Hope this makes sense.
Answer: a) y=-29x-20 b) y=3/5x-18
Step-by-step explanation:
a) m = (-49-38)/(1 - (-2)) = -87/3 = -29
y=-29x+b --> Substitute (1,-49) as a point
(-49)=-29(1)+b
-49=-29+b
-b=-29+49
b=-20
Therefore, the equation of the line is y=-29x-20
b) m = (-18-(-9)/(0-15)) = -9/-15 = 3/5
The y-intercept is (0,-18) as it's where the line intersects the y-axis and x equals 0
Therefore, the equation of the line is y=3/5x-18
Answer:
40 square units
Step-by-step explanation:
First of all, lets say that square has side
, so, the area unit is ![l^2](https://tex.z-dn.net/?f=l%5E2)
the diagonal's square is ![l\sqrt{2}](https://tex.z-dn.net/?f=l%5Csqrt%7B2%7D)
CALCULATION OF TRIANGLES'S AREA (there are 4 triangles)
![A_{triangles}=4*base*heigh*0.5=2*(l\sqrt{2} )(2l\sqrt{2} )=8l^2](https://tex.z-dn.net/?f=A_%7Btriangles%7D%3D4%2Abase%2Aheigh%2A0.5%3D2%2A%28l%5Csqrt%7B2%7D%20%29%282l%5Csqrt%7B2%7D%20%29%3D8l%5E2)
CALCULATION OF MAIN SQUARE AREA
![A_{square}=side*side=(4\sqrt{2} l)(4\sqrt{2} l)=32l^2](https://tex.z-dn.net/?f=A_%7Bsquare%7D%3Dside%2Aside%3D%284%5Csqrt%7B2%7D%20l%29%284%5Csqrt%7B2%7D%20l%29%3D32l%5E2)
TOTAL AREA
![A_{total}=A_{triangles}+A_{square}=8l^2+32l^2=40l^2](https://tex.z-dn.net/?f=A_%7Btotal%7D%3DA_%7Btriangles%7D%2BA_%7Bsquare%7D%3D8l%5E2%2B32l%5E2%3D40l%5E2)
Answer: x-3, 3, is not equal to
Step-by-step explanation:
Answer:
The easiest way to convert a fraction to a decimal is to divide the numerator (the top of the fraction) by the denominator (the bottom of the fraction) by using a calculator. The resulting answer will be the value of the fraction expressed as a decimal number.
