Answer:

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified

Step-by-step explanation:

Given:

m angle 1 = ( 3x + 10 )°

m angle 2 = ( 5x - 4 )°

To Find:

m∠1 = ?

m∠2 = ?

Solution:

Vertical Angles:  

The angles opposite each other when two lines cross. They are always equal.

∴ m Angle 1 = m Angle 2

Substituting the given values we get

3x+10=5x-4\\\\2x=14\\\\x=\dfrac{14}{2}=7\\\therefore x =7

Substituting ' x ' in Angle 1 and Angle 2 we get

m Angle 1 = 3 × 7 + 10 = 31°

m Angle 2 = 5 × 7 - 4  = 31°

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified

Brianna has x nickels and y pennies. She has no less than 20 coins worth no more
Bond [772]

Answer:

y \ge 20 - x

y \le 80 -5x

(x,y) = (15,5)

Step-by-step explanation:

Given

Nickels = x

Pennies = y

Amount = \$0.80 maximum

Coins = 20 minimum

Required

Solve graphically

First, we need to determine the inequalities of the system.

For number of coins, we have:

x\ +\ y\ge 20 because the number of coins is not less than 20

For the worth of coins, we have:

0.05x\ +\ 0.01y\ \le0.80 because the worth of coins is not more than 0.80

So, we have the following equations:

x\ +\ y\ge 20

0.05x\ +\ 0.01y\ \le0.80

Make y the subject in both cases:

y \ge 20 - x

0.01y \le 0.80 - 0.05x

Divide through by 0.01

\frac{0.01y}{0.01} \le \frac{0.80}{0.01} -\frac{ 0.05x}{0.01}

y \le \frac{0.80}{0.01} -\frac{ 0.05x}{0.01}

y \le 80 -5x

The resulting inequalities are:

y \ge 20 - x

y \le 80 -5x

The two inequalities are plotted on the graph as shown in the attachment.

y \ge 20 - x --- Blue

y \ge 80 -5x --- Green

Point A on the attachment are possible solutions

At A:

(x,y) = (15,5)
