Answer:

2 + (-7) = (-5)

Step-by-step explanation:

Correct problem and method of solving, just miscounted!

It should be + (-7) instead of + (-6).

This also changes the answer to (-5) instead of (-4).

Complete the equation of the line through ( 4 , -8 ) and ( 8 , 5 )

irinina [24]

Answer:

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

Step-by-step explanation:

Given:

Let,

point A( x₁ , y₁) ≡ ( 4 ,-8)

point B( x₂ , y₂) ≡ (8 , 5)

To Find:

Equation of Line AB =?

Solution:

Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula

$(y - y_{1} )=(\frac{y_{2}-y_{1} }{x_{2}-x_{1} })\times(x-x_{1}) \\$

Substituting the given values in a above equation we get

$(y-(-8))=(\frac{5-(8)}{8-4})\times (x-4)\\ \\(y+8)=\frac{13}{4}(x-4)\\\\4(y+8)=13(x-4)\\4y+32=13x-52\\13x-4y=84...............\textrm{which is the required equation of the line AB}$

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

What is the value for the missing angle ??

allsm [11]

Answer: 9 inches.
Do the pythagorean theorem to find your answer.
Formula: a^2 + b^2 = c2
12 = b
15 = c
a^2 + 12^2 = 15^2
Simplify the equation
a^2 + 144 = 225
Subtract 144 on both sides.
a^2 = 81
Square root of 81 is 9.

Jolene is making a line graph showing that the cost of grain is proportional to the number of pounds purchased. Jolene will plot

Gelneren [198K]

Answer:

a. $(1,0.25)$

b. $y = 0.25x$

Step-by-step explanation:

Given

The data in the table

Solving (a): The coordinate that represents the unit rate

The unit rate is when its 1 pound

This is so because the unit rate is dollars per pounds.

<em>Hence, the coordinate is </em> $(1,0.25)$ <em></em>

Solving (b): Equation of the graph

First, we calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where:

$(x_1,y_1) = (1,0.25)$

$(x_2,y_2) = (4,1.00)$

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{1.00 - 0.25}{4 - 1}$

$m = \frac{0.75}{3}$

$m = 0.25$

The equation is then calculated as thus:

$y - y_1 = m(x - x_1)$

This gives:

$y - 0.25 = 0.25(x - 1)$

$y - 0.25 = 0.25x - 0.25$

Make y the subject

$y = 0.25x$

<em>Hence, the equation of the graph is: </em> $y = 0.25x$ <em></em>
