The given equations y = -2x + 4 and 7y = -14x + 28 has infinitely many solutions

<h3><u>Solution:</u></h3>

Given that two equations are y = -2x + 4 and 7y = -14x + 28

We have to find number of solutions for this set of equations

Let us first solve the given equations

y = -2x + 4 ---- eqn 1

7y = -14x + 28 ---- eqn 2

Substitute eqn 1 into eqn 2

7(-2x + 4) = -14x + 28

-14x + 28 = -14x + 28

0 = 0

Thus means given equations has infinitely many solutions

The two lines may have an infinite number of intersecting points (infinite solutions).

If Q is the midpoint of segment PR, PQ = 17 cm, then what is the total length of PR?

Tpy6a [65]

Answer:

34 cm

Step-by-step explanation:

PR = PQ + QR

PQ = QR because Q is the mid-point

Since PQ = 17 cm, then QR = 17 cm

so,

PR = 17 + 17

PR = 34 cm

Solve the system by substitution.

kirill [66]

<h2>Answer:</h2>

x = 1

y = 1

<h3>Step-by-step explanation:</h3>

$y=-3x+4\\ y=x$

Substitute into one of the equations

$-3x+4=x$

Rearrange variables to the left sider of the equation

$-3x-x=-4$

Combine like terms

$-4x=-4$

Divide both sides of the equation by the coefficient of variable

$x=\frac{-4}{-4}$

Determine the sign for multiplication or division

$x=\frac{4}{4}$

Cross out the common factor

$x=1$

Substitute into one of the equations

$y=1$

The solution of the system is

$\left \{ {{x=1} \atop {y=1}} \right.$
