Answer:

Explicit formula: y=3x+11

How tall will the plant be after 6 months? 29 inches

Step-by-step explanation:

Since it grows 3 inches per month, the slope would be 3, and since Gianna planted it when it was 11 inches already, the y-intercept would be 11.

plug in 6 for x (for 6 months): 3(6)+11=29

How to combine like terms
aev [14]

Example: 1x+2y+3z+4a+5x+6y+7z+8+9

We can see that there is more than one number with the variable x, therefore, we say they're ''like terms'' and because of that they can be summed. We do this with all of the other numbers with similar variables. If no numbers with similar variables are left, like 4a, you don't do anything but write them as they are. You can also see that 8 and 9 can also be summed because neither of them has a variable, therefore they're similar.

In this step, you just do the operation with the numbers and keep the same variable.

(1x+5x)+(2y+6y)+(3z+7z)+4a+(8+9)

(6x)+(8y)+(10z)+4a+(17)

since there are not more numbers similar in variables, this operation is done.

6x+8y+10z+4a+17

In parallelogram FGHJ if m∡ GHJ=55˚ find m∡FGH
hodyreva [135]

Answer:

∠ FGH = 125°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, then

∠ FGH + ∠ GHJ = 180° , that is

∠ FGH  + 55° = 180° ( subtract 55° from both sides )

∠ FGH = 125°

Which pairs of variables have a linear relationship? Select
Neko [114]

Answer:

Side length and perimeter of 1 face

Area of 1 face and surface area

Step-by-step explanation:

Suppose you are given cube with side length of x units.

Then

Side length = x units

Perimeter = 4x units

Area of 1 face =x^2 square units

Surface area =6x^2 square units

Volume =x^3 cubic units

A linear relationship is any equation that, when graphed, gives you a straight line.

Consider all options:

A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function y=kx is a straight line.

B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation y=kx^2.

C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation y=kx^{\frac{3}{2}}.

D. Area of 1 face and surface area is a linear relationship, because the graph of the function y=kx is a straight line.

E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation y=kx^3.
