Solve the absolute value equation |x| − 2 = 5 to find the distance Mary can walk forward, x, in 5 seconds.

Alisiya [41]

Answer:

x = 7 m and x = −7 m

Step-by-step explanation:

Its a modulus problem

concept

|x| = x when x>=0

|x| = -x when x < 0

____________________________________

Now given

|x| − 2 = 5

adding 2 both sides

|x| − 2 + 2 = 5 + 2

|x| = 7

now

x = 7 when x >= 0

x = -7 when x<0

Thus, correct answer is x = 7 m and x = −7 m

All eleven letters in the word GRASSHOPPER are put in a box. What is the probability of drawing a consonant from the box?

Anna007 [38]

R, h, g, s, and p are all constants, so that would be 8/11, or 72% of a chance of getting a consonant.

I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)

Please help i dont know how to do this

Hello once again!

When you see a question like this, you need to find the equation of the straight line.

The formular used is y = mx + c
Where
m = slope
c = constant

First find the slope, since it's a straight line, any 2 coordinates can be used.

$m = { \frac{y_1 - y_2}{x_1-x_2} } \\ m= { \frac{16 - (- 8)}{-2 - 2} } \\ m= { \frac{24}{-4} } \\ m = -6$

Now we need to substitude in the slope, and one of the coordinate you used to find the slope, to the formular to find the constant.

In this case i'm using the coordinate
(-2, 16)

y = mx + c
16 = -6(-2) + c
16 = 12 + c
c = 4

∴ The equation of the line is y = -6x + 4

The next step is to simply substitude in the x = 8 to the equation to find y.

y = -6(8) + 4
y = -48 + 4
y = -44
