Answer:

(1,-1)

Step-by-step explanation:

You would graph y=-2x+1 by starting the graph at (0,1) then placing another point at (-1, 3) and drawing a straight line through those points. You would graph y=-5x+4 by starting the graph at (0,4) then placing another point at (-1, 9) and drawing a straight line through those points. The answer would be where the two graphs intersect which is (1,-1).

The selling price of a​ refrigerator, is ​$ 796.40 . If the markup is 10 % of the​ dealer's cost, what is the​ dealer's cost of
8_murik_8 [283]

The final price (what it is selling for) is $796.40

The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.

We need to find the original price.

We write this as an equation

The original price *110% = final price

This is because the original price is itself (100%) added with 10%

Plug in the known final price

Original Price * 110% = 796.40

Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers.

Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)

110% = 1.1

So it is now

Original price *1.1 = 796.40

Divide both sides by 1.1 to isolate our unknown, the original price

Original price = $724

Help me i’m stressed
Aleks04 [339]

Answer:

<h3>m∠1 = 41°</h3><h3>m∠2 = 41°</h3>

Step-by-step explanation:

<h3>m∠1 = m∠2</h3>

{(6x + 11)}^{o}   =  {(10x - 9)}^{o}  \\ 11 + 9 = 10x - 6x \\ 20 = 4x \\  \frac{20}{4}  =  \frac{4x}{4}  \\ 5 = x \\

x = 5°,

m∠1 = (6x + 11)°

{(6x  + 11)}^{o}  \\ 6(5) + 11 \\ 30 + 11 \\  {41}^{o}  \\
