How do you the equation of the line that passes through x-intercept (–8, 0) and undefined slope?

1 answer:

8 0

If the slope is undefined, then your line is a vertical line since vertical lines can have no slope (they don't have any lateral movement). Because it must pass through (- 8, 0), x must = - 8.

Your equation is x = - 8

If f(x) = −3x + 4 and g(x) = 2, solve for the value of x for which f(x) = g(x) is true.Noah started to solve the equation –4.6p

barxatty [35]

Answer:

p = 1.2

Step-by-step explanation:

The given equation is :

–4.6p – 6.3p + 3.9 = –9.18

Combining the like terms,

–4.6p – 6.3p = -9.18 - 3.9

−10.9p = −13.08

⇒ $p=\dfrac{-13.08}{-10.9}\\\\p=1.2$

Hence, the value of p is 1.2

Please help asap i will mark branlist

By looking at the scatterplot, we can identify the ‘trend’, or the general outline of the dots and where they’ll be. Using this, we can predict where a given dot will be in the sequence.

Since the dot for 3 chapters is at 80(roughly) and the dot for 5 chapters is at 140(at the lowest), we can infer that the dot for four chapters will be somewhere in the range of 81-139. From there, we can rule out 140 and 150 as answers, and we can use an inference to pick 120 as the answer.

Hope this helps! :)

Nixon has a square piece of wrapping paper that has a total area of 200 square inches. Which point on the number line below repr

LenaWriter [7]

Answer:

x = 14 inches

Step-by-step explanation:

The area of a square piece of paper is 200 square inches.

We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper. It is shown in the attached figure.

Area of a square = x², x is the side length

$x=\sqrt{A} \\\\x=\sqrt{200} \\\\x=14.142\ \text{inches}$

x = 14 inches

So, the side length of the square is 14 inches. It is shown in point A.
