Answer:

x = -15 or 15

Step-by-step explanation:

We can simplify |x| - 3 = 15 to |x| = 15 because we can add 3 on both sides due to -3 being outside of the absolute value bars. Next, we can say that x is either 15 or -15 because of the absolute value (|15| is equal to 15 and |-15| is also equal to 15).

X = -15 or 15
The absolute value of either of those is 15 subtract 3 and it = 12

*EASY* WILL MARK BRAINEST! Find the slope of the line in the image below!
Gala2k [10]

Answer:

5/4

Step-by-step explanation:

We have two points so we can use the formula for slope

(-3,-2) (1,3)

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

   = (3--2)/(1--3)

    = (3+2)/(1+3)

    =5/4

The slope is 5/4

What is the difference between the volume of a cone and the volume of the cylinder
amm1812

The volume of a cone is always 3 times smaller than that of its corresponding cylinder (that is, a cylinder with the same height and base radius).

As in:

Volume of a cylinder= πr²h

and Volume of a cone=⅓πr²h

But just in case you were referring to an actual difference, then that would be ⅔πr²h, since 1—⅓ = ⅔.

Write an equation for the line in slope intercept form to parallel to -x + 3y =-2 that contains the point (12,7)
kvasek [131]

The parallel lines have the same slope.

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have

-x+3y=-2\qquad|\text{add x to both sides}\\\\3y=x-2\qquad|\text{divide both sides by 3}\\\\y=\dfrac{1}{3}x-\dfrac{2}{3}\to m=\dfrac{1}{3}

Therefore searched line equation is:

y=\dfrac{1}{3}x+b

The line passes through point (12, 7). Put the coordinates of the point into the equation of the line:

7=\dfrac{1}{3}(12)+b\\\\7=4+b\qquad|\text{subtract 4 from both sides}\\\\3=b\to b=3

Answer: y=\dfrac{1}{3}x+3

Find the area of the region under the graph of f on [a, b].<br> f(x) = x2 − 8x + 17; [−1, 2]
Harman [31]

Answer:

The area is 42 area units.

Step-by-step explanation:

The area of a function f(x) on an interval [a,b] is given by:

A = \int\limits^a_b {f(x)} \, dx

Applying to this question:

A = \int\limits^-1_2 {x^2 - 8x + 17} \, dx

Then

F(x) = \frac{x^{3}}{3} - 4x^{2} + 17x

A = F(2) - F(-1)

F(2) = frac{2^{3}}{3} - 4*2^{2} + 17*2 = \frac{8}{3} + 18 = \frac{8 + 3*18}{3} = \frac{62}[3}

F(-1) = frac{(-1)^{3}}{3} - 4*(-1)^{2} + 17*(-1) = -\frac{1}{3} - 21 = \frac{-1 - 21*3}{3} = -\frac{64}[3}

A = F(2) - F(-1) = \frac{62}[3} - (-\frac{64}[3}) = \frac{62+64}{3} = 42

The area is 42 area units.

Anyone know how to do these and explain so I can do the rest lol.
klasskru [66]

Answer:

Option B. m⁷/n²  is the correct answer.

Step-by-step explanation:

Identity,

xᵃ * xᵇ = xᵃ⁺ᵇ  

xᵃ/xᵇ = xᵃ⁻ᵇ

x⁻ᵃ = 1/xᵃ

It is given that,

m⁻⁶ n⁻³/m⁻¹³ n⁻¹

Using  these three identities we can write,

m⁻⁶ n⁻³/m⁻¹³ n⁻¹ = m⁻⁶ m¹³/n⁻¹n³   (since x⁻ᵃ = 1/xᵃ)

m⁻⁶ m¹³/n⁻¹n³ =m⁽⁻⁶⁺¹³⁾/n⁽⁻¹⁺³⁾ = m⁷/n²  (since xᵃ * xᵇ = xᵃ⁺ᵇ   and xᵃ/xᵇ = xᵃ⁻ᵇ)

Therefore Option B. m⁷/n² is the correct answer
