Answer:

x = 30°, y = 90°

Step-by-step explanation:

$(y + x) + (y - x) = 180 \\ 2y = 180 \\ y = 90 \\$

$2x + y + x = 180 \\ 3x + 90 = 180 \\ 3x = 90 \\ x = 30$

Which point would be a solution to the system of linear inequalities ?

brilliants [131]

Answer:

(12,-6)

Step-by-step explanation:

we have

$y\leq \frac{4}{3}x+5$ ----> inequality A

$y\geq -\frac{5}{2}x+5$ ---> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)

Verify each point

Substitute the value of x and the value of y of each ordered pair in the inequality A and in the inequality B

case 1) (0,-1)

Inequality A

$-1\leq \frac{4}{3}(0)+5$

$-1\leq5$ ----> is true

Inequality B

$-1\geq -\frac{5}{2}(0)+5$

$-1\geq 5$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 2) (0,3)

Inequality A

$3\leq \frac{4}{3}(0)+5$

$3\leq5$ ----> is true

Inequality B

$3\geq -\frac{5}{2}(0)+5$

$3\geq 5$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 3) (-6,-6)

Inequality A

$-6\leq \frac{4}{3}(-6)+5$

$-6\leq-3$ ----> is true

Inequality B

$-6\geq -\frac{5}{2}(-6)+5$

$-6\geq 20$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 4) (12,-6)

Inequality A

$-6\leq \frac{4}{3}(12)+5$

$-6\leq21$ ----> is true

Inequality B

$-6\geq -\frac{5}{2}(12)+5$

$-6\geq -25$ ----> is true

therefore

The ordered pair is a solution of the system (makes true both inequalities)

Find g Write your answer in simplest radical form

a_sh-v [17]

Answer:

g = 7 yards

Step-by-step explanation:

you have 7 $\sqrt{3}$ yards for the angle adjacent 30 deg.

tan 60 = $\sqrt{3}$

tan 60 = 7 $\sqrt{3}$ / g

7 * root(3) / g = root(3)

7/g = 1

g = 7 yards

You download eight songs onto a music player. If you play three of the songs using the random shuffle option, how many ways can

Dmitrij [34]

Every time you play a song 8 different songs can be played, since you do this 3 times:
$8 \times 8 \times 8 = 512$
Or, an easier way to write this if play them many times:
${8}^{3} = 512$
In which the 8 is how many options and the 3 how many times you play.
