(a) Write the point–slope form of a function that has a slope of 3- 5 and passes through the point (6,1).
(b) Algebraically manipulate your answer in part a to produce the slope– intercept form of the function that has a slope of 3 - 5 and passes through the point (6,1).

Answers

The question illustrates linear equation

The equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]The equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

The given parameters are:

[tex]\mathbf{m = \frac 35}[/tex] --- the slope

[tex]\mathbf{(x_1,y_1) = (6,1)}[/tex] -- the point it passes through

(a) The equation in point slope form

This is represented as:

[tex]\mathbf{ y - y_1 = m(x - x_1)}[/tex]

Substitute known values

[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

So, the equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

(a) The equation in slope intercept form

In (a), we have:

[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

Open brackets

[tex]\mathbf{ y - 1 = \frac 35x - \frac{18}5}[/tex]

Add 1 to both sides

[tex]\mathbf{ y = \frac 35x - \frac{18}5 + 1}[/tex]

Take LCM

[tex]\mathbf{ y = \frac 35x + \frac{-18 + 5}5}[/tex]

[tex]\mathbf{ y = \frac 35x + \frac{-13}5}[/tex]

[tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

Hence, the equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

Answers

Answer:

3.75

Step-by-step explanation:

Angle 2 and angle 3 are supplementary angles, so we can add them together and put it equal to 180°

Equation:

30x + 14 + 10x + 16 = 180

Combine like terms:

40x + 30 = 180

Subtract 30 from both sides:

40x = 150

Divide both sides by 40:

3.75

Check:

Take the orginal equation:

30x + 14 + 10x + 16 = 180

Plug in for x:

30(3.75) + 14 + 10(3.75) + 16 = 180

Solve:

112.5 + 14 + 37.5 + 16 = 180

180 = 180 ✅

The pizza costs $9.75 each you buy 3 pizzas and eat 1/5.  How much pizza did you eat? how much pizza is left over? helpp

Answers

Answer:

1/5 pizzas; 2 4/5 pizzas

Step-by-step explanation:

the cost is unneeded information

if you bought 3 pizzas but only ate 1/5 of a pizza you subtract them

3 - 1/5 is 2 4/5 or 2.8

you ate 1/5 of the pizzas and have 2 4/5 left

Step-by-step explanation:

You bought 3 pizzas.

You ate 1/5. It can be as 1/5 of one pizza or 1/5 of all pizzas.

The first case:

3  - 1/5 = 2 4/5 pizzas left

The second case:

3 - 1/5*3 = 3 - 3/5 = 2 2/5 pizzas left

Answers

Answer:

(2.5, 0) and (0, - 5)

Step-by-step explanation:

The line is:

4x - 2y = 10

The x- intercept is the value of x, when y = 0:

4x - 2*0 = 104x = 10x = 2.5

The y- intercept is the value of y, when x = 0:

4*0 - 2y = 10- 2y = 10y = - 5

4x-2y=102y=4x-10

x intercept
