Point of intersection is: (6,80)

Step-by-step explanation:

In order to find the point of intersection for two lines we solve the equations.

Given equations are:

$y = 10x+20\ \ \ Eqn1\\y = 5x+50\ \ \ Eqn2$

Putting y = 5x+50 in equation 1

$5x+50 = 10x+20\\50-20 = 10x-5x\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6$

Putting x=6 in equation 1

$y = 10(6)+20\\y = 60+20\\y = 80$

Hence,

Point of intersection is: (6,80)

Question 4 <br> Use the figure below to find the value of x and y

Tpy6a [65]

Answer:

$x=4, y=8$

Step-by-step explanation:

step 1

Find the value of y

we know that

In the right triangle of the figure

$cos(30\°)=\frac{4\sqrt{3}}{y}$

Remember that

$cos(30\°)=\frac{\sqrt{3}}{2}$

$\frac{\sqrt{3}}{2}=\frac{4\sqrt{3}}{y}$

Simplify

$y=8\ units$

step 2

Find the value of x

In the right triangle of the figure

$sin(30\°)=\frac{x}{8}$

Remember that

$sin(30\°)=\frac{1}{2}$

$\frac{1}{2}=\frac{x}{8}$

$x=4\ units$
