Answer:
The graph of g is 3 units above the graph of f.
Step-by-step explanation:
Adding 3 to each y-value shifts the graph up 3 units.
__
In the case of the straight line given here, it also has the appearance of shifting the graph left. The left-shift, however, is not 3 units. The amount of apparent horizontal shift will depend on the slope of the original line.

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.
⚽ 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.Solve.
y= 2x - 6
4x – 2y = 14
Use the substitution method.
Answers
Answer:
y=2x-6. ---------(1)
4x-2y=14. --------(2)
substituting equation 2 in 1
4x-2(2x-6)=14
4x-4x+12=14

A classroom is 11 m long, 8 m wide and 5.5 m high Find the sum of the areas of the four walls.
( please show the working out pleaseee)
Answers
Answer:
209 m²
Step-by-step explanation:
The class room has a measurement of 11 m long, 8 m wide and 5.5 m high. Hence the walls of the classroom would be 4, with the following measurements.
Wall 1: 11 m by 5.5 m, Wall 2: 8 m by 5.5 m, Wall 3: 11 m by 5.5 m and Wall 4: 8 m by 5.5 m
The area of wall 1 = 11 m * 5.5 m = 60.5 m²
The area of wall 2 = 8 m * 5.5 m = 44 m²
The area of wall 3 = 11 m * 5.5 m = 60.5 m²
The area of wall 4 = 11 m * 5.5 m = 44 m²
The sum of areas of the fall wall = area of wall 1 + area of wall 2 + area of wall 3 + area of wall 4
The sum of areas of the fall wall = 60.5 + 44 + 60.5 + 44 = 209 m²
A line is perpendicular to y = 3x - 8
and intersects the point (2,2).
What is the equation of this
perpendicular line?
Answers
Since the line is perpendicular, we know that the slope is reciprocal and negative to the other one.
So,
y = -4x + b
We want to find the y-intersect (b) so substitute the intersected points and solve for it.
2 = -4(2) + b
2 = -8 + b
2 + 8 = b
10 = b
So the complete equation would be:
y = -4x + 10

Answer:
A: 2/9
Step-by-step explanation:
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

Hope this helped have an amazing day!
The two rectangles are similar and the scale factor is 3/2.
Given data:
The first rectangle is represented as ABCD
The second rectangle is represented as PQRS
Now, the dimensions of ABCD is 8 cm x 6 cm
The dimensions of PQRS is 12 cm x 9 cm
So, the scale factor is represented as k and the value of k is :
k = length of PQRS / length of ABCD
So, k = 12 / 8
k = 3/2

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,

Therefore, according to the definition of similarity,
We have,
CD / CB = BD / BA = 16/17.89
