The equation of line -4x - 3y = 8 is perpendicular to the given line of the equation which is the correct answer would be option (C).

What are the perpendicular lines?

Perpendicular lines are two lines that cross one other and create a 90-degree angle.

The equation of the line below which is given in the question

4x - 3y = 8

We have to determine which is perpendicular to the given equation of the line

First, we need to find the slope of the given equation.

4x - 3y = 8

- 3y = - 4x + 8

Divided by -3 into both sides of the above equation,

y = (- 4/-3)x + 8/(-3)

y = (4/3)x - 8/3

Comparing the above equation with the standard form of line y = mx + b

Here m is the slope of the line,  in this case, m = 4/3.

As per option (C),

- 3y = 8 + 4x

Divided by -3 into both sides of the above equation,

y = - 4/3x - 8/3

Here the slope of this line is - 4/3

Therefore, the equation of line -4x - 3y = 8 is perpendicular to the given line of the equation.

Hence, the correct answer would be option (C).

Find the zeroes of the polynomial and verify the relationship between the zeroes and coefficients

1. 6x^2 - 3 - 7x
2. 3x^2 - x - 4

Answers

Answer: Step-by-step explanation:

1. Given  f(x) = 6x2 – 7x – 3

To find the zeros

Let us put f(x) = 0

⇒ 6x2 – 7x – 3 = 0

⇒ 6x2 – 9x + 2x – 3 = 0

⇒ 3x(2x – 3) + 1(2x – 3) = 0

⇒ (2x – 3)(3x + 1) = 0

⇒ 2x – 3 = 0 Or 3x + 1 = 0

x = 3/2                      x = -1/3

It gives us 2 zeros, for x = 3/2 and x = -1/3  

Hence, the zeros of the quadratic equation are 3/2 and -1/3.

Now, for verification

Sum of zeros = – coefficient of x / coefficient of x2

3/2 + (-1/3) = – (-7) / 6 7/6 = 7/6  

Product of roots = constant / coefficient of x2

3/2 x (-1/3) = (-3) / 6 -1/2 = -1/2

Therefore, the relationship between zeros and their coefficients is verified.

2.Let f(x) = 3x2 ˗ x ˗ 4 = 0

3x2 ˗ 4x + 3x ˗ 4  = 0

⇒ x(3x ˗ 4) + 1 (3x ˗ 4)  = 0

⇒  (3x ˗ 4) (x + 1) = 0

To find the zeroes

(3x ˗ 4) = 0 or (x + 1) = 0

x = 4/3 or x=-1

So, the zeroes of f(x) are 4/3 and x=-1

Again, Sum of zeroes = 4/3 + (-1) = 1/3 = -b/a =

=(-Coefficient of x)/(Cofficient of x2)

Product of zeroes = 4/3  x (-1) = -4/3 = c/a=

= Constant term / Coefficient of x2

Therefore, the relationship between zeros

Step-by-step explanation:

3x - 4y = 12

Subtract 3x from each side

3x - 4y -3x =-3x+ 12

-4y = -3x+12

Divide by -4

-4y/-4 = -3x/-4 +12/-4

y = 3/4x -3

Answer

The value of y is 3/4x-3.

Explanation

Rearrange the equation to get y on one side of the equation.

3x-4y=12

-4y=12-3x

y=-3+3/4x

y=3/4x-3

There were some adults and children at the part. For every 3 adults, there were 11 children. There were 32 more children than adults. How many adults were at the party

Answers

Answer:

12

Step-by-step explanation:

Ratio of adults to children = 3 : 11

Let

x = number of adults at the party

32 + x = number of children at the party

Ratio of adults to children = x : (32 + x

Equate both ratios

3 : 11 = x : 32 + x

3/11 = x : (32 + x)

Cross product

3 * (32 + x) = 11 * x

96 + 3x = 11x

96 = 11x - 3x

96 = 8x

x = 96/8

x = 12

x = number of adults at the party = 12

2. the slope is 3

3. -4/3

4. $1.50 per book

5. -2

Step-by-step explanation:

1. the table itself says it for x=0. f(x) for x=0 is 6.

2. as explained do often already. the slope is the ratio of y/x showing how many units y changes, when x changes a unit or another surviving number of units.

the table shows when x increases by 1 unit, y increases by 3 units. so, the slow is 3/1 or simply 3.

3. again slope (see 2.).

going from M to N x increases by 4 units (from 1 to 5), and y decreases by 3 units (from 3 to 0).

so, the slope is y changes / x change = 4/-3 or simply -4/3

4. rate of change is

(f(a) - f(b)) / (a - b)

e.g.

(275 - 50) / (250 - 100) = 225 / 150 = 1.5

5. again very simple. which of the provided answer options appears in the f(x) column ?

Step-by-step explanation:

This is because if you add all the angles in a triangle they should add to 180. 77+31=108

180-108=72

Answer:

72

Step-by-step explanation:

We know that , the sum of interior angles of any shape can be measured using the formula: (n-2)× 180; where, n is the number of sides in the shape.

Here, the figure is a triangle. Therefore,

n= 3

(3-2)* 180=180°

Hence, the sum of all angles in this figure is 180.

That is, 77+31+x= 180°

108+x=180°

x= 180-108= 72°

Therefore, x= 72°

The x-intercepts of a parabola are the points where the parabola intersect the x-axis (horizontal axis). Therefore, the y-value of the x-intercepts are always 0. Since coordinates are written (x, y), we can immediately eliminate answers B and C.

Next, we look at the x-coordinates of where the parabola intersects the x-axis. We can see clearly that the parabola crosses the x-axis at [tex]x=4[/tex] and [tex]x=5[/tex]. Therefore, the x-intercepts of the given parabola are (4, 0) and (5, 0).

The ratio of the measures of the sides of a triangle is 3:4:5. Its perimeter is 48 inches. Find the scale factor as a decimal, and the measure of each side of the triangle.

Answers

Given:

The ratio of the measures of the sides of a triangle is 3:4:5.

Its perimeter is 48 inches.

To find:

The scale factor as a decimal, and the measure of each side of the triangle.

Solution:

Let x be the scale factor. Then the measures of sides of the triangle are 3x, 4x and 5x.

The perimeter of the triangle is 48 inches. It means the sum of all sides of the triangle is 48 inches.

[tex]3x+4x+5x=48[/tex]

[tex]12x=48[/tex]

Divide both sides by 12.

[tex]x=\dfrac{48}{12}[/tex]

[tex]x=4[/tex]

Now, the measures of sides are:

[tex]3x=3(4)[/tex]

[tex]3x=12[/tex]

Similarly,

[tex]4x=4(4)[/tex]

[tex]4x=16[/tex]

And,

[tex]5x=5(4)[/tex]

[tex]5x=20[/tex]

Therefore, the scale factor is 4 and the measures of sides are 12, 16 and 20.

Answer:

The scale factor is 4.

Sides are 12 inches, 16 inches, 20 inches.

Step-by-step explanation:

The ratio is 3 : 4 : 5 and the perimeter is 48 inches.

Let the scale is p.

The length of sides is 3 p , 4 p and 5 p.

So, the perimeter is

3 p + 4 p + 5 p  = 48

12 p = 48

p = 4

So, the scale factor is 4.

Sides are 12 inches, 16 inches, 20 inches.
