5 ports Use absolute value to express the distance between -12 and -15 on the number line. |-12 - (-15) = -27

zloy xaker [14]

Answer:

$Distance = 3$

Step-by-step explanation:

Given

-12 and -15

Required

Solve the difference

The question you posted included the solution. However, the solution is incorrect;

The absolute difference is represented as:

$Difference = \vert a - b \vert$

In this case:

$a = -12$

$b = -15$

So, the distance is calculated as:

$Distance = |-12 - (-15)|$

Open bracket

$Distance = |-12 +15|$

$Distance = |3|$

$Distance = 3$

Help?

Kazeer [188]

Remember, h(x) = y and x ...well, x is x...lol

B. h(x) = |x|....subbing in (-1,1)
y = |x|
1 = |-1|...absolute values are positive, even when they say negative
1 = 1 (correct)

Find the value of x. Hint: the chords are congruent/equal (I will give 20 points)

Advocard [28]

$\huge \purple{\tt{Answer:}}$

If the chords are equal , then the measurement of both the chords will also be the same . That means ,

$\sf {6x-7 =35} \\\\\ \implies \sf {6x = 35 +7} \\\\\ \implies \sf {6x=42} \\\\\ \implies \sf{x= {\dfrac{\bcancel {42}^7}{\bcancel{6}}}} \\\\\ \implies \sf{x=7}$

Find the point-slope equation for the line that passes through the points (5, 35) and (-6, -31). Use the first point in your equ

AleksandrR [38]

Answer:

Maya, this is such a common question on here, so i'm very interested in what's difficult about this problem for you. Please comment about this. Below is the answer and how to find it.

Step-by-step explanation:

point P1 (5,35) in the form (x1,y1)

point P2(-6,-31) in the form (x2,y2)

slope = m

m = (y2-y1) / (x2-x1)

m = (-31-35) / (-6-5)

m = -66 / -11

they made it easy for you , huh

m = 6

use point / slope fomula, y-y1 = m(x-x1) and plug in one point, either would work, since i've already labeled it with point P1, let's use that point

y-35 = 6(x-5)

y-35 = 6x-30

y = 6x - 30 + 35

y = 6x + 5

Maya, this really is a very common question on here, I really am curious about what's tricky in the problem for you and many many others. please let me know in comments section, thanks MMM

Janelle can walk 3 3/4 miles in 1 1/2 hours. at this rate how many miles can janelle walk in 4 hours

liberstina [14]

Set up a ratio 3 3/4 = 15/4 and 1 1/2 = 3/2 so
((15/4miles) / (3/2hours)) = xmiles/4hours solve for x
so x = 4hours*((15/4miles)/(3/2hours)) = x miles
the hours cancel and you are left with x miles = 10miles
