Answer:

Step-by-step explanation:

hello :

note :

Use the point-slope formula.

y - y_1 = m(x - x_1) when : x_1= -3 y_1= -2 m= 1/2(parallel means same slope)

an equation in the point-slope form is : y +2 = 1/2(x+3)

$\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}$

$\longrightarrow \sf{2(1 + b) = 260}$

$\longrightarrow \sf{2(x+30+x) = 260}$

$\longrightarrow \sf{ 2x+30 = \dfrac{260}{20} }$

$\longrightarrow \sf{2x + 30 =130}$

$\longrightarrow \sf{2x = 130 - 30}$

$\longrightarrow \sf{2x = 100}$

$\longrightarrow \sf{x= \dfrac{100}{2} }$

• $\longrightarrow \sf{b= \underline{50cm}}$

$\longrightarrow \sf{= x + 30}$

$\longrightarrow \sf{= 50 + 30}$

• $\longrightarrow \sf{ \underline{80cm}}$

$\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}$

$\large\bm{Breadth= \: 50cm}$

$\large\bm{Length= \: 80cm}$

I need help on solving these types of geometry problems! Teacher said the answer is 7 but I have to show work. Thank you!

The vertex where the two triangles touch forms a pair of vertical angles, so that the angles on opposites sides of the vertex are congruent. You're shown that two legs of both triangles are congruent. All this tells you that the two triangles are isosceles, and furthermore that they are similar because of the congruence of their "base" angles.

This means

$82^\circ=m\angle 2$

$\implies82=10x+12$

$\implies10x=70$

$\implies\boxed{x=7}$

Answer:

1. The y-intercept 8 means you start off with $8. The slope 1/4 means how much money you have to pay for the amount of tickets purchased for carnival games.

2. The y-intercept 2 means the number of chapters you started reading and the slope 5/4 means the number of chapters you read per day.

3. The y-intercept 3 means the inital (start) cost of a muffin delivery and the slope 2 means the cost of each muffin delivery for the number of muffins you ordered.

Number 3 on the slope part might be the other way around if I'm wrong :)

Prove if the sum of the digits of a 3 digit number n is divisible by 9, then n is divisible by 9.

beks73 [17]

$n=100x+10y+z\\x+y+z=9k,k\in\mathbb{Z}\\\\n=99x+9y+x+y+z\\n=99x+9y+9k\\n=9(11x+y+k)$
