Answer:

Option A

Step-by-step explanation:

The equation of line is

Solution:

Given that line passes through the point (4, –6) and has a slope of Negative three-fourths

Given point is (x, y) = (4, -6)

The equation of line passing through point (x, y) and slope "m" is given as:

y = mx + c ----- eqn 1

Where "m" is the slope of line and "c" is the y - intercept

Substitute (x, y) = (4, -6) and  in eqn 1

The required equation of line is given as:

Thus the equation of line is found

450mL : 1L   =    9 : 20

Step-by-step explanation:

recall that 1L = 1000 mL,

450 mL : 1L  can be expressed as

450mL : 1000 mL   (we can simplify this with the following steps)

450 : 1000     (divide both sides by 10)

45 : 100  (divide both sides by 5)

9 : 20  (answer)

Answer:

B=-2

Step-by-step explanation:

Answer:   C. y=4x

Step-by-step explanation:

Proportional relationship means that the line will be going through the origin, meaning that if the x coordinate is 0, then y has to also equal to 0. Also another way to determine a proportional relationship is by identifying the slope and y intercept. If the line has a y-intercept then it is not proportional because it will not be going through the origin.

y = 4x  Input 0  for x and y.

0 = 4(0)  

0 = 0  

This makes the statement true because if x is 0 then y is also 0.

-I haven't done this, but I have copied and pasted from another question and answer from the user syed514:

Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.

If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.

Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.

Solving for the coordinates gives x2 = 10, y2 = 13

Answer:

[tex]y=-4x^{2} +7x+6\\[/tex]

Step-by-step explanation:

[tex]y=ax^{2} +bx+c\\[/tex]

Points are (1,9), (2,4), and (4,-30).

[tex]\\9=a+b+c\\4=4a+2b+c\\-30=16a+4b+c\\[/tex]

Subtract the first from the second.

-5 = 3a+b

Subtract 4 times the second from the third.

-34=12a+2b

-14=-2b

b=7

a=-4

c=6

17*40+17*1.5*6.25=839.38

Answer:

y = [tex]\frac{1}{2}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]

The line crosses the y- axis at (0, 1) ⇒ c = 1 , then

y = [tex]\frac{1}{2}[/tex] x + 1 ← equation of perpendicular line

Answer:

11

Step-by-step explanation:

The total number of marbles John gets is 22 and this can be determined by forming the linear equation with help of the given data.

Given :

The following steps can be used in order to determine the total number of marbles john gets:

Step 1 - Let the total number of marbles John have to be 'x', let the total number of marbles David have to be 'y', and let the total number of marbles Paul have to be 'z'.

Step 2 - So, the linear equation that represents the total number of marbles is:

x + y + z = 38    --- (1)

Step 3 - According to the given data, John gets twice as many as David, that is:

x = 2y  --- (2)

Step 4 - According to the given data, Paul gets only 5 marbles, that is:

z = 5  --- (3)

Step 5 - Substitute the value of x and z in equation (1).

2y + y + 5 = 38

Simplify the above equation.

3y + 5 = 38

3y = 33

y = 11

Step 6 - Substitute the value of y in equation (2).

x = 2(11)

x = 22

So, the total number of marbles John gets is 22.
