2. n = 26

3. v = 38

4. d = 6

Step-by-step explanation:

5v = 95

÷5    ÷5

v = 19

--------------------

n - 19 = 7

   +19   +19

n = 26

-----------------------

v

/    =  19

v

/        = 19(2)

2(2)

v = 38

-----------------------------

4d = 24

÷4    ÷4

d = 6

I hope this helps!

Answer:

h = 3.6

Step-by-step explanation:

This is just substituting in for variables and solving for x. The hard part is knowing the formula.

R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.

Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.

(8.1) = h(((1) + (3.5)) / 2)

= h((4.5) / 2)

= h(2.25)

8.1/2.25 = h

3.6 = h

Using the given information we found that the equation of the parabola is:

y = (-4/9)*(x - 3)^2 + 5

And its graph is below.

For a parabola with vertex (h, k), the equation is:

y = a*(x - h)^2 + k

Here the vertex is (3, 5), so the equation is:

y = a*(x - 3)^2 + 5

And the y-intercept is y = 1, this means that:

1 = a*(0 - 3)^2 + 5

1 = a*9 + 5

1 - 5 = a*9

-4/9 = a

So the parabola is:

y = (-4/9)*(x - 3)^2 + 5

And its graph is below.

Step-by-step explanation:

y = mx + c

is this form

-1/2x + y = 10

we need to get y by its self

to do that move -1/2x to the other side

do u know how to do that

Answer:

 Slope = 1.000/2.000 = 0.500

 x-intercept = 20/-1 = -20.00000

 y-intercept = 20/2 = 10

Step-by-Step Explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-1/2*x+y-(10)=0  <----- given linear equation

STEP 1:

Simplify 1/2

Equation at the end of step 1:

((0 - (1/2 • x)) +  y) -  10  = 0

STEP 2 : Rewriting the whole as an Equivalent Fraction

Adding a whole to a fraction

Rewrite the whole as a fraction using  2  as the denominator :

y = y/1  = y · 2/2

Equivalent fraction :

Common denominator :

Adding fractions that have a common denominator :

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-x+y• 2 /2 = 2y-x/2

Equation at the end of step 2:

(2y-x)/2-10=0

Step 3:

Rewriting the whole as an Equivalent Fraction :

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  2  as the denominator :

10=10/1=10 * 2/2

Adding fractions that have a common denominator :

Adding up the two equivalent fractions

(2y-x)-(10*2)/2=-x+2y-20/2

Step 4:

Pulling out like terms :

Pull out like factors :

-x + 2y - 20  =   -1 • (x - 2y + 20)

Equation at the end of step 4:

-x+2y-20/2=0

Step 5: When a fraction equals zero :

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

-x+2y=20/2 *2=0*2

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -x+2y-20  = 0

Equation of a Straight Line

Solve   -x+2y-20  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  -x+2y-20  = 0 and calculate its properties

Graph of a Straight Line : PICTURE

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000

 y-intercept = 20/2  =  10

Calculate the X-Intercept :

When y = 0 the value of x is 20/-1 Our line therefore "cuts" the x axis at x=-20.00000

x-intercept = 20/-1  = -20.00000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is 11.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 11.000 - 10.000 = 1.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  1.000/2.000 =  0.500

Geometric figure: Straight Line

 Slope = 1.000/2.000 = 0.500

 x-intercept = 20/-1 = -20.00000

 y-intercept = 20/2 = 10

Step-by-step explanation:

Answer:is the same number

Step-by-step explanation:289 because it’s a square all squares have same side

Basically all you need to show is –(p-q)=(-p)+q. (1)

Since 0 = (p-q) + (-(p-q)) (additive inverse), we get –p = -q +(-(p-q)). Now substitute for (–p) in (1).

Then m+q-n-p=(m+q)-(n+p) follows. (since -n-p+(n+p) = 0 implies -n-p = -(n+p) (additive inverse))

so technically all u need to show is –(p-q)=(-p)+q. Hope this helps!!
