Answer:
x = 3 and x = -12
Step-by-step explanation:
To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:
| 2x + 9 | = 15 becomes:
2x + 9 = 15 and 2x + 9 = -15
2x = 6 and 2x = -24
x = 3 and x = -12
Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.

Write an equation in the form y=Mx+b to model the given representation
Answer:
y= 20x +30
Step-by-step explanation:
y - intercept of the graph is 30
Slope of the graph is [tex]\frac{20}{1}[/tex]
Answer:
y = 20x + 30
Step-by-step explanation:
y=mx+b
b value = y-intercept, so you find where the line crosses the y-axis.
Find point at (0,30); b = 30
m value = rise/run (rise over run) (y/x)
find the next point that the graph intersects at and count add to it to find 30.
the closest point is at (-1,10)
go back to rise/run
30-10 = 20
0-(-1) = 1
20/1 =20 is your m value
plug m value and b value into equation to form your line.
y=20x+30

What is the value of n in the equation (4^3)^6 = 4^n
pls help
Answer:
Step-by-step explanation:
You can solve this by applying the fact that when an exponent is applied on top of a base raised to another exponent, those exponents can be multiplied:
Let's solve it:
[tex](4^3)^6 = 4^n\\4^{18} = 4^n\\n = 18[/tex]

A bridge is 10 m above a railroad track and at right angles to it. A train is running at the rate of 20 m/s passes under the center of the bridge at the same instant that a car running 15 m/s reaches that point. How rapidly are they separating 3 seconds later?
The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.
Calculation of the time taken:Here the point should be considered directly under the center of the bridge as the origin
Here
x = 20t, y = 15t, z = 10
let us assume s be the distance between them at time t,
So it be like
[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]
2s ds/dt = 1250t
ds/dt = 625t/s
Now at the time when
t = 3,
[tex]s = \sqrt (625*9+100)[/tex] = 75.6637
So,
ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

How can knowing the slope and y-intercept help you graph an equation?
Answer:
To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.help i suck at math lolll

3/8x−1/3x+6=x find x
Step-by-step explanation:
3/8x-1/3x+6=x
(3(3x)-1(8x))/24=x-6
(9x-8x)=24(x-6)
x=24x-24×6
x=24x-144
144=24x-x
23x=144
x=144/23
A line segment has endpoints at (1, 3) and (3,1). If the line segment is translated 2 units up and 2 units to the right, what are the new coordinates of the second point? a.(1, 3) b. (5, 3) c. (3, 3) d.(5, 1 )
Answer:
B: (5,3)
Step-by-step explanation:
The second point is (3,1)
2 units up is +2
2 units right is also + 2
So the new coordinates will be;
(3 + 2, 1 + 2) •= (5,3)
