Answer:

9x² + 16y² - 24xy

Step-by-step explanation:

(3x - 4y)²

⇒ (3x)² + (4y)² - 2 (3x) (4y)                                            {(a - b)² = a² + b² - 2ab}

⇒ 3²x² + 4²y² - 2 (12xy)

⇒ 9x² + 16y² - 24xy

Step-by-step explanation:

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Up

Vertex: (0,−2)

Focus:

Answer:

8 ft

Step-by-step explanation:

the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.

Solve for the base of the right angle triangle using pythagorean's theorem:

c=20, a=18, b=?

[tex]b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}[/tex]

[tex]b=\sqrt{72}[/tex]

[tex]b= 8.49 ft[/tex]

round to the nearest foot,

b = 8 ft

Given :

A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft.

To Find :

The height corresponding to the 8 ft base.

Solution :

Since, both parallelogram are similar. So, ratio of the sides of parallelogram is similar in both the cases.

[tex]\dfrac{h_1}{h_2}=\dfrac{b_1}{b_2}\\\\\dfrac{8}{14}=\dfrac{h_1}{4}\\\\h_1 = \dfrac{8\times 4}{14}\\\\h_1 = 2.285 \ ft[/tex]

Therefore, the height corresponding to the 8 ft base parallelogram is 2.285 ft.

Yes, The number 379,098 is divisible by 9

As, the divisibility rule of 9 is sum of all digits is divisible by 9.

Here, 3+7+9+0+9+8

Answer:

Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.

Step-by-step explanation:

The general equation of a straight line is

y = mx + b

for y = 150x

We have the slope as 150

This is 150 miles/hour

This relates to Jesse’s train speed

for Khalid, we have his own speed obtainable from the graph

The speed is simply the slope of the graph

We proceed to select two points from the graph and find the slope

The points are; ((1,140) and (4,560)

Mathematically, the slope will be;

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

m = (560-140)/(4-1) = 420/3 = 140 miles per hour

Answer:

A=2.5

B=2

Step-by-step explanation:

A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.

We can compare the two sides using algebra.

4b+7=8b-1

Using simple methods, we can isolate b on a single side.

1+7=8b-4b

8=4b

b=2

From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.

2a = 2b+1

2a = 2(2)+1

2a=4+1

2a=5

a=2.5

Responder:

Los valores de y son 3/5 y -1

Los valores de x son = -12/5 y -4

Explicación paso a paso:

Dadas las eqautions;

x + 3 = y ...... 1

x ^ 2- 16y ^ 2 = 0 ..... 2

Sustituya la ecuación 1 en 2 que tendremos;

x ^ 2- 16y ^ 2 = 0

x² - 16 (x + 3) ² = 0

x²-16 (x² + 6x + 9) = 0

x²-16x²-96x-144 = 0

-15x²-96x-144 = 0

15x² + 96x + 144 = 0

5x² + 32x + 48 = 0

Al factorizar tendremos;

5x + 12 = 0 yx + 4 = 0

x = -12/5 y -4

Obtenga los valores de y;

recuerda que y = x + 3

Si x = -12/5

y = -12/5 + 3

y = 3/5

Si x = -4

y = -4 + 3

y = -1

Por tanto, los valores de y son 3/5 y -1

Answer:

48 ounces

Step-by-step explanation:

Let the amount in small container be x and that of largest be y

If a small container of detergent holds 75% as much as the large container of detergent, this can be represented as;

x = 75% of y

Given x = 36

36 = 75% of y

36 = 0.75y

y = 36/0.75

y = 48 ounces

Hence the large container will hold 48 ounces
