<h3>Answer: Altitude</h3>

Explanation:

An altitude goes from a vertex point to the opposite side, such that it is perpendicular to the opposite side. The square angle marker indicates we have a 90 degree angle, so DB is perpendicular to AC. The altitude of a triangle, DB, is the height of the triangle with base AC. The base and height are always perpendicular to one another.

Pepsi [2]

Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The coins are in the ratio 2:5:7 respectively. If he has a R90 in R2 coins. If x represent the total coins, hence:

(5/14) * x = 90

x = 252

Number of R5 coins = (2/14) * 252 = 36

Number of R1 coins = (7/14) * 252 = 126

Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins,

Suppose tanΘ = 3/5, and that Θ is in quadrant I. Find tan2Θ.

In-s [12.5K]

Answer:

15/8

Step-by-step explanation:

tan 2θ = 2 tan θ / (1 − tan² θ)

tan 2θ = 2 (3/5) / (1 − (3/5)²)

tan 2θ = (6/5) / (1 − 9/25)

tan 2θ = (6/5) / (16/25)

tan 2θ = (6/5) × (25/16)

tan 2θ = 15/8

Choose the solution(s) of the following system of equations x2 + y2 = 6 x2 – y = 6

ElenaW [278]

<h2>Answer</h2>

$x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1$

Or as ordered pairs: $(\sqrt{6} ,0),(-\sqrt{6} ,0),(\sqrt{5} ,-1),(-\sqrt{5} ,-1)$

<h2>Explanation</h2>

Lets solve our system of equations step by step

$x^2+y^2=6$ equation (1)

$x^2-y=6$ equation (2)

1. Solve for $x^2$ in equation (2)

$x^2-y=6$

$x^2=6+y$ equation (3)

2. Replace equation (3) in equation (1) and solve for $y$

$x^2+y^2=6$

$6+y+y^2=6$

$y^2+y=0$

$y(y+1)=0$

$y=0$ or $y=-1$

3. Replace the values of $y$ in equation (3) and solve for $x$

- For $y=0$

$x^2=6+y$

$x^2=6$

$x=\sqrt{6}$ or $x=-\sqrt{6}$

- For $y=-1$

$x^2=6+y$

$x^2=6-1$

$x^2=5$

$x=\sqrt{5}$ or $x=-\sqrt{5}$

So, the solutions of our system of equation are:

$x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1$
