Answer:c

Step-by-step explanation:

Answer:

The sorted steps are;

1) Write the equations: 10·x + 8·y = 472 and 9·x + 8·y = 456

2) Multiply to get one variable to eliminate: -90·x - 72·y = -4248 and 90·x + 80·y = 4560

3) Eliminate x's: 8·y = 312

4) Solve for y: y = 39 (39 buses)

5)Plug back in to find x: 10·x + 8·(39) = 472

6) Solve for x: x = 16 (16 vans)

Step-by-step explanation:

Let x = The number of students in each van and y = The number of students in each bus

We have;

For High School A;

10·x + 8·y = 472...(1)

For High School B;

9·x + 8·y = 456...(2)

Multiply equation (1) by (-9) and equation (2) by 10 to get

(10·x + 8·y) × (-9) = 472 × (-9)

-90·x -72·y = -4,248...(3)

9·x + 8·y × (10)= 456 × (10)

90·x + 80·y = 4,560...(4)

Add equation (3) to (4) gives;

-90·x -72·y + 90·x + 80·y = -4,248 + 4,560

90·x - 90·x -72·y + 80·y = -4,248 + 4,560

8·y = 312

y = 312/8 = 39

y = 39

Substituting the value of y in equation (1), gives;

10·x + 8·y = 10·x + 8 × 39 = 472

10·x + 312 = 472

10·x  = 472 - 312 = 160

10·x  = 160

x = 160/10 = 16

x = 16

The number of students in each van = x = 16 students

The number of students in each bus = y = 39 students.

Step-by-step explanation: The total number of city council is 80 and 20/80 is 1/4

Answer:

Use the distance formula;

d = SQR[(x2 - x1)^2 + (y2 - y1)^2]

d = 10 and (x2, y2) = (-4, 5)

10 = SQR[(-4 - x1)^2 + (5 - y1)^2]

Answer:She incorrectly factored out the value of a.

Step-by-step explanation:

In solving a quadratic equation by completing the square method, the value a is not factored out. Rather, the steps involved are:

Divide through all the terms by a

Move the term c/a to the right had side

Complete the square on both sides using the value of b/2

Obtain the values of x

Answer: B. She subtracted the wrong value to maintain balance after completing the square.

Answer:

Perimeter of rectangle = 728 cm

Step-by-step explanation:

Length :  breadth = 15 : 11

Length = 15x

Breadth = 11x

15x - 11x = 56 cm

         4x = 56

           x = 56/4

           x = 14

Length = 15 *14 = 210 cm

Breadth = 11 * 14 = 154 cm

Perimeter of rectangle = 2 * ( length + breadth)

                                     = 2 *(210 + 154)

                                     = 2 * 364

                                      = 728 cm

y = 8x

Where x = number of minutes used

y = total cost for x minutes

Cost equation for Tryus telephone company :

y = connection fee + (fee per minute * number of minutes)

y = 42 + (2x)

Where x = number of minutes used

y = total cost for x minutes

Answer:

y= - 1/4x

Step-by-step explanation:

The equation of the line passing through that point with the required slope is y=2x+3.

The slope of a line is the change in the y-coordinate relative to the change in the x-coordinate. The net change in the y-coordinate is indicated by Δy and the net change in the x-coordinate by Δx. Thus, the change in y-coordinate with respect to change in x-coordinate is given by: m = change in y/change in x = Δy/Δx Where "m" is the slope of the line.  The slope of a straight line can also be represented by the formula  tan θ = Δy/Δx  So, tan θ is the slope of a straight line. In general, the slope of a line indicates its steepness and direction.

Given:

The angle of slope of a line between two points (x1,y1) and (x2,y2) can be easily determined by finding the difference in the coordinates of the points. The slope is usually indicated by the letter "m".

The slope of a line passing through points (x1,y1)and(x2,y2) is given by

m=(y2−y1)/(x2−x1)

The slope ([tex]m^p)[/tex] of a line perpendicular to a line with slope ([tex]m^p)[/tex] is =−1/m because the product of the slopes of two perpendicular lines is -1, except in the pathological case where the lines are parallel to the x and y axis.

slope  m  of a line, and the coordinates of a known point  (x1,y1)  it is simple to plug them into the point-slope formula for a line to determine the equation for that line.

y=mx +b

y1=mx1+b

solve for  b

Going through those steps:

(x1,y1)=(-6, 8)

(x2,y2)=(10,0)

m=(0-8)(10-(-6))=-0.5

[tex]m^p[/tex]=−1/-0.5= 2

our known point is (−4,−5)

−5=2(−4)+b

-5 = -8+b

b = 3

Therefore, the equation of the line passing through that point with the required slope is y=2x+3.
