There will be only 2 digits because 588 divided by 6 is 98. Since the 9 is in the tens place and the 8 is in the ones place.
Answer:
(1,2)
Step-by-step explanation: The x = 1 and the y = 2
Answer:
The area of the lawn is 68
.
Step-by-step explanation:
Area of lawn = Area of garden - (Area of triangle + Area of trapezium)
Area of garden = length x width
= 14 x 10
= 140 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
Area of triangle =
x base x height
=
x 3 x 8
= 12 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
Area of trapezium =
(a + b) h
=
(5 + 7) 10
= 60 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
So that;
Area of lawn = 140 - (12 + 60)
= 140 - 72
= 68 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
The area of the lawn is 68
.
Answer:
A. ![\frac{17}{25} -\frac{19}{25}i](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B25%7D%20-%5Cfrac%7B19%7D%7B25%7Di)
Step-by-step explanation:
To divide the complex number:
, we rationalize with the conjugate of the denominator.
This gives us:
![\frac{5-i}{4+3i} *\frac{4-3i}{4-3i}](https://tex.z-dn.net/?f=%5Cfrac%7B5-i%7D%7B4%2B3i%7D%20%2A%5Cfrac%7B4-3i%7D%7B4-3i%7D)
![=\frac{(5-i)(4-3i)}{(4+3i)(4-3i)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%285-i%29%284-3i%29%7D%7B%284%2B3i%29%284-3i%29%7D)
We apply the distributive property to get:
![\frac{20-15i-4i+3i^2}{4^2+3^2}](https://tex.z-dn.net/?f=%5Cfrac%7B20-15i-4i%2B3i%5E2%7D%7B4%5E2%2B3%5E2%7D)
We simplify to get:
![\frac{20-19i+3(-1)}{(16+9)}](https://tex.z-dn.net/?f=%5Cfrac%7B20-19i%2B3%28-1%29%7D%7B%2816%2B9%29%7D)
This implies that:
![\frac{20-19i-3}{(16+9)}](https://tex.z-dn.net/?f=%5Cfrac%7B20-19i-3%7D%7B%2816%2B9%29%7D)
![\frac{17-19i}{25} =\frac{17}{25} -\frac{19i}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B17-19i%7D%7B25%7D%20%3D%5Cfrac%7B17%7D%7B25%7D%20-%5Cfrac%7B19i%7D%7B25%7D)
The correct answer is A.
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.
