Answer:

y = -3

Step-by-step explanation:

-3(y-5) = 24

Divide each side by -3

-3(y-5)/-3 = 24/-3

y - 5 = -8

Add 5 to each side

y-5+5 = -8+5

y = -3

Answer:

y= -3

Step-by-step explanation:

-3(y-5)= 24

Do distributive property so, -3y + 15= 24

Subtract 15 from both sides so, -3y + 15 - 15= 24 - 15

Divide -3 from both sides to leave y on one side so, -3/-3y= 9/-3

The answer would be y= -3.

Answer:

(W2-1)xW

Step-by-step explanation:

The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!

Based on the problem statement, we have a word problem before us, that is solving for the area of a rectangle with given sides.

Area =  2y^2-y

Given data

Let the Length of the rectangle be x

and let the width be y

From the statement "The length of a rectangle is 1 less than twice the width"

the length can we re-written as

x = 2y-1

We know that the area of a rectangle is

Area = Length*Width

Area = (2y-1 )* y

Area = 2y^2-y

hence the expression for the area is given as 2y^2-y

Answer:

h(t) = 36sin(1440x)+ 40

Step-by-step explanation:

Given the information:

y = a sin (bx+c) + k for different values of a, b, and c

=> Amplitude (a) = (highest point - lowest point) / 2 = 36

=> asymptom (k) =  (highest point - lowest point) / 2 = 40

=> model for the height of the rope in inches as a function of time in seconds given that the rope starts at its lowest point is:

h(t) = 36sin(1440x)+ 40

**corrected mistake**

hello,

here is your answer:

**********

volume of cylinder = [tex]\pi[/tex]r²h

radius = 12 units

height = 15 units

volume = r² × h × [tex]\pi[/tex]

= 12² × 15 × [tex]\pi[/tex]

= 144 × 15 × [tex]\pi[/tex]

= 2160 × [tex]\pi[/tex]

ans = A. 2160[tex]\pi[/tex] units³

**********

hope this helped,

:)

The volume of cylinder is 2160 [tex]units^{3}[/tex].

Volume is the measure of the capacity that an object holds.

The formula for the volume of cylinder is

[tex]v = \pi r^{2}h[/tex]

Where,

V is the volume of cylinder.

r is the radius of cylinder.

h is the height of cylinder.

π = 3.14

According to the given question

Height of the cylinder, h = 15 units

Radius of the cylinder, r = 12 units

Therefore, the volume of the cylinder is given by

[tex]v = \pi (12)^{2}(15)[/tex]

v = π × 144 × 15

V = 2160π [tex]units^{3}[/tex]

Hence, the volume of cylinder is 2160 [tex]units^{3}[/tex].

D. 75

Step-by-step explanation:

A triangle’s angles equal 180 degrees according to the Triangle Sum Theroem. So, 180-70-35=75.

PLZ MARK BRAINLIEST!!!

Answer:

D. 75 degrees

Step-by-step explanation:

The three angles of a triangle have to add up to be 180 degrees. 70+35= 105, and 180-105= 75. Therefore, the third angle must be 75 degrees in order for it to be a proper triangle.

Answer:

f(-2) = 1.

Step-by-step explanation:

If we are solving for f(-2), we will simply need to substitute in '-2' for 'x'. This gives us:

f(-2) = -2 + 3

f(-2) = 1.

Evaluate f(x) = x + 3 for f(-2)

Given: x = -2

Plug in -2 for x in the equation:

f(x) = x + 3

f(-2) = (-2) + 3

f(-2) = 3 - 2

f(-2) = 1

f(-2) = 1

1 is your answer.

Step-by-step explanation:

Answer:

y = e^x - 4

Step-by-step explanation:

The missing options are

y = ln x - 3

y = ln x - 4

y = e^x - 3

y = e^x - 4

The function is defined in quadrant 3 and increases exponentially, then it is not a logarithm.

f(x) crosses the y-axis at (0, -3). Replacing x = 0 the last option, we get:

y = e^0 - 4 = 1 - 4 = -3

y = e^x - 4

Answer: 8

Step-by-step explanation:

Distance formula: square root x2-x1 squared + y2-y1 squared.

15-15=0

0 squared=0

-19- -11= -8

-8 squared=64

Square root 64= 8

Answer:

8 units

Step-by-step explanation:

the easiest way to work out the distance for these two points is to plot them on a linear graph. as they are in line (because they're both inline with 15 on the x-axis), you just have to count the numbers between -11 and -19. in this case there are 8 units between the two points.
