Which relation is a function?

Answer:

Graph C

The Y axis is up and down and the x axis is side to side. So first we want to look to see which line crosses the y axis the the up and down black line.

When you are finding a coordinate you set it up like this (x, y). You will find x first and y second.

So we are down to two graphs graph a and graph c. Know both of them cross at the (0,-7) mark but it asks for one other thing a well.

On a graph when something decreases it will go down and when something increases it will go up. So that tells me it is graph C.

Answer:

30 trees

Step-by-step explanation:

Given the policy:

8 trees are cut down 48 trees will be planted

If homeowner is going to cut down five trees on his property how many trees will be planted

Since :

8 trees cut down = 48 planted

5 trees cut down = X

Cross multiply :

8 * X = 48 * 5

8X = 240

X = 240/8

X = 30

Hence, 30 trees will need to be planted

Answer: 30

Answer:

The equation of the line that passes through the points (0, 3) and (5, -3) is [tex]y = -\frac{6}{5}\cdot x +3[/tex].

Step-by-step explanation:

From Analytical Geometry we must remember that a line can be formed after knowing two distinct points on Cartesian plane. The equation of the line is described below:

[tex]y = m\cdot x + b[/tex] (Eq. 1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

If we know that [tex](x_{1},y_{1}) = (0,3)[/tex] and [tex](x_{2},y_{2})=(5,-3)[/tex], the following system of linear equations is constructed:

[tex]b = 3[/tex] (Eq. 2)

[tex]5\cdot m + b = -3[/tex] (Eq. 3)

The solution of the system is: [tex]b = 3[/tex], [tex]m = -\frac{6}{5}[/tex]. Hence, we get that equation of the line that passes through the points (0, 3) and (5, -3) is [tex]y = -\frac{6}{5}\cdot x +3[/tex].

Answer:

Yes, 5x = y is Proportional and, the constant of proportionality is 5

Step-by-step explanation:

If x and y are proportion, then

∵ 5x = y

→ Switch the two sides

∴ y = 5x

→ Check it if passes through the origin point or not

∵ At x = 0, y = 5(0) = 0

∴ (0, 0) is a point ∈ y = 5x

∴ y = 5x represented graphically by a line passes through the origin

∴ x and y are proportion

∴ y = 5x is the equation of proportional

→ By comparing it with the form of the equation above

∴ k = 5

Answer:

A = 500(1+6%/2)^2t

Step-by-step explanation:

Given the general compound interest formula A = P(1+r/n)^nt. With an initial investment of $500, and percent interest of 6% compounded semi annually(every six months/half a year/twice in one year). A = 500(1+6%/2)^2t .

i.e if given two years of compound interest, t=2. A = 500(1+6%/2)^2(2), 500(1+0.03)^4, 500(1.03)^4, 500(1.12550881), 500(≈1.1255) = 562.75

A = 562.75$ for two years

Step-by-step explanation: the number added itself gets multiplied by two. so 3+2 then 5+4 then 9+8 then 17+16

Answer:

95°

Step-by-step explanation:

1 is opposite to 4. So, (3x+10)° = (4x-15)°

3x + 10 = 4x - 15

10 + 15 = 4x - 3x

25 = x

m(4) = 4x - 15 => 4.25 - 15

100 - 15 = 85 = m(4)

7 is opposite to 6 and 6 is parallel to 4. So, m(4) + m(6) = 180°

85° + m(6) = 180°

m(6) = 95°

6 is opposite to 7, so m(6)=m(7) and answer is 95°

Answer:

B. (2,4)

Step-by-step explanation:

Answer:

y intercept is -2.

Step-by-step explanation:

Convert the equation to slope-intercept form, or in other words, isolate the y variable. You should get y=(7/4)x-2. the -2 is the y intercept.

Answer:

a=25

angle abq=139 degrees

bcr=41

Step-by-step explanation:

(2a-9)+(5a+14)=180

7a+5=180

7a=175

a=25

2(25)-9=41

180-41=139

angle abq=139 degrees

bcr=41

Answer:

[tex]y = 2[/tex]

Step-by-step explanation:

Given

[tex]5 + y = 7[/tex]

Required

Solve

From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:

[tex]5 + y = 7[/tex]

[tex]-5 + 5 + y = 7 - 5[/tex]

[tex]0 + y = 2[/tex]

[tex]y = 2[/tex]

Answer:

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

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line

Answer:

A will be at -3.3 B will be at -4.1 C will be at 6.1 D will be at 1.3 hope this helps

Answer:

Step-by-step explanation:

x        - the first number

2x      - two times the first number

2x-9     - 9 less than two times the first number = the second number

3x      - three times the first number

3x+6     -  six more than three times the first number = the third number  

The sum of three numbers is 123:

x + 2x-9 + 3x+6 =123

    6x - 3 = 123

      6x = 126

        x = 21

2x-9 = 2•21-9 = 33

3x+6 = 3•21+6 = 69

Check:  21+33+69 = 123
