Answer:

4x^2 + 7y^3 + 6xy

Step-by-step explanation:

2x^2+2y^3-6xy + 2x^2+5y^3+12xy

2x^2 + 2x^2 = 4x^2

2y^3 + 5y^3 = 7y^3

-6xy + 12xy = 6xy

Expression for perimeter of triangle = 5x+8

Step-by-step explanation:

Given that:

Length of bottom of triangle = b = x

Length of other side = a = 3x + 5

Length of last side = c = x + 3

Perimeter of triangle = a + b + c

Perimeter = (3x+5)+x+(x+3)

Perimeter = 3x+5+x+x+3

Perimeter = 5x + 8

Hence,

Expression for perimeter of triangle = 5x+8

A, B, and C

Step-by-step explanation:

The true statements are B, C and E.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given is a graph of the amount of water in a bathtub with respect to time.

A) This statement means that the slope of the line at 10 : 01 pm is smaller than that of at 10 : 14 pm.

The line is steeper at 10:01 pm than that at 10:14 pm. That is the tangent of the angle making with the x axis at 10:01 pm is higher than that at 10:14 pm.

So the tub is filling at a faster rate at 10:01 pm than at 10:14 pm.

B) At 10:06 pm, the amount of water is constant at 30 gallons. So this statement is correct.

C) The maximum amount of water in the tub was about 35 gallons is a correct statement since after that the tub was draining.

D) The amount of water in the tub stayed the same from 10:16 pm to 10:20 pm is not correct, since the water was draining during the time and thus, water was decreasing.

E) It took 4 minutes for the tub to drain. It is correct since the draining starts at 10:16 pm and ends at 10:20 pm.

Hence the correct statements are B, C and E.

Answer:

11371.4

Step-by-step explanation:

delta math

The length of n is 11373.1 inches

For given example,

As we know for ΔNOP,

[tex]\frac{n}{sinN}=\frac{0}{sinO}=\frac{p}{sinP}[/tex]

We know that the sum of all angle of triangle is 180°

For ΔNOP,

⇒ ∠N +∠O + P = 180°

⇒ 16° + ∠O + 163° = 180°

⇒ ∠O = 180 - 179

⇒ ∠O = 1°

The length of n is,

[tex]\frac{n}{sinN}=\frac{0}{sin1}\\\\n(sin1)=0(sin16)\\\\0.01745(n)=720(0.27564)\\\\n=\frac{198.4608}{0.01745}\\\\n=11373.112\\\\n\approx 11373.1~in.[/tex]

Therefore, the length of n is 11373. 3 inches

Answer:

(f + g)(3) = 9

Step-by-step explanation:

Given:

f(x) = x² + 1

g(x) = x - 4

Required:

(f + g)(3)

SOLUTION:

✔️Find f(3) by substituting x = 3 into f(x) = x² + 1:

f(3) = (3)² + 1 = 9 + 1

f(3) = 10

✔️Find g(3) by substituting x = 3 into g(x) = x - 4:

g(3) = 3 - 4

g(3) = -1

✔️Find (f + g)(3):

(f + g)(3) = f(3) + g(3)

= 10 + (-1)

= 10 - 1

(f + g)(3) = 9

first choice: y≥1/3 x+3 and 3x-y>2

Step-by-step explanation:

The system of linear inequalities is: [tex]y \ge \frac{1}{3}x + 3[/tex] and [tex]3x -y > 2[/tex]

The equation of the orange line is calculated using:

[tex]y = \frac{y_2 - y_1}{x_2-x_1} \times (x -x_1) + y_1[/tex]

This gives

[tex]y = \frac{3- 4}{0-3} \times (x -3) + 4[/tex]

[tex]y = \frac{- 1}{-3} \times (x -3) + 4[/tex]

[tex]y = \frac{1}{3} \times (x -3) + 4[/tex]

Open the bracket

[tex]y = \frac{1}{3}x -1 + 4[/tex]

[tex]y = \frac{1}{3}x + 3[/tex]

The inequality has a thick line, and the upper region is shaded.

So, the inequality is:

[tex]y \ge \frac{1}{3}x + 3[/tex]

The equation of the gray line is calculated using:

[tex]y = \frac{y_2 - y_1}{x_2-x_1} \times (x -x_1) + y_1[/tex]

This gives

[tex]y = \frac{4- 1}{2-1} \times (x -1) + 1[/tex]

[tex]y = \frac{3}{1} \times (x -1) + 1[/tex]

[tex]y = 3 \times (x -1) + 1[/tex]

Open the bracket

[tex]y = 3x -3 + 1[/tex]

[tex]y = 3x -2[/tex]

The inequality has a dotted line, and the right region is shaded.

So, the inequality is:

[tex]y < 3x -2[/tex]

Rewrite as:

[tex]3x -2 > y[/tex]

So, we have:

[tex]3x -y > 2[/tex]

Hence, the system of linear inequalities is:

[tex]y \ge \frac{1}{3}x + 3[/tex] and [tex]3x -y > 2[/tex]

Step-by-step explanation:

We have y = 9x - 70 and y = 2x - 32.

=> 9x - 70 = 2x - 32

=> 7x = 38

=> x = 38/7 which is around 5.43.

Answer:

Equations are :--- y = 9x – 70 and y = 2x – 32

Substituting the value of y, we get

[tex]9x - 70 = 2x - 32 \\ 7x = 38 \\ x = \frac{38}{7} \\ \boxed{x = 5.43} \\ y = 9x - 70 \\ y = 9( \frac{38}{7} ) - 70 \\ \boxed{ y = - 21.14}[/tex]

Step-by-step explanation:

(1, -2) ; Slope (m) = 4

Equation of the line : y - y₁ = m(x - x₁)

y - [-2] = 4(x - 1)

y + 2 = 4x - 4

     y = 4x - 4 - 2

     y = 4x - 6
