The equation that represents the line  that is perpendicular to the graph of 4x + 3y = 9 and passes through (-2,3) is

[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]

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

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.

The population in the next 20 years would be 2653 people. The result is obtained by the equation of estimating the future population.

The future population can be estimated by the following equation:

P = P₀ × (1 + i)ⁿ

Where

If the recent population is 1000 people and the growth rate is 5% per year, what would the population be in the next 20 years?

The population in the next 20 years would be

P = P₀ × (1 + i)ⁿ

P = 1000 × (1 + 0.05)²⁰

P = 1000 × (1.05)²⁰

P = 1000 × 2.6533

P = 2653 people

Hence, the population in the next 20 years would be 2653 people.

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)

Step-by-step explanation:

false.

QR and ES are line segments.

a ratio between them is about their lengths, not about their position.

so, no, the given ratio has nothing to do with the coordinate itself.

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.

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.

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

What are the trigonometric identities?

All trigonometric identities are based on the six trigonometric ratios. Sine, cosine, tangent, cosecant, secant, and cotangent are the values. All of these trigonometric ratios are defined using the sides of a right triangle, such as an adjacent side, opposite side, and hypotenuse side.

Let's consider,

x = opposite side of an angle of the triangle.

y = adjustant side of an angle of the triangle.

z = hypotenuse of the triangle.

θ = angle of the triangle.
