Answer:

Therefore, the solution of the system of equations will be:

x=5,\:y=-1

Step-by-step explanation:

Given the system of equations

x-y=6;\:y=-1

solving

\begin{bmatrix}x-y=6\\ y=-1\end{bmatrix}

\mathrm{Subsititute\:}y=-1

\begin{bmatrix}x-\left(-1\right)=6\end{bmatrix}

\begin{bmatrix}x+1=6\end{bmatrix}

Isolate x for x+1=6

x+1=6

x=5

Therefore, the solution of the system of equations will be:

x=5,\:y=-1

50 POINTS!!
Charra [1.4K]

Answer:

FH=73

Step-by-step explanation:

We are given that a segment FH and G is the midpoint of FH.

FH=14x-4

FG=5x+9

We have to find the measure of FH.

When G is the midpoint of segment FH

Then , FG=GH

FH=FG+GH

Segment addition property

14x-4=FG+FG

Substitution property

14x-4=2FG

14x-4=2(5x+9)

14x-4=10x+18

14x-10x=18+4

4x=22

x=\frac{22}{4}=5.5

Substitute the values then we get

FG=5(5.5)+9=36.5

FG=GH=36.5

FH=14(5.5)-4=73

The table below shows the number of miles Maggie ran and the number of calories she burned.
gulaghasi [49]

Answer:

The dependent variable is number of calories burnt.

Step-by-step explanation:

The dependent variable of an experiment is the variable under study, i.e. it is the variable that is being observed for any changes, when the other variables are changed.

The independent variable is the variable that is being altered to observe the changes in the dependent variable.

A dependent variable can be affected by one or more than one independent variables.

In this case, the data provided represents the number of calories Maggie burned based on the number of miles she ran.

So, the amount of calories burnt is dependent upon the number of miles covered running.

So, the dependent variable is the number of calories burnt and the independent variable is the number of miles she run.

Thus, the dependent variable is number of calories burnt.
