel lines are equal to each other

So, The required equation of parallel line is of form : y = 3x + c

Hence, The equation of line parallel to the given equation of line : y = 3x + 4

Solve 3x to the second power -2x-8=0 using an algebraic method

MatroZZZ [7]

Answer:

$x=2\textrm{ or } x=-\frac{4}{3}$

Step-by-step explanation:

Given:

The equation is given as:

$3x^{2}-2x-8=0\\3x^{2}-6x+4x-8=0\\3x(x-2)+4(x-2)=0\\(x-2)(3x+4)=0\\\\x-2=0\textrm{ or }3x+4=0\\x-2+2=0+2 \textrm{ or }3x+4-4=0-4\\x=2\textrm{ or }3x=-4\\x=2\textrm{ or}\\x=-\frac{4}{3}$

Therefore, the possible values of $x$ are 2 and $-\frac{4}{3}$

How many times greater is the value of the 5 in 503 than the value of the 5 in 53?

disa [49]

Answer:

10 times greater

Step-by-step explanation:

Because value of 5 in 503 is 5*100

Then the value of 5 in 53 is 5*10

So then value of 5 in 503 is 10 times greater than the value of 5 in 53

I hope this helps

Seth is trying to find the unit price for a package of blank compact discs on sale at 10 for $5.49. Find his mistake and correct

algol [13]

You haven't shown us his answer or any of his work, so we don't know
whether it was right or wrong, and we have no way to find his mistake
if his work was wrong.

(10 discs) / (5.49 dollars) = (10/5.49) disc/dollar = 1.821 disc per dollar

(5.49 dollars) / (10 discs) = (5.49/10) dollar/disc = 0.549 dollar per disc

Find the vertex and zeros of the following function f(x)=x^2-6x-7

elena-s [515]

Try this solution:

Step-by-step explanation:

1) for zeros of the function: x²-6x-7=0; ⇒ x₁=7; x₂= -1.

2) for the vertex of the function: x₀= -b/2a, where a;b;c - numbers from ax²+bx+c=0 (from x²-6x-7=0).

x₀=6/2=3;

y₀= (4ac-b²)/4a; ⇒ y₀= -16.

It means, the coordinates of the vertex are (3;-16).
