Answer:
c
Step-by-step explanation:
consider points (0,2) and (-4,0)
slope=(0-2)/(-4-0)=-2/-4=1/2
y-intercept=2
y=mx+c
y=1/2 x+2
Answer:
c = 17 Km
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
c² = 8² + 15² = 64 + 225 = 289 ( take square root of both sides )
c = 
= 17 Km
Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.
Add the length and width of rectangle A and set equal to the sum of the length and width of rectangle B.
Then solve for d.
Once you know d, substitute it in each length and width to find the actual lengths and widths.
0.7d + 1 + 1.5d - 2 = 2.5 + d + 4 - 1.3d
2.2d - 1 = -0.3d + 6.5
2.5d = 7.5
d = 3
Rectangle A:
Length: 0.7d + 1 = 0.7(3) + 1 = 2.1 + 1 = 3.1
Width: 1.5d - 2 = 1.5(3) - 2 = 4.5 - 2 = 2.5
Rectangle B:
Length: 2.5 + d = 2.5 + 3 = 5.5
Width: 4 - 1.3d = 4 - 1.3(3) = 4 - 3.9 = 0.1
True
Every rational number<span> can be written as a fraction a/b , where a and b are </span>integers<span>. ... If a </span>number<span> is a whole </span>number<span>, for instance, it must also be an </span>integer<span> and a </span>rational<span>.</span>
