Answer 1

Answer:

A & B

Step-by-step explanation:

See attachment for complete question

Given

[tex]y = \frac{1}{2}x[/tex]

Analyzing the given options

Option A:

[tex]6y = 3x[/tex]

Divide both sides by 6

[tex]\frac{6y}{6} = \frac{3x}{6}[/tex]

[tex]y = \frac{3x}{6}[/tex]

[tex]y = \frac{1}{2}x[/tex]

This is true for the given expression:

Option B:

From the graph:

x = 2, when y = 1

x = 4, when y = 2

Solving for the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2 -1}{4 - 2}[/tex]

[tex]m = \frac{1}{2}[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

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

[tex]y - 1 = \frac{1}{2}x - 1[/tex]

Add 1 to both sides

[tex]y - 1 +1 = \frac{1}{2}x - 1 + 1[/tex]

[tex]y = \frac{1}{2}x[/tex]

This is also true for the given expression.

Option C:

From the graph:

x = 2, when y = 4

x = 4, when y = 8

Solving for the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{8 - 4}{4 - 2}[/tex]

[tex]m = \frac{4}{2}[/tex]

[tex]m =2[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 4 = 2(x - 2)[/tex]

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

Add 4 to both sides

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

[tex]y = 2x[/tex]

This isn't true for the given expression.

Option (D):

From the table:

x = 2, when y = 1

x = 4 when y = 3

Solving for the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{3 - 1}{4 - 2}[/tex]

[tex]m = \frac{2}{2}[/tex]

[tex]m = 1[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 1 = 1 * (x - 2)[/tex]

[tex]y - 1 = x - 2[/tex]

[tex]y = x - 2 +1[/tex]

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

This isn't true for the given expression.

If p varies directly as
the cube of q, and p =
26 when q = 2, find p
when q = 5

Answers

Answer:

The value of p at q = 5 is 406.25

Step-by-step explanation:

p varies directly as the cube of q

→ That means p ∝ q³

The equation of variation is p = kq³, where k is the constant of variation

∵ p = 26 when q = 2

→ Use them to find the value of k

∵ 26 = k(2)³

∴ 26 = k(8)

∴ 26 = 8k

→ Divide both sides by 8

∴ [tex]\frac{26}{8}=\frac{k}{8}[/tex]

3.25 = k

→ Substitute it in the equation of variation

p = 3.25 q³ ⇒ equation of variation

q = 5

→ Substitute it in the equation of variation to find p

∴ p = 3.25 (5)³

p = 406.25

The value of p at q = 5 is 406.25

Solve the following system of equations. y + 5x = 30 2y = 5x + 15

Answers

Answer: Solve   2y-5x-30  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2y-5x-30  = 0 and calculate its properties

Step-by-step explanation:

Answer:

x = 3, y = 15

Step-by-step explanation:

Given the 2 equations

y + 5x = 30 → (1)

2y = 5x + 15 → (2)

Subtract 5x from both sides in (1)

y = 30 - 5x → (3)

Substitute y = 30 - 5x into (2)

2(30 - 5x) = 5x + 15 ← distribute left side

60 - 10x = 5x + 15 ( subtract 5x from both sides )

60 - 15x = 15 ( subtract 60 from both sides )

- 15x = - 45 ( divide both sides by - 15 )

x = 3

Substitute x = 3 into (3) for corresponding value of y

y = 30 - 5(3) = 30 - 15 = 15

Thus solution is x = 3, y = 15

Elsa is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 43 feet and its width is 36 feet. Suppose each can of wood stain covers 172 square feet. How many cans will she need to cover the court?

Answers

To find the area multiply length times width.
43 times 36 is 1548
Take 1548 divide by 172 to get the answer.
1548/172 equals 9

Answer:

Step-by-step explanation:

find the area which is length divided by width then divide by 172 which is what each can covers. So, 43x36 =1548 and 1548/172 equals 9. So 9 is the answer

Given the following function, find f(-4), f(0), and f(4).
f(x) = x + 2

f(-4)=
f(0) =
f(4)=

Answers

Answer:

-2, 2, 6

Step-by-step explanation:

f(-4)= -4+2=-2

f(0)=0+2=2

f(4)=4+2=6

Substitute x for the number in parentheses

The values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function f(x) = x + 2

To find the value of f(-4):

Plug x = -4 in the function:

f(-4) = -4 + 2 = -2

To find the value of f(0):

Plug x = 0 in the function:

f(0) = 0 + 2 = 2

To find the value of f(4):

Plug x = 4 in the function:

f(4) = 4 + 2 = 6

Thus, the values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.
