What is the solution to the following system of equations?

x − 3y = 6
2x + 2y = 4

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

Answers

Answer:

The solution to the system of equations be:

[tex]x=3,\:y=-1[/tex]

Hece, option B is correct.

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}x-3y=6\\ 2x+2y=4\end{bmatrix}[/tex]

Multiply x − 3y = 6 by 2:      2x-6y=12

[tex]\begin{bmatrix}2x-6y=12\\ 2x+2y=4\end{bmatrix}[/tex]

so

[tex]2x+2y=4[/tex]

[tex]-[/tex]

[tex]\underline{2x-6y=12}[/tex]

[tex]8y=-8[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}2x-6y=12\\ 8y=-8\end{bmatrix}[/tex]

Solve 8y = -8 for y

[tex]8y=-8[/tex]

Divide both sides by 8

[tex]\frac{8y}{8}=\frac{-8}{8}[/tex]

[tex]y=-1[/tex]

[tex]\mathrm{For\:}2x-6y=12\mathrm{\:plug\:in\:}y=-1[/tex]

[tex]2x-6\left(-1\right)=12[/tex]

[tex]2x+6=12[/tex]

subtract 6 from both sides

[tex]2x+6-6=12-6[/tex]

[tex]2x=6[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{6}{2}[/tex]

[tex]x=3[/tex]

Therefore, the solution to the system of equations be:

[tex]x=3,\:y=-1[/tex]

Hence, option B is correct.

A N S W E R :

x - 3y = 6 ......[Equation (i) ]2x + 2y = 4 ......[Equation (ii)]

⚽ From Equation (i) we get :

x = 6 + 3y......[Equation (iii)]

⚽ Now, Substitute the equation (iii) in equation (ii) we get :

→ 2(6 + 3y) + 2y = 4

→ 12 + 6y + 2y = 4

→ 8y = 4 - 12

→ 8y = -8

→ y = -8 ÷ 8

y = -1

⚽ Now Substituting value of y = -1 in equation (iii) we get :

→ x = 6 + 3y

→ x = 6 + 3(-1)

→ x = 6 + (-3)

→ x = 6 - 3

x = 3

Hence,the value of x = 3 and value of y = -1.

Suppose you know that the volume of the following prism is represent by V(x) = -2x^3 + 14x^2 + 120x.

Answers

Step-by-step explanation:

-2x³ + 14x² + 120x

= -2x(x² - 7x - 60)

= -2x(x - 12)(x + 5).

The other 2 dimensions are -2x and (x + 5).

When using a graphing calculator to maximise the volume of the prism, we get x = 7.378. However this value is not reasonable as it makes -2x and (x - 12) negative, which are the sides of the prism.

What is an equation of the line that passes through the points (1, 2) and (2, -1)?
Put your answer in fully reduced form.

Answers

Answer:

y = -x + 3

Step-by-step explanation:

The equation of a straight line is generally written as;

y = mx + b

where m is the slope and b is the intercept

To get the slope we use the slope formula

Mathematically, that is;

m = (y2-y1)/(x2-x1) = (-1-2)/2-1 = -3/1 = -1

To get the intercept we equate any of the points to the partial equation that we have;

From;

y = -x + b

2 = -1 + b

b = 1 + 2 = 3

So the equation is;

y = -x + 3

Answer:

Step-by-step explanation:

The value of sin x in the given right triangle is 0.894.

What sine of an angle?

The sine of an angle is a trigonometric function that is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle.

Given is right triangle ABC, we need to find the value of sin x,

So, we see that the figure is divided into three similar triangles,

Namely,

Δ CDB ~ Δ BDA ~ Δ CBA,

Therefore, according to the definition of similarity,

We have,

CD / CB = BD / BA = 16/17.89

Therefore, BD / BA = 0.894

Also,

sin x = BD / BA

Therefore,

sin x = 0.894

Hence the value of sin x in the given right triangle is 0.894.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 450 nails. The contractor bought twice as many large boxes as small boxes, which altogether had 4200 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.

Answers

Step-by-step explanation:

Let s represent the number of small boxes and l represent the number of large boxes.

We have 2s = l and 150s + 450l = 4200.

Therefore 150s + 450(2s) = 4200,

150s + 900s = 4200, 1050s = 4200, s = 4.

l = 2s = 2(4) = 8.

Hence there are 4 small boxes and 8 large boxes.

A ball is thrown upward at an angle of 30° to the horizontal and lands on the top edge of a building that is 20 m away. The top edge is 5.0 m above the throwing point. How fast was the ball thrown? Use: sin30°=0.5 and cos30°=0.9
a. 20 m/s
b. 11 m/s
c. 52.3 m/s
d. 16 m/s​

Answers

Answer:

The correct option is;

a. 20 m/s

Step-by-step explanation:

The given parameters are;

The angle at which the ball is thrown, θ = 30° to the horizontal

The horizontal distance of the top edge of the building where the ball lands from where the ball is thrown, x = 20 m

The height of the top edge of the building above the throwing point = 5 meters

Let "v" represent the speed with which the ball is thrown

We have;

The vertical component of the speed with which the ball is thrown, [tex]v_y[/tex] = v × sin(θ) = v × sin(30°) = v × 0.5 = 0.5·v

[tex]v_y[/tex] = 0.5·v

The horizontal component of the speed with which the ball is thrown, vₓ = v × cos(θ) = v × cos(30°) = v × 0.9 = 0.9·v

vₓ = 0.9·v

The kinematic equation of the motion is y = [tex]v_y[/tex]·t - (1/2)·g·t², where;

y = The vertical height reached = 5 metes

t = The time taken to reach the specified 5 m, height

g = The acceleration due to gravity = 9.8 m/s², we have;

Therefore, we have;

5 = 0.5·v·t - (1/2)·9.8·t²...(1)

Also, from the horizontal motion of the ball, we have the following kinematic equation of motion;

x = vₓ × t

Therefore, by substituting the known values, we have;

20 = 0.9·v × t

∴ v = 20/(0.9·t) = 200/(9·t)...(2)

Substituting the value of t in equation (1) gives;

5 = 0.5·v·t - (1/2)·9.8·t² = 0.5·(200/(9·t))·t - (1/2)·9.8·t²

∴ 5 = 0.5·(200/(9·t))·t - (1/2)·9.8·t² = 100/9 - 4.9·t²

4.9·t² = 100/9 - 5 = 55/9

t = √(55/(9 × 4.9)) ≈ 1.116766

The time taken to reach the specified 5 m height = t ≈ 1.116766 seconds

From equation (2), we have, v = 200/(9·t) = 200/(9 × 1.116766) ≈ 19.8987 m/s

The speed with which the ball is thrown = v ≈ 19.8987 m/s ≈ 20 m/s. to the nearest whole number.

The speed with which the ball is thrown is approximately 20 m/s

Answer:

The answer is:

a) 20 m/s
