The sum of two numbers a and b is equal to c. The number line below shows the values of a and c. What is the value of b?​

Answer:

1) 13 inches

2) 2z=x

3) 48 inches

Step-by-step explanation:

it snows 4/2 = 2 inches perhour

1. 2x 6.5 = 13 inches

2. y = 2z

3. 2x 24 = 48 inches

Answer:

The equation is: y y = 5/4 * x - 13

Step-by-step explanation:

The slope-intercept y = mx + c form of a straight line is In this case we have a point, (x, y) and the slope, m so all we need is a value for c. Substitute into y = mx + c - 3 = 5/4 * (8) + c - 3 = 10 + c c = - 13 y = 5/4 * x - 13 The equation is: y Or you can use the formula for the situation where you have a point, (x 1 ,y 1 ) and the slope, (m) y-y 1 =m(x-x 1 ) y - (- 3) = 5/4 * (x - 8) y + 3 = 5/4 * x - 10 y = 5/4 * x - 13

Answer: 5400 cm^2

Step-by-step explanation:

15 x 20 x 9 x 2 = 5400

Answer:

5400

Step-by-step explanation:

to get volume you multiply length by width by height. so 15 x 20 x 9 which equals 2700. but there are 2 prisms, so you multiply by 2 which equates to 540

Answer: y= k/m - x

Step-by-step explanation:

First you need to divide both sides by( M

(m(x+y)) / m = k/m

x + y - x = k/m - x

y = k/m - x

Answer:

The top box:  3

The middle box:  2

The bottom box:  1

Step-by-step explanation:

In order to fill out the yellow boxes we have to use the equation above the table, and plug in the x values, and so we get...

If x = 2, then

y = x + 1

y = 2 + 1

y = 3

If x = 1, then

y = x + 1

y = 1 + 1

y = 2

If x = 0, then

y = x + 1

y = 0 + 1

y = 1

Answer:

(-2, -4)

Step-by-step explanation:

When a point is rotated 180 degrees around the origin, the values turn into their opposites.

(2, 4) ⇒ (-2, -4)

Answer:

(-2,-4)

Step-by-step explanation:

You have it correct.  It would move from quadrant I to quadrant III and both values become negative.

(-2,-4)

Answer:

114 cm^2

Step-by-step explanation:

area of a triangle= base x height divided by 2

Answer:

Triangle = 114 ft²

Rectangle = 374 ft²

Total figure = 488 ft²

Step-by-step explanation:

Triangle = 1/2 b*h

Triangle = 1/2(12x19)

Triangle = 1/2(228)

Triangle = 114 ft²

Rectangle = 22 x 17

Rectangle = 374 ft²

Total area = 114 ft² + 374 ft²

Total area = 488 ft²

Answer:

864 squared

Step-by-step explanation:

Answer:

This is a right angle triangle so

[tex] {hyp}^{2} = {opp}^{2} + {adj}^{2} [/tex]

[tex] {42}^{2} = a {}^{2} + 30 {}^{2} \\ 1764 = a {}^{2} + 900 \\ {a }^{2} = 1764 - 900 \\ a { }^{2} = 864 \\ a = \sqrt{864 } \\ a = 29.39[/tex]

Answer:

y = -4x + 3

Step-by-step explanation:

(0, 3) and (2, -5)

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

m= (-5-3)/(2-0)

m= (-8)/2

m = -4

y - y1 = m(x - x1)

y - 3 = -4(x - 0)

y - 3 = -4x + 0

y = -4x + 3

Answer:

Step-by-step explanation:

The graph of g(x) = f(x) - 4 is the same as that of f(x), EXCEPT that it has been translated down by 4 units.  

The graphs of  f(x)=12x2 + 1   and  g(x)=f(x)−4 are both parabolas that open up and have their vertices on the same vertical line (the y-axis).

Answer:

[tex]\displaystyle \lim_{x \to \infty} \frac{x^2}{1 + 3x + 5x^2} = \frac{1}{5}[/tex]

General Formulas and Concepts:

Calculus

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \lim_{x \to \infty} \frac{x^2}{1 + 3x + 5x^2}[/tex]

Step 2: Determine Rule

If the highest power of x in a rational expression is the same both numerator and denominator, then the limit as x approached ∞ would be the highest term coefficient in the numerator divided by the highest term coefficient in the denominator.

Step 3: Identify

Numerator highest power: x²

Denominator highest power: 5x²

Step 4: Evaluate

Apply rule.

[tex]\displaystyle \lim_{x \to \infty} \frac{x^2}{1 + 3x + 5x^2} = \frac{1}{5}[/tex]

Answer:

D) The third side could be 4 meters long.

Step-by-step explanation:

The third side of a triangle must be greater than the difference and less than the sum of the other two sides.

5-4=1

5+4=9

So the third side must be GREATER THAN 1 and LESS THAN 9.  (1<x<9)

Therefore, the answer can't be A or C.  The second one could be correct, depending on how much less than 4 it is.  But the last one is definitely correct.

Answer:

x = 7.423891441

Step-by-step explanation:

Hey There!

So they want you to solve for x using law of sines

Law of sines states that sin ( an angle) divided by it's opposite side equals sin( a different angle) divided by its opposite side

so basically

[tex]\frac{sin23}{x} =\frac{sin90}{19}[/tex]

now we can solve for x

step 1 multiply each side by sin 23

the fraction would split and it would be

[tex]x=\frac{19sin23}{sin90}\\x = 7.423891441[/tex]

So we can conclude that x = 7.423891441

Complete Question:

The perimeter of triangle DEF is 3x + 3y. Find the measure of the missing side. (One side is x-y, the other is x+y)

Answer:

[tex]Side\ 3 = 2x+ 3y[/tex]

Step-by-step explanation:

Given

[tex]P = 4x + 3y[/tex] --- Perimeter

[tex]Side\ 1 = x - y[/tex]

[tex]Side\ 2 = x + y[/tex]

Required

Determine Side 3

The perimeter of a triangle is calculated as:

[tex]Permeter = Side\ 1 + Side\ 2 + Side\ 3[/tex]

[tex]4x + 3y = x - y + x + y + Side\ 3[/tex]

Collect Like Terms

[tex]4x - x - x+ 3y-y + y = Side\ 3[/tex]

[tex]2x+ 3y = Side\ 3[/tex]
