Solve The Equation Below

Flura [38]

Answer:

Step-by-step explanation:

10 + sqrt(y) = 14

Subtract 10 from each side

10 -10+ sqrt(y) = 14-10

sqrt(y) = 4

Square each side

(sqrt(y)) ^2 = 4^2

y = 16

What is the solution to the open sentence 18 = c + 6?

sveticcg [70]

This is very simple, all you have to do is subtract 18 and 6 and that would be 12, and now we have 12 as a POSSIBLE answer, lets check our work to be 100% correct so now try to add 12 and 6 and we get 18, so yay it made the equation true and since its true its right so that's the answer.

Answer: c = 12 so 18 = 12 + 6 is true.

Consider the line y=5x -3 Find the equation of the line that is patellar to this line and passes through the point (-8, -3) Cons

Lynna [10]

Answer:

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: $y = 5x+37$

Step-by-step explanation:

Given equation of line is:

$y=5x-3$

The general form of equation of line in slope-intercept form is written as:

$y = mx+b$

Here m(co-efficient of x) is the slope of the line and b is the y-intercept.

Comparing the given equation with the general form we get

m = 5

Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.

Let m1 be the slope of required line parallel to y=5x-3

Then m1=5

Putting in general form

$y = m_1x+b$

$y=5x+b$

To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.

The point is (-8,-3)

$-3 = 5(-8)+b\\-3 = -40+b\\b = -3+40\\b = 37$

Putting the value of b and m1, we get

$y = 5x+37$

Hence,

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: $y = 5x+37$

20 POINTS!!!!!!

Crazy boy [7]

You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)

Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
