Flauer [41]

Okay, so I'm assuming you want to know the intersection?

-5 = -1/2x - 2

-3 = -1/2x

1/2x = 3

x = 6

Find the equation of the line through (6,4) and (-3,-8)
alexdok [17]

Answer:

y = 4/3x - 4

Step-by-step explanation:

to find the equation of a line with 2 points, we use the slope formula which is:

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

we will use (6,4) as x_1[tex] and [tex]y_1 and we will use (-3,-8) as x_2[tex] and [tex]y_2. we plug this into the slope formula:

\frac{-8-4}{-3-6}

-8 - 4 = -12

-3 - 6 = -9

the slope is \frac{-12}{-9}

but we can simplify this further by dividing the fraction by -3

-12 / -3 = 4

-9 / -3 = 3

the simplified version of the slope is \frac{4}{3}

we can write this in slope-intercept form which is y =mx + b, with b being the y intercept and m being the slope

y = 4/3x + b <--- we need to solve for <em>b</em> in order to find the y intercept, so substitute x & y for a point on the line, we can use any point we are given, but for this example i will use (6,4)

4 = 4/3(6) + b < multiply 4/3 x 6

4 = 8 + b < subtract 8 from both sides

-4 = b

our y intercept would be (0,-4)

the equation looks like the following:

y = 4/3x - 4, which is our answer

When f(x) = 2x 2 + 3, find f(-3).<br> -15<br> 21<br> 39
notsponge [240]

Answer:

21

Step-by-step explanation:

f(x) = 2x^2 + 3

f(-3) = 2(-3)^2 + 3

f(-3) = 2(9) + 3

f(-3) = 18 + 3

f(-3) = 21

Today Ian wants to run less then 7/12 miles. Write a fraction with a denominator of 4 to represent a distance that is less then
dezoksy [38]
2/4 is one you could put because 2/4 = 1/2 = 6/12, and 6/12 is less than 7/12.

Glad I could help, and good luck!

For the function f(x)=3x−4 , what is the ordered pair for the point on the graph when x=6 ? Show work for full credit.
Ksivusya [100]

To find the ordered pair, we simply set the x value equal to 6.

We already know the first coordinate will be 6.

f(6) = 3(6) - 4

f(6) = 18 - 4

f(6) = 14

<h3><u>The y value is 14, and so our coordinate pair is (6, 14)</u></h3>
