The solution is (1,1)

Step-by-step explanation:

The system of linear equation is

y=-3x+4 and y+\frac{1}{3} y=\frac{4}{3}

Using substitution method, let us substitute y=-3x+4 in the equation

y+\frac{1}{3} y=\frac{4}{3}

-3 x+4+\frac{1}{3}(-3 x+4)=\frac{4}{3}

Multiplying the term -3x+4 by \frac{1}{3}, we get,

-3 x+4-x+\frac{4}{3}=\frac{4}{3}

Subtracting both sides by \frac{4}{3},

-3x+4-x=0

Simplifying, we get,

\begin{aligned}-4 x+4 &=0 \\-4 x &=-4 \\x &=1\end{aligned}

Now, substitute x=1 in y=-3x+4

y=-3(1)+4\\y=-3+4\\y=1

Thus, the solution is (1,1)

Suppose two parallel lines are cut by a transversal. What angle relationships describe congruent angles in this context?
baherus [9]

Answer:

Corresponding angles

Step-by-step explanation:

In elementary geometry the word congruent is often used as follows.

Two line segments are congruent if they have the same length.

Two angles are congruent if they have the same measure.

Two circles are congruent if they have the same diameter.

The eight angles that are produced as a result of two parallel lines are cut by a transversal will together form four pairs of corresponding angles. Corresponding angles are congruent. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs.

if the input value is negative, is the output value of f(z)=-4z+12 always positive or always negative?
expeople1 [14]
If the input value is negative, the output value is always positive.  We know this because the negative sign before the 4z will always reverse the negativity of the number that is plugged in.

For each boat he sells, nick earns $149 in addition to 2% of the purchase price of the boat as commission. If p represents the p
muminat

Answer:

The equation c = 0.02p+149 represents micks commission.

Step-by-step explanation:

Given that:

Amount earned by Nick on sale of each boat = $149

Commission earned = 2% of the purchase price

p represent the purchase price

Commission earned = \frac{2}{100}*p

Commission earned = 0.02*p

Commission earned = 0.02p

Total commission = c = 0.02p + 149

Hence,

The equation c = 0.02p+149 represents micks commission.
