Heyo! I need some help, please. What is the x coordinate if (x, 17) is on a line that passes through the points (1, 2) and (-1,

expeople1 [14]

Answer:

x = 4

Step-by-step explanation:

The line with points (1,2) and (-1,-8). Work out its equation.

y = mx + b

The slope is:

m = (-8 - 2)/(-1 - 1) = -10/-2 = 5

To find the y intercept, substitute x and y-xoordinates of point (1,2):

2 = 5(1) + b
b = 2 - 5
b = -3

The line is:

y = 5x - 3

Point (x, 17), substitute y-coordinate and solve for x

17 = 5x - 3
5x = 17 + 3
5x = 20
x = 20/5
x = 4

A drawing has a scale 1/4 in: 12ft. How long is 8ft?

allochka39001 [22]

If you use a proportion, you'll get:

$\frac{0.25}{12} = \frac{x}{8}$

Then, you use cross products:

$12x=0.25(8) \\ 12x=2$

Then, you algebraically solve x:

$12x=2 \\ \frac{12x}{12} = \frac{2}{12} \\ x= \frac{5}{3}$

The answer is 5/3 inches , or 1 5/13 inches, or 1.6 repeating.

How do I write the sum of 6x and 2x is at least 39 ?

tatiyna

<h2>Put x = $\dfrac{39}{8}$ I write the sum of 6x and 2x is at least 39 .</h2>

Step-by-step explanation:

We have,,

6x and 2x

To find, the value of x = ?

According to question,

The sum of 6x and 2x is at least 39

∴ 6x + 2x = 39

⇒ 8x = 39

⇒ x = $\dfrac{39}{8}$

∴ The value of x = $\dfrac{39}{8}$

Thus, put x = $\dfrac{39}{8}$ I write the sum of 6x and 2x is at least 39 .
