my hw write find an equation of the line passing through (-2,3) and (4,-5) I have to write the equation in slope-intercept form
Viefleur [7K]

Answer:

The line passing through the given points is:

y=-\frac{4}{3}x+\frac{1}{3}

in its slope-intercept form

Step-by-step explanation:

Start by finding the slope of the segment that joins the two given points using the slope formula:

slope=\frac{y_2-y_1}{x_2-x_1}

which for our case renders:

slope=\frac{3-(-5)}{-2-4}=\frac{8}{-6} =-\frac{4}{3}

Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:

y=-\frac{4}{3} x+b\\3=-\frac{4}{3} (-2)+b\\3=\frac{8}{3}+b\\b=3-\frac{8}{3} \\b=\frac{9-8}{3} \\b=\frac{1}{3}

Therefore, the equation of the line becomes:

y=-\frac{4}{3}x+\frac{1}{3}

Please just answer this and explain how to solve...i’m not grasping the work :/
OverLord2011 [107]

\bf Step-by-step~explanation:

We are given that BA is perpendicular to BD, so that must mean that <em>m∠ABD </em>is a right angle, or 90º. This means: (8x - 10) + (4x + 52) = 90º, since both of the angles add up to become a right angle. We have to solve for x in order to find <em>m∠CBD.</em>

<em />

<u>PART 1</u>

<em />

<em />\bf Step~1:<em />

Equation: (8x - 10) + (4x + 52) = 90

Let's add the like values together first.

\bf 8x+4x=12x\\-10+52 = 42

\bf 12x+42=90

\bf Step~2:

Let's subtract 42 from both sides of the equation to isolate the variable we are solving for, x. Our goal is to isolate it completely to get a value that is equal to x.

\bf12x+42(-42)=90(=42)\\12x=48

\bf Step~3:

Divide both sides by 12 to get our final answer for x.

\bf\frac{12x}{12} =x\\\\\frac{48}{12}= 4\\\\x=4

<u>PART 2</u>

<u></u>

Now that we have x, we simply plug it into our equation for <em>m∠CBD. </em>

<em />

<em />\bf Step~1:<em />

\bf4x+52\\4(4)+52

\bf Step~2:

Multiply 4 and add 52.

\bf 4*4=16\\16+52=68

\large\boxed{\bf Our~final~answer: mCBD=68}

There are 18 cupcakes.How many three fourths size servings can you make?
kramer

Answer:

24 servings

Step-by-step explanation:

A serving is 3/4 of a cupcake and you have 18 cupcakes.

Logically, you have more than 18 servings. Therefore the answer makes sense.

Divide the total number of cupcakes by the size of one serving.

18 cupcakes ÷ (3/4) = 24 servings

You can make 24 servings.
