What is the solution to the system of equations represented by the two equations?
Iteru [2.4K]
If you would like to solve the following system of equations, you can do this like this:

y = - 2 * x + 7
y = 1/3 * x
____________
1/3 * x = - 2 * x + 7
1/3 * x + 2 * x = 7
1/3 * x + 6/3 * x = 7
7/3 * x = 7      /*3/7
x = 7 * 3 / 7
x = 3

y = 1/3 * x = 1/3 * 3 = 1

The correct result would be: x = 3 and y = 1.

A runner runs 8 miles in 92 minutes. What is the runners unit rate?
KiRa [710]

For this case, what we must do is calculate the speed of the runner.

We have then that the speed is given by:

v =\frac{d}{t}

Where,

d: distance

t: time

Substituting values we have:

v = \frac{8}{92}

V = 0.09 \frac{miles}{minutes}

Answer:

the runners unit rate is:

V = 0.09 \frac{miles}{minutes}

Solve the following equation for D. Be sure to take into account whether a letter is capitalized or not. fD - 7 = q^2
Alecsey [184]

Answer:

\displaystyle D=\frac{q^2+7}{f}

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

fD - 7 = q^2

It's required to solve the equation for D. All letters must preserve their capitalization.

We must isolate the letter D by removing from the left side all the terms and coefficients that surround it.

Adding 7:

fD = q^2+7

Dividing by f:

\mathbf{\displaystyle D=\frac{q^2+7}{f}}
