y=1/2(x+4)^2-12 in standard form

Answer:

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

Answer:

32.3x + 136.85y

Step-by-step explanation:

Let's take it as,

→ z = 100%

Forming the equation,

→ z + 15% = 38x + 161y

Now the value of z will be,

→ z + 15% = 38x + 161y

→ z = 38x + 161y - (1 - (15/100))

→ z = (38x + 161y) × (1 - 0.15)

→ z = (38x + 161y) × (0.85)

→ [ z = 32.3x + 136.85y ]

Hence, the answer is above.

As their measure of angles are not the same with respect to the positive x-axis they are not parallel.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know two lines are parallel if their slope is equal.

Given are two lines m and n.

For line m, slope(m) is m/2 = (5x + 3)° where x = 14.

Slope(m) is, m/2 = (5·14 + 3)°.

m/2 = 73°.

m = 146°.

For line n, slope(m) is, m/3 = (8x - 5)° where x = 14.

m/3 = 107°.

m = 321°.

As their measure of an angle is not the same with respect to the positive x-axis these two lines are not parallel.

According to the solving the co-ordinate mid-point D is (-4,0).

A point on a line which bisects the same line is a mid point. It divides the line in two equal halves.

The mid-point is equidistant from both the ends of the given line.

Middle point formula in coordinate geometry

M={(x1+x2)/2,(y1+y2)/2}

We need to find the coordinates of mid-point D of line AB, where

A is (-6x,4y)

B is (-2x,-4y)

By using Mid-point formula for coordinate D, we get

   x=-6+(-2)/2

⇒ x=-6-2/2

⇒x=-8/2

⇒x=-4

And y coordinate

y=4+(-4)/2

⇒y=4-4/2

⇒y=0/2

⇒y=0

The coordinates of mid-point D of line AB is (-4,0)

Hence, D is (-4,0)

The formula for the perimeter of a rectangle in terms of the width w is w=(P-2l)/2.

Given that, the formula for the perimeter of a rectangle is P=2(l+w).

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Here, the perimeter is  P=2(l+w)

⇒ P=2l+2w

⇒ P-2l=2w

Answer: 25% of 12 is 3

Step-by-step explanation:

Since there 25% is 1/4 of 100%, you'd need to divide.

There are 12 pints of berries.

If 1/2 of 25% is 6 since [tex]2 \sqrt{12}=6[/tex], you can say that the percentage would be 2/4.

Now, divide 12 by 4: [tex]4\sqrt{12}=3[/tex]

3 in this case would be the 1/4 and the 1/4 is substituting 25%

So there are 3 pints of blueberries.

Answer:

[tex] \huge{ \bold{f(g(x)) = 4x + 4}} \\ \\ \huge{ \bold{g(f(x)) = 4x - 5}}[/tex]

Step-by-step explanation:

f(x) = 4x-8

g(x)=x+3

In order to find f(g(x)) you substitute g(x) into f(x) that's where ever you find x in f(x) you replace it with g(x) and solve

We have

[tex]f(g(x)) = 4(x + 3) - 8 \\ = 4x + 12 - 8 \\ = 4x + 4[/tex]

In order to find g(f(x)) you substitute f(x) into g(x) that's where ever you find x in g(x) you replace it with f(x) and solve

We have

[tex]g(f(x)) = (4x -8) + 3 \\ = 4x - 8 + 3 \\ = 4x - 5[/tex]

If Angle E and angle F are supplementary to each other, and (∠E = 62°), then the measure of ∠F will be 118°.

As per the question statement, Angle E and angle F are supplementary to each other, and (∠E = 62°),

Then we are required to calculate the measure of ∠F.

To answer this question, first we need to understand the concept of supplementary angles. "Two angles are said to be supplementary to each other, if their sum is equal to 180°".

That, if Angle E and angle F are supplementary to each other, then

[(∠E + ∠F) = 180°],

Or, [(62° + ∠F) = 180°]...[∵(∠E = 62°), given]

Or, [∠F = (180 - 62)°]

Or, (∠F = 118°)

[tex]y = \frac{3}{4}x+\frac{9}{2}[/tex]

Let us revise some rules

1.   The product of the slopes of the perpendicular line is -1, that means if the slope of one line is m, then the slope of the other is [tex]\frac{-1}{m}[/tex]

2.  The slope of a line whose equation is ax + by = c is [tex]m = \frac{-a}{b}[/tex], where a is the coefficient of x and b is the coefficient of y

The equation of the given line is 4x + 3y = 9

[tex]m = \frac{-a}{b}[/tex]

whereas a is the coefficient of x and b is the coefficient of y

Therefore the coefficient of x = 4 and the coefficient of y = 3

a = 4 and b = 3

[tex]m = \frac{-a}{b}[/tex]

The slope of the perpendicular line to the given line is [tex]\frac{-1}{m}[/tex]

That means reciprocal the fraction and change its sign

The slope of the perpendicular line = [tex]\frac{3}{4}[/tex]

The form of the equation is y = mx + b

- Substitute m by [tex]\frac{3}{4}[/tex]

y = [tex]\frac{3}{4}[/tex] x + b

To find b substitute x and y in the equation by the coordinates

of a point on the line

The perpendicular line passes through point (-2 , 3)

x = -2 and y = 3

3 = [tex]\frac{3}{4}[/tex](-2) + b

3 = [tex]\frac{-3}{2}[/tex]+ b

Add to both sides

[tex]\frac{9}{2}[/tex] = b

y = [tex]\frac{3}{4}[/tex] x + [tex]\frac{9}{2}[/tex]

The equation that represents the line  that is perpendicular to graph of 4x + 3y = 9 and passes through (-2,3) is y = [tex]\frac{3}{4}[/tex] x + [tex]\frac{9}{2}[/tex]

The change in the tram's elevation for each second = The total distance that tram moved downwards / Total time taken

Substitute the values in the equation

The change in the tram's elevation for each second = 35 /7
